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)

 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

 1  Seasonal allergies Increased weight gain,Moody, aggressive,depressed,etc.... My 8 year old son has been taking Singulair for quite some time now. I never made the connection to all the problems I have been having with him, until a friend of the family sent me this link. I read in horror the stories from other parents, the symptoms that their children were having mirrored that of my son. I was having such a terrible time controlling him, I didn't know what to do. He has been doing horrible in school, and is even worse at home. Without even consulting his Dr. I threw away his prescription of Singulair and Flonase.It has been about a week now, and I am slowly seeing some changes...for the better. His allergies are starting to come back full force, but I have no idea what to put him on now.I have been researching other allergy medicine web sites only to find that the side effects for many others are the same ( Zyrtec, Claritan, Benadryl) as well as many others. I hate to see him suffer but I have no idea what to put him on now. If anyone has any suggestions please M 8

 1  asthma and allergies mood changes, extreme irritability, difficulty focusing, anxiousness, severe crying bouts, depression, low self-esteem, vivid and terrifying dreams, stomach pains, muscle pains, etc. Our sweet little girl began taking Singulair 7 to 9 months ago to help manage her asthma and allergies. Initially, it seemed to do the trick. She's gone over a year w/o a hospital admission. However, we also noticed that she began "acting out" a lot and she just didn't seem herself. She began having much difficulty in school since she could not concentrate. She began crying in school everyday out of frustration as well as at home. Where did our happy little girl go? She is on several meds for her conditions and we never stopped to think it could be Singulair that would cause these side effects. However, over the last few months she has had increased trouble with sleeping and waking nightly with vivid terrifying dreams. We've also been told that she needs to repeat kindgergarden due to her difficulties in school. The benefits DO NOT outweigh he risks. We've chosen to help our precious little girl find her happy self again. We've missed her! Please, think twice abo F 5 7 months

 1  asthma, fluid in ears, wheezing paranoia, anger, tantrums, hatred, aggression, poor appetite my 5yo son was prescribed this about 2 wks ago. He has become afraid to go anywhere in the house alone..in broad daylight. He is throwing fits at night about not wanting to go to bed, he has been screaming 'i hate you' to his father and I, throwing things, upset about everything, cannot just sit to focus on simple tasks (eating, chores,etc). My older son had had a similar reaction to lg dose of dexamethasone (steroid) for croup when about 2yo so that made me look into this new med my youngest started. We are stopping it today.

 1  Suspected Asthma (RAD) My son was prescribed the drug when he was 3.5. He experienced night terrors, constantly complained of stomach aches, could not focus, had extremely low self esteem, worried that people were laughing at him, irritable and moody, exhibited agressive behavior and perseverated about very minor issues. Things got so bad for my son, we had him evaluated by a psychologist. We stopped the Singulair and most behaviors all but disappeared within a week or two. He is now a slightly quirky (but typically happy) 5 year old. I still wonder if he has any lasting effects from this med. M 3.5 1 years

 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

My daughter had been taking singulair for 3 yrs .She suffers from severe allergies and exercise induced asthma. Singulair seemed to be fine at first but when she started acting out I never thoght about connecting the two.She began having trouble with attention and was becoming a little monster! Things went from mild to full blown rebellion over the course of a year.She began hitting,bitting,and lying over every thing. She went from having a quite demeanor to having a sarcastic,smarthmouth attitude. I thought it was pretween thing,she is 9 yrs old.She is a GT/straight A student since first grade. And all of a sudden started having trouble with simple homework and complained about not being able to concentrate.Her average went from A to D over a 6 week period. We had a parent teacher conference,where teacher expressed concerns over her behavior and concentration. Her pediatrician referred her to a nuerologist and he determined she was having mild seizures.

