Singulair and zyrtec

It has been interesting for me to read this posts. I have been wondering about the long term side affects to singulair- mostly because my 11 year old has been on Singulair for several years now. We spent many of nights in the ER for asthma when he was little and no Dr. did testing. When he was 5 his pediatrician tested him for allergies and put him on Singulair. We have had a great experience with it. I find it interesting that many of the health issues on here- joint pains, bouts of depression, weight gain...I personally experience all of them and i am not on any medication. My 11 year old does not experience any of the mentioned side affects. I wanted to find out long term side affects for my own personal knowledge. Prior to Singulair, he was on Zyrtec which was not a good fit.

My 10 yr old son has been on this medication for 3 months - it helped his symptoms right away. Just in the past week we had a couple days without it when we ran out. He started back up again and has had bad nightmares twice this week and told me that he doesn't sleep well at night. My question is - are their other drugs out there that work as well as this one that do NOT have these side affects? Zyrtec just made him tired.

I have been taking singulair for about a year and a half. Honestly I have had no side effects. It works great for me. I have tried to just take my zyrtec for my allergies without the singulair. I notice that if I don't take the singulair I feel shortness of breath and have to use my inhaler. When I combine singulair with my zyrtec I don't even need my inhaler at all. I was reading some of the experiences from other people, I think maybe children shouldn't take singulair at all.

My allergies caused nearly constant painful sinus pressure, drippy nose (I should have bought stock in Kleenex to profit from my box-a-day use), asthma, getting gradually worse all the time--it was as though I'd had the flu for 10 years (I'm 54). I was taking Claritin in the morning and Zyrtec at night, which only toned down the most severe symptoms. I was on Prilosec as well, as one doctor though acid-reflux might exacerbate the asthma. My family and I are avid hikers, but I haven't been able to breathe well enough to join them for years, even with daily Ventolin and Flovent. I've only been taking Singulair for two weeks, but it has made all the difference. I feel "normal" instead of sick for the first time in a long time. So, for me, it does work. But my stomach's been killing me--like a bleeding ulcer (which I had 25 years ago). I'm hoping that will subside or going back on Prilosec (expensive!) will counteract it. I've also had the weirdest dreams--very vivid and disturbing. Because I did research online before taking Singulair (Doctor uttered not one syllable about side effects), I recognize the dreams are from the Singulair. Because I understand what is causing them, I can easily set them aside when I wake up. I think anyone who's had mental or emotion problems could be sent over the edge by the dreams unless they had a clear understanding and acceptance that the allergy drug caused them. I would be easy to think something was wrong with you to dream such bizarre, violent stuff. (I'd give examples, but I've truly trained myself to forget all about the dreams as soon as I wake us, so I don't remember the dream events now.) I'm quite concerned about children taking this drug. Maybe not everyone has this disturbing-dream side effect, but how could you explain them away to a four-year old? How would you even know if a younger child was having them? Even children old enough to comprehend shouldn't be subjected to horrific mental images, like the 16 year old above. A tip for people who Singulair helps, but they have the weird dreams--try Melatonin (over-the-counter supplement) at bedtime. I've used it to help me sleep in the past when life events kept my mind too active to sleep for several days at a time. Unlike sleeping pills, it doesn't make your tired the next day, you can wake up easily, and it's not habit-forming--it just lets you drift off on days you otherwise can't. Since I'm concerned about the long-term effects of anything taken frequently, I don't take Melatonin very often, but I did try it after the fourth day of Singulair dreams. I had no memory of weird dreams when I woke up, so it seemed to work, and I didn't remember dreaming the next night either. I only tried it that one day because, as I said, I've trained myself to not be bothered by the dreams.

My 3-year old daughter just took her first and last Singulair today. Within 3 hours: crazy mood swings for no reason, uncontrolled anger, bad dreams during her nap time. I didn't recognize her. She's been on Zyrtec for 2 weeks and showed improvement with her allergies and no side effects, but for some reason I let the doctor talk me into trying Singular today. I just threw the Singular in the garbage. Back to Zyrtec tomorrow.

i am 41 and i had been taking Singulair off and on for a few years. i had noticed that something was different about me but never related it to the medication. i always had a sinus infection every year, i stated having headaches and really depressed and didn't understand why. i stopped taking the medication and went and got me some Zyrtec and i have been doing just fine.

My eldest son was diagnosed as a Severe Asthmatic at the age of 3. He was put on Flovent 110, 5mg of Zyrtec and Singulair. I cried thinking about my little guy having to be on daily meds for who knows how long. I decided that I would just try the Zyrtec and Flovent 110, it worked wonderfully. When my eldest was 4, my other son, 2, was put on Flovent 44. Never gave them to my youngest because I knew it was not asthma. I ended up lowering my eldest's dose to the 44 and giving him 1 puff a day with the Zyrtec, he is now 7 and is still under control. As for my younger son, he was not asthmatic, he had sleep apnea, had his tonsils and adenoids removed and is now perfect. Just be careful with these doctors, they seem to diagnose these little ones too quickly......most of the time they are not even right. My eldest went through many many doctors before he was finally diagnosed in the ER and sent to peds for 2 weeks. My youngest went through many doctors too, none would do anything, I had so many excuses as to why my son was such a heavy breather and why he had difficulty swallowing and sleeping. Sorry guys, I ran off here, just want you guys to know that all that are diagnosed with asthma do not necessarily have asthma and I believe way too many drugs are prescribed for these little ones.

