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 thoughts of dying, scared, bad dreams, very short temper, aggressive, hyperactive, angry complete change of personality My daughter was prescibed Singulair after a hospital admission. Her Asthma is thought to be triggered by viruses. The tablets seemed to have good effect with regards to her Asthma. She has been in and out of hospital too much in her short life and i was really hopeful that we had found something to help her. A month later her baby sister was born, she became very aggressive, would get extremely angry at the smallest thing and scream and shout, she had nightmares about fires and was scared to stay at friends who had an open fire. She would hit out and not listen, she was impossible to reason with and could not sit still at all. Her pre-school teachers started to ask if she was on Steriods as they knew these made her hyper, but she wasnt. This drug has it's place, but it's not right for my child, her behaviour was blamed on having a new baby around, i felt awful when i realised. After a week of stopping it she was calmer, after three i had my lovely affectionate, good little girl back, be very careful to monitor side effects if you have to try this drug, it certainly doesnt seen to be good for alot of children.

 1  Allergies My 4 year old daughter was halicunating. She would sit up in bed and scream for me to cover her eyes. Each night she saw bubbles that would "painfully" pop by her face. Also, she wet the bed for the first time in 1.5 years. She cries over every little thing and is emotional. I am stopping this medication right now. I can't believe this is on the market! I am furious! F 4 3 months

 1  seasonal allerigies/asthma my son's behavior changed dramatically after 5 days on this drug. he became aggressive, crazy, ultra-sensitive. i took him off after finding this web site. thank you all!! he is back to normal after three days off and using nebulizer as before. this drug contains aspartame, something my pediatrician did not tell me. aspartame gives me headaches and makes me "foggy". i stopped drinking diet coke years ago because of the effects.

 1  Allergies My 4 year old son has been taking Singulair for three weeks. We immediately saw a behavior change. He became hyper and aggressive at school. He had an episode where ittook three teachers an hour and a half to calm him down. He said he doesn't know why he got so upset. He has been competely out of character for the past couple of weeks. I am so glad I started to research this medication. Last night was his last and final dose. My son is somewhat excited anyway, this took him over the top. I wish healthcare providers would let parents know the possible side effects of this medication. M 4 3 weeks

 1  asthma extreme sensitivity, irritability, aggressiveness, depression, anxiety, difficulty sleeping. I am filling this information in based on experiences with my son. Singulair was a miracle for us when he first began taking it just after his 2nd birthday and worked well for the first year. At the beginning of his 2nd year on the meds he started showing the symptoms above. We took him off the singulair and maintained his other asthma meds as previously prescribed...the symptoms disappeared completely after about 2 months. No other changes to his meds were made.

 1  upper respiratory/asthma/allergies Our high energy, 4 year old son WAS on Singulair for 1.5 years. He showed many of the classic symptoms of being on this drug. Very aggressive behavior, sensitive to small issues, moody, lack of focus/concentration, cried ALL of the time over NOTHING, fight, kick, night terrors and complain of leg cramps...I could go on and on... He often said to us, "I try to control myself, but I can't." It broke our hearts. He was asked to leave a private home daycare because of his aggressive behavior. His pediatrician sent us to 2 behaviorists - NO ONE questioned the meds he was on. It wasn't until my husband forgot to give him the meds for a couple of nights. His teacher even noticed the change and said, "he's loving & funny" and she noticed a significant change in his behavior also. I found this website and it was like reading our life. His pediatrician & pharmacist both said very few children show side effects, however, we completely disagree. We've had 3 other friends take their children off the drug & also say there's quite a difference. The FDA needs to take a closer look at prescribing this for children. After reading this site it appears it effects children differently than adults (I'm on it & don't have any symptoms like this, age 39). I know medications have different side M 4 1.5 years

 1  Allergies My son was 3,5 yrs old when he was prescribed with the medicine. He started having bad nightmares, woudl scream in the midle of the night with his eyes closed and when i went ot his room and he heard me, he would go back to sleep but this would keep on going. Also, extreme sensitiviy, lack of concentration, irritability. I would rather have him have minor symptoms of allergies and manage those rather than have him troubled with the side effects M 4 40 days

 1  asthma/allergies My 4 yr. old son began having huge meltdowns which would last for and hour or so. He is usually very easy going, but was now having rages in which he would cry, scream, bite, kick, hit, and require someone to hold him to keep him from doing these things. Then, afterwards he would say he didn't know why he got so upset. I knew something had changed because he had never had meltdowns like this before. I realized that they started about 3days after he began taking Singulair. We stopped the medication about 3 days ago and he is gradually getting back to his normal personality. I think this medication should be researched further in children because of all of the negative behavior side effects. M 4 7 days

