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)

 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

 3  mild asthma and allergies My son, who is almost 4, has been taking this for only 1 month. He has been acting horrible ... irritable, moody, mean, trouble going to sleep, trouble waking up, crying uncontrollably for no reason and bad dreams at night. I was at my wits end this morning and didn't know how much more I could handle with him. Then my husband found this and another website that explained some of the side effects of Singulair in children. I am positive that this is what has changed my sweet boy into something unrecognizable to me. I am stopping his 4 mg tablet today! Do not give this drug to your yound child. It is not worth it. My 3 year old son only has mild allergy triggered asthma. I will find another way to control it. M 3 30 days

 3  asthma Same as others, change in behavior for the worse. Mood swings, unhappy and sad, irritable, biting, kicking, tantrums, biting finger and toe nails. Worried about all asthma meds my son is on. After starting singulair, things were increasingly worse. I noticed changes when he was first diagnosed with asthma and was given albuterol and pulmicort and prednisolon. His mood changed immediately and drastically. He became a fearful, spastic, nervous, easily set off little boy. Then he began Singulair and things were even worse, within 2 days he began nail biting and having tantrums, head butting and biting and was over excited at odd times. Once he began Nasonex, I thought I should take him to a psychologist, began exhibiting what I thought were autistic behavior, withdrawn, repetitive behavior. After reading this site, I am wondering if these meds are the culprit that changed my once happy, cheerful, very laid back little boy. Singulair was successful in eliminating his usage of albuterol, no attacks since, he is virtually asthma free with all the meds in the "athsma capital" that we live in, but I want alternatives, n M 3 1 months

 3  Allergies and asthma My 3-year old, who is normally a high energy little boy, started jumping off the walls morning til night. He couldn't sit or stand still and started getting upset very easily - he was very crabby. He became pretty difficult to handle - we were starting to wonder if he was showing signs of ADHD. He started waking up in the middle of the night, sometimes sobbing. It has seemed to help his allergies, but with these side effects, I don't think it's worth it. We found out about the connection between singulair and hyperactivity through a chance encounter with another parent two days ago. Two nights ago, we stopped giving him Singulair. We think we've already seen some positive changes but time will tell. We are a bit upset with our doctors (my son's GP and the allergy/asthma specialist). Neither one mentioned these possible side effects. But I am even more upset with myself for not doing better research before I gave my child medication. Lesson learned! M 3 2.5 months

 2  seasonal allergies/ asthma Mood swings in 3 year old son. Hyper-activity, sleeplessness and irritability. Angry and agressive behavior. At first, we thought this was typical three year old behavior. After reading the posts on this drug I am convinced that it is all a side effect of his medication. He has had his last dose and I am expecting my "good boy" back any day now. M 3 3 weeks

She put on alot of weight, which the DR. didn't tell us this would happen.She has been off the drug for a couple of years now but her eating habits are not normal for a child this age.Has anyone else experienced this problem?

 2  Croup/asthma-type cough Turned sweet, laid-back child (3 yrs) into a terror. Our son was full of anger, lashed out constantly and cried like he did when he was a baby. At night, he talked in his sleep and was grinding his teeth so loud we could hear it in our room. PARENTS BEWARE OF BEHAVIOR CHANGES! M 3 2 days

 2  allergies My three year old son was put on Singulair due to his allergies, however over the course of three months we noticed that he had become a child we did not know. He was very hyper, moody, irritable, and aggressive. These characteristics were totally opposite of his fun-loving, happy-go-lucky behavior prior to this medication. We finally took a chance (before doing research) and took him off of the medication and within 24 hours he was back to his normal self! This road was definitely a rocky road, even to the point where we were questioning our ability as parents! BE ADVISED!!!! hyper activity, aggressiveness, moodiness, irritability M 3 3 months

 2  allergic rhinitis sore throat, vomiting, decreased appetite, increased aggression My 3 year old son commenced on singulair as a trial to reduce the allergic rhinitis. Discussed with his doctor today regarding behavoural changes and possible side effects. He was not aware of behavioural changes with this medication. We agreed to stop the medication as I feel it is affecting his mood and at times uncontrollable rage. I also think is appetite has decreased. I do not believe this is 'age related'. M 3 5 weeks