My son was on singulair for most of his infancy (11 mos- 22 mos old) we took him off of it when I started staying home with him. He was in daycare and was having breathing issues. We would give him the singulair and Zyrtec every morning. He became a very despondent baby. He would spend the ENTIRE day in the rocking chair at the daycare. After months and months of the teachers telling me this we decided it was best I stay home with him. He came off of the singulair and things got so much better for a while, he began to interact with us and others, not fearful anymore, and slept through the night. However other things have grown to be worse, as he has been developing...every day he seems more difficult to deal with. Now, 5, he is angry, fits of tantrums and rage, can't cope with his emotions, he actually kicked me today during one of these fits. He has been peeing in his room when he is sent there because he has been punished for one of these outbursts. What are the long term after effects of Singlair? Has anyone had this experience? Could the singulair have been given to him too early and now caused some sort of permanent nero or psychiatric condition? PLEASE ADVISE!!!! This Mom is really frightened.

My name is Katie, I am 31 years old. I have been suffering with what doctors call Chronic Idiopathic urticaria for 16 years now. I was prescribed Zyrtec 14 years ago and remained hive free until I had my first son. After a complicated pregnancy and emergency delivery the hives returned full force. The doctor prescribed Singulair in addition to the Zyrtec.

The hives went away; however, I have so many other problems now. I have been seeing a specialist thinking I have lupus or some other disorder, but all my tests are normal. It wasn't until I had my singulair refilled yesterday that I realized instead of symptoms, what I am experiencing may be side effects.

-- I have gained 60 lbs.
-- I have horrible headaches almost daily
-- I am so tired that when I am not working it is impossible to even make myself leave the house
-- I have taken myself to the hospital 3 times thinking I was having a heart attack and told I suffer from acid reflux
-- I have so much pain in my legs/feet/back that I can hardly walk
-- My hands and feet like to go numb for no apparent reason
-- I am always anxious & moody.
-- Can't sleep
-- Clearly I am not myself. Lately, I have felt the quality of life I am leading is horrible.

Wouldn't it be something that I have spent all this time & money trying to figure out what else is wrong with me when it is the medicine I thought was keeping me well really making me sick. Why do the finest doctors not realize when your symptoms are actually side effects?

I am pretty out raged at this point. I would take myself off this medication today if only I knew how to control the edema.

I am a 36 year old white male - generally good health. Could use to lose a few pounds but not overweight. I've been taking Singulair for a little over a year and since then (I also take Zyrtec - over the counter and Nasonex) all are for allergies. I since developed acid reflux - went to my pharmacist and she said that most people with this mix of allergy drugs form acid reflux. Anyhow, I am generally a moody person-have always been - too intense and most of the time I am not a go with the flow person-since I've been taking Singulair my mood swings amplified horrifically - I blow up at my wife over stupid assanine stuff - after reading these posts..today is the last time I am going to take Singulair. Wish me luck. I hope the mood swings decrease.

My daughter is a 4 year old child started on Singulair after she was unable to tolerate Zyrtec. For the first few days her allergies seemed better and we were encouraged by her improved allergy symptoms (allergies to poplar trees, grass, and lambs weed manifest as headaches, itching (usually of the extremities), and stomach aches). However, after 2 days her behavior became increasingly erratic. She was emotional, tantrum prone, irritable, anxious, and had difficulty sleeping although she appeared and said she was exhausted/tired. After several weeks on Singulair, we stopped the medication to determine if it was causing the behavioral and sleep problems. The symptoms stopped after discontinuing Singulair and she went back to her usual happy, well behaved self. After being off of it for several weeks we decided to try it again due to her allergies flaring up and wanting to be sure it was the Singulair causing the behavioral problems (because for all of its negatives, the greatest positive about Singulair is that it definitely helps her allergy symptoms). Unfortunately, the irritability, anxiousness, tiredness, tantrums and insomnia returned. We tried giving it to her at different times during the day but the symptoms were still present (although she slept a little better when we gave it to her in the morning). We also tried cutting the dose in half and giving it to her around noon. Decreasing the dose did help with the symptoms to some degree, but they were still bad enough to outweigh the benefits of taking the drug. As a nurse, I love Singulair for the relief it provides allergy sufferers...unfortunately for my daughter, the side effects outweigh the benefits. Given the rates of ADD, ADHD, and other behavioral problems diagnosed in children nowadays, I thought it pertinent to report these symptoms present in my daughter that are solely caused taking this medication.

My 4 year old daughter was taking Singulair before bedtime (for asthma) and developed vicious bad dreams. I took her off the Singulair and the bad dreams disappeared. Through web forums I learned that this side effect has occurred in many children. For the past 2 months her asthma has been completely controlled through the use of a nebulizer and inhaler. I found out the Pediatricians and Nurses and our care facility were not even aware of this side effect. Why is such a mind-altering drug being prescribed to children? And why does a medicine that produces bad dreams require it to be taken before bedtime? She was also taking Zyrtec to control allergies. Her doctor mentioned that it could be taken any time of day, so we gave her the Zyrtec in the am and the Singulair in the pm. One morning during allergy season we forgot to give her the Zyrtec in the morning, so we gave it to her at night. Five hours later she was crying hysterically! It took hours to get her to calm down, and this girl is a very happy, social, well-behaved and well-adjusted child. I stopped both medicines the next day and within one week the bad dreams disappeared. So I would also cautious parents about Zyrtec as well.

TO ALL

MY SON LOGAN IS SIX NOW AND JUST FINISHED KINDERGARTEN TODAY.
WHEN HE STARTED KINDERGARTEN HE WAS ON SINGULAIR FOR 4 YEARS. HE HAD ALL TH ADVERSE SIDE EFFECTS. TUMMY ACHES, CONSTIPATED, DIARRHEA, LEG CRAMPS TO POINT OF NOT WANTING TO WALK, BEHAVIOR PROBLEMS, HATED EVERYONE, NIGHTMARES, SEES GHOSTS, CRIED OFTEN.

ANYTHING SOUND FAMILIAR. HIS MOTHER THOUGHT HE HAD ADHD OR ASPERGERS AND PEDIATRICIAN AGREED WITH HER.

