Singulair and allergist

I have an 8 yr old son that has allergies and asthma. The allergist recently prescribed Singulair which my son had taken when he was 5. We took him off of it back then due to anger outbursts. By the way, the Dr. said that was not a side effect, but nonetheless the issues subsided. When it was recently added back to his medication list, within 3 days he had anaphylactic type episodes 2 days in a row. The attack started with stomach pains, chest pains and then he couldn't breath AT ALL and turned blue! There was no time to call 911 so I gave him an Epi Pen. The attacks are still occurring yet milder and all his Dr.'s swear by Singulair and think I am crazy. I took him off Singulair immediately and we are still waiting for it to leave his system. I think that is why the recent episodes have been milder. He has been tested for all sorts of allergens which he did not come in to contact with prior to the anaphylactic events. We still have no answers and if I hear one more Dr. talk about how great Singulair is, I am going to freak out!! To heck with these drug companies and doctor's who get perks for prescribing medications without informing us of side effects.

I am absolutely ecstatic to have found this webpage, although I feel like I have lost YEARS of my life to this drug. After reading the online article from The Plain Dealer (newspaper), my mom urged me to stop taking this medication.

I am 25 years old and have been on this medication since I was 12 years old. Over the years I have had NUMEROUS problems including migraines, chronic vertigo, anxiety, severe insomnia, irritability, urticaria, hives, eczema, and all sorts of GI issues ranging from GERD to diarrhea.

I have seen an allergist, a neurologist, a GI specialist, a family physician, a physical therapist (for the vertigo) and have had countless medical procedures ranging from MRI's to endoscopies.

I am horrified that ALL of these problems have stemmed from this one drug. I will NOT be taking my prescribed dosage before bed tonight and will be calling my allergist in the morning to inform them that I am going to quit taking Singular.

Thank you all for your support and for sharing your stories!

Worst night of my life--woke up feeling filled with anxiety, insomnia, had to get up repeatedly to urinate, felt very agitated, though I felt very peaceful & relaxed at bedtime, feet were swollen so badly I couldn't put on my shoes. I took 10 mg of Benadryl, which did not change how I felt. My internist took me off the Singulair immediately, when I contacted him the next morning.

Despite being on an antidepressant which was recently increased, very recently I felt sad, anxious, and was crying all the time, felt irritable, and was chronically tired. I took 400mg of gabapentin (Neurontin), prescribed for nerve pain, numbness, tingling in both hands & feet at 9 p.m. Just before bedtime at 10:00 I'd take 10 mg Singulair. 1-2 hours later I was wide awake, sometimes not sleeping for hours or at all, even after taking 1-2 Benadryl, without the dyes.

Over the past two years I've had eczema, for which I saw 2 different dermatologists and an infectious disease specialist. Eczema was so bad, I couldn't sleep at night. I consulted with every imaginable doctor, including the allergist who prescribed Singulair & was told it couldn't be the Singulair because Singluair was FOR ALLERGIES. Was diagnosed with fibromyalgia by a neurologist, recently had a repeat of an MRI because I couldn't walk the pain was so bad. My neurologist was unable to find any reason I had pain & difficulty walking, after reviewing the results of the MRI.

I've seen my internist for heart palpitations. When I reported urinary frequency, he had me get a cystocopy (negative) because I had hematuria, blood in my urine, and I had weight loss.

I still have many of the side effects, like the numbness & tingling in my feet and hands, however, I am able to sleep through the night and did so immediately after going off the Singulair. A lot of the fibromyalgia pain I was having has subsided, depression, anxiety has subsided as well.

Extreme aggression and anger in my 2 year old. He has been on singulair for six months now and has been kicked out of two schools for biting and hitting for no reason(sometimes when the victim was asleep). Our allergist told us to take him off the drug three days ago and we can already see much improvement.

I have just started my son on Singulair about 1 1/2 weeks . ago. He is also on Allegra plus using the Nasonex. The allergist did warn about all the things that have been reported about this drug. We still decided to try it to see how he responds to it. The number one thing we have noticed is: it has really made a difference in him with his allergies for the good. As in all the things we have heard about behavior issues with others, we have seen an increase in his energy and hyperness but not enough to alarm us yet. We have decided to keep him on it until we see a difference that we feel he is in any kind of danger or anyone else. Hopefully this will not be the case, we all are just getting our exercise which we did prior with him anyways. I hope that a few more positive reports come in, taking any kind of drug you run the risk of side effects. I'm not a fan of taking them but right now they help my son breathe and enjoy being outside where kids should be playing and loving life.

My son now age nine went off Singulair two years ago. He was one it for about a year and was having terrible nightmares. I did not realize why until he went off of it. A year later the doctor put him back on it. I forgot and was not quite sure it was the Singulair so we tried again. About 2 months later it started again. I quickly remembered and took him off. When I asked the doctor I was told it is a rare side effect. I am happy to see this site so others know and can become aware. My daughter however has been on it for years and had done well. We are trying to take her off though because she seems very nervous and anxious (more than typical). I want to see if the medicine makes a difference.

My son used a nebulizer 2 to 4 times a day every day from the time he was one and a half years old. When he had just turned three his doctor prescribed Singulair. It was like a wonder drug for us! It took care of his asthma and we didn't have to use the nebulizer any more. He's been on it ever since -- he's 10 now -- he also takes zyrtec and has a rescue inhaler that he uses maybe once a week. About every other year he requires a course of steroids and a week of regular nebulizer use. Also, for the past year he has also required a daily inhaled steroid.
Now, about his mood issues. My son has always been sensitive and intense, moody. The first time I became alarmed was when he was 7, and he told me he wanted to burn his hands on the stove to punish himself for forgetting his homework. I consulted a psychologist who evaluated him and said he was not clinically depressed. Since then he has had periodic "dark" episodes -- especially in the winter. He has said he wants to die. He has had crying jags over things that are upsetting (loss of a pet was the worst) but it seems excessive for him to be saying he "just wants it all to end." He has told me that he is always unhappy and that he hates himself. He has also had problems with moody acting-out with friends. He will brood about hurt feelings until he loses his temper and screams at the friend. I have worked very hard with him on learning to manage his emotions. He hit a friend at school who was teasing him. He accepted his consequences willingly and willingly wrote letters of apology -- he told me he thinks he has anger problems and doesn't want to be this way. And his character is that he is a sweet, caring boy who can't stand to see anyone hurt, but also can't stand to be hurt.
A couple of years ago I asked his allergist if any of the meds he's on are linked with depression. He said no. We have a family history of depression, and I thought my son had gotten the worst combo of all the genes.
Recently, this all got to the point that I decided he needed to see a psychiatrist and quite possibly take medication for depression. Before I made the appointment he had a check-up with his allergist. Going down his list of meds the dr. said, recently Singulair has been linked with depression, have you noticed any moodiness or sadness? My first thought was that I have, but that he's always been like this. My 2nd thought was that he has been on Singulair for most of his life. I said yes and that I'd like to try him off of it.
My son resisted going off of it. He has had enough negative experiences with asthma that he didn't want to risk it, but I insisted. I didn't expect to see any change, but I thought it was important, as I was going to take him to a psychiatrist to consider depression meds, to see how he did off of it for a couple of months.
Less than a week later, he had been in a wonderful mood -- to the point of being silly and giddy all evening -- for 3 days in a row. The kind of mood that I don't see him in often, and when I do I think to myself, "he should be like this more often." One evening he even realized he had forgotten to bring home a homework assignment. I thought, "oh no, here we go, his evening is ruined." But he talked through his options with me, looked a little uncertain, and said, well, okay, I guess I'll have to tell my teacher I don't have it. I'll tell her I'll make it up at lunch if she wants me to. That was it! He didn't mention it again. I didn't say anything about his mood, because I really don't think I can know anything after just a few days -- it could be coincidental. The next day, he said to me that he thinks being off the Singulair is "working." He has now told me that a couple of more times.
I am tentative, but amazed. Even if my son does have a predisposition to be depressed, maybe the Singulair was making everything worse, and things really can improve for him. I am afraid to be to hopeful. At the same time, I feel guilty for giving this medicine to him for 7 years without a second thought.
As an aside, my son has periodically complained of leg pains, that I always told him were growing pains.
I would love any feedback that anyone can give me. So far (these two weeks), his asthma has been controlled with pulmacort, zyrtec and albuterol, so that aspect is okay.