 2  Severe Seasonal Allergies Anger, Aggression, Hostility, Moodiness, Spaced out, Decreased Appetite, Irregular Sleep. I also noticed his face has blanched, eyes have dark circles, and he has been chewing on his hands constantly. (something he never does) My son started taking this medication only a few days ago due to severe uncontrolled allergies. Since beginning this medicine, my son has had severe mood problems that I was attributing to a cold he caught a few days before the Singulair was prescribed. In only 5 short days I my child changed from a sweet and usually happy go lucky little boy to an aggressive and emotional mess. He stopped napping, sleeping like normal, and he has lost his appetite altogether. He yells at me, screams NO to everything I say, and he has been chewing his hands constantly for the past 3 days. The temper tantrums haven't stopped since starting Singulair. I know he has only been on the medicine for 5 days, but the fact that I noticed such a big change in his behavior to google search "singulair behavioral problems" should tell you something. Effective immediately I am taking my child off this medication. While it has been the only thing to help his allergies, it just isn't worth the side effects. M 3 5 days

 2  Asthma Mood and behavior changes, dry mouth, irritability Three doctors and a PA strongly advised us to put our 3 1/2 year old son on Singulair to help prevent the increasing problems he is having with asthma. Because I have heard so many negative things about putting children on steroids like I have had to do with our son I decided to give it a try. Within one day he began to have behavioral problems such as hyperactivity & irrational mood swings. Within four days he had a terrible asthma attack and we are still in the process of trying to get him through the breathing problems. His pediatrician has him on Singulair, a nebulizer, and two steroids (one liquid, one inhaled) I asked that at least one thing be eliminated since it seems like that's an awful lot of medication for a three year old. We took him off the inhaled steroid and I am monitoring him closely to see what could be causing his wild behavior. My suspicions have been that it is the Singulair and after finding this website I am now certain. I am thankful to find that others had the same problem - when I asked my doctor, I too got the response "there are not side effects" and "it would be worse to take him off". My son is on the autism spectrum and already has many difficulties - he certainly doesn't need this on top of everything else. Does anyone know of any other alternative solutions for children with asthma that doesn't require all these crazy medications? This website has truly been helpful and I'm hoping to find out more informati M 3 8 days

 2  Asthma My sweet, bubbly 3 year old began having panic and anxiety attacks. She would start crying if dirt got on her. She didn't want to play with her friends anymore. She had nightmares and was up every night. SHe had started a new school so I wasn't sure if it was the medication or the situation. We stopped anyway and saw an immediate improvement. She is back to her sweet self and we are managing her Astma with Pulmicort. Her allergist was not willing to even entertain the thought that the Singulair could have been a cause of her behavior change. He sighted research studies that showed no adverse reactions like this. All the research or paper in the world will not convince me that Singulair did not cause my daughter to have these bad effects!! F 3 2 months

 2  Allergy Induced Asthma Mood swings, irriatiblity, sleeplessness, night terrors, Ear infections, clingy, hitting sibling. We added this medication to his asthma routine as he would have a persistant cough that sounded like a seal for the allergy seasons. Well, I noticed an increase of mean behavior toward his sister, he was waking up persistantly throughout night. Would wake up with night terrors and not know who I am. TOOK forever to calm him down. He also turned from an easy going kid, to a defiant child and also very disturbed whiny kid. Took him today to doc for ear infection, which has increased since putting him on this medication. I am NOT giving him his dosage tonight. My son is normally a sweet boy, but has since been turned into a monster! Thanks for all the comments! You helped me determine it's not just in my mind!

 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  Allergies Mood swings, temper tantrums, aggression, irritability, nightmares, and poor appetite. My son started taking Singulair to combat repeated ear and sinus infections. At first, there was no noticeable change in his demeanor until recently. In the last several months, his mood changed and we were at a lost to explain the aggression and irritability. We were told about the recent studies and found this website and immediately took him off the medicine and noticed an immediate change in his demeanor. We had our happy, easy-going son back.

 1  Persistent Asthma The side effects of this med on my 3year old were devastating. He went nearly 48 hours without sleeping. He couldn't even maintain eye contact with us he was so hyper and aggressive. He would go into tantrums and roll around on the floor. Not at all like our child's typical behavior. He was on it less than 2 weeks as I was told these symptoms might get better after two weeks, but we simply could not put him through it and took him off. I am very concerned about the side effects of this drug. I am sorry I didn't take him off it the minute I saw the changes. I knew it was not right immediately. M 3 2 weeks