SOMEBODY THAT I THINK IS SPECIAL FOR ONE WAY OR ANOTHER KICKED ME IN THE RIGHT DIRECTION TO INVESTIGATE SINGULAIR IN EVERY ASPECT.

FIRST WEEK OF GARTEN I HAD TO HAVE A CONFERENCE WITH COUNSELOR AND THREE TEACHERS AND HIS MOTHER.
I LET THEM TALK AND EXPLAIN THEIR THOUGHTS ABOUT LOGANS PROBLEMS. I THEN DROPPED A BIG PACKET OF PAPERS ON TABLE ABOUT SINGULAIR AND ZYRTEC. THEY WERE VERY VERY SURPRISED THAT I PRODUCED THIS INFO.

THAT DAY HIS MOTHER AGREED TO TAKE HIM OFF SINGULAIR. IT TOOK ABOUT 6 MONTHS FOR LOGANS ADVERSE SIDE EFFECTS TO SUBSIDE. HE NOW ONLY TAKES ZYRTEC AND IS GROWING SO FAST.

SO PROUD OF THE LITTLE TURD!!!!!!!!!!!!!!!!!!!

IM NO DOC BUT HOW DID KIDS AND ADULTS SURVIVE ALLERGIES IN THE OLD DAYS?

GIVE IT TIME LET THEIR IMMUNE SYSTEMS CATCH UP. KIDS DO GET SICK. DO YOUR KIDS A FAVOR AND INVESTIGATE THE DRUGS DOCTORS PRESCRIBE THEM. SOME HELP BUT SOME HURT!!!!!!!!!!!!!!

TAKE CARE AND GOD BLESS ALL!!

My son was on singular about 4 years ago and i thought i noticed irratability, lack of interest and depression, but he was only 4 1/2 at that time and i couldn't tell. It did relieve his allergy symptoms. We took him off at that time. Now, again put him back on it this past year (he is now 9 years old) and i see again a lack of interest, depression, mood swings, irritability and his teacher just told us that as this year has increased he has changed in his school work as well. As of last night we will be taking him off of this medication for good and will continue to manage his seasonal allergies with an emergency inhaler and zyrtec/claritin type meds. He is sluggish on the baseball field and not as alert (he unusually a natural athlete!) and he seems depressed and withdrawn - which is not his personality. I thought maybe because he was getting older he was changing but now I realize it is again the medication. It is okay for a week or two to get through a cold or high allergy week, but long term I will not have him on this any longer and wish that Merck would make the long term effects clearer to the doctors, patients and public in general. We are fortunate that his allergy symptoms are not as severe as other children and we can go lightly on medications.

My 4 year old Son has had diarrhea from about the last 4 weeks... we have started some tests for Celiac disease but today it only occurred to me today that he has been on Singulair for about that time frame... after all the worry and reading these other storied Im even more convinced that it maybe the Singulair..
Im just hoping that someone might read this sometime today or the next couple of days to tell me if when they come off the singulair how long did it take for the diarrhea to pass. My son had is last tablet 2 nights ago ( so he has only been off it so far for one night. But he still has the diarrhea.. should it have started to come out of his system already.

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 daughter, who is eleven, now, was on singulair for about 5 years. She has been having a number of problems for a while now, but we never thought about it being the singulair until recently. She was having anxiety problems, tremors, being very argumentative, irritable, angry, depressed, pulling her hair out, (trichotillomania). I started doing research on her meds. (Zyrtec & Singulair) and was shocked to find so many other people were having these same symptoms, including several with the hair pulling. I took her to her allergy doctor and just told him I wanted to change her meds. and that I didn't care if they say these are "not" side effects. It was worth trying to see if things would get better. Well, she has been off the Singulair for about a month and half, and I am happy to report her hair is growing back, and she says she feels happy again. It breaks my heart to know that medicine that we had been giving her for so long was doing this to her. I also have decided a few days ago to take her off the Zyrtec after reading a lot of the same symptoms for it on this website.

I was given a sample pack of Singulair from my GP for seasonal allergy relief. I take Zyrtec and Flonase on a daily basis anyway. The Singulair was suggested in addition to the regular medications, only temporary. I have been on it for 4 days and feel terrible! Have itchy throat, trouble sleeping through the night, although I am VERY tired, can't focus, swollen eyes and NOW red eyes...my boss just suggested I go home from work again to get some rest. I bet they think I drink during lunch! This is terrible and I will stop taking this tonight. I'd rather deal with seasonal allergies than this...

My son is almost 3 and was on Singulair for about a year and a half. We adopted him at 6 months old and for the first year he had pneumonia nearly every other month. The doctor suspected asthma and put him on nebulizer treatments and as well as Flovent and albuterol through an aerochamber. Not long after that he added Singulair.

I remember as a baby how calm my son was but as he grew his personality changed. I chalked it up to the terrible twos - until I found this website. After reading all of the posts and talking to a friend whose son had taken it for a short time, we IMMEDIATELY took our son off of Singulair. That was 2 weeks ago.

This is a common thread, but the change in him is nothing short of dramatic. He is happier, says 'no' A LOT less, gets along with our 2 year old daughter much better, sleeps better at night and generally does not have the 'meltdowns' he used to have several times a day. It is AMAZING!! He did have some coughing within a few days of going off of Singulair but we also have him on Zyrtec along with his asthma medications and the cough went away.