I have had two sons on Singular. My three-year old had drastic behavioral changes about a month after starting to take Singulair. He suddenly had severe separation anxiety, was crying and whining all the time, did not want to be alone at all. Normally he is very happy go lucky and we did not see his bright cheerful smile for weeks. I took him to his pediatric doctor and described the behavior and she immediately said to take him off the Singulair. After two weeks, he was back to his normal, happy self. My older son is 5 and has been on Singulair for over a year. I consulted with his allergist right away after my 3-year-old was having trouble. I wanted to take him off the Singulair and he advised against it, because my 5 year old has more serious asthma and allergies. When he first started he had nightmares, and when I mentioned it to a friend whose son is also on Singulair, she said, oh, give it to him in the morning instead of night and that will help with the nightmares. That did help. Yesterday, I decided to take him off of it. It seems like he's always coughing and congested, he complains often of growing pains in his legs that will make him scream and cry and beg for medicine to make the pain go away. He becomes emotionally uncontrollable - i.e. he will have crying jags and when I try to console him or ask him to stop crying he'll say he can't help it and he'll say, "You don't understand, I can't control it." He has also complained of headaches and I wondered how would a 5-year-old even know what a headache is? I feel very naive and am thankful for sites like this because you will not always get this information from your health care providers and also the drug companies. If you are like me, and you've ended up in the emergency room and also calling 911 because your child is having and asthma attack, you be be so afraid you'll give your kids whatever the doctor prescribes and you'll look at it as the lesser of two evils - do you want to be in the emergency room or can you live with the side effects. It has taken me a while to get smart about this. There has to be a better solution out there.

My 6 1/2 year old daughter has been on Singulair for 3 1/2 to 4 years now and we have had horrible experiences! She was having night terrors, mood swings, angry issues, self control issues, crying over small things, etc. We have been to psychiatrists and psychologists who have diagnosed her with mood disorder, sensory processing disorder and anxiety disorder! Well she has recently been having stomach problems so we have been going to a GI to figure that out. I got online to research and found numerous sites that told how Singulair causes all these things in children. We took my daughter off the meds and within 3 or 4 days seen a tremendous difference! She is a totally different child! It just really frustrates me and saddens me that all these children and their families are going through all this and the doctors do not seem to care. The allergist or psychiatrist didn't believe me. They say no study has ever proven such things. I don't care what they say we as parents know our children and we are the experts when it comes to seeing how they change when on this medicine, we are the ones that live with them and are with them everyday not the doctors! I think they just don't want to lose out on their money from prescribing this drug 90% of children with allergies and asthma!

I wrote a post few days ago about Singulair and how great my daughter is doing since she started to take this medication three months ago.
Then I started reading about all the side effects that other children had because of Singulair. I GOT SO SCARED!
So scared that last night I stopped giving Singulair to my daughter.

From January to September my daughter had asthma every other week. She was put on steroids (prednisolone) every time she couldn't breath. Then in September the pulmonologist said we have to take control of the situation because so much steroids can damage a little body.
She made me feel I had been a terrible mothers since I always refused to give her singulair.
She convinced me and then I started Singulair, but now I feel worst because I have the feeling I am giving poison to my daughter even if her asthma is under control.

My 7 years old stopped Singulair 12 hours ago, I do not know what is going to happen now. Of course I cannot call the pulmonologist anymore in case my ds gets bad.
Somebody here said that she is giving her son Nordic Naturals Fish Oil, Culturelle probiotics, vitamin c, and changing his diet - increased magnesium and decreased dairy.I will love to have more information about this alternative way of controlling asthma. I do not remember who wrote this post. If there is a web site of a doctor I can contact i will do right away. I live in New York.

I need help. Thank you so much.

My three year old daughter was on in as a baby and it was great for her asthma. I stopped it for a year and now she is 3 and has started it again about two weeks. She sleeps at least 12hrs a night and has a nap. This is someone who slept maybe 8hrs a night and never a nap. Actual the sleep is so much its kinda worrying me. I have a hard time even waking her up. What should I do?

My 4 year old son started taking singulair when he was two. I don't think I picked up on his behavior change right away b/c I thought that he was just entering the "terrible two's". But over time, his allergist added on Nasonex (I know the docs say that it doesn't cause side-effects b/c it's a nasal spray, but I don't buy that...it's a steroid, plain and simple) and more recently zyrtec was added on for his hives. Well, the zyrtec was the straw that broke the camel's back. I mean, he has been a real "handful" since the singulair, but after zyrtec was added 5 months ago - let's just say he was completely out of my control. His meltdowns were so bad that I couldn't go ANYWHERE with him. I either got a sitter or just didn't go anywhere. He became aggressive, defiant, emotional, unhappy. And to top it off he started to have serious "autistic-like" self-stimulatory behaviors (grinding teeth, squinting eyes shut, flapping his hands, punching himself...). At this point my life had become a complete nightmare, and my poor 10 month old son was getting NO attention b/c my 4 year old was so out of control and aggressive. I was afraid for the baby's safety...oh, I could go on all night. This medication has impacted my marriage, my finances, my sanity. Shortly after he started Singulair I had to go on an antidepressant b/c it too so much out of me just to be his mommy. Anyway, a week ago I had him scheduled for a psych evaluation (thought for sure we were going to walk away with either autism or bipolar diagnosis), but two days before I decided to look up the meds he is on and BINGO! All of these posts sound like what we have been going through. I stopped all of his meds that night, cold-turkey, and he has been the most pleasant little boy I have ever met!! My husband and I have fallen in love with him over the past week - we had no idea he was such a sweet child.

Now, while I'm ecstatic that we have found the answer to our nightmare, I also feel SO STINKIN' ANGRY! We lost out on 2 years with our sweet boy, there were times when we raised our voices at him when he just couldn't help himself - he was suffering inside!! When I went to talk to the allergist about my findings this past week, he said, "well, maybe he just had a good day. I'd like to see what happens if he goes off all his meds for a week". Well, there you have it, he has been off for one week and he's an absolute angel. He has an amazing heart and is so caring!!!

Singulair is awful (and so is zyrtec). Please don't give this drug to your children. Research other alternatives (I am giving my son Nordic Naturals Fish Oil, Culturelle probiotics, vitamin c, and am changing his diet - increased magnesium and decreased dairy. I came up with this after hours of research...).

There is a woman on this site whose daughter committed suicide after 3 years on Singulair. This is no joke and the FDA needs to get with it.

BTW, I used to date a Singulair rep (I knew there was something I didn't like about that guy:)

My son is 3 and has been on Singulair since around springtime (I think... I've lost count). Anyway, during this summer we noticed his behavior had just gone straight to hell. At first I was attributing it to the wonderful world of the three year old, but it was just getting ridiculous. He was having countless meltdowns, screaming bloody murder (I mean SCREAMING to the point of going hoarse), hitting, punching, slamming, banging, crying hysterically for ridiculous reasons, yelling out during the night, and showing OCD behaviors. I was fearing that he might have ADHD/OCD until my husband stumbled upon this website. I remember hearing stories about teenagers having horrible side effects from singulair, but didn't think it was affecting my son at 3. As I read the entries on this website I felt like they were talking about my son.

