Singulair and adhd

Hi Everyone after reading all the posts and crazy medications everyone esp. kids and babies are taking I would suggest reading this book. It is called Healing the New Childlhood Epidemics and is quite interesting.
Written in 2007 by Kenneth Bock M.D. and Cameron Stauth it goes in depth the causes and healing of autism, ADHD, asthma and allergies. It is quite interesting as the causes of all four are similar and related. I am still reading it as my son just had ear tubes put in and always seems to be having sinus infections. Dr. Bock seems to have had amazing success by targeting detoxification, removing sources of inflammation, changing diet, etc. and transforming kids back into a healthier state. Hope it helps you.

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.

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!!

Hi,
My 5 year old son has been having similar problems. He was on Singulair on and off since 2006, throughout winter for his asthma and sporadically in the summer. His new pediatrician finally said to keep him on it everyday the beginning of 2009. The only reason I am here today is because I just filled a new prescription of Singulair and low and behold it had a new warning label none of the other bottles had, "Call Dr. if you experience mood changes, sadness, depression or fear." I quickly went online to read some reviews, to my horror I see hundreds of posts from other parents detailing my sons exact aggression/fear issues.

I have been having so many many problems at his school. I had to take him out of first Kindergarten because he hit the teacher a few times. In the new school he was doing ok but then it got worse, then better, then worse, then better again and so on. Maybe it was the breaks of singulair he would get. I had him meet with THREE different therapists for ADHD and they refused to conduct any further evaluations on him because they couldn't find what the problem was. The school even ordered an educational evaluation for him to see if there was a learning disability.

The teacher is always complaining that he's too distracted, doesn't sit still and is so aggressive. He is meeting all his benchmarks and is very bright but his social behavior is causing mayhem. At home his fear of things got out of control. He was scared of his lamp and would wake up screaming at the top of his lungs full of panic and fear because of the stupid lamp. He won't go to the restroom by himself because he's scared a monster would attack him etc. Since I started giving him the medication consistently everyday everything just got worse. He flips out at home, pushes hits and is snotty as all hell.

It makes me sad because I swear he tells me the same thing, "But mom I was trying so hard to be good and I couldn't. I was telling my brain to stop but it wouldn't listen. I don't know what happened." He would come home so sad, frustrated and upset. He had a few bouts of crying in the classroom too, lots of problems with aggression.

I've done the same thing, time outs, reward system, even made up "Jacob days" which were days we did whatever he wanted at home if he had a good week at school. NOTHING works..... I was at a loss until I read these reviews.

I am taking him off tonight and hope this is the end of all the aggression or at least helps a bit. I'm not going to say my son is 100%angel but he used to be much sweeter, calmer understanding and so on. I would just be happy if it helped a little. It's a shame because this medicine was helping with his asthma but at what cost. I will post an update and let you all know how it's going.

Oh I forgot to mention he has been in and out of the school nurses office this past month for stomach aches... he had a lot of stomach problems at home too. So I will see if that clears up too.

I have been on Singulair longer than I can recall... at least 10 years, maybe longer. My 7 year old son has been on it since he was probably 12 months old. Neither one of us have had any problem reported here. No depression, no sleeplessness (until I weaned him from naps, he slept up to 13 hours a day), no leg cramps, nothing. We are two of the happiest, most well adjusted people you could know. And, best of all, we haven't had any asthma attacks. Bottom line, different drugs react differently in different people. Don't let the post here stop you from trying a medication that for some could mean the difference between life and death depending on how asthmatic they are. As with any drug recommended by your doctor, try it. If you experience adverse reactions, stop it ASAP. It's that simple.

My son is 8 and for the past 3 years has been on Singular for seasonal allergies. He has since been diagnose with asthma and he takes Singular daily. After being on it for 3 weeks he is now getting into trouble in school. The teachers say it was like a light switch being turned on. Completely out of character behavior. My question is this......has anyone experienced hyperactivity behavior on Singular?

I have a grandson who is on singulair since he would walk. He is now 5 years old. He has trouble in school, heat racing, out of control tantrums, biting and hiting in daycare. When he is not taking this medicine he is a different child. Parents are doing what ever the physicians order. Please stop prescribing medicines just for a runny nose, it is not worth the side effects.