It's obvious what this drug is doing to children....if you have any doubts talk to your child's doctor but I for one will NEVER use this drug again and will tell everyone I know!

i am really glad i found this site, and got to really understand what may be my problem. its the SINGULAIR, i really believe. i will share my story so no one has to go through what i have been going through. (i just stopped my medicine a day or two ago, so i will repost and see if i start seeing changes in my behavior) well first off i am 19, and i started taking singulair when i was a senior in high school, so about 2 years ago. i didn't see any noticeable changes for awhile, except for probably a year now, a little more or a little less. for this whole time, i have not been sleeping, i wake up 3-4 times a night, fully awake and can never fall back asleep for hours. its almost like my body tries shutting down, but my brain never does, i have the craziest dreams, most of them are me suffocating or not getting enough air, which are really scary. I have been having really bad anxiety, panic attacks, basically i have been just feeling like i am going to die every second of the day. the feeling of being trapt inside my own body. it seems like every month it just gets worse and worse. i cant focus, i don't go to school, i don't work, and i believe its from the side effects of this medicine. i also always feel so tired, and so weak, i cant even look through a clothes rack without my arm aching. i have been having a hard time breathing, which is odd seeing its supposed to help me breathe, i have been sick at least once a month, through this whole time i have been going to my Dr. at least twice a month or more, telling her my symptoms, i even went in their one day crying i was so scared. and she just kept telling me, its probably all in your head, this, that and the other. she even put me on probably 10 different medicines trying to see which one would help. and of course none of them helped anything. I started thinking, and feeling like i was going crazy, what was wrong with me? i wondered constantly. For a couple months now, i figured i had to take it into my own hands to figure out what was wrong, seeing this Dr. doesn't seem to understand me. I looked up every disease or problem imaginable, and had blood tests done, but every thing came back normal. i didn't understand what was going on, every month i just feel worse and worse, lately i have been telling my mom i just want to die, that i cant keep living my life this way, of course i would not do this for the fact that i couldn't do that to my mom or my little sister, or anyone, but it feels like it would be easier then dealing with everything i have been. along with everything else i was/am feeling, i also feel a lot of hate toward myself, i feel like i am not good at anything, and i feel very ugly, sometime i don't even want to leave my house, because i just feel disgusting. Finally, a couple days ago, my little sister which is 10 and really smart i may add, was watching TV and they happened to have a commercial for SINGULAIR. she told me that everything i have been saying that was wrong with me (she hears me complaining a lot about all my problems to my mom) were all the side effects from SINGULAIR. of course i wanted to know more about this even though i have taken this medicine for awhile without any of these problems, i started researching and realized that all of my symptoms happened to be the side effects from singulair. and then i started reading other peoples stories about it, and about linking it to suicides and everything. i told my mom and i told her i wanted to stop the medicine right away, at least just to see if this is what it was all along. i haven't taken it for 3 days now i believe, and i already see a difference, i actually get tired now instead of staying up reading till 5 in the morning, and i haven't been waking up at all during the night. i am pretty angry that my dr. couldn't figure this out, or at least maybe even think about it. for awhile i thought i was honestly going crazy, i lived in fear for so long that something was extremely wrong with me, that i haven't lived my life the way i should of, or wanted to. i never thought that it was just the EXTREME side effects of this medicine. i am so thankful for my little sister listening to all my complaints and all my anger toward myself, and actually putting it together that it would be my medicine that was supposed to make my asthma better. as i said its only been a couple days and i already feel better, i will repost to tell you if im back to my "normal" self after being off this medicine for a longer period of time. i feel so grateful for my little sister, who would have guessed she would tell me what a Dr. couldn't even think about. i really feel that if i get back to my normal self, i really have her to thank for saving my life. <3

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.

NOW I SEE I AM NOT CRAZY. I JUST GOT OUT OF BED AT 3:30 A.M. - another sleepless night. I thought, I wonder if it is the singular - let's get up and do research. So here I am writing this is the middle of the night. I am a 56 year old female. Have been taking allegra for years, no complaints. History of smoking caused asthma-like symptoms which disappeared about a year ago due to improved lung function. I no longer need the albuterol, inhalers, etc. Two months ago I went to the dr. primarily to talk about depression and anxiety. History of depression and I've been taking welbutrin for the past six months. I decided not to change presc for depression. He suggested that I take singulair and switch to zyrtec.
WELL I CAN SEE THAT THIS IS JUST GREAT! I'm ill with everyone, depressed, have loads of anxiety, have three uncompleted projects in my house and was considering a fourth when I realize - now this is a problem! Wake up! So I find these postings and I am angry that all of this suffering has occurred, esp to children who can't explain that they feel different, etc.
So now I am going cold turkey, going to stop singular and zyrtec immediately. I am retired so I can take benadryl most times if I need to and I look forward to getting some good sleep tomorrow. (Will it leave my system that fast.) God bless you all and your children.
OH I FORGOT TO MENTION THAT MY MIGRAINES - WHICH WERE LONG GONE - HAVE COME BACK WITH A VENGEANCE. The nausea has been slight. OH - I'VE HAD TERRIBLE THOUGHTS WHEN I PICK UP A KNIFE IN THE KITCHEN WHILE PREPARING A MEAL. I INTENTIONALLY SHAKE IT AND WONDER WHY IN THE WORLD I WOULD HAVE SUCH A THOUGHT. I am so upset with dr. and pharm. companies. We need to take ownership of our own conditionsl.

I already had experienced some bad side effects due to singulair with my daughter. She had become moody, emotional, having nightmares and those are just a few to mention. However, my son had no side effects. When I went to my children's pediatrician, she agreed some children do experience some side effects like my daughter was having. But somehow she didn't see it as quite a concern. I vowed then and there to take both my children off it. Then my son continued having his allergies and over the counter zyrtec didn't seem to help him. I went back to the dr. and because I trust her and have known her for many years....she convinced my to put him back on singulair since he had never had any previous side effects. Well, its been maybe 2 months and now I see my son acting strange. He is not himself. The normal activities he used to enjoy don't interest him anymore. For the last few days, he has been wanting to lay down and he says he's sleepy. To me, he is acting like someone who is depressed and he's only 5!!!!!! I am taking him back to the dr. and taking him off this horrible drug! For all you parents out there...I think we should all go with our "motherly" instincts and do what we think is best for our children. We are the ones that know our children on a day to day basis..not the doctor's. So I am kicking myself for not sticking to my original instincts. My daughter improved drastically! Even her teacher noticed a difference. Please if you notice something, take action before the drug does more damage.

