My 6 y/o daughter has been taking Singular for approx. 2 years. She began to have regular somach pains shortly there after. She was sent to Children's hospital where they put her on a laxitive which made things worse. Then we began testing for food allergies only to find out that she tested positive for a 3 page list of foods. We eliminated those food and had her tested again. She was subsequently allergic to the foods we eliminated. She was recently down to rice, a few meats and some vegetables. Guess what, she is now allergic to those foods.

All this time she has been complianing of severe leg pain, eye pain, throat pain, numbness and tingling in her hands a feet, all of which come an go. I have reported this to all the doctors and specialists we have seen. She had undergone countless blood tests to rule out autoimmune disorders and all come up negative.

She began to develope severe anxiety and just had the blues most of the time. She would be crying and saying off the wall things like, "I don't think my fish is happy". She couldn't stand to be away from me and would stress out about even weather or not she would sit by me at a restaurant. I mentioned this to all of the doctors. They said to not make too much of it. One suggested she see a psychologist. NOT ONE DOCTOR EVER LOOKED AT THE SINGULAR.

Finally about 4 weeks ago my neighbor who is a scientist at a pharmaceutical company called me and told me about the "black box" warning that had just come out on Singular. I took both of my children off of it immediately. My daughter went through about a 10 day period where her anxiety got worse and then it was just gone. We are adding foods back into her diet and at this point she has not had any severe allergic reactions.

The last 2 years have been a complete nightmare for her and for us. I am a medical professional and I have had doctors treat me like a hypocondriac, hypersensitive, attention seeking mother. I feel so justified and saddened by the recent findings all at the same time. Most of all I am so grateful that we figured this out before things go even worse.

Please let me know if anyone else is suffering food related reactions as a side effect.

PLEASE READ CAREFULLY:

To all the parents who are wondering what else their child can take as an alternative to Singulair, please read an exact quote from a leading professor of Pharmacology and Pediatrics at the University of Florida:

"In response to your last comment, I think Singulair has modest efficacy, and if we take all of our patients off this drug, they won’t suffer. This is not an important drug for pediatric asthma, as are inhaled corticosteroids."

There you have it folks. Singulair is NOT an important drug for pediatric asthma and has an overall moderate efficacy. Inhaled corticosteroids have a much higher efficacy. I have communicated directly with this professor through email.
Any questions??

My son became soo aggressive 3 days after starting Singulair, that he was almost banned from soccer for life because of attacking another player on the field. It resembled what I had heard of 'roid rage'. When I questioned the doctor immediately, was told there was no connection. After months of the aggression, then came depression and self mutilation. My 15 yr old was secretly burning himself to 'punish' himself for things he done wrong or "disappointing" those around him. He now has permanent scars all over his arms from these burns. The depression took to drug abuse and my A student fell to an F student in 6 weeks. He completely lost his will to live and thrive. After 4 months of hell, the dr informed us that the FDA just warned physicians of this side effect. Im furious now that I read through the court documents and find that the drug company knew this all along. I know I am a luckier parent than some whose children committed suicide, but still wish that the FDA would get off their BUTTS and do something to take this drug off the market. I was told by a rep at the FDA that Merck will not take it off the shelf until they're made to because even if they had to pay parents millions for their child's suicide, they would still be pocketing more profit than our children's lives are worth in the court system. Not sure WHY we even HAVE an FDA, they won't do anything to protect us from these money hungry drug companies. A YEAR to do an 'INVESTIGATION" are you kidding me? If the CEO of Merck had to bury his child, it would come off the shelf THAT DAY.

To all the Parents out there that are outraged at what Singulair has made your child and family suffer through - Please, please take a moment and file a complaint with the FDA. It is a simple form you can complete on the computer. This product should not be dispursed like candy to our children. It is amazing the number of doctors that are unaware of the severe side effects that this drug has. Our children suffer and we keep poisoning them under the illusion that we are helping them. We tend to blame the abnormal behavior on growth all the while punishing them for it. It is a horrible, horrible cycle.

I am a parent of a 14 year old son. He has been on many meds due to having migraines, adhd, seizures, and asthma. For 3 years his ADHD meds have been switched. Now Thanks to a friend she told me about singular side effects. OH MY GOD. it blows my mind reading this stuff. He has been on singular for 3 years and never once did I think all these problems were caused by that drug. Flipping out over the smallest things, arguing with us his parents, his friends, being mean to us and a real smartass, depression, and MAJOR attitude. Getting upset over nothing at all then crying for no reason What was his Dr. thinking? Needless to say, I took the singular while she was telling me this stuff about her own son, and threw them away, I will never allow my son to take that shit again. I hope in three days like all of you say, that my son will be that loving, caring, friendly person he use to be ! Singular free is how he will be!!

I am a grandma to a 41/2 year old boy named Trevor. He has been on Singulair since he was 18mos. old. I am here to tell I am furious and heartsick to think that he has been subjected to a medication that can do the things it has done to him. I have NO DOUBT that Singulair is the problem. Our daughter and son-in-law have been at their wits end with
him and was one phone call away from taking him to a therapist (they needed one too!) The phone call to me on Monday, July 28th, was out of
sheer desperation. My daughter wanted me to look up the side effects for Zirtec. After looking that up and not finding anything I happened to remember that Trevor was also on Singulair. The actual side effects listed
didn't ring any warning bells with me. Somehow I happened onto this website and OH MY GOSH I flipped out and cried through every letter written by parents with the same side effects Trevor has. The compulsion, anxiety, anger and (heaven forbid) the threats of wanting himself, or someone he loves very much to die.This is absolutely unheard of for someone his age. I'm ever so thankful I found this website. Trevor was taken off Singulair that very day and within 3 days we had the sweetest,
most normal 4yr. old, on this earth. When I think what could have happened
had he stayed on it any longer...I can't!!!