I am taking him off of it to see what happens, but now I'm nervous that his asthma will flare. He's had quite a few asthma episodes since the fall allergy season has started. I suppose he'll need to go for awhile to get everything out of his system to see if the behavior changes, and then I hope to find a new preventative. We have Pulmicort and Xopenex and an inhaler ready!

*UPDATE* Well, it hasn't quite been two weeks since I've taken James off of Singulair and - I am not kidding you - his behavior improved the FIRST day. I want anyone who reads this to know that I am not an "alarmist", I DON'T freak out over everything I read, I do a lot of research (kind of obsessive myself :), so please understand that I am not one to usually write things like this...I mean, I pushed my allergist to give it to him in the first place! There are plenty of kids out there that are fine on Singulair, but some are not. I didn't make the connection to the Singulair since the average three year old is irrational and unpredictable anyway, but I KNEW something wasn't right. It wasn't just tantrums and whatever, his overall personality had done a 180. In the last two weeks my son has returned. He still, of course, has three year old moments, but he is back to the caring, loving, curious, excited, social, happy kid I had last year. One of the worst things we were seeing two weeks ago was bedtime behavior. BAD OCD behaviors - everything in his room had to be PERFECT. The curtains couldn't have a peek of light shining through, there could be nothing on the floor, everything had to be in order. He would obsess about things (creatures) coming into his room, when we would say goodnight and close the door he would scream and cry like someone was stabbing him and was petrified. The FIRST night that we stopped the Singulair he laid his head on his pillow, said goodnight and went to sleep. Please keep an eye out for personality changes in your kids.
*November update* it's been almost two months since we took James off Singulair and we haven't seen ONE BIT of the horrible behavior that we had w/ the Singulair! Normal "three-year-old moments", but no return of the "devil child", no OCD, nighttime freak-outs, violence, or any of it.

could anyone tell me if claritin is the same as singulair or what i could give my child that would help with the allergies/stuffy nose she was on singulair and was taken off

Oh my gosh. I am on this website because I googled "behavior issues with Singulair" Both of my children are on Singulair. One from as young as 5 months old. Both Pulmonologist, allergist and Internal med Ped. insisted that it was a safe drug. They aren't living with it. My 7 year old has taken it consistently for 5 years and recently upped is having behavior, aggression, insomnia and constant reports back from the teacher on his behavior. We had him psychologically evaluated and they found nothing uncommon to his age. All his issues are described in almost everyone of these side effect threads. I am just afraid to take him off and feel the blame if something serious happens. I am calling tomorrow for possible alternatives.

So happy to find this site. I never noticed My son never had an eye tick until last month, ironically we started giving him Singular on a daily basis about the same time. My son just turned two and is has also been waking up screaming 3 times every night. Have others reported this same problem...also he is on Pulmicort too, have you read that it is linked to Glaucoma and Cataracts? Do you think that this could be causing the tick? Please HELP! I want a parent's opinion before bringing this up to the doctor...they are so quick to jump to more drugs it makes me sick! Thank you! Any other children with eye "ticks" like really quick consecutive blinks?

My 12 year old was on Singulair from age 4 to 10. We too thought it was a life saving drug. The doctor then put my youngest son on it for allergy cough etc. That is when all hell broke loose. He immediately had signs of depression, anxiety, anger, nightmares, ocd and facial ticks. We took both boys of this drug and I will never use it again.

I've told every doctor that we visit about this and they have basically said they haven't heard this as a symptom. When I told his immunologist this was a symptom he said that if I'm telling him it's a symptom then they aren't going to dispute it. His lack of surprise led me to believe that this wasn't the first time he heard this. This is the same doctor that put my 12 year old on this drug as part of a study through U of M. (At the time, the drug wasn't available for 4 year old)

I would strongly caution anyone about the use of this drug and I wish I had done more research. My son has been off it for 2 years and still has
lingering effects.

My 5 1/2 year old son began taking 4mg Singulair in the p.m. and an inhaler (asmanex) in the a.m. We were still having trouble controlling the asthma and his Sing dose was raised to 5mg. & within 1 week of the increase he began having terrible facial tics and aggravated behavior (defiant, poor listening, easily frustrated and angered) The tics were in the form of opening and closing his mouth, as if you were trying to clear your clogged ears after a plane flight. This caused him much pain in his jaws and facial muscles, so he would tic and then cry as he was in pain. This ramped up his anxiety and it made the ticking worse. He has been off of all asthma medication (cold turkey) for 5 full days. He has episodes where the tics happen for 10 min -1/2 hr, other times during the day it is one here and one there. He does not want to leave the house to do anything, even his favorite activities. Thank god I found this site (and others like it), as I got some answers and some hope. We went to see my cousin this week who is a neurologist and he never heard of the correlation of Singulair and neurologic side effects like these. He said that (hopefully) the medication side effects will cycle through and resolve the ticking and behavioral changes. If not we are probably looking at a Tic Disorder which is in the Tourettes Family.He put my son on a very low dose of Klonopin to mellow out his anxiety and help reduce the tics, but has only been on it for 1 1/2 days and it usually takes a wk or 2 for full absorption and results.I have since sent him and my pediatrician and allergist links to this site and others. I think that I see some improvement in my son, yesterday I thought he did better and my husband thought it was a worse day, I think we have totally lost our perspective and objectivity on this. If anyone out there has a time frame on when they saw significant recovery and positive changes I would love to hear from you. This is a total nightmare and if it is this drug, someone is going to pay. My prayers go out to all who are going thru this.

My son is almost 5 now and has severe food and inhalant allergies, along with sever asthma. When he was 3 he was hospitalized for 4 days because of his asthma. I have been warned that only 1% of asthmatics will ever be hospitalized, so I've made sure he stays on all his meds. He has been on Singular ever since he was 15 months old. At first it was a God send. Everyday was a constant challenged, fussy, icthy red eyes, constant flow of mucous and wheezing. I would have to pin him down 6 times a day with the inhaler, but when Singular came "poof" it was like magic. He was on Singular when he was hospitalized and is now on 3 meds; Zrytec, Singular and Q-var all given to him everyday. Lately we have had some major issues come up for him. I think I have the next J. D. living with me. NO FOR REAL. My next step is a shrink. You might think I'm mean for saying it, but I don't know how else to describe it. When I was driving he asked for some gum, because I wouldn't let him pick out his own piece, he got out of his car seat and started hitting me over and over again, pulled my hair and tried to "break my arm" as he put it. I had to pull over and I couldn't get him to calm down he kept slapping me in the face and kicking me not only was I embarrassed, but it hurt, I was crying. I have finally come here trying to see if other children, who are on Singular, have had similar episodes. He is a very good boy most of the time and aggression is a hit and miss. I don't know what to do.

i have a son who is 2 years old and suffers from asthma. we have been prescribed the singular 4mg tablet, when i read the possible and common side affects i started wondering if it was really going to benefit him.. now that i have read most of these posts i'm really starting to think it would be best to not try him on them.
if anyone has any helpful advice PLEASE reply back to me

My 8 yr old has been on singulair since May. I never put two and two together until reading these posts. He has been having anxiety at night..crying and looking terrified saying he can't stop the scary thoughts in his head. Tonight I felt so bad for him...because I can't make it go away. I am hoping with tonight being the last night on singulair he will not have such a hard time at night. He also says it's very hard to get to sleep at night. Poor kid. I also know he's a sensitive kid but it seems a bit overboard in the last few months....like getting upset and just not knowing how to handle his emotions so he just shuts down. Please message me if you've had similar experiences. I'm calling his dr. on Monday to figure out some other options if there is any. My son started with a cough in March and finally took him to see the dr. in May and she heard wheezing and started him on singulair and then added zyrtec. I know they control his coughing (wheezing...slight asthma) because if we miss a dose he coughs all day the next day. I'm a bit scared to go off it...but hope it stops the anxiety and moodiness. He had his first asthma attack last week too...and I wasn't prepared as we never have had to use the inhaler...so I didn't have it with us. Anyway, hoping he doesn't get too bad taking him off...and I hope he is able to control the scary thoughts by going off of it too.