I was on Singulair for approx 3 years with zero side effects other than actually being healthy for the first time in my life - no chronic acute bronchitis episodes, no calling in sick to work. Then I switched jobs and HMOs - they immediately took me off of my Singulair and Combivent and put me on Qvar and Proair. Quess what? I began wheezing and sniffling. So they prescribed Claritin and Nasarel on top of the other two. Still not working. So now after a bout with antibiotics and steroids they have prescribed Flonase and over the counter Zyrtec. I have BEGGED to go back on Singulair repeatedly. I have offered to pay the $120/month out of pocket. Now I really am depressed and angry all the time - as well as having intense headaches, tremors, chest pain, insomnia, jitteryness then fatigue then jitteryness again = all because I can't get the stupid Singulair.

I am 39 years old. I was prescribed Singulair last month. I have bad allergies and have started to develop some asthma type symptoms. My doctor decided to try me on Singular before giving me an inhaler. I took the Singulair for 2 week and had to quit. After the first day, I developed a headache that would not go away, nausea and very vivid bad dreams. This lasted the entire two weeks that I took Singulair. I thought that after maybe a week, some of the side effects would go away but they didn't. So, I quite taking the stuff. I will never take it again. I am back to my Zyrtec for now.

I am 34 years old. I am a pharmacy tech. I have asthma and allergies. I have taken singulair pretty much every day since it came out on the market. I've had asthma since i was about 10 years old. I took theophylline as a kid. Steriods on and off especially during times when my allergies are bad. I still use Advair during the fall and spring. Every drug has a side effect. However breathing is pretty good damn thing. Do I have days when I feel low? Yeah. Do I sometimes have nightmares? Yup. Are "natural" products the answer. Not always. The fish oil that some of the posters are touting can also cause GI problems. Some of the natural products contain herbs and other plant derivatives that can be harmful for a child that suffers from allergies. Not proactively treating asthma can be deadly. Some of the parents are suggesting steriods as the answer - those can cause weight gain, growth suppression and can lead to a worsening of asthma.

Singulair has never made me feel like I've wanted to kill myself. I was more depressed and angry as kid when my asthma did not allow me to partipate in normal childhood things. I was sad and hated life when I couldn't keep up with friends at recces because I was having trouble breathing. You have to outweigh the costs with the benefits. I am more irritable when I have asthma flareup then I am on a normal day. For me, I choose to breathe. And singulair has been helping me for almost a decade.

I'm not saying the medication isn't causing these symptoms but maybe there is an underlying cause to your child's depression.

Any drug has a side effect. But without medical research and the medications that come with them - people would still be dying of simple diseases and we wouldn't have vaccinations. As a society, as a whole, we are a culture that looks to someone else to fix things and then blames the people who try to fix it. We need to stop being the "hot McDonald's coffee'" society.

I am totally upset by reading the posts here. my son is just now 8 months old. he was put on singulair when he was just 6 months old. at first it seemed to be working...for maybe 2 weeks...then everything went crazy. he was started out on it when his pediatrician stated that he had asthma and apparently was on a very high dosage of it. they started him on 10 mg of the oral granules. before taking it he was a very happy baby, even with him being so young i never had any problems with him crying excessively or being massively irritated. since he started on the medication he has had massive irritability spells, constant fussing and crying and cant seem to fall asleep at night let alone stay asleep very long. i had taken him to the emergency room on christmas eve because a new problem showed up. he now was having a massive hard time breathing, he had a persistant cough, congestion in his chest and was almost always gasping for air. the staff at the hospital were in disbelief when they were informed that his pediatrician had put him on singulair at such a young age and at such a high dosage. i am now in the process of obtaining a lawyer and filing a lawsuit against the pediatrician for medical malpractice. this drug is very dangerous for anyone especially children. i would suggest anyone else having these problems with their child and this drug do the same. it can apparently cause long term lung damage, pulmonary disorders and even death. my son has been off of the medication since christmas eve and has already done a massive turn around. he sleeps well and through the night again, his breathing has improved and his cough is almost gone. they did say in the E.R that he has congestion in his chest due to the singulair but it should clear up over time with the help of zyrtec. please help make a stand and protect our children from the dangers our own pediatricians present to them.

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:)

i had posted back a few weeks about my daughters situation on singulair well she has been off of the medication now for 3 and 1/2 weeks now and just starting last night she seemed to be a different child she has been on the med for about 14 months she is doing better in school not wanting to fight me on everything. now she is eating great which is scary when your child goes 3 weeks not eating due to being afraid.she was sent to mental health and the doctor said he had never heard of a reaction to singulair and she could go back on it we said it was not going to happen they said it was her being bull headed which we knew different.we were almost to the point where the doctor wanted to admit her to a physic unit . we had her off the med and within 1 week she started eating little by little we just about have her back to where she was.we video taped her having her fits and showed the dr. he just stated she is a handful. we let her see the tapes the other night she started to cry and asked what was wrong with her and we explained nothing baby it was the medicine that was making you do that and now everything is going to be ok .this is the 3rd time she has quit eating in 1 yr and we could not pin point it well now we think we know it was the medicine.they put her on zyrtec we only give it to her as needed not on a daily basis.

I have an 8y.o. daughter that has been on Singulair for about 3 years now. Since she started taking singulair she has been absolutely miserable! She cries at everything, is very moody, has leg pains, wont leave my side and is tired ALL the time. She has circle under her eyes, she looks like she hasn't slept a wink in days! She has been off her Singulair for about 5 days now and she is a totally different person. She has been "happy-go-lucky" and full of herself, she has even woke up happy (which hasn't happened in I dont know how long). She was put on Singulair by our Doctor b/c she had Pnemonia two times in a row. She has Allergies and Asthma and for the past 3 years has been on: Singulair (4mg), albuterol, flovent, Zyrtec, and Flonase. That is just too much for a little girl to be on. She hardly eats at all, gets headaches. I just see such a difference when she is not on it but, what will she take in place of this? My husband also takes Singulair (he is miserable all the time), he doesnt sleep at night and is always tired. Anyone have alternative to this drug?

are claritin and Zyrtec the same

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

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?