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.

Dear Friends,

Just want to reconfirm that this drug, that according to the Lab, present this side effects as "rarely" now we can see that it is not, I have a 2.5 year old boy, that is presenting these same side effects that you are mentioning. In a sudden he starts to act really nervous, his eyes turn red and cries while he tries to express something, but he does not know what is going on, in the meantime he has this truly visible crisis, his heartbeat goes up like hell, and his hands shakes. My wife and I got really scared the first time we experienced this with him, and we did not know what to think, we asked the Doctor and the stupid guy told us that he needed a shrink, but we did not believed it. Today he had the second same crisis, not as hard as the last one, and we discussed and came up with the idea to find out what were the side effects of this drug, and voila, is the gdm Singulair. I just can't believe that the Doctors that are prescribing these drugs do not warn the people that this may happen. The only thing that I can do is write my experience to you, thanking you for your attention, and spread the voice to the other parents that are around me that they take care of this and prevent their children to go through this process. I really feel like trash, because I did not do this before starting giving him this drug. Thanks for listening.
By the way this is an international problem, I am writing you from Mexico City.

My 3 years old daughter was on Singulair for 8 months, that was prescribed by her Pedestrian from the Asthma clinic in Canada, Quebec. Lately, some of the symptoms of adverse effects are surfacing in her, including depression, action very emotional, constant having bad dreams (which causes tiredness), crying almost whole day in the daycare, refusing to eat and drink, refusing to join her favorite activities... Her Pedestrian told us there is no side effect on Singulair when she renewed the prescription 2 days ago. Because of my doubt about that, I started research on the web and found out that the early communication was issued by FDA. Of course, I took my daughter off from Singulair right away.

I work in the drug development clinical research field. I know that nothing the FDA or Health Canada will pursue until a lot of cases on adverse events (side effects) reported to them. Please everyone, if you or your child has had developed any side effects on this particular drug (Singulair), please report to FDA at once. It got me so upset is that this drug is constantly and widerly prescribed to children, and the Pedestrians are not caution enough to tell the parents. I definitely do not want to see other children suffer the same symptoms as my daughter had.

I'm seeing some posts from parents who say their children have returned to normal after discontinuing the use of this medication. However, there seem to be a lot of diagnosed "ADHD" or "BIPOLAR" conditions. Are your children really returned to normal? Or have they been diagnosed with a psychological issue and are receiving treatment? There seems to be a connection here, even after discontinued use, especially male adolescents. Any thoughts?? The increase in cases of ADD, ADHD, AUTISM, etc has been multiplying at a very disturbing rate in the last 10 years. I'm thinking definite connection to the "new" breed of "receptor blockers". What is it triggering? Any thoughts out there? Lets post anyone with similar cases and see how many are out there.

I have only been taking singulair for about a month. I have noticed that I have become more irritable, grouchy, hateful and just numb, not really wanting to be around anyone, not caring about anyone else's feelings much. I also noticed I have become extremely lethargic, to the point of falling asleep at work as well as heart palpitations and stomach pains. I just started new birth control pills so at first assumed they were causing these side effects, that is until I looked up the side effects of this drug! I have over half of the side effects so I stopped it immediately and can already tell a difference in my mood. I have to sons age 11 and 14, both who have asthma and allergies. The took this medication for a few years with no side effects but have not taken it for about a year now. My youngest son however, has been diagnosed with ADHA and ODD and possibly BiPolar disorder. As I read the other posts, I realize the description of how their children act while on this drug is exactly how my son acts. I wonder if there can be irreversible permanent damage from taking this medicine? He has been on a number of ADHD drugs, none have helped except to make him stop eating and lose weight and he is small for his age, so I have taken him off everything. Has anyone else out there experienced what could be permanent damage from this drug in their children? Even after being off the drug for a year or so? If it could make me miserable within a month, what can it do when one takes it for years? Its sometimes hard to tell the effects of medicine on small children. My son prob starting taking it around 4 yrs old and took it til he was about 8 or 9. Just wondering if anyone else out there has had this happen to them or their children.

My son, now 10...has been on singular off and on, since I don't' know how long...today was the second time he was intentionally hurting his cat. He has told me time and time again about visions while he was awake, violent ones, he argues with anyone and everyone. He has no friends at school. Last year I took him off all his medications to see why his behavior was so drastic, he got so calm, it was like a new boy, but then when he started back to public school...he had to be put back on them again, and again with the singular...
If it was not for this site..I would think my son was sick mentally. But after this...he will see his doctor tomorrow and no more singular...
When I took him off all the meds I told his doctor I was really worried about his behavior and they said it will be okay...he went right back to just out of control. Could not sleep, concentrate at school or at home. He is so smart and he is failing school..not because he is slow, but they kept saying he was add...but when I home schooled him and took him off his meds...he was so great, obdient..not perfect by no means, but just a normal boy...
I hear him right now, in the other room, fighting imaginary people...he seems to go go go..and with no sleep...the dreams in the day time I just thought were his imagination...but now that i hear about other children like him...they are to him real..just like he tells me..he also always tells me how mad he stays..he says all the time I am just angry mom, and I would say at what..he just says everything...
Thank God for this site....now i know..it is not in his head, it is just like I told his doctor...it is his medication..now I know just the one it is..
THank you all..
God Bless all the others here suffering with the same problems...it is just shocking that we as parents and patients, even after telling the doctors, are right...I feel vindicated...I will be printing this off and taking it with us to the doctors...

