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  asthma and allergies Bad headaches, bad nightmares, and crys about things all the time Singulair may be helping her asthma and allergies some, but I don't think these side effects are worth it. F 6 3 years

 3  Asthma & Allergies My child has been taking Singulair. She experiences excessive bed wetting. Another issue is that her teeth are all full of decay and we are wondering if its the little pink pill that sits on her teeth all night long after we dispense at bedtime. Have other families seen tooth decay/broken molars as an issue with Singulaire? I know if we stay on this medication, we are changing the time we give her the Singulaire chewable pill, definitely before brushing our teeth. F 6 2 years

 3  asthma anger, hallucinations, illusions, paranoia My 6 year old nephew was prescribed this drug to take for 1.5 weeks. He has completed the course for about 1 week now. His behaviour is very concerning, as he is rude and very aggressive and says hateful things. He is also very afraid of sleeping alone, and complains of having nightmares every night of monsters chasing him. Tonight he was crying and holding himself on the floor, saying he felt bugs biting him. There were no bugs or any bites. He also became very afraid of moths, claiming that they were coming to bite him. I am not sure if this is due to Singulair as he has been off of it for about 1 week, but thought to mention my experience. M 6 1.5 weeks

 2  allergies hyper-active followed by extreme fatigue, pounding heartbeat, confusion, anxiety, crying spells, depression, loss of focus, my daughter started taking this medicine about 5 months ago to control allergies. Other medicines did nothing for her allergies but Singular controlled her symptoms quickly. Slowly her personality changed. At first she was very chatty and no longer shy. We attributed this to benefits of after school activities. Then she slept all of the time. Everyone tried to tell me she was just growing. She began eating only half of what she did before. Then, she would suddenly start crying and running around saying "I don't know what I am supposed to do. I can't think. My little heart is beating so fast it's pounding." Her focus on schoolwork declined and her behavior grades declined. I could not imagine my 6 yr old suffering with a mental breakdown. Then, for the first time, the warning label appeared on the prescription. I thought it was a mistake until I found this site. Now it is all clear. I discussed it with her doctor and stopped Singular immediately. It is now listed under her drug allergies. I would never give this to a child. According to her doctor this medicine actually is in the same family as antidepressants. There are multiple warnings about antidepressants in children. I can't believe they are marketing this medicine to children. It needs to be banned for use in children. I pray all effects are reversible. F 6 5 months

 2  son - asthma very aggressive behaviour, violent tantrums, screaming, night terrors, unreasonable, argumentative, drowsy It did control his asthma attacks but since we started it in October 2007, our sweet and humourous little boy turned into a monster. He screams for no reason, refuses to wake up and get ready for school in the mornings, argues all the time, gets into a rage over the smallest of things, hates leaving the house and is always upset. I kept wondering what changed in the last year - and then I remembered that that is when we put him on Singulair. I have been researching it on the internet and I found this and other similar reviews from other parents. I will take him off the drug TONIGHT. I hope I get my sweet boy back. M 6 1 years

 2  Asthma I have thought this is a wonder drug for the past 2 years, but just found this site and realized that the side effects listed have been happening to my son. Over the past two years he has not been able to concentrate and listen very well, has had episodes of mood swings, an itchy penis, dry skin. He seemed to be growing out of these things, so I thought it was a maturity issue, but the Dr. just increased his dose and it all the side effects came back in full force. I took him off of it for 5 days and noticed all the side effects went away. Use caution and test this medicine. M 6 2 years

 2  asthma Our six year old daughter started taking singulair (pediatric dose, of course) last monday and subsequently for another 3 nights. First night, "bad dream", her words, followed by a night spent coughing. Second night nightmares with more coughing. Third night nightmares and what I would only call hallucinations where she woke up and held her hands apart about two feet and clearly stated over and over again that she could not hold "the thing" while getting more and more frustrated and crying. Fell asleep finally only to wake up a few hours later with the worse coughing fit ever that lasted well over 1 hour and was repeated several times that night. Same thing on the fourth night. Enough! Talked to my pharmacist who suggested that I stop giving her Singulair and just continue with her regular asthma medicine, which is what I did. Next appointment with the asthma specialist is in September. I'll keep reading everyone's comments to see if I will start her on it ag F 6 4 days