the pediatrician prescribed singular for my dd when she was 12yrs old for her asthma. she described it as being safe. that same year dd started having problems in school and seemed depressed. I talked to the doctor about it thinking maybe it had something to do with her adhd medication. the doctor thought maybe it was just normal teen behavior and dd trying to adjust. eventually we took dd to a therapist and things seemed to get a little better. then dd started complaining about stomach pains, she talked about strange dreams at night and would wake up in the middle of the night. Then the tantrums started, wild out of control tantrums. she would scream, throw things, destroy things, she talked about wanting to die, how she hated her life. again I went back to the doctor her adhd medication was adjusted and I also got her back into therapy. therapy was helpful but we continued to deal with the wild tantrums. we kept trying to seek help and answers but to no avail. we were beginning to think dd was suffering from a mental illness. the doctor told us to keep an eye on it and the next step would be maybe putting her on more medication. In the meantime dd became anxious, she had an anxiety attack at school, she would get in arguments with her friends and become very irrational, she continued to be angry at home, she destroyed things in her room and punched a hole in the wall. When I would look in her eye she had the look of a wild animal. my doctor began to think it was merely teen rebellion and we needed to get tougher with her. Never did it ever cross my mind that it could be something with singular till I heard about the study on the news then it all clicked. before singular my dd was an above average student who was liked by teachers and students alike. teachers talked about how well behaved she was and she was a leader. she was very active in various activities at school. Now she has become nervous and suffers from anxiety attacks, she has out of control tantrums and anger. her friends frequently avoid her or her calls because she has become so moody and angry. she frequently complains that her stomach hurts and feels like she's going to be sick. she screams and talks about wanting to die and that we don't love her. till today I had considered this drug to be safe and very useful in controlling her asthma but after doing more research i'm beginning to wonder if it's worth the risk.

My son is 11 years old. He has been on Singulair for about six years. Ihave taken him to see a psychologist twice because of his terrible mood swings. He was diagnosed with depression last year. I am very concerned about this drug now. He has also suffered from migraines for two years. I also pulled him out of school and started homeschooling him because of the stress of school was causing three migraines a month. I also have a 19 year old boy who is not on singulair now. He took it for 8 years and was diagnosed with ADHD. He also went through depression as a child. I am making a appointment for my son to go back to his allergy doc tomorrow. Also I am not blaming my sons illness on singulair, but I am terrible concerned that it could have harmed my sons.

I would like to know who is NOT experiencing side effects from Singulair.
We are not.
My 7 years old started Singulair three months ago because of allergy issues. She had asthma attack every other week, running nose all the time, she was so miserable, she missed many days of school and she couldn't exercise .Since she started to take SIngulair her allergy improved, no more asthma, no more running nose. SIngulair did not change her way to be. She is doing very good in school (she is above the average..) she does piano, ice skating, she is purple belt Tae Know Doe, speak two languages, she is doing great in everything. Of course she has her "bad moments" but which child does not?
I tried homeopathy, but it did not work, she got worst and worst. I was supposed to give SIngulair to my daughter a year ago, I did not because I was afraid of the side effects. But I wished I had started before because I could have avoid so much steroids since she had asthma most of the time. The doctor convinced me to use this medicine when she said " You think SIngulair has side effects, yes sometime it does, but do you know the danger of using steroids so frequently in a little body?" Then I thought I had to give a try. I am glad I did. Of course I keep watching my daughter behavior closely and reading all the possible side effects of this medication. I forgot to say that beside singulair my daughter is also taking Pulmicort, two puffs once a day.

We have a 5 year old daughter who has been on singulair for about 2 - 3 years. She went on singulair due to coughing asthma. We were soo happy about how well the medication worked, it took about three months, but wow, she finally got over her coughing and was living a more active life. I actually was soo impressed with it, I remember mentioning it and promoting it to some of our daughters friends' parents with children in similar situations....wow do I ever feel awful. Anyway, our daughter came down with a terrible flu a few weeks ago and although she didn't seem feverish, had not one, but 2 night terrors, something that we have been worried about and comforting her with for a couple of years. These 2 threw the 2 of us over the edge this time....we thought we had to get her to a psychologist.....she was terrified, and although we were holding her and comforting her, she was still screaming for us, and there was NOTHING we could do this time....we were doubting ourselves and the environments she was exposed to......what could have happened in her life to make her have such awful dreams??? It was about a 1/2 hour later when my husband asked about the possible side effects of the singulair.....I ran and grabbed the pamphlet, of course this is the first time that I actually sat down and read it, which I should have done some time ago....anyway it was then that I discovered how many issues weren't normal that everyone just kept ensuring us was fine. We had been questioning ADHD for some time, and had actually had it on our list to discuss with her teacher as she was sooo hyper on a regular basis...at the age of 5 she still couldn't sit through a movie at a movie theater, as much as she loved going, she couldn't sit through it....anyway, the only thing that made it difficult to think she could have ADHD was she was such a great learner. She was very eager to learn and loved learning and teaching things. But when giving her instructions or asking her to listen, she'd be so jumpy. She complained of severe leg pains which we chalked up to growing pains...poor thing! Her temper tantrums were out of this world.....she is a child that is soo full of love, but when she was in tantrum mode, she was soo destructive and she would feel soooooo awful for her actions, it was like she couldn't control herself. We just feel awful that we couldn't help her and we didn't realize that what she was experiencing was not so much disobedience, but an imbalance due to the medication. We have since taken her off the singulair, we took her off of it immediately following reading the pamphlet. We found that she was VERY emotional for about 3 days, then she pretty well recovered. She has since become a normally active 5 year old, she is soo good, and has not experienced any night terrors, complained of leg pains, and absolutely no tantrums. Oooh how we love her so much.