Hi everyone
My little boy who is nearly two was put on Singulair as a preventative.
I did check on forums when we started using Singulair and I was concerned that there has been descriptions of negative affects. Always trying to be objective I rationalised that the people in this forum are a small part of the greater Singulair population and as a result there was a low risk of negative affects on my little boy.
I have to say I think I was wrong. As soon as he was using Singulair, he had restless nights of sleep. Every night he would cry off and on until 2am and I guess he was so tired he slept. During the day he was very short tempered and became upset very easily. We put this down to tiredness. After 10 days of the lack of sleep for parents and little one, we told our doctor.
He advised to take him off Singulair for 5 days and make observations and then put him back on. Last night, his first night off Singulair was bliss. Not a sound. He had a great sleep. As I type he is now having another great sleep.
Let us see what happens after 3 more days and after putting him back on Singulair.
It would seem that if we are correct and that Singulair is a cause of an issue for my child, am I a quasi beta testing laboratory for a drug?
We are from Australia.
Thank you for reading.

I am finally writing after reading these posts since the end of April. That is when I took my 11 year old son off singulair, in an act of desperation. He has been on singulair on and off for about five years for seasonal allergies. He started again in mid-March so it could get into his system, before the allergies started. Immediately thereafter his behavior changed. He was arguing on a daily basis. He would hit, kick or trip me when he was angry. He was starting to destroy things in anger. He seemed to be fueled by anger. It was affecting the whole family. He was starting fights with his younger brother, my husband's heart was palpitating and I was crying every day. I heard about Singulair side effects and looked it up. I saw that it caused behavioral changes and out of desperation, took him off, not knowing what to expect. We had three days of total peace, then on the fourth day another outburst. Then my son told me he had taken a singulair the night before. That was it. I threw every pill in the garbage. He no longers acts like that. It's been almost two months so I am convinced it was the Singulair. By the way, he always complained of headaches, stomach aches and would scream in his sleep. Who knew - it was the singulair all along.

Who administers this site? I posted a side effect last night after I registered and then this morning I got an email saying there was a reply to my posting and when I tried to log in, my account was inactive and my posting had been removed, as had the reply to my posting. I don't know if it is because I put a link the an online reporting tool where the FDA is compiling feedback from people/or their children who have experienced terrible side-effects. Here is the link again and I urge you all to report your cases: http://www.fda.gov/cder/drug/early_comm/montelukast.htm

My son is 3.5 and has been on Singular for 2 months and just like all of the other stories about the other young children posted here, he is a different kid after being on Singular. Last night was the first night I took him off of it. All of the side-effects that are mentioned here are the same ones my son is experiencing, nightmares (screaming in the night), hyper, aggressive, reliving injuries from days past, the day care telling me that they now have concerns about how different he has been lately and the even used the term "bad behavior". They said he is hyper, he screams, not listening, aggressive. He is a favorite at day care since he is so loving, polite and kind. I know all parents say that, but pretty much anyone who has met him compliments me on how well behaved he is. I am even nervous to have people over since he seems out of control and I have found myself ensuring people that he isn't normally like this. I have taken him off as of last night and I am hoping he will get back to his old happy-go-lucky self soon. Does anyone know how long it can take to get this poison out of their system? I pray that there are no permanent side-effects.

Well, we just got out of the ENT and he couldn't believe that his ped put him on Singulair. He said he didn't like it, it wasn't a good drug, and hadn't heard of many good things about it. He also told me to take my son off immediately, to bad I already had. He also wanted me to put him back on Zyrtec but only when needed, not every day like he had been taking it. Told him about how the neb. had been talked about so he listened to my little one's lungs and he said that they are all clear and there is no need for one. While I was in this appointment, his ped. called. She said that she had never heard of any side effects with this and she wanted him to stay on it for a week to see if it worked or not. Sorry we aren't doing that, we had four doses of it and that is more than enough to say we aren't staying with it. This is just his first full day off the med and I shouldn't get all worked up but while in the waiting room to see the ENT we had two huge fits and even hit his head on one of the chairs because he didn't get his way. The ENT said to give him about a week to go threw "detox" and get it out of his system and then he should be back to himself.

Also, on top of the big mood changes and swings we didn't sleep good last night and had another fit of rage in the waiting room of the ENT. Not fun at all.

WOW!!! I am glad I came across this website. I have twin boys that will be 7 this month. One has been on Singulair for about 3 years for allergy induced asthma and my other son has been on it for 9 months for allergies. I am taking them both off of it today. The son that is taking the medicine for 3 years has become increasingly angry and gets upset over small things. Over Memorial weekend, he lost a game he was playing on the wii and exploded. He was banging his head and then started to hit me. NEVER in my life have I seen him attack anyone. A few days later he threw rocks at his friend because he wanted the wagon. Over the past 3 years I have noticed some change in him and just took it as growing pains. He has always been a strong will child. However, over the past 3 years he has gotten worse and since he has physically attacked me and his friend, I have decided to send him to counseling. Now I firmly believe it is the Singulair.

