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  allergies/asthma hallucinations,sadness,sleeplessness,trouble concentrating,memory problems,vision changes my 7 year old was prescribed singulair for allergies/asthma 3 wks ago and as far as al/as symptoms,it has helped. she will no longer be taking this med because of scary side effects. first, she thought she saw me "fall through the couch" as well as many other strange things.then when she went to her violin lesson, she couldn't even remember the name of the instrument, then her eyes started burning and getting "glurry" as she said. I took her to the dr. and he did an eye exam to find that her vision has gone from 20/20, a month and a half ago, to 20/60 at this visit with no explanation. At this visit we also found that she had a very bad throat infection- she has complained of sore throat since she was put on singulair-the dr said it would go away w/time-now it's an infection that must be treated w/antibiotics.She has also said her heart pounds too fast and too hard and that she stays awake all night. I DO NOT think children should be prescribed this medication!!!!! F 7 3 weeks

 1  mild asthma depression, inconsolable crying, bad thoughts, self-hate, paranoia, anxiety, lack of eye contact, obsessive thoughts, low self-esteem, and fear PLEASE REPORT YOUR SIDE EFFECTS TO THE FDA - THAT DRUG SHOULD NOT BE GIVEN TO CHILDREN!! Here's my statement to FDA Medwatch on the fda.gov website: My 7 year old daughter was prescribed Singulair for asthma, 5mg once daily. After two weeks on the drug she began experiencing sudden and severe side effects - including depression, inconsolable crying, bad thoughts, self-hate, paranoia, anxiety, lack of eye contact, obsessive thoughts, low self-esteem, and fear. We stopped the Singulair after three days of these side effects. Now it's been 4 days since stopping the drug and she's slowly recovering. Furthermore, her Pediatrician agrees that Singulair is to blame for her sudden state. This shouldn't happen to a child; this drug shouldn't be prescribed to children at all. This has been a horrible experience for my daughter and my family. F 7 2 weeks

 1  Asthma My 7 year old daughter was prescribed Singulair for asthma, 5mg once daily. After one week on the drug she began waking up in the middle of the night, and after 2 weeks she began experiencing sudden and severe side effects - including depression, inconsolable crying, bad thoughts, paranoia, anxiety, obsessive thoughts (obsessed with food’s expiration dates), low self-esteem, and fear. When asked why she cries and says the things she says, she cannot explain it. I spoke to the pediatrician about this symptoms and he had never heard of them and dismissed my concerns, he even said it would be the first time this happened to someone in Latin America; he also questioned my “internet sources” when I told him I had done research on the internet and explained what I found out about the drug. We stopped the Singulair after a month of taking it. Now it's been 7 days since stopping the drug and she's slowly recovering. Furthermore, her new Pediatrician agrees that Singulair This shouldn't happen to a child; this drug shouldn't be prescribed to children at all. This has been a horrible experience for my daughter and my family. F 7 30 days

 1  Allergies & Asthma Mood changes, defiance, anger, hopelessness, crying at drop of a hat, throwing things, stomach ache My 7 yr old son has been on Singulair for 2 mos and also daily Zyrtec. He was taken off of Qvair for similar side effects. He has been unbearable for the past month. Acting out, hitting, crying, throwing things, all completely unlike him. I have been accused by my family that I have caused his change in personality because of all the yelling, time-outs, taking away video games. When he told me that he has lost all hope over improving his 1 C+, I thought there is something more going on with him. His pediatrician told me to stop all Singulair and continue on Albuteral and Zyrtec since his mood swings appear to be a side effect of the Singulair. M 7 2 months

 1  asthma My son has been on Singulair for years. However, recently, they changed his dose from 4mg to 5 mg and we noticed an obvious behavioral change. He has thoughts that prompt him to be brutally honest...telling me I am fat and ugly. He has also had homicidal thoughts toward my husband and I which are followed by self-condemning thoughts. He is a very loving child and this is completely out of character for him.Looking back, we feel horrible in that he has experienced night terrors, extreme thirst, frequent urination, blurred vision, and skin dryness. We just put all of this together when the behavioral symptoms started. My husband, thankfully, remembered the news story. We have stopped taking the medication and are 2 weeks out, but still experiencing many strange thought processes. We have even contacted a child psychologist who has encouraged us to try and "normalize" the situation as much as possible. We may have to seek further help if we don't see improvement soon.

 1  allergies loss of concentration, anxious,nightmares, wired. My 7year old daughter started taking this for a sinus infection/allergies. We had the most trying week of her young life; not listening,distracted, stole something,anxious, jealous. Just not herself, my sister suggested this site. I finally put it together and we stopped the meds immediately yesterday. Last night she had a terrible nightmare, screaming and crying. She said that she didn't know why she couldn't stop replaying these awful thoughts. I am so angry, aren't doctors supposed to be educated about the meds they're prescribing before they freely prescribe? F 7 3 weeks

 1  asthma extreme irritability,violent temper tantrums,tics,extreme sensitivity,terrible nightmares,anger My son was taking this drug for years and sadly I never had any idea that this could be the root of our problems. We even had him seeing a therapist to try and help with the behavior and anger. He has been off for 5 days and already I have seen a drastic change in his personality and behavior. I feel as though he was a sweet boy trapped in an angry body for years just trying to get out. Had NO idea Singulair produced these side effects. Not a drug that should be prescibed to children. The changes in the last week are truly very remarkable. M 7 4 days