My 7-1/2-year-old son was on Singulair for 5 months for asthma and possible allergies. He had been on medication for ADHD for almost a year at that point and had been doing well with it. Singulair made him into a monster. He could not be reasoned with and was constantly overreacting to everything. Just asking him to put on his shoes caused explosive reactions, even to the point of threatening us (his parents) with bodily harm if he did not get his way. We unexpectedly stayed the night out of town and did not give him his Singulair for a few days and started noticing that he was much more rational, calm, and more like his old self. I had heard of the depression risk with Singulair and googled about it this morning and was floored by the amount of children with these type reactions. It is now listed as an allergy for my son and I will never give it to him again.

I posted serveral weeks ago about taking my 5 1/2 yr old off singulair. He has done great as far as the asthma, no problems what so ever. The main reason I took him off was due to his behavior. Very moody, hyper, aggitates easily and so on. Well, after the 2nd week, he was like a NEW child...very calm and behaving in school. Well, he has pretty much regressed back to the behavior before taking him off this med. He has now been off of it for 5 weeks. His teacher asked me last week, if I had to put him back on this med, because he was getting back to his old ways.
He is currently going the an evaluation for ADHD. I have stuggled with the fact that my son may suffer from this and have tried almost everything to avoid medicating him...I was really hoping this was the culprit to his behavior..He had been on singulair for over 4yrs...Is it just going to take longer to see the full effect of NO SINGULAIR???

My ADOPTED son almost 6 and was already on Singulair when he came to live with us at age 20mos.
After finding this site just over 2 weeks ago, I took him off on this stuff. Well, after about a week, things were so good that it was scary. His behavior improved so much, that everyone said he doesn't act like Jacob. I said, yes he does, we just didn't know him before going on this med.
He is currently going thru ADHD evaluation and I advised the therapist that I took him off this drug and he was like a new child. Her comment was "did we cure him"? Well, after her one on one with him, she commented, I don't know whats wrong, but he is extremely HYPER and then all hell broke loose on the way home. But, he has been fine since.
I am praying that I don't have to medicate him for ADHD, I am just not ready for that and have been fighting it for a while and then after reading all the side effects on this site, it described my child to a tee. He is in Kindergarten and is doing great academically and the therapist was a bit surprised by that with how hyer he is.
Please tell me with how long my son has been on this drug, that it's going take more than a couple of weeks. He is not near as hyper to us as he was before. Maybe he just got excited about all the toys in her office. He can also be very defiant, that is whole other issue we are dealing with. He does way better for his Dad than Me, so now if he doesn't want to listen to me, he Dad intervenes. I am hoping he will get it, that he can't be disrespectful to his Mom or he will have his Dad to deal with.
Thanks for listening and please pray that his behavior will continue to improve over the next few weeks with the absence of Singulair.

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

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

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

I was put on Singulair about three weeks ago, and noticed immediately that my mood had changed. I am an adult ,and felt this sense of sadness, anxiety, solitude, not wanting to be around anyone. I took myself off the drug and have tics all over my body and eyelids ,which is driving me crazy! I even had heart palpitations ,which are very distressing. Today it seems to be better, and this is day three off the med. The only way I can explain how I felt on this drug is doom and gloom.

My son is almost 4 but has been on Singulair since he turned 3. We saw an immediate improvement in his allergies and asthma and thought it was a miracle drug. That is until we started to see our sweet, outgoing little boy change into something we barely recognized. We thought maybe it was just a stage he was going through or something and didn't connect it to the Singulair until his doctor accidentally wrote his refill prescription for 5 mg. instead of 4 mg. After about 2 weeks on the 5 mg. his mood swings increased substantially. He cried for hours everyday at school. He had previous trouble with his emotions at school on the 4 mg. as well. He continued to cry and throw fits at his preschool so often that he was ending up in the principals office. At home, he became clingy and so emotional that he would cry about everything. After doing some research on Singulair, I immediately took him off the drug. Within 1 1/2 weeks off of the drug, my little boy was a different child. I thought maybe I was the only one who had noticed until his teacher came to the car and ask what happened. She said that he didn't even resemble the same child that started school. He is sweet, and calm. He can take discipline without crying and gets praise every day instead of going to the principals office. His trouble sitting still and listening to the teacher are gone and her push for us to have him tested for ADHD has ended. He is now a star student. The only difference is the removal of Singulair from his little body.