My other son has been on it since August. He started to have anxiety within a month of taking it. His behavior has been stressed, depressed and not wanting to play with other kids. He was biting his nails to a nub, licking his hands, not talking to anyone at school and rubbing his head. I have also noticed he does like to look at the person he is talking too. Of course I thought the worse and thought he was being molested. I went to his Teacher and she has worked very hard with him, but he is still a loner. If you knew him before, he played with everyone and enjoyed life. I was told by his Ped. that he had anxiety and to have him see a shrink.

I am hoping that after taking them both off this medicine, I will see improvement.

My 5 years old son has been on Singulair for 9 months. His allergy symptoms have completely gone away. He’s no longer has his night time cough, bloody nose, and frequent croup due to allergies.
My life has been a living HELL from the moment I started this medicine. Before he was on this medicine he was always a pleasant, smart, well-behaved child. Right after he started singulair he began having temper tantrums, becoming increasingly argumentative, not listening. He gets mood swings like you would not believe cry and/or yell at us over the silliest things, kicking, screaming, nightmares, and became very physically aggressive. We were unable to take him places because we never knew how he would behave in public .He was extremely unhappy little 5 year old boy. He also complained of upset stomach and fatigue. Even his school complained about his behavior and they said that he might have PDD. After consulting with doctors we got the assurance that he does not have PDD, but we end up changing his school anyway.
Being a first time mom I never thought it was the medication, I thought it was just a normal behavior. I thought as a parent I must be doing something wrong! I couldn't believe that other parents have gone through the same nightmare.
Two weeks ago the doctor handed me a report about singulair and its suicidal side effect and ask me to stop using this medicine for a while. Since then I started to notice a dramatic change in our son's behavior. He woke up singing, laughing. He wants to help with chores. He is doing great with his school lessons, and very patient with everyone. He is now a more stable and friendly 5 years old.
Wow, I have a completely different child, and thank God I took him off singulair.
As parents, please let’s do something to stop poisoning our children.

hi, im not sure what to do. my 3 1/2 year old daughter was today given the prescription for singulair. i voiced my concerns to the doctor after my friend telling me its no good due to the side effects.she said that there are risks and side effects with any drug you take but for some reason i don't feel right about this. don't doctors know better than this. anyway Would like to know if all the people who take singulair suffer some sort of side affects or is it minimal? or going by this side it looks like its probably best not to give it to her at all.

Our daughter is 17. She started taking Singulair June of 2000, 8 yrs ago. Upon hearing the side effects I insisted she stop taking the drug due to the fact that she also showed extreme signs of agitation, irritation & was always angry & frustrated by everything & everyone around her. Her standard comment was " I know I'm mean & rude". As a parent you know your child & we knew something wasn't right but never suspecting this drug. She as a young child never exhibited any of these signs. She was evaluated by 2 psychiatrist in these past 8 yrs., ADD was one of the diagnosis & our concerns that there may be some bipolar symptoms. After taking her off the Singulair there has been an obvious improvement that is evident to all the family members. The Singulair did an outstanding job of helping with her allergies which are severe & also contributed to multiple sinus surgeries. But the trade off? We are absolutely convinced & she is too that the Singulair had a debilitating effect on her personality. She once again talks, laughs & is such a joy & pleasure to be around. I will add that she never felt any suicidal tendencies, but just severe agitation, irritation, impatience & her reactions to situations & people around her were completely out of balance. I will always be convinced given our experiences that Singulair was completely responsible for 8 yrs. of heartache for us as her parents & 8 yrs. of misery for her.

I would like to urge everyone to report adverse drug reactions to the FDA. Without a supporting data base, things move way too slowly and other people get hurt. I was doing some further work on quinolines/quinolones and ran across a medical researcher who starting writing about quinolones in 2001. The warnings that finally appeared on the quinolone drugs were placed in 2005. Let's do everything to keeping that from happening to parents.

Here is the researcher who wrote about quinolones so that you will have the reference.

My son is almost 9, he has been on Singulair for 3 years. Last Friday the pulmonologist took him off of it. My son has been sleep walking since about the time he started singulair, have noticed major behavior changes. He gets very angry over nothing, he is extremely sensitive, he is not the happy little boy he once was. He has horrible dreams. Over time this has gotten progressively worse. I have to say that since last Friday when he was taken off the singulair, I have noticed a huge difference. My happy little boy is coming back! I told the Pulmonologist my concerns ans could this be side effects and he replied "YES", Also, he feels that my son has outgrown his asthma which is wonderful. I feel so horrible for all these children and families going through this. Parents, remember you are your child's best advocate. don't let the children suffer.

In September of 2007 my then 13 year old daughter was put on Singular for mild asthma. At the time she was a straight A student, vice president of our school and a popular girl who's guidance counselor described as "the glue of her grade" because she was so well liked. In November she told me that she was struggling with advanced Latin and Science. She asked to drop down to on grade Latin so we did. In December her science teacher notified us that she had a C average. She told me that she thought she had ADD/ADHD and she couldn't keep up. At the same time she was having a lot of problems with friends at school and we just attributed it to being 14. 3 weeks ago we discovered that she is significantly behind in English and it was then that she told me that she is been having horrific night mares. She said that they usually involve someone killing her or her killing herself. She said that they were so graphic that she couldn't repeat it out loud. She also said that she would feel waves of anxiety that would come over her at school and she would act "witchy" to the kids in her class for no real reason. She said that sometimes when she is trying to do her homework she will read the same passage for 2 hours and still have no idea what it's about. She also said that the suicidal thoughts from her sleep happened during they day and that she had thoughts of her harming herself. Fortunately her pulminologist told us that this may be caused by singular and we immediately took her off of it which was 2 weeks ago. She has only had 1 "bad dream" not even a nightmare since. She had one anxiety attack 3 days after she was off it and she describes her moods as the "cloud lifting....slowly". Now, we have to pick up the pieces. Her grades have suffered, her friendships have suffered and most of all her self esteem is very low. I'm grateful that we found out the cause but I feel as if my daughter lost a year of her life and I worry that because Merck won't admit there are side effects we can't find out how long it remains in their system. Is anyone else concerned about the long term affect and has anyone pursued a class action suit to try to get this drug tested properly?

