SINGULAIR  (MONTELUKAST SODIUM):  Montelukast is used regularly to prevent the wheezing and shortness of breath caused by asthma and decrease the number of asthma attacks. Montelukast is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your rescue inhaler. This medication is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). This medication does not work right away and should not be used to treat sudden asthma attacks or other breathing problems. This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.   FDA Approval Date: 1998-02-20 (Sources: U.S. Centers for Medicare Services, FDA)

 1  seasonal allergies High fever,watery stools, agressive behavior, nightmares, joint pain, anxiety, moodiness The first week after we started my son, (3.5 years) on it, He had an extremely high fever (104.7) for a week. We thought he may have been coming down with a cold/flu. He also had complaints of not being able to walk because his legs hurt. He stopped wanting to go to school, and started to hit his sister, then he would cry about it because he didn't know why he had hit her. He wanted nothing to do with me(his mom) He refused to even hug me. When he would hug me, he would growl and be so rough with me. But he was fine with his dad most the time. We never put these things together, we just thought it was his terrible 3's .I was feeling myself begining to lose patience with him. He was acting out and never listening. Before the singulair he would sit and play for hours , or "read" books all by himself for quite a long time, but once he started taking singulair, it was black and white. I ran out of his singulair for almost a week, then started him on it again. The first nite, h F 3.5 38 days

 1  allergy, sinus, astma BEHAVIORAL, TANTRUMS, OCD, ODD, MASTURBATION ( YES AT 3 YEARS OLD), DEPRESSION, PROBLEMS SLEEPING, ETC ETC AND ETC. my daughter was sick the whole winter last year, she was about 2 and 1/2 and had started daycare every morning. After catching about over 10 different viruses and always having bronchitis (forgive me my English) then end up taking antibiotics and more and even ending up with pneumonia...she has allergy + sinus + asthma issues... so our pediatrician recommended putting her on singulair, I resisted a bit, do not like drugs at all, but after all they are the doctors, right? It seem to have helped her because she stopped being sick. she took for 3 months and summer came, I stopped... winter is here again and she is sick again, now also her baby brother 8 months old, both sick and her doctor told me to put them both on it, so...I buy the singulair only for her and start giving to her...4 days later I notice my sweet angel going out of control, unbelievable change...tantrums, completely out...plus other things...NOW I GO BACK IN TIME LAST YEAR WITHOUT MAKING ANY CONNECTION I COULDN'T DEAL WITH MY DAUGHTER ANYMORE TOOK HER TO A BEHAVIOR PEDIATRICIAN. HE WANTED TO PUT HER ON ANTIDEPRESSANTS, DIAGNOSED HER WITH ADHD, OCD, ODD AND MORE. AND AGREED BECAUSE SHE WAS OUT OF CONTROL. TANTRUMS, CRYING IN THE MIDDLE OF THE NIGHT, AND I CANT REMEMBER ALL RIGHT NOW...BUT MY CONCLUSION IS THAT SWEET SMART LITTLE GIRL CHANGED AROUND THE TIME SHE TOOK THE SINGULAIR AND AFTERWORDS SHE GOT BETTER BUT I NEVER REALIZED UNTIL NOW THAT I GAVE IT AGAIN AND INSTANTLY SHE CHANGED...I JUST PUT MY DAUGHTER T F 3.5 3 months

 1  Allergies Within 24 hours, my even tempered 3.5 year old turned into crabby, crying, emotionally fragile child. He would melt down in tears and when asked what was wrong would say "I DON'T KNOW." He is usually very good at expressing himself, but since being on this, he is easily upset and confused. When he wakes in the morning, I'm telling him he doesn't have to take this anymore. I had a bad feeling going into this...no reason why as I had never really heard anything about Singulair (positive or negative)...I just had a bad feeling. I feel so terrible that my sweet boy has had such a difficult few days (major tantrums/meltdowns). He's 3.5 and I'm proud to say that I am always complimented on how lovely he behaves...not the last four days...poor sweet boy. I can only imagine it's the medicine. He has only been able to express that he feels bad all over, but cannot pinpoint an exact location. He said he felt fragile and very sad for no reason at all...scary stuff. F 3.5 4 days

 1  Chronic cough Afraid to sleep alone possible night terrors. Obsessed with not letting anyone around her close their eyes. She did not want anyone going to sleep or take naps. She couldn’t express why but it was causing her so much anxiety. She always had a little stutter that she most likely will grow out of but seemed to be magnified this week. With the stutter she started blinking her left eye which is new. Last night was her last dose and I’m hoping she will get back to normal. F 3.5 7 days

 5  Asthma, bad cough, chest infections NO SIDE EFFECTS WHAT SO EVER. My 4yr old son suffered year after year with asthma, a terrible cough and chest infections. Each year would be worse than the other. He has been on 4mg once a day for the last 2 months and it has been the best 2 months of his life health wise. I have keept a very keen eye out for side effects and can honestly say, there are NONE. I will take him off Singulair in the summer months when there are no symptoms. But will put him back on when symptoms start up again. This drug has been a blessing for us I just wish it could be this way for eveyone else. M 4 2 months

 4  Child asthma none that were noticeable, wondering if there are long term side effects?? my 3 year old developed severe asthma symptoms and was repeatedly being admitted or rushed to hospital with every cough and cold, which was being made much worse by the fact he has respiratory problems. The preventer ( steroid) inhalers were not making a difference and the reliever inhaler was giving him an increased heart rate ( very common side affect of reliever inhaler) and made him hyper and feelings of extreme hunger. Singulair was prescribed and within two weeks has changed my sons life, from virtually being unable to walk up stairs to being able to run around and he almost never gets a cold now!! The mmr vaccine has given him more terrible side effects than singulair!! M 4 7 months