My daughter is 5 years old and has been on Singulair for about 2 years now. I was at a loss concerning her behavior for the past 2 years. The anger, aggression, tics in her eyes and legs feeling tingling, unable to express herself, and truly not liking herself and thinking we don't like or love her. All this brought us to take her to therapy. And then all this information regarding side effects of Singulair come out. I brought this to her allergist and he like many others brushed it off. I think it is time the medical community looks very close at this drug concerning side effects with children. How many more parents have to come forward with all the same side effects for these educated doctors to realize there is a hugh psychological and neurological connection with this drug for some children. It has been two days now that my daughter stopped Singulair. Her nose is already starting to drip and her cough is back, but I would much rather deal with these side effects of allergies than watching her go though this mental anguish any longer. I have not seen any changes yet, but it had only been two days.

My 9 1/2 yr old son started Singulair in July 2004 when he was 5 yrs old.Looking back now we realize that he started showing signs immediately. We only gave him Singulair in the fall when he had the most trouble with his asthma. His asthma was under control immediately but was not worth the damage that was done. He complained of pains in his legs that I just thought was growing pains. He would sometimes run a fever with no other symptoms of being sick and then the fever would go away. He would also feel like he always had to go to the bathroom, especially after he went to bed. I gave him Singulair at 7pm before he went to bed. The biggest change we noticed in him was the signs of attention deficit. We first noticed that he kept getting out of his seat at dinner time. No matter how many times we told him to sit down he would sit down and then a little while later he would get right back up. We realized after a while that he wasn't doing it to be defient he just couldn't help himself. I asked his Kindergarten teacher if he had trouble sitting in his seat or with attention but she didn't think he was any worse than any of the other Kindergarten kids. In 1st grade, at the beginning of the year, his teacher said he had trouble keeping his attention but then by January she said he was a different kid. We usually stopped giving him Singulair in December. The same thing happened with his 2nd grade teacher. I question his allergist in the fall of 2nd grade but his allergist said Singulair wasn't the cause for his ADHD symptoms. When his 3rd grade teacher contacted us in Oct 07 with the same complaints I realized that it must be the Singulair. I looked online for Singulair side effects and came across this website. I couldn't believe it. I was so disappointed in myself for not doing it sooner but we took him off Singulair immediately. I called his allergist the next morning and questioned him for a second time and he told me that sometimes parents of kids with ADHD just look for something to blame for their childs behavior. I couldn't believe he said it to me. We made an appointment at Children's Hospital Boston to have him evaluated for ADHD just in case but couldn't get an appointment until Feb 08. When we had him evaluated he had been off Singulair for over 3 months. The neurologist said he did not have ADHD. When I asked him if he thought Singulair could have been to blame for the symptoms he was showing and he said there was "compelling evidence" that showed Singulair does cause ADHD symptoms in some children. We were happy that he did not have ADHD but were so sad that we gave him this medicine for 3 years without realizing what damage it was doing. My biggest fear now is that there may be long term damage. All his symptoms have gone away but sometimes he still seems a little out of it and I don't know if it is just his age or his personality or if it might still be some long term effect from the Singulair. He is such a sweet, loving, caring boy and I hope that I didn't do any long term damage by giving his this horrible medicine. I hope that something will be done soon to get this medicine off the market. My prayers go out to all the families who lost children on this medicine. I can't even imagine the pain you are feeling but I thank you for getting your story out and saving other children! I am thankful that I was able to get informed by this website because God knows my allergist wasn't looking out for my son! His asthma has been under control since being off Singulair and just seems like a happier child over all!
Thank you!

I'm an adult female with severe sinus polyps, adult onset asthma and allergies. Initially Singular seemed to be helping my nasal polyps, when nothing else helped in any way. I made several attempts to use Singular, and proved repeatedly that this medication did, in fact, cause me severe side effects - even when I used a childs dosage. While using an adult rx for Singular, I immediately began experiencing horrific nightmares (which I have never had in my entire life). I also had extreme knife like pains in both ears, which made me feel like I had a severe ear infection, chest pains where it felt like a cinder block was lying on my chest, and migraine like headaches (which I've never had). I stopped the medication after about a week and the nightmares went completely away, but it took me a couple weeks to recover completely because I developed what felt like a respiratory infection and ear infection as soon as I stopped using it. Because Singular seemed to slightly reduce my nasal polyps on my first attempt, my allergist suggested I try using it again - almost a year later. When I first began, I completely forgot about the negative side effect and why I stopped using it in the first place, and just gave it another try. I again experienced the same horrific nightmares, ear pains, but this time got a strange rash/cluster of blisters under both eyelids which my eye doctor confirmed was an allergic reaction to something I was using. Singular was the only medication I had changed. My allergist thought I should give it longer to see if the symptoms went away (because they probably weren't caused by this medication - and were due to something else ???). Fearing going to sleep, I decided to try taking the medication in the morning instead of night, and had my physician reduce my rx to a childs dosage (5mg). The nightmares lessened, and the blisters under my eyelids went down, so I continued using Singular for about a years time. What I didn't realize, was that over this time I was becoming depressed, fatigued, and became easily agitated and short-tempered, which was very different since I was normally a very happy, energetic mom. My nasal breathing seemed to be slightly improved, so I just kept taking the medication - not realizing that it was causing all of the other problems I was experiencing. I became so fatigued and depressed feeling, that all I wanted to do after I got my kids off to school was to sleep until it was time to pick them up in the afternoon. I was also experiencing stomach pains for unknown reasons. I was certainly not myself. I didn't realize that while I was using Singular I had lost complete interest in everything that I normally loved in my life. And please note I'm 45 years old, and I was using a childs dosage. ( I can only imagine what this medication does to a child. )Fortunately for me, I accidentally forgot to refill my prescription for a few days and noticed that my depression started to improve. I decided not to refill my rx and stay off it to see if I continued to improve - and I have. Unfortunately, even though my depression has all but gone away, I'm experiencing symptoms which must be from withdrawal of the medication - and they are just as scary as the side effects were. Now that I'm not taking Singulair any more (and I've made no other medication changes), I have extreme fatigue beyond belief, and ache everywhere. My muscles are in such pain that I'm having difficulty doing things I would normally do. I have extreme weakness in both arms and legs, and my back aches almost constantly. And strangly enough, my asthma and allergies have slightly improved since stopping Singular - I thought for sure my allergies/asthma would worsen when I stopped completely - but they did not. All I can say is - please trust what your body is telling you - even if your physician tells you otherwise, and do not use this medication or any other if you experience adverse side effects to it. I would never give this medication to a child that wasn't old enough to tell me what he/she was experiencing, and would document the childs temperament, ailments if any, and what changed once the medication was started - and discontinue it immediately if even one adverse side effects occurred. One last note - I am still experiencing vision problems, which I feel are due to using this medication. Hopefully, no other permanent damage to my body will result from the Singular that I've already used - and I hope you Singular users will recover completely too from its dangerous side effects. Wishing you the best of health!

I was searching for a site with the side effects of Singulair for my son who is 10 and has been taking Singulair since he was 2. It was a life-saving drug for him and his life has been wonderful since then (as far as asthma goes). He is a very athletic boy who plays every sport he can and he is still a little overweight with cellulite and love handles. I had heard that maybe it might be the Singulair so I decided to check it out. Little did I know about all of these other side effects. He's been taking it for so long that I assumed his depressed personality was just the way he was. He has also had such horrific nightmares and he's convinced he has a ghost in his room that shakes his bed that I was really starting to consider that maybe he might. His brother sleeps in the same room and does not have any of these experiences (also on Singulair). I am SHOCKED! I only read about 20 entries but I'm going to read more. Has anyone had the weight gain problem? Thank you for anything you can share.