i'm glad that i found this site...thank you.
I have a seven year old boy and a four year old girl that have both been on singulair for a couple of years. The first year their allergies weren't that bad, so i didn't really make sure that they took it daily...the past year, allergies have been worse, so i was making sure that they took it daily and that they didn't miss a dose. My son was in 1st grade last year and by the end of fall, he was going to the nurses office daily for headaches and stomachs. Where his drawings used to be of flowers and all of us as a family, they started being of monsters. We also noticed that his pupils were dilated more than normal (you could barely see any of the colored part of his eyes) and took him to an eye doctor just to find out that his eyes were fine and there was no medical reason for the dilation. I also asked the doctor and the school to test for ADD/ADHD, with them saying that he didn't have it..At night, both my son and daughter started waking up for no apparent reason (they had both slept through the night since they were about 1) and being very scared for no reason. The mood changes have been more noticeable in my son, but like most, i chalked it up to "a phase" and just part of being a boy....my daughter got clingier and moodier, but i know how it is to be a girl, so i just took it with a grain of salt. My kids have not been on Singulair for approx. a week now, and my son is back to the boy i knew....skipping through the house and yard, catching bugs to just look at them and not pull them apart and kill them, sleeping through the night, no trips to the nurses, and eyes that seem to be normal again...my daughter is actually a pleasant little girl that can't wait til she see's her brother instead of pinching, hitting, and trying to hurt her brother........Long story short, since they've been off of singulair, i have my kids back. my son had circles under his eyes at times and a runny nose at times and we have to find something to help my daughters allergies (she gets eczema and is borderline asthmatic) but we will deal with that and find something that works without harming them.....
Thanks again.

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

I have been reading a book on anxiety and phobias,it says that the Gene # 23 is shorter for people pre dispositioned for anxiety,If this is the case it makes sense as this drug works genetically,,so i wonder the % of short 23 to long 23, and that would give Merck its % of adverse side effects...betting its more than they are saying.As far as the doctors still saying this is a small %,they are just not asking the right questions,The insurance companies should have a record on clients that filled prescriptions for singulair and anti depressants and adhd drugs.If we all cn figure it out in a week ,Well what does that say

This is so scary!! I was just looking up "my son says he hates himself" on google, because I was concerned, as I deal with depression and wanted to find out if a little boy saying this (6 yo) is normal or if it may be signs of depression. Weirdly this link for singular came up.
My son DOES take singular for his asthma and has been taking it for about a year on and off. I have tried to take him off because I hate feeling like a pill pusher, but then his asthma flairs up again. So I put him back on it.
But today he has just been whining and crying (he is still crying and screaming for me loudly now!) and I began to get VERY concerned that my son was exhibiting signs of depression. If this is true, we may need to file a lawsuit against the drug companies as there are too many similarities and coincidences with this singulair. It wasn't even a THOUGHT or consideration that the medicine could have been causing this. I just thought that he was growing up and just goind through stages. Now I feel stuck because I don't know whether I should take him off and risk his asthma flaring up, or keep him on and risk his depression gene flaring up. This is VERY scary....

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

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

My eight year old son, who has asthma and has been taking Singulair since he was three, has been off Singulair for four days and is becoming a completely different little boy! He has always been a "difficult child" with intense emotional reactions to things, anxiety, oppositional behavior, a short fuse and bad temper. He has also displayed obsessive/compulsive behavior. His father and I never thought that his behaviors and symptoms were caused by Singulair. His pediatrician never suggested it. With a family history of anxiety, we just assumed it was the way he was. At four, his preschool requested he be tested for ADHD. The testing revealed a short attention span but not a diagnosis of ADHD. As he got older his symptoms grew more intense. Last year we considered taking him to a psychiatrist but decided to "wait it out" one more year to see if maturity would bring an end to some of the behaviors. It didn't and in fact they grew worse. He became aggressive, explosive and depressed.

I recently began taking Singulair for another medical condition and had noticed that it made me a little moody. Last week, on the verge of making an appointment for my son with a psychiatrist, I started to wonder if maybe he was reacting in a similar, yet more intense way to the Singulair. I reviewed the patient information on line (I had read the patient info for Singulair when my son started taking it, but had not done so in years. I learned a tough lesson: check the information that accompanies prescriptions each and every time I get a refill.) When I read what the "less common side effects" were I was convinced that my son was reacting to his medicine. Then I found this website. We stopped his Singulair immediately and within two days began seeing a dramatic change in our son. He was less high strung, defiant, and explosive. Yesterday we had a cookout with some friends and he played with other kids all day without fighting for the first time in his life! He even cooperated when we asked him to help us get ready for company.

I strongly believe that this medicine should not be given to children and teens. I am so upset that when I asked my son's pediatricians about his behavior TWICE last year, they never mentioned that Singulair could be the problem. I called today to tell them he wasn't taking it anymore and the nurse said that she would note that he is "allergic" to it in his chart!

We are exploring alternate and natural ways to treat our son's asthma. I will NEVER give him Singulair again!

FYI: the labeling for his albuterol inhaler states that "safety and efficacy have not been established in patients under 12 years old". His pediatrician has been prescribing albuterol inhalers since he was three!

Does anyone have information about herbal inhalers and naturopathic treatment of asthma? If so I would like to hear.