This is a follow-up. I have posted about our experience before, but to summarize: 6 year old boy on Singulair for over three years for Asthma. Drug worked wonders, but side effects developed so slowly that we thought those were "phases" that would go away. Side effects were just as everyone else reported: nightmares, fears, depression/sadness (we even went to a child psychologist since we thought this behavior was all due to father's deployment), aggressiveness, crying at the drop off a hat (like a 2 year old, not age appropriate), attention deficit, school performance dropped, and also, at the very end, obsessive compulsive behavior.
We stopped Singulair as soon as we heard about the FDA investigation (on NPR, about 6 to 7 weeks ago). Asthma has not worsened, thank goodness, so we make due with the Flovent for now. Most of the side effects were less prominent after some time, however the obsessive compulsive behavior stopped only a few days ago. We have better days, we have worse days, but slowly the better days outnumber the bad, aggressive, and negative ways.
What I read again and again in the postings is that we all assumed our children entered a bad "phase." A phase that just got worse and never ended!
Reading about the very same side effects in our children, over and over again, alarmed me. Taking my son off the Singulair and seeing the improvements, some faster some slower, totally convinced me. I will never ever have Singulair in my house again.

Wow, I just found this site. The child that had strep especially caught my attention. My daughter, 11, has been diagnosed with PANDAS, which is also a controversial diagnosis. I'm not sure when she went on Singular, but it was a couple of years ago due to allergies. She had bad reactions to anti-histamines. For the past two years we have been dealing with just about every issue posted here. Physical pains, stomach, headaches, joints. urination issues, high cholesterol, but the worst have been the irritability , mood issues, OCD, fears of cutting herself, bad thoughts, suicidal ideation. She was on Zoloft which made things worse, She was hospitalized at her own request. She was placed on Prozac. She's had years of therapy. She would say life is just so hard and she wants to be a normal kid. About a month ago her pediatrician mentioned that there were some reports about Singular and it would be something to watch for and discuss with the psychiatrist, He didn't seem to know much about it. Last week after another suicidal ideation I decided to research the singular issue. I had been attributing everything to the PANDAs. I was so surprised to see the similarities. I took her off of it Friday and have seen some changes already. I hope we see that continued improvement. Thanks to all who have shared stories, it's so helpful. To have hope that you'll get your kid back is great.

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 have some more questions for you guys. I am looking for connections to the killer t-cells that appeared in asthma cases. I would like to know if your child was vaccinated for hepatitis B, at what ages, and if you child has asthma. Also if your child was one of the ones vaccinated for rotavirus.

Thanks in advance.

My 4yr old son has been on allegra for 2 yrs now and it seems that it wasn't doing much anymore. so our doctor prescribed Singulair. He gave us a two week trial to see if helped. Well!!! Our once happy go lucky 4yr old is now very emotional and gets upset very easily and can't stop crying ( even says he can't stop crying) when he gets upset. He is unable to console rationally when he is worked up. Today was the last dose of the two week trial and I after reading all this, it was and will be his last dose...

Parents beware of Singulair
I would two to one rather chase him around with a tissue.

My 2 year old son was put on singulair to help with asthma and allergies. Within 2 weeks we noticed a change in him - he wasn't the happy boy he normally is. We wound up in the ER one weekend after he had 3 petit mal seizures. The ER doc diagnosed febrile seizures. I wasn't convinced. Our pediatrician didn't agree, either, and sent us to a neurologist (but he didn't think singulair was the cause). The neurologist also hadn't heard of seizures associated with the drug.

My poor boy had an EEG and was in doctors offices, hospitals at least once a week until the EEG results came back normal - scary for a 25 month old child. I stopped the medicine immediately after our ER visit - call it mother's intuition. He hasn't had a seizure since. Although the doctors aren't convinced singulair caused the seizures, I firmly believe it did.

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!

Chris555, our stories ARE proof. 99% of us have medical records to prove the problems our children have gone through. Not just one doctor, many doctors. Nothing that these doctors suggested worked. All of the tests, added medications, etc. But when Singulair was discontinued almost EVERYTHING went away within days. How can you ask where is the proof???? Sure, no one wants to have open up medical records etc. but I would be more than willing to do what it takes if it will save others the anguish our family has gone through. Imagine losing a child to a drug that you had no idea could even cause such things?? If parents were only warned.....

(A divorced father)
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.