 1  fluid on ears, difficulty breathing My son changed completely in the course of one week of this medicine. He has been hyper, unfocused, and full of fear and anxiety (nightmares, other fears). He has had intense stomach pain as well. He has dissolved into tears in situations he would have normally handled with ease. He's off the medicine and will not go back on it again. M 8 9 days

 1  exercised induced asthma it was for my son who was 1 1/2 at the time, within minutes of taking the granulants he began projectile vomiting. He began acting in what I can only describe as a bad trip. He was running back in forth from myself to my husband screaming in terror as if he didnt know us. he would look around like he was seeing things flying through the air. I told his doctor who said to try it one more time to see if it was the "Nausia" so we did and got the same results. We immediatley took our son off of this prescription. M 1 2 days

 1  asthma My 5 year old son changed dramatically. Self hatred, unfocused, no joy, depression, stomach pains, chronic sinusitis, rage, suicidal thoughts (yes he's 5), thought everyone hated him, extreme emotional sensitivity...the list goes on and on... He's now been off it for a month, and we have our loving child back again. This is a poison to some, please be very cautious if you are someone you know is taking it. Remember children can't put into words what adults can, look for the smallest of signs. M 5 6 months

 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  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 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  allergies Severe depression, mood swings, aggression, lower muscle pain, nightmares, poor concentration If you are thinking of putting your child on Singulair...don't do it. Our daughter was on it for 3 months and the side-effects were so severe that we were considering taking her to therapist. She immediately started complaining of leg pain, and then the nightmares started. Within a month, her personality began to change and she became very violent and sometimes depressed. We didn't even recognize her anymore. She has been off Singulair for 3 months now, and she is back to being herself. She can sleep again and her pleasant nature has returned. Singulair was a nightmare for us! F 4 3 months

 1  chronic asthma I had given this med to my 4 year old son since 06/07. We started experiencing negative side effects about 3 months ago. He was weepy, clingy, irrational, and mean at home. Things he normally loved to do, he began to be afraid of and have anxiety over situations. I saw on the news FDA was investigating this drug and I immediately called his pediatric pulmonologist. I feel uncomfortable giving this drug to my child. As of today, I have discontinued use of singular. We will see if his behavior improves. I am praying that it does. M 4 10 days

 1  Cough-Variant Asthma My 4 year old son experienced Tics while taking this medication (blinking his eyes, shaking his head, opening and closing his mouth, clearing his throat, making a sqeaking noise). Once we took him off the Singulair, it took a few weeks,but we did notice an improvement with his Tics (he had never had Tics prior to his taking Singulair). He was also taking Albuterol - maybe it was a combination of the drugs, but honestly, it was the scariest thing we ever encountered with our son. In observing him for a 15 minute period, he would shake his head 25 times (and it was a violent head shaking - like that of a dog shaking off water) and open and close his mouth 6 times (like he was trying to unblock his ears). He seemed to constantly make the sqeaking noise. It has been almost 3 months since we have taken him off of Singulair, and it appears that the TICS are finally gone. I would NEVER recommend this drug to anyone - it caused such stress and trauma in my family. We talked to 4 separate doctors, and only one doctor agreed that in his opinion, the Tics were triggered by Singulair. I do believe that my son was probably genetically pre-disposed to Tics, but absolut M 4 6 weeks

 1  Allergies and Asthma Aggressive behavior, temper tantrums, nervousness, anxiety, depression, hair loss, hyper,moody,unusually tired in the mornings. My now five year old son was prescribed this medication when he turned two. Approximately 6 months after taking it, his entire demeanor changed. He turned into a very moody, angry, sad child and started losing his hair. The pediatrician, allergist, immunologist,dermatologist, and specialists all said that it could not be the medication causing his hair loss. He now has no hair at all. Recently, I have found links to Singulair and hair loss and I am ANGRY. My child has been treated for Alopecia for now 18 months and this terrible drug could be the cause. As soon as I found the connections to his behavior changes and hair loss I took him off the medication. It has been three days now, and I have already noticed a modification in his agressive behavior. Parents should be aware of the harmful affects of this medication. M 5 2.5 years

 3  Asthma excessive/rapid weight gain, thirst (especially in afternoon), some anxiety, trouble focusing on tasks I am so relieved to have found this web site. I saw an article in the news today and did some research. My daughter has gained an unexplained 10 pounds in less than a year (without gaining much in height like you would expect for that kind of weight gain in a child) & she is a very healthy eater for her age. She eats virtually no trans fats, drinks no fruit juice/soda, swims twice a week, plays basketball, softball, etc...I can't believe that Singulair could be responsible. The worst part is she worries about being heavy & I keep telling her she will grow out of it. It could also explain her anxiety and trouble focusing (which I attributed to her age). I'm going to take her off today & see what happens. Her asthma is not completely under control anyway and we are seeing the doctor in a few weeks for more options. How scary. F 9 18 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!