Singular has been recommended to my 3 1/2 year old son. I didn't feel good about it, so I declined and decided to look up possible side effects. Wow! I will NOT be giving it to him!
I have always been cautious on giving him antihistamines because prior bad side effects (which I never heard anyone else complain about).
When he was a few months old, he had cold like symptoms (runny nose, congestion, etc.) and was really suffering. I gave him the over-counter Pediacare and he could breathe better but he became something out of a horror film. He screamed constantly for over 48 hours and did NOT sleep a wink! Like a "crack baby" or something. (I assure you I am not exaggerating). I too became sleep deprived and crazed by his constant screaming, it took me some time to realize it was the meds. When I quit giving it to him, he became normal again. I decided I had to deal with the symptoms and not give him meds.
A year later, different medicine, I tried again. Same results.
When he was 2 1/2 we took a road trip from KY to KS. I thought I would try Benedryl, he had 2 older syblings that it benefited. NOT for him. He became "crazy" and screamed to the top of his lungs for the entire 12 hour drive. I vowed never again (for him or his family).
I have had success with Claritin in less than normal dosing. With no side effects. I have been assured, however, that Singular would work better for the symptoms. No thanks.
I feel really bad everyone this has effected negatively. I understand the side effects first hand.
I too have heard of the "antihistamine blocker" but don't know if it works.
I plan on trying a "nettie pot" (natural alternative) and have heard great allergy success stories. You can get them for about $5 at Walmart.
Hang in there parents! Do what you have to do for your child. Trust your instinks even over the Peditrician. I love Docs but YOU know your child. :)

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 son is now 31/2 years old and has been on Singulair since he was about 1 Yr. old. His pediatrician recommended this due to his allergies and runny nose. He has had fluid on his ears since age 1, at least that we had confirmed, and she thought that the Singulair combined with another type of antihistamine could dry up the dripping nose and clear up the ears. It did not clear up the ears, but it does stop the drip. He had tubes placed in his ears a year ago in May of 2007 and is looking now at his second set coming up in Mid-October of 2008. He has been taking this medication all but one summer of his short life. My husband and I have both had children, he a boy and I a girl, both 14 years old now. In comparison to the other two, our little one has been so completely different to raise. I've always seen children of "other parents" that have discipline problems with their children and wondered what might cause that type of action in such a small child. Now we have this beautiful little boy, but all we've ever known is how difficult he is to handle and how is anger, temper tantrums and stubborness have always put a damper on outings and even casual days at home. Due to the fluid on his ears, his speach was delayed and he has now really began to speak like a normal 3 year old. I have noticed within the last 2 weeks how he has really started saying things that I have not approved of, but have fluffed it off thinking that he has heard other children in his pre-school say these things, or heard it on a superhero show. Something happened today that really made me stop and think. I picked him up at pre-school like normal after work and he would not come to me. He looked slightly glazed in the eyes, totally not like himself at all. He talked very little on our 30 minute commute home, which was not like him. He said, "I hate you and you don't like me". I told him I do love him and he said, "NO". He said, "I'm bad for you and I have a dangerous heart". He then told me, "I kill you". This was so disturbing that I told my mother what he had said. She told me that it sounds so much like what she had heard on the news that I should check it out. This is how I've come to find this site. We have stopped giving this medication to our son and I am curious to see if there will be any change in his personality. Tubes will probably be placed in his ears again despite whether his nose drips again, so that is a mute issue at this point. When we voiced our concerns to his pediatrician when the information first surfaced several months ago regarding adult behavior and side effects of Singulair, she fluffed it off and told us she has many young patients on this medication with no adverse side effects. He is taking Pediox every 12 hours. I am worried that we may need a substitute med, but we have tried so many that haven't worked. He has Albuterol Inhaler and Xopenex Inhaler when his Asthma symptoms kick in, when his allergies are at his worst. He has had pnumonia 2 times, or one like run of it I should say. It's important to keep his allergies under control so he doesn't get something like this again, but his overall mental health and stability cannot be jeopardized. Since his brain has been developing on this medication for 2 and a half years, does anyone know if this has lasting effects? He is very active and has a very short attention span. He can however sit through an entire movie if it is something that he likes and he has nothing better he wants to do at home. I do not believe he is hyperactive or ADHD in the sense that he needs medication for that symptom. He can be a very loving child and he is very polite and knows his manners. He comes from a very loving home with loving siblings. We have wondered for so long how he could possibly have turned out this way, and I am truly scared to think that this medication could be the cause of so much turmoil in our lives. I will be monitoring his results.

