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  asthma mood swings, dpression, anxiety, fears, fatigue, listlessness at times my now 5 year old son was prescribed this drug over 2 years ago. we recently have had issue with some very disturbing thoughts he has verbalized ot us--on the order of everyone dying and him being happy with that...anyway-because i was so concerned about it, i went to this site and found, to my surprise, that so many others have found all of these same side effects with the drug in children. to the folks who state that it SHOULDN"T be given to children--do your homework before you ridicule others--it IS indicated for children according to the FDA and the AMA--how we know NOT to give it to our kids? what i can't imagine, is why the FDA hasn't pulled this drug. i see this causing SEVERE problems in our youth and i have taken my son off the drug as of this evening. please do the same for your child if they are on it.

 5  cough variant asthma None. Both myself and my 3 year old son take Singulair. The first test for my son was two weeks ago when he came down with a cold. Ordinarily this would send us running for the nebulizer, but not this time. He was fine after a couple of days with no lingering cough or wheezing. Other than an increase in talking in his sleep, I've noticed no side-effects in my son. M 3 3 months

 1  Allergies Thirsty, weight gain and occassional vomitting I feel horrible. I thought I did my homework prior to giving my 2.5 yr this crapy medicine but I didnt look far enough. Medicine cleared up the nasal drip caused by allergies but caused thirst and vomitting. People dont care about people anymore. I remember a time when doctor's were doctor's. They really cared abot their clients. F 2.5 7 days

 1  asthma After reading all of these ratings I have decided to take my 11 year old son back to the doctor today! We have been on Singulair for about 4 years and I have finally realized this medicine is making him sick! We have anxiety; stomach pain and headaches. My son never had any of these problems until being on this rx. It is awful. The awful part is it took me 3 years to realize this is what is doing it. Please be sure you talk to you doctor before giving this medication to a young child. I have the school nurse call me regularly about him having a stomach/headache and he has missed 15 days of school this year. We have had several stomach test done due to unexplained nauseau and heartburn. WELL now we know and will quickly plan to discontinue this horrible medication. M 11 4 years

 5  asthma night terror, sleep disruption, aggressive behavior (biting, hitting, pulling hair), increase in thirst, diarrhea, sleepiness during the day My 22 month-old son has taken this med for 13 days now. Within 48 hours of his first dose, the runny nose, coughing at night/with increased activity, ceased. Originally, I was very impressed. A close friend advised that Singulair has several side-effects and to watch him carefully. I did not recognize the side-effects until reading other postings on this board. He is an active (and sometimes aggressive) little boy. How do I know aggressive behavior is related to drug and not just part of his age? He has hit, bitten, and pulled hair before, but never has he had night terrors. Regardless, I am taking him off the drug and will immediately begin researching alternative medicine approaches...dietary changes, etc. I am so sorry for these other children who have suffered such severe side-effects for such a long time. Thank you to those parents for notifying the rest of us. M 1.9 13 days

 1  chronic sinusitis My son began taking singular the week he started Kindergarden. After about three weeks on the medication, he began having night terrors, itchy skin, aggressive and impulsive behavior in school, and became easily fustrated/aggitated with simple tasks. We began to wonder if he had ADHD or some other type of behavioral disorder. I then google singular and found this web site. THANK GOD FOR THIS WEB SITE!!!!!!!! We immediately took my son off of singular and within 4 days we saw positive changes in his behaviors. These side effects were completely gone in about 3 weeks. He is doing great in school and has not even had one sinus infection. PARENTS, DO NOT GIVE YOUR CHILDREN THIS DRUG!!!! M 5 3 months