Hey to All.
I know that the ALA study got everyone upset and I am happy we all emailed her.We all pretty much got the same response from Heather,defending the study and the integrity of the results.If only this investigation would conclude!
The Merck company contacted our Senator and indicated there was a conclusion and then ,they never got back to her before the weekend.I will have news early in the week.Please everyone just keep on voicing your concerns by reaching out any way you can.Sometimes it seems unbearable and I have to take a break with the communications on this website but,I continue my communication with my local contacts and the FDA.
I would love quick results and everyone would love this to get the publicity this story deserves but,if you look at how far we have come getting attention focused on this drug it is amazing.
This website has been here for years and people have complained and nothing has been accomplished until now.Our system is so broken it will take time to fix it.Drugs get approved everyday and when they are put out for multi use,the population benefit -risk ratio changes and there is little oversight on this matter.
The problem is much bigger than just notification of updated side effects,which indeed is why our son died from this drug.It is reporting adverse events to the FDA and the drug company and following up on your report.We can only fight within the system of the government that is in place at the moment and push for change to take place in there programs.
This is what has take place as of this year,The FDA's new 'Safe Use "iniative(which when it gets further developed will increase our partnerships with physicians as well as patients) and the July 2008 AAM report" Education in Safe and Effective Prescribing Practices" which aims to address the education of the next generation of physicians on how to best use medicines.This may help in notification practices and over prescribing but, we want the drug companies to lose the unprecedented control over the clinical research and and evaluation of there own drugs.What other company in the USA, gets to self regulate.Change will come ,we have asked for accountability by having a signature exchange when new and updated side effects are found.Full disclosure of all reported adverse events to doctors from the company representatives,with signature required upon full understanding of the benefit -risk ratio change. A prescriber should know all the good and the bad about a medicine they have chosen to dispense,if not then they should not be able to dispense it.If we were not knowledgeable about selling mushrooms and we sold the poisonous ones ,because we did not take the time it would take to educate ourselves about them,would we not be legally responsible for our actions.
Accountability is what we are asking for and maybe the candyland doctor prescribing practices would stop.They seem to ,not have a responsibility to their patients and the company has no responsibility to the prescribers,so who is responsible for our safety?
I will keep fighting for real change and all you people must do the same ,make an appointment with your representatives and have them contact our Congress representative of NY,maybe with enough onboard we can get the legislation we need to put a law in place for proper notification practices.Kirsten E. Gillibrand Member of the US House of Representatives 120 Cannon House Office Builing Washington, D.C. 20515
This is how change is made ,if you want to help please go forward and do this and don't stop until they listen.I am always willing to do whatever I can,it is physically exhausting and sometimes I just have to step away but, my daily review of this site has not stopped and my fight will continue.Dave and I sit here and our hearts just break for all but, we need people to push their Representatives they do work for the people just remind them of that.Any one with questions or that wants to communicate via private email just ask for my email address or phone number or leave me yours and a time and I will be sure to contact you,Kate M.

My son has been on Singulair off and on for two years. He goes off in the summertime since his asthma is mostly due to upper respiratory infections. He recently went back on it, maybe three weeks ago. He is 7 years old. Every morning now he wakes up with nightmares. This morning he said that he had a nightmare that all six of his webkinz were killed, except for one. The night before he said a tornado had blow our house away. There have been other nightmares too.

I decided this morning to stop Singulair, then called the allergist. The allergist agreed we should stop it and see what effect would happen. Today during school, the teacher had to call me because he was yelling at other students and was hitting books because he wanted a prize for fund raising. She said he was inconsolable.
During the summer, he was a totally different child -- easy going, laughing a lot. Now he seems stressed out, anxious and depressed.
I also noticed he has begun oversleeping.
Even worse, he was diagnosed with ADHD back in April. All of the surveys filled out by teachers and by me were from when he was on Singulair.

I know that drugs can do this to adults. I was once on a birth control pill that made me so paranoid and neurotic, I had never felt that way before. A different pill was fine and never had that happen again.

Has anyone experienced difficulty swallowing solid foods? My son has been on it for 2-3 years and this issue has just developed. Not sure if it has to do with the Singulair or not. He's had an Upper GI and no physical problems show up. He is 11 years old and the allergist says the mood swings are due to his age, not the medicine. He has been really down and cries at the strangest things.

I have a 2 1/2 year old daughter who was put on Singular about 3 months ago. About a week after taking it she began to break out in hives. Has anyone else observed this in their child? I took her to an allergist who ran all kinds of tests and they said that she was allergic to nothing. I am taking her off of it to see if the hives go away. She is also very moody, cries all the time, is very aggressive. She was never like that until she began taking this drug. Of course, the allergist said it was not Singular, and for me to continue giving it to her.

Hi everyone, I just want to say thank you for all who shared on this site. I am a 47 year old woman. I have spent several hours reading posts last night and today, and discontinued my Singulair last night. I have been taking it for approximately 4-5 years for mild asthma. Since then my health has gotten worse and deteriorated rapidly in the past year. I have had chronic chest congestion leading to frequent infections. Have had pneumonia three times in the last three years and frequent bronchitis. In the last eight months I have been on antibiotics more often than not, along with Singulair and Advair and frequent rounds of prednisone. Still I continued to worsen. I have had a rash on both legs since March which clears up with a shot of prednisone, but comes back within a few weeks. I've been going to bed nights by 7:30 and still find it hard to get up and go to work. Energy levels would vary, but some days I literally felt as if I could not keep putting one foot in front of the other. I have always been the quiet, serious type and prone to depression, but this past year it has been getting progressively worse. I have become very antisocial and even missed my son's wedding because I was so stressed out about it. I have also had alarming hair loss and just feel that my body is in a very depleted state.
My doctor, an allergist, ran a number of tests, but could find nothing. He finally referred me to a specialist at a University. He did a bronchoscopy and tested for tuberculosis and sarcoidosis because I had very similar symptoms to both of those diseases. They were both negative, but they found a rare form of bacteria in my lungs that doesn't respond well to medication. They felt that it should run its course eventually. I'm sure all of the immune suppressing drugs I have been on have made it difficult to recover from this. Aside from a two week prescription for a form of sulfa which they felt the bacteria may respond to, I am off all other drugs. For congestion they have prescribed a therapy vest instead of medication. I am very anxious to see if being free of Singulair and Advair helps me to recover more quickly. Already on day one I feel a better outlook on life and even went on a shopping trip with my mother today :-) I can't say at this time what role Singulair has played in all of this, but am anticipating an improvement after reading all of your posts. Thank you.