I am a loving mother of a 5 1/2 year old boy. He has been on Singulair for over 3 years. In this past 3 years my son has suffered in an unspeakable amount. He came down with Rota Virus and was hospitalized at 2. He then came in contact with Pneumonia in the hospital while he was there. They automatically put him on Singulair, Zyrtec, Prednisone, and antibiotics to treat the pneumonia. Since that day, my son has gone though more tests than I have in my entire life. He has had asthma, sinusitis, leg cramping ( to the point he cannot walk for 2 years), IBS, Acid reflux,(they gave him laxatives for a year that made things worse and addicted to them also), stomach pain, constipation and diarrhea back and forth. He also got Erythema Mulitforme TWICE, while on this drug. All of which the doctors said could NOT be caused by Singulair. He has had several Upper GI's and CT scans. Along with Barium enemas, several hundreds of blood tests, and many many pokes and prodded that were not necessary. All since he has been on Singulair. He now has frequent bathroom trips, depression, confusion, and anger outbursts. He also has to go to the restroom every 5 minutes. He has had genital swelling, and many other aches and pains. None of which his "doctor" ever said could be a result of Singulair. I am 100% sure it was!!!! He currently has anxiety and emotional sporadic issues causing problems in school The teachers and counselors say that it is so strange because there is no TRIGGER and the outbursts are completely inconsistent. His preschool teacher and director are sure he has ADHD. Well, we had him tested and he does not have any part of it. He has no learning disability what-so-ever. So that brought me back to square one. He is in a positive loving enviroment. How could he be depressed and want to hurt everyone around him? He cannot sit still. He cries and says he is 'stupid" and "can't think" like the other boys. He has nightmares and cannot sleep alone. He is scared of everyone and everything. So, as I sit here crying, I realized that this has all been a reaction of his "medicine" Singulair. He never should have gone through all of those painful tests, only to prove they couldn't find anything. So many treatments and sound full advice speeches from his doctors. How could they be so naive and selfish in the life of my son?

When I called my pediatrician of 5 years, she told me that " parents that have children with behavioral problems will LOOK for something to blame their problems on." She also said "drug companies only put side effects on their labels to PROTECT the drug companies. (as she laughed at me) They are not always valid". Then she said "if you take you child off of Singulair you will be playing Russian Roulette in his life." Then she said that all children around 5 or 6 go though this emotional time in their lives." She told me that if I take my child off of Singulair that she would no longer be a part of his health regimen for his asthma. She told me to see a Pulmonologist for further treatment.
Who is paying who? This is my son's life???????? I decided to go with my mother-gut instinct and get him off of this medicine. No matter what. He has been a different person since. He is currently going though a lot of side effects and withdrawals (leg pain, insomnia, hic-ups, emotional distress) but every day is getting better. How can the drug companies say that this is a "wonder drug?" There are more reported side effected patients then clinical studied patients! How can a "medication" that stimulates the brain not be connected to other problems? This "medication" interferes with the bio synthesis and action of LTs and has been marketed as NOVEL medication against asthma and allergic rhinitis. Who the hell is playing God here??? The pocket books of Merck or our over PAID "doctors?" Who pays the price? Our children? Or us. Thank god I found this before it was too late. I would not be able to withstand the pain of losing my son due to their lack of scientific evidence. They are lucky I am one of the smart ones. I will not settle for less than Justice for the drug companies and their paid "doctors?" You all end up in the same place. HELL

There are 18 million people on this drug. Most of them are children. Please save a life if not your own child's life. Thank You

My son is 6 years old, and I started crying when I read the above stories. My son, too, was a completely different person when he took Singulair. Prior to taking it, we had a wonderful, close relationship and he was a well behaved child that excelled in school and got along well with friends. His behavior changed for the worse, but until now, I didn't connect it to the use of Singulair-I thought maybe he had childhood depression but didn't know why, as his life is stable and happy, and no major life changes had happened to cause the mood swings.
He would say his life was bad and he wanted to die for the slightest thing, he would say he hated us and punch us for just simple time outs that he usually complied to and he never ever hit us before. I have had him off of Singulair the past month, and give him Zyrtec occasionally when he really needs it, and he has not had one major moody episode, and he is back to his happy self again. I am joining the class action lawsuit above.

Well after reading these posts...I am very sad that I didn't read this before I allowed my 3 year old son to start Singulair! The last month he has been complaining of lower back pain. Just recently, stomach pain as well. Says his head hurts, and at times is not himself. I pick him up from preschool awaiting a very energized little boy to talk nonstop about what he did and he doesn't:( He was put on this med for allergies with Flonase and Zyrtec as needed. I took him to the doctors for this lower back pain and they said it possibly was from playing too hard or growing pains. Trusting our pediatrician I took it as that. My son continued to complain and continued to, at times, seem depressed. I took him to the ER because the last week and a half he has had fevers of 100-102. They said its all viral. I came home, looked Singulair up trying to figure out what was wrong and found all of this. I am so sad I never researched this before and continued to give this to my little boy trusting it to be good for him. Needless to say, I am making another appointment for him tomorrow to discuss other options. Thank you all for the information!

I have a 7 year old daughter. She is taking singulair. lately she has been complaining about pain in her leg it hurts when she walk. She also have pain in her arm. I gave her a pill tonight but I did not find this website until afterward. I am so glad I came across this site. She was taking zyrtec and she was having behavior problem. So the doctor switch her to singulair. I was hesitant to give her this medication. She also have seasonal asthma so I just got to find another way of treating her. I hope someone have good suggestions.

IS THIS SITE AN ANSWER TO OUR PRAYERS?

A little while ago less than two hours, after a very emotional, difficult battle with my daughter, we had yet another heart to heart to try to do better. At the end of our talk WE PRAYED for guidance to know how to help the situation. So I'm here looking for a link to her behavior fron the ADHD medication and I see someone had posted about Singulair side effects. I was floored! I have never thought that Singulair was not a safe drug. No doctor has ever mentioned any negative side effects to me regarding it. The more I'm reading about it the more in shock I am. Have I and her doctors been doing this to my daughter? My 12 1/2 yo daughter has been on Singulair for probably 10 years. She was a 28 week preemie and had severe lung issues so it was a needed medication. Her behavior has worsened the older she has gotten. Because of mostly anger issues and problems in school about a year ago she was started on ADHD medications. We are currently trying to find "the right one" . I feel so awful. Could all her misery have been caused by this little pill that was suppose to help her? Why has her pulmonoligist continued to give it to her although she has not had any serious asthma problems in years? I think I will stop all medications and see what happens. My daughter has also been on amytriptylin for about six months also for severe migraines. What do you think? Should I stop all of them cold turkey or gradually decrease one at a time? I would GREATLY appreciate any advise.
Thank you

I just started the Singular and it has helped my asthma a lot. I can't tell about the coughing because I also started it while I had a cold. But now and then even before I took singluar I would cough. Sometimes coughs are produced from various types of airborne things, many different types of things. I have a mold aggreviated asthma so that could be why its helping my instead of causing me to go nuts like it does for some. But it doesn't sound like a very good drug for children. It seems as though none of the posts coming from children taken Singular are positive. But so far it's helping me. I made it through the day without grabbing for my inhaler which was a great relief for once.