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

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

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

My son, who just turned 14 this month, was on Singulair for over 2 years.
He was diagnosed with reactive airway disease and possibly Asthma--and prescribed this awful drug-even back in 2004. The doctor said how wonderful this med was and prevents any further attacks.. So, for 2 years-every night, he took this mood altering, destructive drug. He lost all interest in school, his athletics-soccer, skateboarding, biking..in fact became almost a vacant , very unhappy, child-had stomach aches, joint pains and reflux--why--I brought him to the doctor and Pediatric center so frequently--all they kept saying his --his asthma is better, much be other issues...Even after the March 2008 suicide--his doctor said-that is just an isolated incident-just monitor him--It is a good drug. Right, month by month his behavior escalated to wanting to die, no reason to go to school-he said he was stupid and a failure and why don't I understand there is no reason to his life. A usually happy fun-loving boy -my son- didn't want to live. Nothing made him happy-I started to believe what the doctors said--maybe something or someone at school (bully, pedophile??) caused this change. Terrible nightmares and vivid dreams...Until this past July, I asked him want to go to the library for some books or dvd's...he went ballistic-threw everything off his computer desk and tried to break his chair. He is not an aggressive boy but this behavior was becoming a daily issue. Along with everything flying off his table, was his bottle of Singulair pills. It then dawned on me..I have been poisoning my only son. The child I know and love and gave birth to returned within a few days--although I am worried sick about further asthma attacks --all the doctors can prescribe is a steroid drug-asthmex or Pulmicort.. I cannot understand nor comprehend why this drug is being prescribed for children and young adults. The guilt I live with is terrible as my son has lost 2 years of his life--
and thought there was something really wrong with him-At least we woke up---in time--how about some other parents..thinking it's just normal adolescent behavior for their child or their fault???

I took my son off the end of March & come back once in awhile to read & I'm blown away by all the stories that I still keep reading :(

I just told his GI doc today that this might sound crazy.. but I have reason to believe that Singulair was making my son's reflux worse because now he only needs halk of his reflux med & is doing fine

My son like so many others on here had every side affect listed & it took almost a year to figure it all out He still has ADHD & other issues which I already knew about but all the stuff that was happening while he was on singulair Has Stopped!!!

GL to everyone I try to spread the word about this drug as much as I can

I'm a mother of a lovely 6 year old child who has been on Singulair for four years. For four years, I've dreaded taking my child anywhere public for fear of her outbursts and for four years, I've thought that Kate perhaps has ADHD. Funny, but she had near psychotic reactions to the inhaled Albuterol the docs put her on due to some very scary episodes she had before the age of 2 with RSV. I never suspected that the Singulair they put her on for Ashthma might be the cause of the behaviors that she and our family have suffered with for years. I've called her doctor and told the doctor that I'm taking her off right now, IMMEDIATELY. I've even consulted with the doctor about her behavior but got the feeling that she just thought I was being oversensitive. For four years, I have had a hyperactive, moody, sleepless and generally unpleasant child and I am worn out and heartbroken. I pray that taking her off this medication will work.

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!!

My 7 year old daughter has been on Singulair since she was about 2 yrs.old. She has always been very energetic child, but I did notice as soon as she got a little older she began to get very aggressive, angry and mean all of the time. She also has had trouble making and keeping friends because she is so hyper and emotional. I never even associated Singulair with her problems until recently, even though I was told a few months ago that Singulair could be the problem. So, back at the beginning of June, my husband and I kept forgetting to give our daughter her Singulair, and this went on for about 2 months (and her mood was improving immensly). Feeling bad that we kept forgetting her Singulair, (not realizing that that was the problem) we started her back on Singulair again just a about a week ago and in just a few days time she has been truly unbearable! She's been very mean, yelling, throwing things, totally unruly! So bad that I was going to have her completely tested for ADHD and whatever else! So as of today, I am taking her off of Singulair and I am contacting her doctor first thing in the morning! Good luck to all!

Hi to all,
I wanted to take a minute to say Thanks to all who post and search for answers to this drugs confusing and serious side effects.To all who have taken the time to contact the FDA and file a report to help others.Dr.Sarah Sellers is no longer the person to contact at the FDA,she has moved on after concluding her end of the investigation on Singulair.If you have a serious side effect please still take the time to file on the official FDA site for adverse event reporting.In NY. state we are still searching for legislation to help with the notification process for these serious side effects.There are to many Doctors that still do not have a clear idea of the updated side effects,and are not reporting as they should.
Letting your doctor know that good medicine is all about follow up on complaints,such as researching the singulair website to rule out that it may be the drug or it may not.Just dismissing the patient and prescribing another drug is how these drugs go undetected for so long.We want this to stop and only the unfortunate recipients of the horrors of this drug can make this happen.Again thank you for your efforts to change the system with follow through and perserverance.Our horror story is one of many and we want to help those who have survived the ravages of this drug, OUR CHILD DID NOT. Kate and Dave M.

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.