Our son started taking Singulair when he was 2 for severe allergic rhinitis and cough variant asthma (in addition to Zyrtec, which didn’t control all of his symptoms). He is 5 now. For the last three years, he has been an increasingly violent, difficult, defiant, argumentative, volatile child who has intense mood swings--one minute he’s laughing uncontrollably, the next he’s weeping over nothing. His doctor and therapist recommended that we see a psychiatrist to have him evaluated for bipolar disorder, which used to be unknown in children. Because he has such chronic sleep problems, the doctor also suggested we take him off Singulair (and increase his Zyrtec dose) to see if it improved his sleep issues. Within a week, he was sleeping much better and was a calmer, happier, gentler boy. He suddenly could take “no” for an answer without flipping out and trying to hurt me. We thought that we were just in an unusual, calm window that would shift either to mania or intense sadness or both, any minute. We also thought that his behavior change might be due to sleeping better. We were enjoying the rare reprieve. Over the last weekend, his springtime allergies really flared up. We gave him Singulair on Monday and by noon, he was completely out of control. I had to strap him into his car seat at one point to keep him from hurting either me or himself. It finally occurred to me that Singulair might be causing his “bipolar” disorder. Of course, we stopped the Singulair. After two days he was a new boy. Yesterday, I Googled “Singulair bipolar children” and got a few hits. I am stunned to read how similar other families’ experiences have been to ours and I feel sick that we gave this drug to our child for three years.

Neurological problems and the effects of Singulair should be investigated. The Chinese researchers demonstrated that the CysLT1 receptor (singulair inhibits this receptor) does exist in the human brain. In the rat brain, they demonstrated that there is a link between this receptor and the astrocyte.

There are many researchers/doctors interested in excitotoxicity and damage to neurons.

http://www.jpands.org/vol9no2/blaylock.pdf

I would like to know how Singulair affects the astrocyte numbers and function. I would also like to know if there is a link between metabolism and the cysLT1 receptors in gastro-intestinal mucosa. Does Singulair affect the metabolic process?

So many parents are complaining of ADD/ADHD symptoms? The paper that I gave you the link correlates the immune response and excitotoxicity. That is very interesting. How many asthma and allergy patients also suffer from potential excitotoxicity? Does Singulair cause it in some patients or just make it worse in some patients? None the less--there is a possible link.

One of the most important questions we should be asking as parents is:

How does Singulair - a leukotriene receptor antagonist (blocks the receptors) affect the normal function of the mast cell?

The mast cell is the FRONT LINE DEFENSE against invading micro-organisms. When Singulair was invented, there was limited knowledge regarding the mechanisms by which the mast cell performed it's function. In my opinion, the focus was very narrow - those interested zeroed in on how the leukotriene receptor performed a role in the cause of asthma attacks and how ashma attacks could be prevented. Well, that's good preventing asthma attacks. But what happens to the mast cell if that receptor is blocked on a long term basis. I am not suggesting that blocking the receptor is bad but what if the long term effect is different than what we are are lead to believe-which is this is a safe medication with no known long term effects. What if the leukotriene receptor was just blocked short term a week or two to allow the body to clean up the mess from the last attack?

I seriously question what is going on with all of these infections. Are they related to crippling the mast cell? Parents should be allowed to question. If Merck doesn't want to answer questions regarding what happens to the mast cell (including are the numbers of mast cell decreased on Singulair), then something really BIG is missing. If by any chance (unknown at the moment) that the mast cell is significantly changed and therapy by montelukast is proper on a short but not long term basis, so freakin' what if Singulair is not a huge money maker any more.

Parents deserve every answer possible when decisions regarding their child's growth and development is on the line. I hope that we get some answers.

Of course, what was there in 2002 were new questions-not necessarily answers about the mast cell. Did anybody apply this to Singulair studies?
May 2002

From Journal of Clinical Investigation

Pattern recognition receptors on mast cells
The Toll-like receptors (TLRs) fit the definition of pattern-recognition molecules, which were originally postulated to allow the innate immune system to detect the 'molecular signatures' of various infectious agents. Although the innate immune system has no memory, it shows a degree of specificity, in part because the various TLRs recognize different sets of pathogen-associated molecules. Dermal mast cells are usually associated, not with the innate immune system, but with atopic dermatitis, but Supajatura et al. have found that these cells also express TLRs. They report here that TLR4, which binds the gram-negative product lipopolysaccharide (LPS), and TLR2, which binds peptidoglycan (PGN) from gram-positive organisms like Staphylococcus aureus, induce distinct mast cell responses. Staphylococcus is known to exacerbate allergic dermatitis, but it has generally been thought to act by inducing antibacterial IgE's, which trigger mast cell degranulation by stimulating the IgE receptor. Interestingly, the authors show that the interaction between PGN and TLR2 can provoke mast cell degranulation directly, sidestepping the need for IgE receptor engagement.

I have communicated directly with Leslie Hendeles, a leading professor of pharmacology and pediatrics at the University of Florida who's direct quote to me was:
"In response to your last comment, I thing Singulair has modest efficacy, and if we take all of our patients off this drug, THEY WON'T SUFFER. This is NOT an important drug for pediatric asthma, as are inhaled corticosteroids."

Ironically, this is the same individual who was quoted in an ABC news article as saying:
"We have hundreds of children on Singulair and have never heard parents make complaints about psychiatric side effects. Moreover, there is no mechanism for this reaction … We will be telling our patients not to worry about this."

WAKE UP EVERYONE...THIS IS AN ADMITTEDLY OVERPRESECRIBED DRUG THAT HAS WORKED WELL FOR MANY, BUT HAS ALSO RUINED MANY LIVES.

The manner in which this drug is casually overprescribed by so many doctors is freakish. I firmly believe that this drug has caused countless misdiagnoses such as ADHD, Bipolar disorder and others. IT FUELS A GOOD PART OF THE ECONOMY TO PUT SO MANY PEOPLE ON THESE DRUGS. I BELIEVE THE PHARM INDUSTRY IS VERY CALCULATED IN THIS MANNER.