 3  Allergies/Asthma Diarrhea, abdominal cramps, irritability, very dramatic behavior (crying and screaming over anything and everything), lack of focus-unable to sit still, aggressive behavior, anxiety, hyperactivity, severe nightmares My son is 4 1/2 years old and has been on singulair for 3 years; this drug definitely helps prevent his allergy related asthma attacks, he has needed his inhaler maybe 6 times since he started on this drug. HOWEVER, we accidentally forgot to refill his prescription over Christmas vacation (Dec 2005) and within two days we noticed a dramatic change in his behavior; he was calm (very little drama), focused, happy, cooperative, just a happy 4 year old boy. We contacted our Family Doctor and he advised that the negative behavior, (that we always thought was his normal behavior), could possibly be a result of the Singulair and we decided to keep him off the drug to test this theory. His daycare giver and preschool teachers all noticed a dramatic positive change in his behavior. After a month off the drug we had to put him back on it as his asthma flared up again. The negative behavior came back full force and is still with us to date...the positives have outweighed the negatives. We recentl M 4 3 years

 3  allergies My daughter has been on this for several years. While it has helped her allergies she complains of leg aches, stomach aches, is very emotional, does not sleep at night and has nightmares. I thought it was just the terrible two's going into the four's but now am going to take her off this medicine and see what happens. F 4 2 years

 3  airway reactive disease My child has been a terror since she has been on this med.(Aggressiveness,hitting, kicking,yelling,screaming). She never had this type of behavior before starting this med. It certainly helped the coughing and vomiting, but we will be discontinuing it now that I am realizing the behavior changes are not the terrible 4's. If your child's personality has changed do not hesitate to consider that Singulair may be the culprit. F 4 5 months

 3  childhood reactive airway disease irritability, aggression, waking up at night yelling, irrational behavior significantly improved daughter's breathing but turned her into 'dr. jekyll and mr. hyde'. stopped the med and her personality improved but her breathing worsened. started again 2 days ago, but stopping today...can't stand the mood swings and sensitivity. i hope we find an alternative to singulair because i really don't want her to be on it.

 3  Severe allergies inducing croup depression, agression, compulsive behaviour, mood swings, nightmares, bedwetting, teeth grinding I'm writing this on behalf of my 4 year old as I sit here crying. I didn't know that an allergy medication that has done so much to help her breathing could do this to a child! Over the last few weeks her behaviour started to change toward repetative behaviours to the point where she wouldn't play with toys, had to be colouring and cutting out everything. The bedwetting came back, the moods and aggression I figured was a phase, but a week ago the depression settled in on her and she started to cry for no reason and couldn't tell me anything that was wrong, one minute she's outside bouncing a ball, the next she drops it and her head and starts to cry. This has been repeating since. Nothing else has changed - she doesn't have a babysitter or daycare, she's not been left alone with anyone. I'm a stay at home mom. She is an only child, so there's no sibling rivalry. I've been trying to figure out where my child has gone and where the monster came from. Now I know the monster is the singul F 4 2 months

 3  improve inflamation, cold defenses My son was always bright and very active; on Singular he gradually became anxious, easily excitable, moody, contrary and down on himself. I had no idea it was the medicine. I even changed his school! Dr. and teachers thought he might eventually need to be tested for ADD. I brought up the possibile connection to singulair to his Dr., who said she didn't think Singulair was the problem because he'd always been active. We decided to ween him off 3/27 after a teacher noted anxiety; since then his behavior has improved radically. Not only is he more agreeable and calmer at home, but at school the teachers tell me they are seeing him focus on tasks and take on challenges he wouldn't have considered even two weeks ago. Singulair brought his repeated colds under control, but at a cost. Singulair reduced his suseptibility to colds. Since birth he got many colds despite being breastfed. Nearly 2 years ago, the colds got to where he wasn't over one when the next began. Finally, 18-months ago, Dr. said Singulair would reduce inflamation and give him time to heal and fight off colds. I resisted initially, but eventually agreed because he was always sick. As his health improved, he gradually became more anxious, contrary and down on himself. I thought problems were school related. But now his behavior has dramatically improved in last month since we began weening him off singular -- preschool teachers who had noted anxiety (and didn't know about sing. change) told me wide-eyed last week that they had never seen him so well behaved and willing to work. This is not just a matter of blaming medication for behavior problems as one writer below said. M 4 1 years

 3  asthma The Dr. put my daughter on this medication at age 2 after my daughter had respiratory failure due to reactive lung disease. I thought that it was a godsend as her breathing much improved and she was able to participate in simple activities like running after being on it for a month or so. At about age 4 she started having headaches, sore throats, neck pain, leg pain, stomach aches and nightmares. I have had her in the doctors office several times over the last year for these symptoms and never got any answers or indications that the singulair might be causing these symptoms. I am furious! My sweet four year old has headaches all of the time and not one of the doctors mentioned that this could be a side effect! F 4

 2  asthma/allergies agressiveness, tantrums, crying, yelling out, anger, mood swings, not listening, unable to focus, 360 change in personality. My 4 year old son took singulair on 2 occasions for about a month each time. It did seemed to help his allergies, but at the same time his personality changed drastically. At first I thought he was going through a phase. He became a different child. very difficult to deal with. I feel so guilty about getting angry at him for his behavior while on this drug. I finally made the correlation and took him off of it. After the drug got out of his system, he was back to his usual sweet self (both times). I hate the fact that I was punishing my child for his behavior when it was my fault for giving him this poison. Be careful giving this to your child and watch out for the side effects. It may work for some, but it seems like it has a bad effect on others. It is sad with the kids because they can't communicate how they feel like and adult can. What good is a medication if it makes you unable to function. M 4 2 months