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 began taking singulair when he was 6. About that time we were hading into the school years. He was labeled as a "special" child from that time on. Impulsive, aggressive, angry, anti-social, etc. He had a hard time focusing at school and every day was a battle. About 5th grade, after 3 schools, he was diagnosed with ADHD. I never, ever thought that it could be this medication. He was on it for about 4 years off and on during allergy season. I transferred him to a private school for children with behavioral issues and as time went on through therapy and special schooling it seemed to get better. I look back now and see that our "good" times were when he finally went off it for good. The beginning of his Freshman year was great! He had a 3.58 GPA, making friends and finally happy. The unfortunate thing is now that puberty has really kicked in, we are back to the old behaviors but much worse. Impulsive, angry, anxious, afraid of the dark, afraid of death. Violent thoughts, impulsive and very unhappy. I can see now that my son never had ADHD. He was misdiagnosed because thier were no warnings at that time. I don't think it ever "goes away". Even after years of being off of it. Something with the puberty hormones is re-triggering this behavior. IT IS LONG TERM!!!!! Even after discontinued use. Please, please keep an eye on your children. I AM SO ANGRY FOR HIM!! Also, for me. Special school $400 month, psychologist appointments, $300 month, my poor Son in a dark place I can't get him out, PRICELESS. . .I want my Son just to be happy. Thank you all for sharing your stories, it gives me strength that I need for him.

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

Update. The count down is on. Next week on Tues my 6yr old son will be having his tonsils removed. Only 5 months after the adenoids were removed. I am hoping once this is over the improvements I have seen will just get better! His sinus drained in April, 9 days after coming off Singulair after battling sinus infections for entire year or more actually. When his sinus drained the infection went right into the tonsils and he has had tonsillitis ever since. One thing I wanted to share is that around the same time he came off singulair we started omega 3 supplement. Both my son and I stopped Singulair the same day. We both started the Omega 3. Last week I had to stop his dose because of the upcoming surgery because it can thin the blood. I noticed this last week his nasal allergies kicked in. He did pretty good through this allergy season and wasn't on any meds a lot of the days. I hardly had to take allergy meds this time around also. Im allergic to trees/grass and this is usually my bad time. I really feel the omega 3 has helped a lot!!! I am also waiting to get the results of his blood tests to see if his cholesterol has gone down. Just wanted to share!

Hi,
I wanted to post this link just to give some small consolation to our concerns about the lack of awareness THAT DOCTORS HAVE ABOUT SINGULAIR.This is a voluntary online informational site,that doctor's can join. It provides updated information on serious label changes and safety concerns on drugs.Most doctors at this point still get snail mail updates,in the paper shuffle a lot of information gets misplaced.The AMA would like to have all information come in online,eventually.The link is ******
read it and tell me if you think more can be done By the way my pediatricians office does not have online communication.Our life is forever changed because of that ! Information is playing a vital role in this drugs destructive path ,or the lack there of information.Again this is voluntary for the Doctors to sign up .In this modern day of communication how does important information not get where it is the most useful, I ask you?When drugs are making multi billion dollar profits,that would be an educated guess.I am doing another interview with CBS affiliate out of Boston on the 23rd of June,they contacted me.I hope it will reach more people who are still unaware of this drugs serious potential side effects.If any of you parents have some connection to media ,please use it to your best advantage to get this very important information out to the publicAlso so many of you ask how to help.Contact your local Senators and keep bothering them to reach out to the FDA to expedite this investigation. Make a pain in the butt out of yourself and be persistent.I will try to make reference to this site so your stories are heard. Dave and I are coming up on a year since our son passed on to our lord .Still fighting Kate and Dave M.

Many people have asked why I suggested that Omega-3 from fish oil MIGHT possibly help those retrying to recuperate from the adverse side effects of Singulair. It is my opinion, that it MIGHT help the body return to balance. And unless we OD on Omega-3 from dietary sources, (avoid tuna fish high in mercury), then it won't hurt.

"When cells are activated by external stimuli, arachidonic acid is released from cell membranes and is transformed into powerful cellular mediators such as thromboxanes, prostaglandins and leukotrienes.10 These compounds possess a range of activities, including activation of leukocytes and platelets, regulation of gastric secretions, induction of bronchoconstriction and signaling of pain in nerve cells. The importance of these compounds in health and disease is evident by the range of pharmaceutical products that target their biosynthesis or action.11 Indeed, arachidonic acid metabolism is the target of nonsteroidal anti-inflammatory drugs (e.g., acetylsalicylic acid, ibuprofen), cyclooxygenase-2 (COX-2) inhibitors (e.g., rofecoxib, celecoxib12) and leukotriene antagonists (e.g., montelukast, zafirlukast).13 Dietary omega-3 fatty acids directly affect arachidonic acid metabolism because they displace arachidonic acid from membranes and compete with arachidonic acid for the enzymes that catalyze the biosynthesis of thromboxanes, prostaglandins and leukotrienes.8 Thus, the net effect of consuming foods enriched in omega-3 fatty acids is a diminished potential for cells like monocytes, neutrophils and eosinophils to synthesize these powerful arachidonic acid–derived mediators of inflammation and a diminished potential for platelets to produce the prothrombotic agent thromboxane A2." (Surette, 2008).