Question what your doctors tell you.
See my other posts under matthewct1. I dealt with a situation where my 5 yr. old son was on the road to being diagnosed with ADHD which couldn't have been further from the truth. Singulair changed him. Since he's been off Singulair everyone (teachers, pediatrician, family, etc.) unanimously agree that he does not show the ADHD symptoms like he did on Singulair.

While I do agree that research and public awareness of the possible side-effects should be done, there are some of us that take Singulair without negative side-effects. I have been taking it for eight years, since I was 16 and have never had any of these side-effects. There was a couple of months that I did not take it because of financial issues, and the only thing that I noticed was that my asthma and allergies were horribly worse. These were both relieved dramatically when I resumed taking it. Without it, I would spend my days in an allergy/anti-histamine fog not being able to breathe while still taking my inhaler 4+ times a day and several during the night. That is just the beauty and flawed nature of medicine: they work perfectly for some but for others the negative side effects outweigh the benefits. I am sorry that so many have had negative experiences with it themselves or in their family, but please have an objective attitude toward it. Some people need it to live normal lives.

It has been 18 days since my 9 year old daughter has taken Singulair. Our daughter had been taking Singulair for approximately 2 years. It was in the last year that we started to notice some behavior changes and mood swings that were so often unprovoked. We were somewhat concerned and thought like so many other parents that it was a phase. Then in December 2007 she came home from school with a tummy ache and had several episodes of vomiting. She seemed better the following day, but we took her to the pediatrician to be sure that this was a virus. The stomach pains continued, and then anxiety attacks began. Over the next month she began to wake up each day with stomach aches and we began more visits to doctors and more testing. She had abdominal X-rays, CT scan, mekel scan, GI consult and endoscopy. All were ok except she did have some small amounts of acid in her stomach. She was treated with Prevacid with really no significant changes. As weeks passed she missed more and more school, she just could not make it through the day. She had intense separation anxiety, and developed OCD about being sick again and vomiting, fears that she may stop breathing; fear of dying and the list goes on. She was refusing to ride the bus to school, and was having more and more panic attacks that would last for hours. We finally took her to a psychiatrist after we had done every test we could possibly do and all were normal. She woke up with the fear and anxiety, and fell asleep each night the same way. The doctor said she had "OCD" which she believes was triggered by the fear from vomiting. "This was the first time she had vomited since she was an infant.” She was treated with Lexapro, and Klonopin. The symptoms worsened over the next few days even with the new medications. After many calls to the doctor we were finally advised to have her admitted to a children’s psychiatric hospital for closer evaluation where higher doses of medications could be administered. She was there for 4 horrible days with slight improvements. Over the next few weeks the medication did begin to help some and she was able to make it through school each day as long as she was able to call me a few times a day for re-assurance. I thank God each day for her wonderful teacher and staff that have helped us through this. They all have known her for 3 years and knew this was just not her character at all and she was truly struggling. She was always known as "Smiley" to everyone because she always wears a grin. We began therapy with a psychologist as well and she has good and bad days. Then we heard the news about Singulair and I began to trace back other issues she had with focusing in 2nd grade and how things just seemed to progress from there. It all happened so gradually that I would never have put two & two together. She is showing improvements every day with personality, mood, attitude, fears, and the "OCD". She told me today that this was the best day ever!! I have made all the Doctor's involved aware of this information and the progress she has made in the last 2 1/2 weeks. Her doctor did cut her meds in half this week as well. Thanks to everyone that has posted their nightmares as well, and we will pray for you and for full recovery for all those that have suffered.

I hope I'm helping I feel as though I am, too bad I have no idea if the docs will even care or listen But At least I feel good for telling them our story :)

I am repeating one of my post regarding the Swedish study of the side effects of Singulair. When I read that parents have complained to their doctors about side effects and been dismissed, and told to continue the medication, I truly questions whether these doctors are giving their patients the right to INFORMED CONSENT.

I have been told by doctors before something like this "That is my professional opinion - I stand by it ." And I have said right back-- I understand that is your opinion. But if you don't have the time to tell me what I need to know then I am not giving you my informed consent. I get an entirely different attitude after that point. Because, that is how doctors get sued. Parents/patients didn't understand.

1. Have parents been told the complete reasons why it would be absolutely necessary, just necessary, or desirable to take Singulair and why?
2. Have parents been told what the alternative treatments are and the possible side effects of those treatments?
3. Have parents been given an option of another treatment when they complaint about the side effects of Singulair?
4. Do parents know that headache is a side effect that occurs in 18% of patients? These headache have indicated some serious events in European hospital reports. They are not just sinus headaches.
5. Do parents know that Singulair can cause serious events that require hospitalization as referenced in European hospital reports? These reports have described the event and provided laboratory test results that prove that Singulair was the cause.
6. Singulair in NOT an anti-histamine. Can your doctor fully explain to you how Singulair interacts with the receptors on the mast cell (cell part of the immune system)? Can your doctor fully explain how the mast cell will be changed by this? The mast cell has a number of receptors that interact with each other to tell the mast cell how to function normally; when it's time to die; when it's time to be replaced; and when to tell the bone marrow to send a replacement mast cell. Singular CHANGES the immune system---- good or bad???

So here is the report from Sweden to take to your doctors. Would your doctor give consent for his/her children after reading this? Maybe he/she would BUT at the very least that doctor would be looking for side effects that could mean trouble.

------------------------------------------------------------------------------

Update: I have spent hours searching scientific data bases for articles on Singulair. So far this is the most direct reference to adverse drug reactions and Singular.