 1  asthma/allergies? My 3 1/2 year old son was givn the medicine because he had severe coughing spells, that couldnt be explained. The doctor gave us samples while we waited to see a specailist. 4 out 7 nights on the drug he wet the bed, he became very inpatient, sensitive, thought people were laughing at him, more agrressive,biting his brother, difficulty sleeping, crying in his sleep, nightmares, antisocial etc etc. My son experienced these symptoms after one week, BEWARE!!! of this medication the risks just dont out way the benefits. My once outgoing child became afraid to go to school and depressed after one week, said he didnt want to be happy and was telling me he did things that he hadnt, bad things! I can only imagine what may have happened if he had stayed on the meds. Do not give your children this medication!How dare drug companies give out this medication when there are so many horror stories out there. Shame on them!!!!!!Ps Two days after stopping my son is getting back to his old self and hopefuly in a couple days I will have my happy fun loving child back. M 4 7 days

 1  asthma & allergies Woke up at night screaming with leg pain, terrible moodiness, cried a lot, had many tantrums, withdrew from play at pre-school. It was horrible. My 4 1/2 year old son was put on this for asthma triggered by allergies. He was miserable! He woke up every night screaming of leg pain. His pre-k teacher contacted me 3 times regarding him not being himself: crying all the time, tantruming, not playing. Dr. took him off Claritin first, b/c "Singulair is so well tolerated." Well, he didn't get better. So, I took him off Singulair a week later and he actually slept through the night the first night off! His mood improved after 2 days off, and I'm happy to say, I have my sweet little boy back. M 4 1 months

 1  Asthma with colds Irritability, pallor, emotional outbursts, trembling, poor appetite My sweet and bright little boy experienced alarming side effects immediately after starting Singulair for asthma symptoms that he experiences when he has a cold. He became pale, insecure, emotional and quite simply, not the precious child I knew him to be. I discontinued Singulair, and I am eager to find a safe alternative to control his asthma. I do not understand why my son's physician is unaware of the extreme side effects that Singulair may produce! M 4 2 times

 1  Prevent asthma My 4 year old was prescribed Singulair by his Pediatrician to prevent his asthma attacks. We had read the side effects but thought we would try it against our better judgment or instinct because he's had reoccuring asthma attacks and honestly, we were getting tired of watching him go through breathing treatments and spending hundreds of dollars we don't have on his medicine. His Pediatrician told us that Singulair was safer than Zyrtec and that he personally has had only one child have side effects. After 7 days, our son wound up with an ear infection. Normally, he would complain a little and he's normally a great kid even when he's sick. He's the model patient. With this particular ear infection, he's become insecure and scared and he had several crying spells that lasted over an hour each time. He's been incredibly moody and out of the blue starts to yell that no one can speak to him, that it's "scaring him and hurting his feelings"....??? WTF? We stopped the Singulair to M 4 7 days

 1  Asthma/Allergies Nothing at first, then hallucinations with sounds followed by bad dreams; finally he couldn’t sleep alone. My child acted as a normal 3-year-old, so at first I didn't suspect Singulair. Then after taking it for a few months, he was afraid to be in bed alone. Now recently he can't even sleep by himself. After reading other kids' reaction I decided to take him off. Please research the affects before giving a child ANY medication. M 4 8 months

 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 My 4 year old was put on it for seasonal allergies. I am a RN and was careful to give it only during those peak allergy weeks in the spring and fall. I did know about the side effect of behavior changes and monitored her closely. This is the second spring she has been on the drug and in the past few weeks, I have seen pretty dramatic changes (i.e. temper tantrums, bad dreams, crying for no reason) As of last night, she is off the drug. It did not seem to improve her nasal drainage or cough. No worth the side effects. F 4 1 months

 1  Asthma/Allergies/ Eczema Anxiety, mood changes, whining, change of personality, aggression My now 5 yr old son has has asthma since the age of 13 months, and was put into Singulair. It was like a wonder drug it seemed to help in every aspect of that drug. I was quite happy with the drug. He lives with me (biological father) and has little to do with bio mum for her own personal reasons and hasn't since he was 3 and I had not noticed any major affects of this. Yes environmental factors do tend to do this to kids however since he started taking Singulair he changed completely and he was not the child I knew. I took him off it after reading this site and he has gone back to his "normal" self. He no longer suffers from anxiety. He is your average 5 yr old child going on 25. I wouldn't recommend this drug to anyone to use, esp kids. I haven't a clue how it affects the adult brain, but for a child it's a no no. M 4 3 months