 1  Allergies irrational behavior, ADHD like sypmtoms, anger, aggressiveness, night time fears, anxiety Our daughters symptoms GREATLY increased in severity after taking her off for a week and putting her back on Singulair. We were to the point of taking our previously "normal" child to a psychologist for testing. Our older daughter happened to catch the warning label which prompted us to take our 7yro off the drug. Her behavior has dramatically improved. The irrational behavior, anger, aggression, night time fears are now gone. She has had a very rough year in 2nd grade after having 2 excellent years in KG and 1st. We are absolutely thrilled to have made this connection. Thank you to all who have shared their stories. You made a huge difference for us as this was the first information I found and the stories were so remarkably similar it made a huge impact. Thank you!! F 7 13 months

 1  Asthma I tried giving Singulair to my 7 year old daughter twice and both times she woke up in the night with severe hallucinations. She was screaming at the top of her lungs, as though she were tied to a railway track and a train was coming. She said that the bed was flipping around and that the blanket was flying all around the room. She was holding her ears and pointing at things in the room (that weren't there) and screaming "Mommy make it stop!!!!". Her heart was pounding out of her chest....it was just terrifying. From this experience and from what I've read, it seems very mind altering. It has only been around since 1998, so the long term effects are unknown. Very scary. I will never give it to my child again. Her brain is much too precious. F 7 3 days

 1  Asthma & Seasonal allergies I was truly at my wits end with my 7 year old daughter. Her behavior at home was horrible. She'd come in the house from school miserable and fighting with everyone. I felt myselt begining to get nervous as the bus was coming up our hill not knowing what to expect from her. Since we started her on this medication when she was 3 or 4 I was beginning to think there was something "wrong" with her personality. We switched allergy doctors solely b/c our previous DR relocated. The new MD took her off singulair and increased her pulmicort does. I immediately noticed a difference in her disposition, attitude and behavior. We go back in 1 mos for another lung function test. Hopefully it's good but if not I will be looking for other options to relieve the symptoms. We won't be using singulair again. F 7 4 years

 1  asthma anger,nightmares,uncontollable crying, itching, pains in parts of his body, eye rolling, depressed and anxiety. My 7 year old son was put on this for allergies to help his asthma and it did that. But we started noticing behavior changes and he became a totally different child. It finally clicked when he woke up and his eyes were rolling constantly all day. I went on Singulairs website and noticed he had every side effect they had listed. We quit giving him the Singulair immediately. It's been 7 days today and he is slowly improving. His eye rolling is only once in a while or when he gets tired. Today was also the first time he didn't have a nightmare. I feel awful for not checking Singulair out before putting him on it. Thank you to everyone who has put something on here. It has been so helpful to read about all your experiences. M 7 6 weeks

 1  Reactive Airway Disease Huge facial tics, anxiety, mood swings, uncontrollable crying My 7 year old daughter has taken Singulair regularly for 6 months, but her behavior over the past 2 days has been so bizarre I was compelled to do a Google search and came across this website. Last night was a complete meltdown over every single thing that could have possibly been a minor annoyance, such as not being able to squeeze enough toothpaste out of the tube, which culminated in a 30-minute screaming and crying bonanza. She said to me last night that she is "just not happy" and that she doesn't know why. I was reading stories to her tonight, and she must have popped her jaw open at least 40 times over the course of two books (mouth open wide like a yawn in fast-forward). I was keeping an eye on her, and a few times I asked her why she kept doing that and she said she didn't know, and she thought maybe her mouth was "itchy" - I said "baby, that's just not normal behavior" and she said "I KNOW!!! But I can't stop, mommy!" The moodiness and crying have become progressively worse over the past few months, but the facial tic for the past month is the final straw for me and confirms my suspicions about the other behavior - I stopped giving Singulair to her today. UPDATE 12/06/2010: The facial tic that my daughter had for about one month disappeared three days after discontinuation of Singulair, and her anxiety and other mood disorders slowly faded away shortly thereafter. Her chronic cough has reappeared, but I am managing those fairly successfully with Vitamin D and Omega-3 capsules F 7 6 months

 1  ASTHMA My 7 year old son has all the same symptoms I see described here. Excessive throat clearing, bad dreams, trouble sleeping, nasty outbursts, crying, mood swings, defiance, upset stomach/diarrhea, etc. I can't believe I didn't figure this out before. I wondered why he had changed so much, I figured it was some kind of acting out because we moved last year to a new town...after a while, I figured he would adjust, but he didn't. He had never acted this way before. I'm convinced it's this poison the doctor has him on for his asthma. Thats enough of that. I'm stopping the Singulair immediately and won't use it again! It turned my son into a monster. Hopefully he will get better now being off the medicine. F 7 2 years

 1  Allergies Son lost ability to concentrate. Screamed out nightly with night terrors. Normally an excellent student, but teacher called conference to discuss his lack of concentration. Doctor told me it was absolutely not the singulair, but when I took him off the medicine he was back to my normal child. Took son to allergist and he concurred that he had heard about these side effects with singulair. M 7 1 months

 1  Asthma/Allergy night terrors, anxious, anxiety, my child seemed to live in fear Singulair became one of the major medications used to try to get her asthma under control. She had horriable dreams that would send her fleeing from the bed at night. Even when awake, the dreams seemed to continue. She lived in fear. Never wanted to be alone. She was sleeping with me, and even then she remained afraid. When someone suggested it might be singular I notified her doctor right away and she was taken off the drug. The removal of singulair makes me feel as if I have my daughter back. She's no longer afraid. She's sleeping in her room and will even hang out downstairs alone! This is big people! I almost feel like we as parents are forced to choose between our children's sanity and their ability to breathe. F 7 1 years