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.

I've noticed that NBC and The Weather Channel appear to be two of the biggest advertisers of Singulair. NBC can always be sure to have one on during the evening news, at least here where we live, on our local NBC channel. There for awhile, I was logging what time, and what channel I saw the ad. The ad only lists the basic side effects that aren't even dangerous. Merck must be paying NBC the big bucks because they still haven't dropped it. I don't know, should we bombard NBC with letters of negativity or boycott or something to get their attention on this murderous drug?

I have a three year old son who has severe allergies. He's been taking singulair for 2 years on & off just in the allergy season. He started taking, singulair again in the beginning of April. One morning he woke up and both eyes were really swollen and red, I called his doctor's office and told them i thought he had pink eye, after 2 different drops and no change I brought him into the doctor's to see if it could be his allergies, and they agreed and started him on Zyrtec. I still was not impressed with the results so i brought him back yet again to see if we could see a specialist. Instead they put him on nasonex to try.
In the beginning of March I started to see a change in my usual happy fun loving son. He was scared to sleep in his bed, waking up in the middle of the night from bad dreams, uncontrollable screaming fits that would last up to an hour, saying he wants a Boo Boo. At first we thought it could be jealously over his new brother, or maybe something at his school.
Then i found this website and everything clicked, how scary it must be for a child to have these horrible thoughts and not be able to understand or stop them. What are the people at merck thinking??
Can any one tell me when the symptoms stop. He's been off for a week and we see some improvements. But he still has these fits with almost an OCD tendency to them (mainly when he's overtired), stomach pains, lack of appetite.

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?

My 6 year old daughter Started taking Concerta about 3 months ago. Some things I've noticed are, loss of appetite and loss of weight.
She has had very noticeable academic improvement at school. She is concentrating better. At home I l see how she can go through mood swings and emotional episodes. She snaps all of the sudden and cries if things don't go as she expects. I'm not sure why this is happening. She is currently on the 36 mg. I really don't like having her on this or any other medication. It's very frustrating trying to decide what is best for your child.
She is also taking Singulair for her asthma and allergy symptoms. I was reading the reviews Singulair medication and they are scary! I don't know if her emotional episodes have to do anything with singulair or concerta med side effects. For now I'm definitely taking her off Singulair and see what happens.

I have two sons on Singulair, my three old was suspended today from pre-school for bad behavior. Screaming, biting, scratching, and hitting have been going on for the last few months. But worse the past two weeks. He has always been active and played like a boy, but he has been getting violent. We have tried positive reinforcement, praising good behavior both verbally and with rewards, I have tried time-out, being grounded, not being able to participate in activities, no t.v. and old fashioned butt spanking. All of this with no positive results. I am not looking for an excuse for my child's behavior, but could Singulair really be the cause of his aggression?

Unfortunately my lawyer told me that they do not want to take our case because of the lack of evidence that Singulair has caused our daughters problems. :(

Does anyone out there have a pending class action lawsuit that We may be able to get in on? I have tons of proof that Singulair has caused our daughters problems and loss of almost 5 years of her elementary school career!

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.

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.

Why the brain function is impaired due to Singulair????? Maybe.

Here is the last chapter in a theoretical reason why Singulair affects brain function thus causing anxiety, depression, agitation, aggression, ADD/ADHD, and in extreme situations maybe seizures. I presented the study of the Chinese researchers that show a direct link between the cysLT1 receptor and the astrocyte in the brain. We don't really know how the cysLT1 receptor interacts with receptors that control astrocytes under all circumstances. We just know that there is an important link.

So last night, I had a dream about astrocytes. I don't really have anything to do but sit on an island, look at the Caribbean and fish so mental stimulation is actually welcome.

The last part of the "chain reaction" is probably the astrocytes role in glyconeogenesis. In other words, when the brain does not get proper nutrition, it sends signals to the liver to do something about the problem. The liver in turn releases glycogen which is turned into glucose to be released into the blood stream. A very unhappy brain becomes a very relieved brain. Obviously, we can't be eating all day long to keep our blood sugar up so the liver has to store energy and release it at the correct time.

Here is a diagram of that. Astrocytes are the only cell that produce the proper chemicals for this process to happen.