My 10 year old son has taken Singulair on and off since he was 5 years old and has been on it for the past 3.5 years. My son at an early age was affected by a bad marriage and then the divorce when he was 5 yrs old. So we always suspected that his behavior issues were caused by this and I had done everything I possibly could to give them the help he needed to get over and through his issues. He was held back his first year of Kindergarden and during his second year midstream he was placed in a special class for behavioral problem children. Nothing ever seemed to help him, everytime we would see some progress and encouragement we were always blind sighted by a behavior that was always worse. Two steps forward and them 5 steps backwards. I always knew that his problems would never get better overnight so I just kept on going. He was diagnosed with ADHD but because he has some ticking issues I had to put him on Strattera which was did not do a thing for him. I always described him as my Dr. Jeckyll/ Mr. Hyde child. He could be really good and sit still and behave but I think he had to try really hard to do so. He eventually was always overpower by the impulse to show negative behaviors. Defiant, extremely impulsive, always negative and completely miserable all the time. He also went through phases of compulsions. There was always a compulsion of the month- germs, bathroom habits, noises, repetitive words. He hated school and always complained of a stomach ache which i thought he was always faking to get out of school. He had confrontations in school everyday for most of the day. I often thought some of this was because of being tired all the time. We had battled over bedtime every single night. He was terrified to go to bed alone, I tried everything to get him to sleep alone. I wore myself out falling asleep next to him, I would then go to my own bed only to be up with him half the night going back and forth. I gave in many a night and slept with him just so we could get a good nights sleep. At age 8.5 I finally got him to go to sleep alone but the lights haf to be on and he has to know that I am still awake before he will fall asleep. He would always say he didn't want to go to sleep because when he does he has bad thoughts about me and people that he loves. He always had an extremely hard time excepting the word "no"- he would flip out and hit his head with whatever was handy, throw things, break things, scream holler etc. It would take hours to get over it. When he did he would be very remorseful and lovable. He was always in turmoil. Finally in February of this year, this graduated to a new level where he would want to just kill himself and would actually go and pull a knife out of the drawer and just shake with anger as he held the knife to his throat. I was terrified although i really didn't think he was going to harm himself he just wanted to scare me. Then at the end of March when i first heard the news about the possible side effects of Singulair, I had only heard about the suicide effect. Oh great just what I needed was this medicine causing him to do that. The doctor was thinking about taking him off if this summer because he wanted to see if he out grew his seasonal allergies so I took him off immediately. Well I had no idea about the other side effects until my son turned into a completely different kid. School noticed a huge difference in him! His grades went up, his is able to control his behavior, he is happy he is NORMAL. I never suspected this drug as the culprit due to the timing of taking it. Our lives have changed completely. When i first found this site, it seemed as though some of the parents were writing about my child. It is amazing. My son still has some old habits to break but overall he is a wonderful and normal 10 year old boy. He did not outgrow his seasonal allergies but Allegra seems to help in through it. I get so angry- his whole early childhood was ruined by this medicine. He is a labled kid in our school system. This whole experience has opened up my eyes. Thank you for letting me share my story.

My 54-year-old fit, social, successful husband was put on Singulair in January for newly diagnosed asthma. He developed a depression with anxiety, irrational fears, avoidance, mood swings and even one episode of suicidal thoughts out of nowhere. He saw a psychiatrist and a therapist, tried medications, yoga, a vacation, meditation, breathing exercises - everything! But he kept getting worse.

The day he was throwing patio furniture then sobbing uncontrollably was the day he realized he couldn't work in his condition. He negotiated a 60-day leave without pay. Even that didn't help. It was crazy. How could a man who managed hundreds of employees and a major health service system for 20 years suddenly be so paralyzed with fear that he couldn't walk down a beach or go into a Walgreen’s?

We found this site May 26th. He stopped the Singulair immediately. It has been 10 days and he is already 80-90% back to normal. Thank God.

Partly I am writing because it is so hard to read of parents' guilt that they "should have known" etc. Look, unlike a child, my husband is mature and very verbal; he is also a psychiatrist (!) with a capacity for self-examination and a language to describe his inner experience. And me, I'm a psychologist (!) trained in understanding people and I know him very well. And yet with all that training and skill and consultation and treatment, WE STILL COULDN’T FIGURE THIS OUT! So please, don't make yourself feel any worse with guilt. This is awful and tragic enough already.

I would add that the onset of mood and behavioral problems is so insidious that it is hard to connect the problems to the Singulair. Also, I suspect that children and adolescents are at greater risk because of their immature emotional developmental level. An adult l suspect may need some genetic or personal predisposition to mood disturbance, or stress, or both, to trigger these side effects. My husband had a depression episode 30 years ago and had recent traumas that certainly could have triggered the depression. But how treatment resistant that depression was, and those strange paralyzing fears and extreme anxiety – all that I blame squarely on the Singulair.

I have made a report to the FDA. I urge you to do the same.

My 17 year old daughter started Singulair last July for Asthma. She is brilliant and scored in the 99% on the ACT college entrance exam. She won 3 scholarships totaling over 60,000 and earned 27 college AP credits while still in high school, volunteering for the Red Cross, singing in choirs, and playing the lead in her high school musical and 3 plays. She was funny, sweet, and had many friends.
She left for college 3 weeks after starting the medication and saying she was breathing better. Her grades were terrible, even though I was able to check to see she went to class every session, as posted online. She became very depressed, withdrawn, staying in her dorm room. She was sleeping up to 20 hours straight without waking up. She didn't call her friends when she came home and only wanted to sleep. She was like a different person. She was so aggressive that she tried to run out in the middle of the night and attacked me when I tried to block her way, to the point I had to call the police. They diagnosed her with new onset major depression and ADD. They started her on Zoloft for 2 months and she got much worse and was removed from Zoloft as a result. She said she was too tired to stay awake even in class. We had a sleep study done for Narcolepsy and it was negative. Until reading these posts, I didn't connect the Singular. Everything I am reading is so familiar, it makes me feel ill. I can't believe I didn't know, I am a nurse. The guilt is horrible. I hope to get my daughter back, but she lost all her scholarships and only managed to pass 16 hours in one entire year of college. I can't afford to send her back without the money she lost. They even put her on a one time only probationary period to ever get Federal or State Financial aids and loans again. Singular had to be to blame. I am simply thankful my daughter is still here, she was very suicidal. My heart breaks for those of you that lost your children to the side effects of the drug. We have to get the word out by each filing a complaint to the FDA, and filling out adverse event forms.
Please don't let Merck get away with this. We need to act, even if your child was one of the lucky ones and is back to normal now.

My daughter, just turned 3, was put on Singulair this past January for allergies. She had chronic runny nose, sinusitis, coughing, often leading to infections. The allergist put her on Singulair combined with Hydroxyzine every night. Now that I have read these postings, I recall that we had one really disturbing episode with her, although I can't now recall exactly how long after starting the drugs. Like some others have described, she woke in the night, seemingly terrified and at the same time in extreme pain. We could not find any way to soothe her or relieve her pain - she simply fought and flipped around, alternately reaching for us and kicking us away while screaming and crying and writhing on the bed. After a time, maybe half an hour, it seemed to just pass and she finally went back to sleep. But then we endured a couple of months of repeated wakings at night, sometimes when she was restless for an hour or more, sometimes upset. She might wake 3, 4, or 5 times in one night.

Lately I have become concerned about her increasingly aggressive behavior towards us, but recently towards others. And I am also very concerned about her physical growth. She is 41" and over 40 pounds and turned 3 a week ago. I am now buying her size 5T clothes. I have finally gotten proactive (why did I wait??!) and consulted with her ped., who has agreed that we should screen her for anything we can. My daughter has been diagnosed with developmental delays (pre-Singulair) and is in a preschool with similar kids. We have been dealing with behavior issues for the last year, and I am astounded that an allergist would put her on Singulair with the current controversy about it's side effects. I took her off it immediately as soon as I found out there were negative reports - thankfully our experience has not been as extreme as many others. But I feel ill at what could have happened! I am now praying that she has not suffered any irreversible damage...

Bless all of you in your struggles.

I was put on singulair in Feb of this year but the 5mg and it seemed to be helping. I went and saw an allergist and he put me on 10mg of singulair and i have been on it for 11 days. And I have had, stomacher pain, muscle pain and weakness and I feel out of it, I am also depressed and ill tempered. I went to my doctor today and she told me not to take it anymore and she sent me to a new allergist. This stuff needs to go.

I just viewed a commercial for Singulair now marketing directly to children. Has anyone seen it? They're promoting cherry flavored chewables and a cute little kitten in the background. The side effects so many of us have experienced with our children are still not mentioned instead they've done the exact opposite. With this drug under investigation(Dr. Sarah Sellers has already sent a personal email from the FDA) this is immoral! What can we do to stop any more children from being injured? Merck has no ethics, NONE!

I am posting this as a new post. I am not against Singulair. I am against withholding negative side effects from the patients. I am against promoting that Singulair is safe and effective for everybody on the planet.