For anyone who wanted to print the article from the Swedish researchers that stated that their study suggested that montelukast (singulair) should be investigated for adverse psychiatric drug reactions, I was able to find a link with open access to the public. So far, this is the only article that I have found. I am still searching through databases. This link should work if you cut and past. I am sure that all doctors would appreciate the opportunity to read it for themselves to see what they think.

PRINT REPORT.

My son is three and a half and has been taking singulair for a little over two years. But only when his seasonal asthma flares up or when I know it is that time of year that he has problems. While taking singulair he has always complained of headaches, stomach and leg pains, and of course it never occured to me that it could be a perscribed medication. However after hearing the affect it had on another little girl and that leading me to research it to find all of these postings from other parents. What really brought on the investigation is the last week. My sweet little boy turned into a monster. He kicked, hit, screamed, pinched, bit, scratched or anything he could do to physically hurt you. We were all freaked out by this because he is such a sweet, gentle little boy, one of his teachers made every excuse she could think of. Because this was not in his character at all, then of he did it to her. She described it as a switch going off inside him. I believe he was also hallucinating, he told me someone told him to do it. This is by far the most scary thing I have ever been through and will never give my son singulair again. Further more I am going to pass this information along to all my friends and family and hope and pray that it makes is to everyone so this madness this perscription medication causes.

My 6 year old son has been on Singulair for 2 years and I have noticed a big change in his behavior but it all started with leg cramps and falling down alot..I told my dr about what was going on but she told me that it was nothing to worry about that it is growing pains..Before he started the on the singulair he was always a happy go lucky kid never had problems with him back talking or ever really getting angry. Now that I read all these reports these are the problems I have with him now:
My child has never offered to hit, kick or slap me but in the past year he has gotten more aggressive not only toward me but others as well..
He is fearful of people now thinking that they are being mean to him or picking him out to pick on or make fun of.
He has problems of headaches on a regular basis but just thought it was due to his sinus infections...
I have also noticed that my child has started hurting himself like punching even slapping himself in the face when he gets really angery or fustrated about things..
Sometimes he has problems with nightmares but not that much..
He also has problems with stomach pain as well...
My concern is taking my son off Singulair with his asthma being under control right now and he just recently had sinus surgery but I think it will be the best thing for him just because I want my sweet child back not the aggressive and abusive child he is now.... That is why first thing in the morning he will be taking him to his dr to find another medication to put him on and take him off the Singulair....

Follow up to my post earlier today...

I took the my son to the doctor this morning and he was somewhat dismissive of the recent reports on Singulair...says he's had a lot of kids on the drug and never heard a peep about side effects until last week when the report on suicidal tendencies showed up. He did advise that when these kinds of behavior changes happen after a new drug is started he would recommend that we stop taking the drug no matter what it was, but I still felt uncomfortable with his response to us.

I felt like he was accusing me of making it up or only coming up with it because of recent news and message board posts. In fact, I made the appointment BEFORE I saw the posts. I was worried about his behavior BEFORE I saw the posts. It's just that seeing the stories from everyone else basically confirmed my suspicions that it might be the drug causing the problems.

I feel like I definitely wasted OVER AN HOUR waiting for a doctor to spend five minutes making me feel small.

Last night was the last time my son will take the drug, and I don't care what the doctors think of me.

I noticed a lot of postings about weight gain on Singulair, which is nowhere listed by Merck as a possible side effect. My 15 y.o. daughter experienced sudden weight gain at the age of 9 when she was actually underweight (BMI went from 17 to 21). To make a long story short, after being off Singulair for over a year, she is now over-weight, and diet/exercise have never made a big difference (gymnastics, swim team, figure skating, trampoline, etc.) Extensive labwork is always normal & there is no family history of obesity. It's a shame the quality of life of a child is RUINED by a drug that is deemed to have "no side effects", and the many drs. & specialists out there take it very lightly. We continually worry about our daughter's self-esteem, risk of diabetes, and other complications from weight gain which is not hereditary and goes on unexplained by the drug co. Reversing this weight gain has been nearly impossible. Everytime I hear a news report about our children being overweight and obese, it makes me angry because I think about the many kids that are taking this highly prescribed drug (for even the mildest allergy or asthma) and who knows how many parents don't make the connection!

My daughter had an appointment with a gastrointestinal doctor this morning because of her stomach problems. (She has been off of Singulair 10 days now and ALL symptoms- leg pains, abdominal pain, dizziness, sensitivity to light, severe mood swings, depression, anxiety, severe tantrums have all vanished) We kept the appointment with GI because our physician advised us to. He found it hard to believe that Singulair could be the cause of all of her symptoms. Well the GI also found it hard to believe that Singulair was the cause but said, "The proof is in the pudding." I have filed a complaint with the FDA on medwatch.com. It was very easy. I have also asked the doctor to file one as well. I also gave the doctor a printout of the studies done. Hopefully with more and more people filing complaints the FDA will act quickly. There is so much indisputable evidence regarding adverse reactions. It is unbelievable how many stories sound just alike. So many children have lost years of their life due to this drug. Parents have spent so much time and money trying to figure out what is "wrong" with their child. It is a shame so many have been incorrectly labeled all because of a drug they were taking!!

I was given the fantastic news that my body doesn't like itself anymore. I don't know when it had a falling out, but all I can say is the course of action to remedy this disease is CRAZY. Taking meds that have more side effects and the restrictions on my daily life, because of the meds, no driving, no salt, no sugar, and little fat in my diet, very little sun.