 2  allergies, acute asthma, croup Coughing, post nasal drip, constant runny nose My son was put on singular for asthma and allergies. While on singular, all he did was cough. There were times when he would goto bed and cough for 2 1/2 hrs. before falling asleep. Sometimes this would develop into croup, which required a nebulizer! Now he is off the singular and has NOT coughed in three weeks. My 3 1/2 yr. old son was on it too for the same reasons and had horrible mood swings. He is NO longer on singular either! M 6 2 years

 2  Asthma/Allergies My six year old daughter has been on and off this medicine for the past 4 years, in this time I have noticed her calm pleasant demenor go to something I have never seen. Just recently she seems to be doing awful in school, not wanting to do her work, hitting others for no reason, and lashing out as it she hates the world. I have stopped this medication and will consult with her allergist. My hopes are that while quitting this will bring back my sweet girl, other parents can find another alternative to this medicine before having to find out the hard way the affects it can have on a child.

 2  asthma Son commenced singulair 4mg a day when he about 3 years old for asthma that was getting very severe. Great at first, asthma cleared right up so we could put the inhaler away almost completely. Slow but progressive behavioural problems in preschool and kindergarten to point we took him out of school as disrupting other students and teachers. He seemed so angry, touchy, hypersensitive and miserable. Didn't consider Singulair to be the cause until we revisited the medi info as we were at wits end. Also son has preexisting problems with ears which we misinterpreted as being partial cause of problems.. Been off Singulair for over 3 weeks now with doctor's consent with management and he has really lifted in mood and has improved dramatically at school. The doctor does not seem to rate the side affect very seriously. The longer term affect of the drug seems to have altered our son's overall perceptions of his world. He's much happier already but he still draws things that worry his teacher f Works great on the asthma symptoms but be absolutely vigilant for side effects on mood. I would say only to prescribe this to children old enough to realise and be able to communicate that they are getting depressed or moody etc. My son was still learning to speak when he started on singulair, coupled with hearing difficultes which clouded our view of what was happening to him.

 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

 2  no Irrational anger, agression, hitting, crying, kicking, nasty, screaming, waking in night and they would tell me they didn't know why know why they were feeling this way. I thought I was a bad mom till I started researching this drug. Ther is a Natural Alternative called RESPITROL. Initially like most natural remedies it takes time to work but it does work AND there are no more irrational behavioral outburst. My kids were telling me they were bad kids when on that horrible drug. Now they tell me they feel really good like they never did before. Can you imagine how many parents think they are bad parents and other kids feel they are horrible kids? Spread the word and ask your doctors to help you use this product. If they won't, find one who will. We have to stop drugging our kids. There are so many great alternatives out there. Most drugs cause negative side effects, and aren't even tested for kids! They are unnecessary as I am also finding out... for example, most kids are deficient in Vitamin D which will prevent flu and colds. Diet is also important. BEAWARE: aspartame is in singulair which itself has many negative side effects like depression, irritability, anxiety and personality changes [it in a lot of your processed foods]. Educate yourselves! M 6 2 years

 1  Asthma My daughter, now 6, has been on singulair since she was like a year old. She has always seemed sad and worried about everything and at times had the "glazed over look". Her father and I divorced when she was very young and it was not the nicest divorce. We always chalked up her "issues" with the divorce and spent lots of money on therapists who couldn't find anything wrong or abnormal. Recently, we uped her dosage due to her age and her asthma still not being under control. She startd having some even crazier behavior problems! She was more angry and at times, out of control. She was anxious all the time to the point the school called to talk about it. She seemed more sad than usual and sometimes out of it! She complained of a tummy ache all the time. She was just a different kid, worse than what we had grown "accustomed to". I heard a story on TV about Singulair and the side effects. I started doing research on it and immediately called the specialist who M 6 5 years

