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 Severe Depression and Agression My son was on this medication for six months before I finally made the connection between the drug and his behavior change. He became very depressed, nearly suicidal, often telling us that he wished he had never been born, wanted us to kill him, and that he didn't want to live anymore. He was also very aggressive toward his younger siblings. All of these behaviors were way out of character for him--typically a very compassionate and joyful individual. Within two weeks of being off the drug we had our normal, happy, loving boy back. NEVER EVER, EVER give this drug to a child. When I related our experience to the allergist he was not surprised, has seen it before (argh!) and said that my son can't take Singulair, Zyrtec (He had similar results with Zyrtec), or Claritin. Be very cautious of drugs, parents! M 7 6 months

 1  allergies Irritability, hallucinations, depression It also did not work for my daughter's allergy symptoms. I feel so bad for giving this to her. Every day her mood has gotten a little worse, and she just feels like every thing bad happens to her. She woke us up in the middle of the night screaming b/c she thought there was a man in her room.

 1  coughing asthma Prescribed by pediatrician for our 7 year old daughter. Daily intense headaches which were dismissed as not related to the medication by our doctor - although they started a month or so after going on the medication.. Went as far as getting a CT scan because of the duration, frequency and intensity of the headaches. Additional side effects of occasional fever, dizziness and irritability. We are stopping the use of this drug immediately. The published side effects are alarming - should've done more research before taking the doctors advice on this one. No doubt we will be more careful in the future. F 7 3 months

 1  seasonal allergies My son was on and off Singular for several years for his seasonal allergies. We finally realized that he has always been a very strong willed child, but whenever he was taking Sin gular he became very aggressive. We refused to put him on this medication again. It did help his allergies, but was not worth the side effects! When I told our pediatrician he was not aware of this side effect. He went and checked his medicine book and found that increased aggressiveness WAS a side effect. Would not give to children M 7 2 years

 1  Asthma Irritability, rage, difficulty controlling emotions My child was prescribed Singulair by our GP and ever since, she has been nothing but erratic, depressed and overwhelming. Sudden outbursts, excessive crying, screaming, biting herself ... she even said she was so angry she wanted to kill herself (this is a 7 year old child -- I never could imagine her saying anything like this). After reading up a little on the internet today, there is not way I am going to give this drug to her anymore. F 7 3 weeks

 1  Daughter's Asthma/ Allergies It took a few months to occur to me that the nightly headaches my 7 year old was experiencing might be caused by the Singulair. We've noticed that her disposition has become increasingly poor - she has episodes of emotional meltdowns, has lost interest in doing almost anything (her afterschool activities/ sports, and school in general), she wakes up at night complaining of nightmares, wakes up in the morning complaining that she is already tired. She is fidgety and has experienced daytime wetting accidents. My daughter has mild to moderate asthma caused by seasonal allergies. When Claritin wasnt controlling the breathing problems, the ped. suggested this. We were not verbally warned of any of the above side effects, and whether to discontinue use if they occurred. Only after I suggested it to the ped today did he agree she should stop taking it. Daughter was taking this for approximately 3-4 mos. F 7 4 months

 1  Very mild asthma My daughter became so easily to become very angry toward anything - herself, family members, slight criticism or even most neutral suggections. She was 5+ taking Singulair for 3-4 months in total. She has not been taking any more one year. But her problem has not been changed. She is otherwise mostly a happy healthy girl. The mood problem didn't seem to go away long after stopping the medicine. We too felt being forced by the doctor to use it on our child. F 7 4 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 & 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  Allergy induced migraines My daughter was having 2-3 severe migraines a week at the age of 6. It turnes out she had a chronic sinus infection. After 2 rounds of antibiotics, the dr prescribed singulair. I honestly did not recognize that she was experiencing side effects from Singulair until now. She has gained almost 20 lbs since December, which is strange since she hardly eats!!! That is what prompted me to look it up, but I am sooo glad that i did because now I realize so many more! She has changed from a very happy, sunny child into a withdrawn,depressed child. She is very sensitive about the slightest thing, and says that no one ever wants to play with her, even though her teacher says that she is the one that refuses to interect. She has also recently experienced stomach aches, leg and ankle pain, and headaches. She also seems to have to urinate ALL the time. Although I am sure that Singulair works great for some people, I really would not recommend it for a child. Although I do not want my child to suffer with migraines again, we will drop Singulair TONIGHT. Chiropractic care seems to be a wonderful alternative for many "Tried and True" medicines. I really am grateful for this site, and I am so angry and sad that soooo many other families have had to suffer through this while just trying to eliminate another problem. F 7 10 days

 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  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 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  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
