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 Complete personality change in a little over two week period. DO NOT GIVE THIS DRUG TO CHILDREN. This drug came highly recommended by our allergist. He insisted we take the drug to help with modest asthma. In the period of two weeks, our good natured well behaved child turned into a nightmare: fighting, punching, overly emotional, reclusive, mood swings, anger, etc. We took him off and the problems went away.

 1  allergies anger issues, self pitty/ depression My 5yr old son was taking this for one month. One week into taking singulair he started saying Mom you hate me dont you and also having problems in school like getting up right in the middle of the teacher teaching class and walking around. He has recently started hitting other kids in his class. This is all VERY unlike him. He has always been the sweet kid and very lovey and always everyones friend and taking up for the less fortunate. I have just taken him off the med and am anxiously waiting for him to get back to his sweet self. DONT GIVE THIS TO YOUR CHILDREN!! M 5 1 months

 1  Asthma My son became argumentative and more agressive. We thought it was just a phase that he was going through but when we stopped the medication it seemed that our loving son returned within a couple of days. We found this is a common side effect with children. See side effects. M 5 2 months

 1  severe allergies outdoor/indoor anxiety, behavioral changes, withdrawn, night terrors, hallucinations,fear of bugs/spiders,afraid to be alone, ocd-like issues,& on and on My 5 year old daughter has been on Singulair for 3 years. Over the last several months,at a rapid pace, we've watched our carefree, loving, independent child turn into an anxiety ridden & worried little girl. Her nights have been full of terrors & hallucinations and her days have been spent glued to her father and myself. I sat at the computer & cried after reading most of these responses. I am so grateful to all of you who have posted your dealings with this medication.I am not alone. Our daughter has been off this medicine for 1 1/2 weeks & we are slowly seeing things improve. I hope it will continue & my thoughts are with the rest of your families who are going through this! M 5 3 days

 1  chronic congestion; cough After my daughter had taken the drug for about 2 months, she began experienced frequent daytime urination and subsequently bedwetting. Neither the allergist or pediatrician attributed this to the singulair, and we were about to be referred to a specialist for investigation of spastic bladder. I found other instances of bedwetting on this website, and stopped the singulair. About a week later, the bedwetting subsided and has not returned. Other side affects appeared to be tendancy to tantrums, increased appetite and weight gain. But we would not have attributed these to the singulair if the bedwetting had not prompted us to investigate further. F 5 2 months

 1  Asthma/allergies We have just hit the two month mark with montelukast (gen for singulair) and my independent, spirited, loving daughter has changed drastically. I don't recognize her anymore. She screams at me all day, she will not listen at all, she has been throwing violent tantrums - one of which resulted in her falling down and hitting her head. I have bruises on my arms from her kicking and punching me. She has scratched herself all over her arms, legs and chest and has been complaining about stomach pain and itchy skin. She has always been strong willed but never violent and always loving. These symptoms just surfaced about a week and a half ago. My pediatrician told me if she was going to have a reaction to the medication, it would occur within the first few days of her taking it. I thought she would be fine on it because she didn't have any adverse reactions for the first 6 to 7 weeks. The medication has helped her asthma tremendously but I am taking her off of it because it has altered her personality severely. Singular should not be prescribed to children. I am beside myself with worry and cannot wait until it is out of her system. F 5 2 months

 1  allergies and asthma Constant crying feeling sad and depressed. Was very upsetting to see happy little girl turn to sad and depressed wreck. Would not ever recommend. Hoping it will be out of system soon stopped taking 5 days ago. Worked great on symptons but could not take due to emotional side effects. No 5 year old should ever feel extreme depression like that. F 5 3 weeks

 1   Sore teeth, headaches, tummy aches, uncontrollable anxiety and obsessive thoughts, bouts of anger, bouts of crying, depressed thoughts. My son had been taking this medication for several months and it appeared to be helping his asthma greatly. About 3 months in we noticed a change in his behaviour which started with obsessive thoughts about things that could harm him- I put it down to changes at home however things got a whole lot worse to the point where he’s saying horrible things about himself, he’s constantly worried about things harming him and he lashes out or bursts into tears at the slightest issue. I have stopped this medication 4 days ago and I’m praying all these horrible side effects start to disappear and we get our boy back. DO NOT GIVE THIS TO YOUR CHILDREN!!! M 5 4 months

 1  Asthma My 5 year old daughter was prescribed singular for Asthma. The day after she began taking t she began urinating every 5 to 10 minutes. Talks constantly about having a broken leg and wanting to have a baby. We didn't know this is what was causing these problems. She took it for 14 days and all these problems are still going on. It should be banned for children under 18 years old. My daughter needs a detox it has been 4 days since we ended the Singulair. Praying there are no long time problems. I reported to the FDA but what will they do? Ended the relationship with that allergist, very unsafe. F 5 10 days

 1  cough-variant asthma My son (almost 6) was on Singulair from the time he was 2 until a year ago when I took him off due to his EXTREME behavior. He was rude and defiant at home, but at first we chocked it up to the "terrible twos". Once he began attending daycare(2 years old), though, his behavior got WORSE. He would hit and push the other children, outright defy the staff, and would NOT follow directions/rules, no matter WHAT the consequences were(time out, mom called, etc). Last year he started attending Pre-K and the behavior continued, but the staff was NOT going to take it(they didn't have to, private school). he would NOT sit still, would not finish work, and the violent behavior continued. Since it really wasn't helping his asthma, since it isn't allergy-related, we chose to take him off it and see what happened. Well, it took a couple of weeks, but he's now like a DIFFERENT child! My son now(1 year later), is exceeding most, if not all expectations at school(kindergarten), well behaved at home, and actually will sit and read books with an adult and not be racing around the room. Even his pre-K teacher, who we went back to visit, could NOT believe he's the same child! I am SO glad we took him off it, we will NEVER go back. I was interviewed by a Fox tv station in DC for this topic and can't wait to see what(if anything) comes from it. M 5.5 2 years

 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

 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

 4  asthma/allergies My daughter was diagnosed with Asthma last year after years of carrying and inhaler and running to the ER. We actually felt relief at being able to prevent her attacks. The doctor has her own predisone and singulair. We haven't noticed any real side affects and it dose seem to help keep her allergies in check which can trigger major attacks for her. After reading here though I am wondering if it s what causes her to lack of focus. am upset about learning it has aspertame in it as my husband and other children are allergic to it and we avoid it and other false sweeteners so we do not have attack from it. Our insurance recently wanted to not pay for this medicine, which we fought to get back, now I wonder if these were not the reason. I will be talking to my doctor,who is wonderful, about this medicines. F 6 1 years