 1  asthma/allergies After stumbling upon possible side effects of Singulair and finding this website, I took my 6 1/2 year old son off Singulair. He had been on it for almost 3 years. It has taken almost 6 weeks to see him "evolve" into a "normal" child. He cried off and on for the first 2 to 3 weeks and I was starting to wonder if I had done the right thing. It turns out that I have. I am dismayed beyond belief that not a SINGLE MD or RN never suggested that this drug could be causing these issues ("I dont know whats wrong with my brain, there is something wrong with my brain mommy!", bouts of solitude, angry outbursts, uncontrollable behavior,constant throat clearing, etc...)in my bright and loving son. I am more dismayed with myself that I never put 2 and 2 together, he was put on it at such an early age. Never again will I give my child something without first researching the side effects. This drug is toxic to children, and from what I have seen, male children in M 6 3 years

 1  asthma & allergies sleepwalking, night terror, mood changes, no self esteem, anxiety My 6 yr old son has been taking singulair for 2 years and I am just putting together all of the problems he was experiencing with the meds. He starting showing changes in his mood, nightmares, sleep walking, saying he hates himself, anxiety that something were going to happen to his family etc. It has gotten increasingly worse within the last 2 months so I started looking into what could be causing it. After coming across this website I called his allergist and was told to stop the medication IMMEDIETELY! My son has been off the meds for 3 days now and we are starting to notice slight changes in his sleep and behavior. Lord willing my sweet little boy will be back to normal soon with no lasting effects from this drug. It makes me sick to know I was giving this drug to my child for 2 years. M 6 2 years

 1  allergies/asthma Aggression, tantrums, moodiness, tired, not listening, crying My son has dealth with postnasal drip and asthma that comes on during the middle of the night since he was born, we saw a new pediatrian 2 weeks ago and she said 'your son has allegies and needs to have his asthma under control' and prescribed singular. At first I was so happy to finally have some answers and a 'solution' but boy was I wrong! With in 2 days of taking this medicine, my son who is my mellow child and very caring and loving started throwing tantrums like i've never seen any of my children do, he was agressive, would not listen to me or his father, then after a couple more days started hitting his sibblings, punching them to a degree more than 'normal' sibbling playing around. I then looked closer at the side effects of the med and saw 'mood behavoirs' listed under 'possible side effects' ok I thought it would maybe level out after 2 weeks on the medicine. While the screaming tantrums have mellowed out, the other things have not and finding this site tonight seeing the other comments, confirms my resolve to not give him anymore Singular. I have my sons 6 year check up in 3 days with his usual pediatrician and I'm going to give my complaint to him about the side effects of this medicine. M 6 14 days

 1  Congestion from allergies uncontrolled urination & bowel movements; nightmares, inattentativeness at school; moodiness; slight aggressiveness; sleep walking My six year old son was on the medication for about three weeks before the abrupt changes in his personality. The first indicator was a phone call from his teacher very concerned with the unexplained "accidents" he was having at school. This was very unlike my son considering that he never had any type of "accidents" since he was potty trained at two years old. My son's teacher also described my son's inability to concentrate and almost an unwillingness to do his work. The potty "accidents" continued at home with almost a daily occurence. I began noticing a change in his level of moodiness and aggression. Unhappy with a conversation I was having about him with his grandfather, my son hit me with a plastic toy bat. What was alarming was the action, not necessarily the force. The straw that broke the camels back was when he was caught sleep walking. He ended up in my kitchen, removed his shorts and underpants and urinated on my dining room chair and kitchen floor. He was completely unaware of the incident when he woke up later that morning. It wasn't until I connected these changes to the onset of putting my son on this medication. I passed along my concerns to his pediatrician who merely dismissed it as a change in his diet and now having a sleep walker on our hands. Her advise was to bulk up his diet and to put gates and bells around the house to awaken us if my son continued to sleep walk. I know my son, and I know his behavior patt M 6 1 months

 1  allergies Angry, moody, tantrums, never happy, never smiling. Frustrated easily. Fighting constantly with sister and family...now even grandparents, aunt, etc. My son has been on and off Singulair for years. When he was off in the summertime, I had my son back. After reading this site, I am thrilled to see that there might be a reason for this unbearable behavior. He does very well in school and this problem does not carry over there. So, I didn't attribute it to the meds. I am taking him off today and will be patiently waiting for a change! M 6 3 years