Glucose utilization pathways that provide or consume ATP. (A) Schematic of key aspects of the glycolytic pathway of glucose utilization for energy metabolism and major branch points that can divert carbon for other uses, including NADPH generation, storage of glucosyl units in glycogen, neuromodulator, and amino acid and nucleotide biosynthesis. The most important reactions for generation of energy are glycolysis (pyruvate/lactate formation from glucose), shown in light brown and occurring in all cell types, and glycogenolysis (pyruvate/lactate formation from glycogen), shown in light green, which occurs only in astrocytes, due to the astrocyte-specific expression of the enzyme glycogen phosphorylase, which releases a glucosyl unit from glycogen as G1P. The energetically most important biosynthetic reactions are synthesis of glycogen from glucose (glycogenesis) shown in brown and green and from pyruvate/lactate (gluconeogenesis) shown in pink, brown, and green. Gluconeogenesis is also astrocyte-specific, because only astrocytes express fructose-1, 6-bisphosphatase, which generates F6P from fructose-1, 6-bisphosphate (F1, 6P) and PC, which generates oxaloacetate (OAA) from pyruvate. The latter reaction is followed by formation of phosphoenolpyruvate (PEP) by decarboxylation of OAA; this sequence is necessary to form PEP from pyruvate, an energetically unfavorable reaction. Biosynthesis of serine/glycine (shown in olive) is also an astrocyte-specific process due to preferential expression of 3-phosphoglycerate dehydrogenase (Yamasaki et al., 2001). Both neurons and astrocytes form alanine and ribose-5-phosphate (R5P), the latter in the pentose shunt pathway (upper left corner), linked to NADPH production needed for operation of glutathione peroxidase and oxidation of monoamine transmitters. The MAS, indicated by red, transfers malate formed in the cytosol from oxaloacetate during conversion of NADH to NAD+ into mitochondria. PDH-mediated formation of acetyl CoA, which is also shown in red, initiates oxidative degradation of pyruvate in the mitochondria. Red and blue text for ATP indicates energy production and utilization, respectively. (B) Major reactions and net ATP yields or net ATP consumption of major pathways derived from the glycolytic pathway are indicated in color-coded boxes that correspond to the color-coded pathways in panel A. For simplicity, the scheme indicates the energy yields (ATP) and NAD(P)H production or utilization based on metabolism of 1 glucose to form one ribulose-5-P, two lactate/pyruvate, or 2 serine; a similar representation illustrates the energy and cofactors required for gluconeogenic conversion of two moles of lactate into one free (G6P) or glycogen-bound glucosyl unit.

This is quite interesting because should the connection between the cysLT1 receptor and astrocyte be established and explained, it shows that there is a very direct link between the immune system and metabolism. That should be intuitive because when we get seriously sick, then we are laying in bed and the body should try to conserve energy so that we don't just waste away.

So what happens if we cause changes in the cysLT1 receptor to cause the astrocytes to believe that we are sick, the normal connection between the brain and glyconeogenesis then doesn't exist. We would have to be causing some kind of periods of extreme stress on the brain because we are out moving around and doing not home sick in bed.

Maybe we should award the Chinese researchers the nobel prize? Maybe they established the connection between the immune system and metabolism? Is there also a link between the immune system of some individuals and depression? Some how, this makes perfect sense. So we have to find out and help as many people as we can.

I think that it is time to call the lawyer-biochemists to find out if this can be proven to be true and if Merck knew or not.

Is there a potential explanation for the adverse psychiatric side effects of montelukast?

In my opinion, there are at least some very good clues based upon the work of the Chinese researchers.

A 2006 report indicated that they had localized (meaning found it was there) the CystLT1 receptor (same as the receptor that montelukast
Singulair blocks) in the neurons of the brain tissue of rats. In order to do that, they injected rat brain's with NMDA to cause a chemically induced state of excitotoxicity. Excitotoxicity is a common factor in Central Nervous System disease. They concluded that both 5-LOX and CystLT1 were upregulated by the excitotoxicity that they artificially created
with the NMDA. Therefore, there would be a potential link between neuron activity and CystLT1. Nerve cells are damaged by excitotoxicity. These researchers used NMDA to cause nerve damage which caused the CystLT1 to show up. NMDA was often used in human behavior studies to cause brain damage. They would then try to observe whether behavior was compromised to conclude what areas of the brain determined what behavioral response.

So I was thinking about the Chinese researchers as I was reading other posts. One post interested me particularly regarding the mother who described behavior that seemed like hypoglycemics when their snack doesn't arrive on time. So a light bulb went on. Glutamate, another excitotoxin, can build up in the brain to a level that is damaging if humans become excessively hypoglycemic. If glutamate concentration around the synaptic cleft reaches too high a level then neurons die. Clinically, it really does seem that many people experience things that sound like the effects of hypoglycemia. It could be only a coincidence. But then again, maybe not.

The Chinese researchers found the CystLT1 receptor in the rat brain neuron after brain damage. They found the CystLT1 receptor in the normal human brain in the microvascular endothelial cells and in neuron and glial-appearing cells in brain trauma or tumors.

What role does the CystLT1 play in brain function? If it exists in brain tissue, we can assume that it does have a function. If it plays a role in preventing or repairing neuron damage due to excitotoxins, then there would be a very direct link between Singulair and adverse psychiatric side effects.

The bottom line is that Merck owes people who take Singulair further research regarding it's effect on the brain.

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.