 1  moderate-persistent asthma Over time, the following occurred: almost immediately began bedwetting (after being a dry sleeper); physical aggression; emotionally overreactive; irritability; gradual weight gain; always hungry; bad dreams; difficulty waking in A.M.; most recently thought he was seeing a "robber" in our house during the night (on several nights - and we don't watch scary shows) - this after a dose increase. Our son started taking it at age 5 w/onset of moderate-persistent asthma not controlled with Advair or Albuterol. He was dry at nights from age 3-1/2 to 5; w/in 48 hours of starting Singulair, he started bedwetting at night (which we attributed to Advair). We finally moved 2-1/2 years ago to remove him from the environmental triggers, got him off Advair/Albuterol, keeping the Singulair going for asthma control. Still dealt with bedwetting all this time, but thought that had a genetic component. BUT, after a dose increase last month b/c of a flare-up, his mood & behavior worsened markedly. Mood was darker, very impatient, emotionally labile-never knew how he'd react to anything. Started wetting the bed 2x/night. We "Googled" Singulair & stopped it on 1/7/08--in 9 nights he's had 4 dry nights (the last 3 nights in a row). He stopped "seeing" a robber at night; is easier to awaken; he says he feels more awake at school and it was easier to get out of bed. He sa M 10 5 years

 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  Allergies Moody, depressed, breaking into tears. Argumentative constantly and tired all the time. My 6 yr old son was prescribed singular about 2 months ago for allergies. He has become progressively more difficult to deal with. I thought he was 'coming down' from Christmas or tired due to a growth spurt but I will be taking him off this drug today! I am so glad I found this site or my poor baby could have ended up being in this state forever. He is normally such a cooperative, sweet little guy. M 6 60 days

 5  Cough My 6 year old son has a chronic cough at nighttime and during athletics. My pediatrician put him on the mediaction for this. After taking the medication for the week trial, he awoke every night crying with night terrors. I spoke to the pediatircian about this symptom and she had never heard of this and dismissed my concerns; acting as if night terrors were not that big of a deal, that my son wouldn't remember it anyway in the morning. However after reading the Singular pamplet, the side effects are listed on the pamplet stating 'night terrors'. My son has also complained about headaches more often now, and is more sleepy during the daytime. However his night terrors have stopped after 1 month of taking the medication and his cough is gone. After weighing the medication side effects and his cough, I have decided to discontinue the medication. I can't see having my child take a medication that has altered his mental and physical state to cure a non life threatening cough. I wish that my pediatrician would not have been so quick to pull out the prescripion tablet without knowing all the facts about the medication she approved for my son. M 6 45 days

 1  Asthma, Allergies Sleeplessness, insecurity, weakness, EXTREME aggression, irritability. My son was put on Singulair as a 'preventative' measure for his asthma during the winter months. In the last 3 days, he has bitten 2 friends and broken the skin, hit 2 friends for no reason, and violently scratched another friend. This is not our son. He breaks down immediately after doing these very aggressive acts and in unconsolable and doesn't know why he did it. We have been trying to understand the massive mood swing in him and aggressive behavior. Now that I have found this site and others, I am realizing that all of this started 2 months ago when he was put on the singulair - and that when he was off it before over the summer that he had no problems and was the sweet, loving, confident child he used to be. I have had 3 refills for the time he has been on this drug and NEVER received any patient information on the drug with it. I had no idea the side effects were this bad, or even that these were side effects until I researched it myself. I am taking him off and hoping h M 3.5 2 months

 3  Chronic allergic rhinitis I have been getting so frustrated with my 8 yr old son's highly emotional behaivor. Over the last month he worries about everything and cries easily. He has always been a little sensitive, but this is on a whole new level. To the point where I was getting very worried about him. He has bad dreams every night and has been wetting the bed nearly every night. I told my mom about these symptoms and she suggested it was the Singulair. I wasn't convinced but decided to look it up online anyway. I am so glad I found this site. Some of the side effects the mothers here listed sound exactly like my son. I will never give him this medicine again. THANK YOU The Singulair did seem to help his symptoms. But, as so many others have mentioned, the side effects are not worth the minimal improvement.