My entire family is health care. My father was a surgeon. I worked for a pharmaceutical company. Pharmaceutical companies are supposed to ethically invent drugs and inform everybody about the safe and effective way to use those drugs. Pharmacists are supposed to police the prescriptions and dispense the correct dosage. Then pharmacists are supposed to be aware of side effects and drugs interactions. When necessary, pharmacist are supposed to intervene to prevent a mis- communication from turning into a disaster. Doctors are supposed to review the recommendations of pharmaceutical companies (who are policed by the FDA) in order to determine if their diagnosis matches the profile of drugs known to be therapies for certain symptoms. I, personally, am madder than hell at Merck. Singulair could really be a good therapy when it is needed. It could correct some bad stuff that happens short term. Why does Merck's need to make every drug a major block buster money maker ruin the market for Singulair?

My son age 3 was diagnosed with asthma about a year ago. Since then he has been sick constantly. Most recently his doctor has prescribed Singulair. He is aggressively pushing it on us. I stated my concerns to him, and he said there is nothing wrong with the drug.. he gets all the news letters.. and all the things I listed was the first time he heard anything.. I asked for his to refer us to a specialist and he wont.. I cant find anyone for a second opinion..My son needs medicine- at night i cant leave his side cause of his breathing.. The doctor wont suggest any alternate and I am stuck. I keep reading about all the people who are not taking singulair anymore- what what are they taking? I am completely lost here!

I'm a 30 year old male, and I've been on Singulair for eight years now to treat chronic asthma. Shortly after I started, there was a noticeable change in my mood and behavior. What I noticed included sadness, thoughts of death, anxiety, and fatigue. I knew that there was something wrong, but just chalked it up to changing life experiences. I was always heavily involved in organized sports (little league through college), but abruptly stopped after college. I thought that the moodiness (or depression) came on because I wasn't as active anymore. Correlation maybe? I don't know. But I do suspect that Singulair is the culprit. I would like to get off for a while, but I literally cannot breathe without it. Does anyone know of any comparable alternatives to Singulair that won't bring on these type of side effects? Thanks all for sharing. Blessings!

Chris, truthfully your posts were a waste of your time. The majority of the people here who have actual instances that they can account for. For you to dismiss that is ignorance in it's true form. QUESTION? what drug company do you work for? As you have a valid point there are side effects with any medication prescription/over the counter/herbal, whatever organic/inorganic source it may be. As a medical professional I HAVE SEEN THESE SIDE EFFECTS FIRST HAND! I also have a friend who works for the FDA who has informed me of many developments that unfortunately because it is under investigation I can not post. I also have had a first hand experience with this drug with a young child. I understand some parent/people may also be ignorant and be quick to blame the singulair without ruling out any other possibilities. However the fact of the matter exists here. So again for you to dismiss what the majority of the people here are trying to do is quite frankly rude. To go through hell and back with my four year old innocent child, to take him off the med and now everything is fine. Coincidence... I think not. He was evaluated by psychiatrist, neurologist, his pediatrician-who consulted with 3 others, and an allergist and all come to the same conclusion. I will advocate until every parent/patient knows the risks. It is my responsibility as a parent. If I can prevent another child from going through this, even just one then I accomplished something. So again I ask you to be sensitive here and not try to make those of us who have valid concerns feel as if it may be otherwise. Do your research first!

I have come to the conclusion that our pediatricians, allergists and various other doctors, have been brainwashed by the drug reps,possibly even bribed. My friend took her son off of Singulair almost a month ago when I told her about all of this. He already suffers from a learning disability, but she feels that his ability has improved along with his disposition and complaints of various aches and pains. She took him for his usual appointment at his allergist and told him what she had done and why and he literally YELLED at her, calling her a fool and demanded that she put him back on it. She stood her ground and refused and now is under the impression that her son will be dismissed as a patient from that practice. That won't be a problem. From what I read and what I hear, a lot of doctors are dismissing the whole deal. They can't be bothered with finding out for themselves, what the truth really is. No, they might miss out on the "perks" from the drug reps, like free samples of the deadly drug, or free pens, or a chance at a vacation in the Bahamas, and the list goes on. The drug reps are a hazard. They lack education on the drugs that they are "dealing", and if they HAVE been educated and are still promoting it,
they are no better than the crack dealers in the alley.

After visiting this web site everyday for the past four weeks, I feel the need to share my daughter's (and my families') experience with singulair. My 8 year old daughter was put on singulair aprx. 2 years ago in addition to zyrtec to treat her allergies. Shortly after starting the drug, she developed stomach pain. After a few weeks of chronic pain, I pursued help from our pediatrician. After visits to two different pediatric GI doctors, an allergist (to test for food allergies), and an orthopedic surgeon ( because of sudden leg pain), the results were inconclusive. During this time my daughter also became very sad, angry and fatigued. She also completely lost her appetite and refused to eat much of the time. I attributed all of these symptoms to her stomach pain . In addition, she developed difficult sleep patterns and would often wake-up exhausted in the morning. Over time she also began to have more and more "melt-downs", breaking into crying spells over the smallest provocation or challenge. I recently contacted my daughters pediatrician to discuss what other testing or direction we could take to help my daughter. In the interim of making that contact, a friend told me about this web site. As I read page after page of other parent's experiences, I was in tears. I felt as if I was reading about my own family for the past two years. I say "family" because when one child is living through this kind trauma, everyone in the family is negatively affected in some way. My husband and I felt completely frustrated and unable to help our daughter. Our older children began to resent the great amount of time and energy I spent on behalf of our daughter. My younger daughter who had always looked up to and loved her older sister was sad and confused by her sister's anger and impatience.On March 29th I took my daughter off singulair. Unbelievable. Within 2 days, my daughter's appetite returned. On the second day, she came home from school and requested a corn dog and then some ice cream. She suddenly wanted to eat breakfast again. She started smiling and laughing again. She has suddenly become capable and responsible for doing her homework and chores. She is going to sleep more quickly and waking up happy. The best part is having our daughter back...the sweet, wonderful, happy six year old who I feel like I lost for two years of her life! As a side note-the return call I got from my pediatrician was that he wanted my daughter to see a psychiatrist. That's how close we were to taking another (completely unnecessary) path to helping my daughter. I also recently spoke with my daughter's allergist about our experience. At first he was somewhat dismissive. I asked him to listen to me parent, to parent for just a moment. He seemed to soften and said he would take a second look at singulair and its side effects. I encourage every parent who's child has been so adversely affected by this drug to be proactive. First, please contact the FDA to report your experience. Second, talk to your children's physicians and share, with confidence your experience. Third, share this web site or a similar one with everyone you know. I have been astounded how many children are on singulair just within my own small circle (school, church and play group). I really believe one voice can make a difference. I have to believe that for the sake of all the children still suffering.

I am a 47 year old male who took 3 days of 10mg singulair ending April the 16th. On the 4th day, I was walking around in a national chain store and started getting severe numbness and tingling in my arms and legs.
According to the info. pamphlet that comes with the drug, this can be a serious adverse reaction.
About 13 days later, I still get episodes of tingling and numbness in different areas of my arms and legs, and now, some areas on my face. My family doctor says there is nothing to be done about it, and my allergist says I may need to see a neurologist. I think the doctors need to go see a neurologist and have their heads examined for giving us this garbage to take in the first place!
Never had any of these problems until a took singulair! Hope these side effects aren't permanent!
Good Luck to you all, and may all of us get healthy again real soon!