SINGULAIR AND ZYRTEC SAME MEDICATION made by different companies. Be careful!

I have been reading all of these posts and have another question. I hope that someone can help. My daughter, 8 years old, has been on Singulair since she was 4. She is normally a very happy girl with a wonderful disposition. For the last year or so, she has been having trouble getting herself to sleep at night. She says that she hears things in her head such as ringing or "noises". A few hours before she knows it's bedtime, she cries and when we ask her why she's crying, she can't give us a reason. We initially thought that she was crying for no reason because she didn't want to go to sleep. I remember reading about the side effects of Singulair causing mood swings, etc., but her's are not violent mood swings. Just very emotional and has a hard time coming down from the "episode". I'm at a loss...I have not talked to her doctor yet about it, but have told her that we will make an appointment this week to discuss it with him. My husband suggested that maybe it sounded like she was having a panic attack or anxiety attack. I hate to label her as that at such a young age. My mind now goes back to the side effects of Singulair and maybe this is to blame. Any help or suggestions would be greatly appreciated. Thank you! Concerned Mom

Have been experiencing the same serious behavioral issues (screaming, launching every toy he has out of his room, knocking over his night stand, hitting, kicking and just being hateful) with my 4 year old who has been on Singulair for 2 years as I'm noticing many of you have here. My wife and I have a wonderful relationship and happy home and tons of love and support from other family that's close buy so the kid has a very nice environment. We have taken him off the medication as of yesterday. I have consulted his doctor but I'm anxious to hear what methods of treatment for the asthma all of have chosen in replacement of Singulair or did you just maintain with an inhaled maintenance program with something like Pulmicort? Also, how long was after taking your child off of Singulair did take to for the outburst to subside and the behavior to become more mellow and normal (what is normal for a 4 year old?). Any info would be greatly appreciated.

Sales of Merck's asthma and allergy drug Singulair dropped 1% to $1.1 billion for the second quarter. U.S. sales have been hurt by the recent introduction of an over-the-counter version of rival drug Zyrtec by Johnson & Johnson (JNJ), as well as concerns about the Food and Drug Administration's March alert of a possible association between Singulair and suicide and related behavioral side effects Got this off cnn money,i don't know but thought zyrtec and singulair were different drugs,my son at one time was prescribed both to take at bedtime

My son has been taking Singular as well as Advair and Zyrtec and Nasonix for the past 6 months. He is doing so well. He has not had to go to emergency, he has not been sick, and he has not had mood swings. If you look at the prescription information that comes with Singular, you can see what the side effects can be. My recommendation is to take your child off of them if they have a side effect. I contacted my Dr. and Merck is studying only 1 case with a child that had side effects, but they did not say if this child was on other Psych medicine at the same time. The 2 psych meds that have shown a bad interaction with Singular are Phenobarbital and Rifanpin (spelling may be wrong). With all the posts I have read, very few people indicate if they are taking other medications at the same time as Singular. My suggestion is that you consult your Dr. and then send your case to Merck for more studies. If all you are doing is posting on the web, you are not solving this issue with the makers of the medication.

After reading all the horror stories on here, me and my husband soon began to realize that we were having a lot of the side effects listed here and not listed on my son's actual Singulair prescription. The side effects my son had were behavioral changes, irrational behavior, inattentiveness, not able to stay on task or stay still -- in fact he broke his arm twice being so hyper, yelling, screaming and just plain mean.

We took our son off of Singulair as a trial for a few days. Immediately we began to notice differences in his behavior. He wasn't as agitated and quick to yell or get angry. (He's only 5 years old). He actually would be listening when we would speak to him. He would sit calmy and read books and the one huge thing he would do was look at us and smile. He even said to my husband once, "I love you Daddy," which just brought tears to our eyes. I never realized what a Singulair fog he was in and what it did to him. Here we were pretty close to getting him evaluated for ADHD or even Aspergers. So now we're in the same boat as others that are searching for other asthma meds to give my son. Right now we have gone back to Pulmicort, Xopenex, Nasonex and Allegra. I'm so glad I read this forum because I was desperately searching for answers for my sons behavioral issues. Oh, by the way he was on Singulair for 1-1/2 years.

In 2003 at the age of 31. I had been taking singulair for over 2yrs. I started experiencing muscle weakness and I got to the point I could not sit or lay down. I was extremely in a lot of pain and taking large amounts of pain medicine. It went on for several weeks. I went to the doctor because I was having muscle spams or what I thought was a ruptured disk. I had a MRI done and it didn't show anything. I was sent to a back surgeon and he checked me out and wanted me to list all my medications. I began to tell him about zyrtec and singulair. He asked me how long I had been on singulair? I told him almost 2 years. He told me to get off of it right now because it would kill me. He said the singulair was deteorating my muscles
and causing me to have muscle spasm. I had no muscle tone. He sent me to a massage therapist 3days a week for 6 weeks and I came off of the meds. The doctor told me he had at least 10 patients that had happen to them.That was a wake up call. The doctor also told me his wife was on it 6 months and started throwing up blood and took her to the ER. All because of singulair and my kids have been on it for 3 years and have not had one problem. They are 10 and 7.
My husband is a pharmacist and he had not heard anything bad about it. He filled out a card about the side effect. It only happens in 2% of people taking it.