 4  asthma, severe cough, runny nose My 6 yr.old daughter has been on this med.(child dose) for less than 30 days. Singulair has been terrific for her asthma and cough. She no longer coughs at night or wakes in the morning coughing up mucus to the point of vomiting. However, after reading this web site I might have found the answers to some new troubles. A couple of weeks ago she started having to use the bathroom constantly. A few nights ago she started waking every hour having to use the bathroom. This is not her. She has never had an accident nor woke at night to go to the bathroom. She has gained 3 pounds in 4 weeks without eating much at all. She is now having accidents at home and school and is up all night going to the bathroom. I took her to the doctor and she said probably a urinary infection-no worries. Nothing about side effects! Is anybody else seeing any increased urination with their child? The medicine works great for her asthma and cough but the side effects are to great to keep her on it. I can't have her up all night going 'potty' and having acidents at school-she was so embarrased. I am going to take her off it tonight and hopefully see a difference within a night or two. The weight gain and bathroom issue are to much for her (and me) to deal with for the sake of no more coughing and runny nose. By the way, the label on my daughters bottle states that it is for children ages 2-14. I rated the medicine a 4 because for the actual asthma and cough it works great but it has to many side effects for children. This medicine needs to be re-evaluated for kids. If anybody else has seen the same side effects in their child please let me know, thanks! F 6 30 days

 3  asthma My son has been on this medication for 2 months after being diagnosed with asthma. All of the sudden he has been waking up in the middle of the night screaming and crying terrified. He doesn't know where he is at or who I am. I ask him what is wrong and he talks about seeing scary stuff and is even scared of me. I started to suspect taking singulair might be causing it. The few days he has stopped taking it, the night terrors go away and he sleeps great again. He has also been sleepier in the mornings and not paying attention at school. I was amazed at all the other comments on here about kids having bizarre dreams and night terrors. I took my son completely off of it since reading all of the other parents stories on this site. Thank you!!! I think that singulair is a good medicine for controlling asthma. I myself have had asthma since I was a kid and have been able to control it before there was singulair. The night terrors are not an acceptable side effect for me as mom to watch my child have. I will have to discuss another alternative with our doctor. M 5 2 months

 1  6 year old for asthma/allergies Night terrors. Wakes up 40 minutes after going to sleep and screams. Inconsolable for 10-20 minutes. Irritable, cannot concentrate. Everything seems to be more difficult for him. Major change of personality. Singulair should not be prescribed for children under 10. It seems that its side effects have a greater propensity to effect children than adults. I have read every posting here and I have highlighted every one of the entries for children under 10. Night terrors, insomnia, irratic behavior of every type, change of personality and lack of bowel control are mentioned in every entry. How can doctors prescribe this to children? Anyone reading this, please tell your doctor about this. FDA and Merck will not do anything. The most immediate point of control is the doctor. If they fail to warn and there is damage to your child, your legal remedy at first is the doctor. Because of federal law preemption, Merck has some protection....at first. Best thing to do is contact your doctor immediately. I am thinking of a suit against Merck. Sometimes being a lawyer is a very very good thing. M 6 4 weeks

 2  asthma 3.5 yr old boy, consistent sleep interruption and disruption, bad dreams, "new" fears during waking hours, complaints of stomach aches and leg pain, increased aggression and agitation, increase in rate of melt downs; This medication helped our son's physical health - asthma - but deteriorated his emotional health. His altered personality (see side effects experienced) has brought sadness to both him and our entire family. A very upsetting situation. M 3 5 days

 1  Sleep Apnea Our son was on Singulair for 3 weeks and we noticed a drastic change in his personality during the 3rd week. He became extremely moody, crying whenever he did not get what he wanted in that particular moment, and violent. He also had nightmares at night. We stopped the medication and his behavior returned to normal. M 3.5 3 weeks

 2  Allergies/possible Asthma Severe Rash outbreak, and excessive weight gain, retention of water, and lack of motivation, with slight aggression, skin tone pale I am distrubed that children a being prescriped this medication to help them adapt to envirnmental changes, or "possible" asthma. The side effects to this medication are not worth the gain. My son is starting to come back to his normal self, he gained over 25 pounds, but I am still looking at alternatives to help him get throught his outdoor allergies. M 6 15 months