My son has been on Singulair now 5 years and I am in the middle of fighting to get him off. My son is now 7 years old and has been diagnosed with allergies (no test have been done which I find very odd), which leads to a case of mild asthma. This past weekend his mother forgot his Singular on Friday so I could not give him any till the next day, where we met at his soccer game. Saturday night I gave him his usual pill and thankfully due to his exhaustion from playing out side all day he went to sleep in 10 min. vs 3 hrs later which is the norm since Singulair seems to jack him up.
He also has red puffiness under his eyes - most likely allergies.
Seems depressed - just driving down the road and I look at him in the rear view mirror and he just sits and stares into space. When I ask what's wrong he either says nothing or I am tired.
He will try to tell a story or think for himself and just stops mid sentence and says " never mind I am just confused"
He will be having fun one moment and just starts crying or gets depressed.
He was throwing a ball in the house (yes I know) and accidentally knocked a glass over breaking it - he went running to his room, crawled under his bed and sobbed profusely for over 30 min.
He has a hard time doing / focusing on homework - becomes bored very easily.
Does not want to go outside. I will take him to allot of cultural events/ hands on or participation events - he will not try anything. He is unsure and will not come out of his box so to speak.
I spoke with his doctor who was reluctant to take him off, but then agreed that if it was OK with the ex, to take him off for a week to see what happens.
The fun part: My ex is convinced that since he has been on Singulair for 5 years he is fine and does not need to come off it.

1.) Son is diagnosed with mild asthma or allergy induced asthma.
He has never had an allergy test done and has not had a lung function test in over a year.

2.) It is documented that our son has four outbreaks a year. (sounds like the changing of the seasons) but is given Singulair all year round and the dosage has also been increased.

3.) Since the court order, ordered my ex to enroll our son in sports (she would not let him play anything) he does not wheeze or cough uncontrollably.

4.) Since I had to battle to get our son on my insurance I have cut her control issues off a little, but she is refusing to take him off Singular just for a week to see how he reacts. Although I do agree that he should have some form of allergies medicine.

5.) When I found out about the side effects of Singulair, I also found that his doctor was getting ready to add two other allergy medicines to his portfolio - totaling 3 different meds.

I see our sons behavior getting worse and I watch him turn into something he is not and with a controlling individual not believing anything about the side effects it looks like I will have to rely on the medical system to prove my point. I do believe he needs to be accurately tested for allergies and given a regularly lung function test but most of all since he is now on my insurance, a second opinion and a 3rd to narrow down what the situation is and an alternative medical procedure that is fit for the symptoms.

My 5 year old son was taking Singulair for about 2 years when I came upon this site. I immediately called his allergist and got no answers, so I decided to take him off of it. Within 24 hours I noticed a big difference. He use to not sleep. He would be up all night. he uncontrollable outbursts at school, and home stopped. He is now the sweet boy I remember. I really think he was over medicated. He takes Zyrtec in th morning and was taking Singulair at night. I am appalled at the fact that doctors are over medicating our children.

Thank you for this site. I now can love and hug my child agan.

My 13 yr old daughter was put on Singulair along with Asmanex and Clarinex for her asthma about 6 weeks ago. Everything seemed to be going very well at first and her symptoms were starting to get controlled. I started noticing after about 3 to 4 weeks that her temper and attitude were getting much worse. Anyone with children this age knows what I mean but this was like a 180 degree turn for her. Her actions were becoming totally out of character. Before I knew it she would cry and get highly upset over the least little thing. Week 5 came around and things totally bottomed out. She came home from school and WAS NOT HERSELF. Made comments about how she hated her life and it was not worth living. Later that evening we had a big argument because I was telling her nothing was worth saying that. She went totally out of control and I had to physically restrain her to calm her down. It appeared everything was better so she went to her room. I went down to check on her and she calmly told me that she had taken advil and tylenol pm and things would be better for her forever now. We went to the ER where they made us wait for at least an hour, then finally took her back. She had to drink two cups of charcoal and was poked and prodded repeatedly. They did a catheter to get a urine sample. She was very cooperative but also was in a complete daze so who knows. The poor child couldn't even lift her head up when she started the vomiting to get rid of the drugs. It was very upsetting and sad. Her heart rate and blood pressure went very low and I really thought in the back of my mind that this was it. Finally, after several hours she started coming out of it and they sent us home. The next evening when she was starting to really come around she proceeded to tell me how she had been seeing a man walking around in her bedroom at night and she was afraid to go down there. Breaking down and crying telling me about all of the horrible nightmares she had been having recently and didn't know why. I thought what am I dealing with here? This just isn't her. Three days ago I heard about singulair in the news and looked it up on the internet. OH MY GOD THIS SOUNDED LIKE US!!!!! I immediately had her stop taking it and the next day phoned her asthma specialist who agreed she should stop now. We are going to watch her for two weeks and see if any symptoms return and then decide if she needs something else or will be fine on just the Asmanex. As a side note, she also mentioned being unable to concentrate in school (unable to do even the simplest math problems) and that her brain felt confused or like something was missing. She said this had been bothering her for several weeks. I know it was this drug. They really need to take this off the market NOW and stop flirting with disaster. The only reason I posted this was to let others know they are not alone.

Hi.

I was put on Singulair toward the end of February. At the beginning of March I started getting hives all over my body and becoming very itchy for no reason at all. The allergist said it couldn't have been from the medicine. The frequency of the hives/itchiness have slowed, but I still get them. I was also getting a little dizzy when I'd put my hed back or lay down, but I knew that was one of the side effect. But, the past several days, I've been getting very dizzy when I walk. I'm worried this is from the Singulair -- nothing else has changed. Could these effects show up after a month? My allergist doesn't seem too concerned, but I am.

I wrote an earlier post but I am now reading alot of your posts where you say your child experienced FEAR on Singulair. That is so interesting. When my son was on it for around 3 years he would never sleep alone in his own bed and he would have episodes every night that would last up to 3 hours at bed time because I would try to get him to sleep in his own bed, even at 8 years old. I thought he was possessed!!!! He would scream and fight me and I would literally have to hold him down to get him to stay in bed. It was horrible. I'm not sure how a hullicination would be described but maybe that was part of it. All I know is that he turned into a totally different child. It was something out of a horror movie. I eventually gave up and let him sleep in our bed cause it was exhausting. He would just make blood curdling screams and the terror in his eyes was horrific. Then the next morning he would be fine like nothing had ever happened.
Now that he is off of Singulair he will sleep in his own bed with the light off all night. It was an amazing turn around. He also told me he's not scarred anymore.. Who knew????? Has anyone else experienced anything like that with their child????

Oh my gosh, I am just shocked after reading these posts. I am taking my son off of Singulair immediatedly!!!! I knew I wasn't crazy!! My son was on Singulair for over 2 years and it was awful. He was so hyper and uncontrollable. He couldn't control his temper. He had headaches everyday. He was put on it due to severe allergies and asthma. He is on other medications as well as allergy shots. I kept telling the doctor that I think the singulair was causing his bad behavior problems. He was just so hard to handle. He couldn't sit still for anything. The teacher couldn't get him to sit still in his chair. It just wasn't normal behavior for him. The teacher even thought he had ADD!! I didn't accept that however. The doctor just thought I was crazy and told me that Singulair wouldn't cause those symptoms. She said it actually would work opposit that and cause him to be sleepy. Well I took him off of it anyways and he did get pretty sick. His asthma acted up ect. But he eventually felt better and his behavior improved drastically. He wasn't so hyper and he could actually sleep at night and wasn't so scared at night. Just within the last week he has been pretty sick due to allergy season, his asthma has been bad and the doctor told me to put him back on the Singulair. So I did he has been on it for four days now and he is HORRIBLE.. It was an instant change. My husband and I can't control him and he can't sleep at night and has headaches every day. I am so glad I found this sight. I am taking him off immediately.
Thank you all so much for your comments. This medicine should be outlawed. I don't care what the doctors say. By the way my son is 9 years old. I certainly had no idea that it has caused suicide. I am so sorry to you all that have experienced such horrible things. Come to think of it my son used to say he hated himself all of the time when he was on this medicine.
God Bless You All

Previously posted 8 year old son w/ suicidal ideation and depression...I'm seeing comments about "inattentive." I've been saying my son is ADD for years....How many of you saw this possible side effect? Off of Singulair for 14 days now....behavior unbelievably improved.
