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  allergies insomnia, hallucinations, and dream abnormalities My daughter was prescribed Singulair at age 3. One night DH heard her talking to herself in the middle of the night for hours. When asked the next morning who she was talking to, she said, "The people in my walls." Her waking up and talking all night went on for about 6 weeks. Daughter is now 6. I mentioned giving her Tylenol for a toothache the other day, her response was, "Wait, is that the stuff that makes me see my dreams on the walls?" Connected the dots and realized that she had been hallucinating that whole time. F 3 2 months

 1  asthma Nightmares, suicide ideation, hallucinations, threat of violence to others, severe headaches, pain in joints, depression, reckless behavior, anger/hostility/aggression, fatigue. Do not take this drug! It is poison. There are other, much safer, alternatives. Contact FDA, contact Merck, contact all your health care providers, contact your school counselors, contact the press, tell everyone you know. This is Merck's biggest money maker. This drug should not be given to children! F 11 24 days

 2  Asthma My daughter takes it... she is 4 years old and has asthma real bad. the side effect that ive noticed 1). really cranky ( she cries a lot) 2) mood change with in seconds. ( she actully slaps her older brother.) 3) complains of tummy ach. 4) Stops breathing at nigh time.. Theres not one night that goes by that i get to sleep alone. because im afraid she will stop breathing. Every since she's been on singulair i've noticed at night that she stops breathing. i have to set her up right to get her to breath.. Its very scary. I read a lot of comments about the meds but didnt think anything of it... tomorrow we are going back to the doctor.. Something just isnt rite. Shes always in a bad mood, and sometimes she hits on her brother (older then her) which isnt like her. And also she tryies to hit me. I hope there is something else we can try because Singulair isnt it.... F 4 1 years

 1  asthma very violent behaviour, uncontrollable crying, hallucinations, angry about everything and everyone, panic attacks, anxiety legs itching, abdominal pain, potty accidents After Singulair I stop recognise my child that was the worst thing I did by giving her this drug. She didn't had side effects till about 5 month from starting the drug and I thought that she is "save" I was very rong. I did my research about Singulair before she started taking it and I knew all the side effects but I was thinking this won't happens to me but it did happen.I'm hopping that she will be ok and I will have my little girl back. When I ask her why she is behaving this way she always tell me " I dont know" and that is hart braking.SINGULAIR SHOULD BE BANNED!!!! Don't take it, I will naver give this to my child again.

 1  Son was taking for allergies My 5 year old son had severe allergies and was prescribed Singulair. I asked the doc about side effects and she said there were none that she knew of. I believed her and didn't do my own research. He has had unexplainable mood swings, happy one minute and hitting himself in the face the next. Saying he doesn't like himself. Nightmares. complains of stomach pain and headaches. I thought he was just having behavior problems until I got curious and read the ratings about this drug. I'm shocked that this is prescribed to children! I will never give him this drug again or trust his doc! M 6 1 years

 1  Asthma and Allergies My daughter was just put on Singulair for her Allergies and Asthmatic cough. Her allergist put her on this to see if it might help her I was very hessitant to give it to her but after seeing her suffer today I decided to give it without having time to sit down and read about the side effects. I am so terrified right now I think I am going to spend the night sitting next to her and watch her very closely. My heart goes out to all those parents who have had children suffer with those horrifying side effects. I cant believe something hasnt been done by the FDA to pull this drug from use of children. My nephew was also on this for a year for allergies when he was two after a year of taking them he stopped now he is 7 and he still has nightmares, cant sleep through the night, compains about voices he hears, extremely sensative, talks about killing himself at times, etc. Does anyone know if this might be a side effect from the drug after so many years?

 1  Allergies My daughter's psychiatrist warned me that this medication may cause behavioral problems and I didnt believe her. My daughter had taken it the year prior with no problems. However, this year, my daughter started taking it and after two consecutive weeks she was showing aggressive behavior, stomach pain, anxiety, and sever frustration overall. She gained weight in the two short weeks she took it. I am shocked. I have had my son on this medication for over 6 years without any obvious issues. I am however taking him off after learning of all the problems that have started coming out about this medication. F 8 2 years

 1  Asthma Anger, bedwetting, fighting, itching feet, sleep walking, bad dreams My son has been on Singulair for 3 years now. He has been moody, angry, wets the bed, fights with his sisters, and is rude. His feet will itch him so bad that he wants to cry. He will say that nobody likes him and that everyone is mean to him. He will wake up crying and say that he had a bad dream. At times he will sleep walk and become aggressive if we try and put his PJ's on him. We thought he had an anger problem and were going to take him to the Dr. to see if he needed depresssion meds. I am a RN and never even thought it could be from the Singulair. I am sooooo glad that I found this site! I told my son about it and he is so happy that this could be the answer to his anger. When asked why he is angry he just tells me that he doesn't know. This med did help his Asthma but he will never take it again. I am ready to have my child back. M 8 3 years

 4  Child asthma none that were noticeable, wondering if there are long term side effects?? my 3 year old developed severe asthma symptoms and was repeatedly being admitted or rushed to hospital with every cough and cold, which was being made much worse by the fact he has respiratory problems. The preventer ( steroid) inhalers were not making a difference and the reliever inhaler was giving him an increased heart rate ( very common side affect of reliever inhaler) and made him hyper and feelings of extreme hunger. Singulair was prescribed and within two weeks has changed my sons life, from virtually being unable to walk up stairs to being able to run around and he almost never gets a cold now!! The mmr vaccine has given him more terrible side effects than singulair!! M 4 7 months

 1  Asthma & Seasonal allergies I was truly at my wits end with my 7 year old daughter. Her behavior at home was horrible. She'd come in the house from school miserable and fighting with everyone. I felt myselt begining to get nervous as the bus was coming up our hill not knowing what to expect from her. Since we started her on this medication when she was 3 or 4 I was beginning to think there was something "wrong" with her personality. We switched allergy doctors solely b/c our previous DR relocated. The new MD took her off singulair and increased her pulmicort does. I immediately noticed a difference in her disposition, attitude and behavior. We go back in 1 mos for another lung function test. Hopefully it's good but if not I will be looking for other options to relieve the symptoms. We won't be using singulair again. F 7 4 years

 1  Son taking for allergy management Just now taking my 6 year old off of Singulair, despite Pediatrician recommending continued use. Within the last month, he has become extremely agitated, grumpy, weepy, miserable. Complaining of stomach aches, very tired, not a happy camper. I strongly believe it's the singulair and will not put him or my other children on this medicine again. Seemed to work fine for the first year of use. Did seem to help with asthma/allergies for a short time, then the effect seemed to lessen and the side effects worsened. M 6 2 years

 1  allergies and asthma severe anxiety, hallucinations, unable to sleep due to terrifying dreams, self-harm behavior, sadness, agoraphobia, separation anxiety My son has been on Singulair for 4 years now and is 4.5 now. On April 22, 2011, he developed severe separation anxiety, agoraphobia, hallucinations, severe sadness, self-harm behaviors, and difficulty sleeping due to terrifying dreams. Over the course of three days we were in the emergency room 3 times due ot this behavior. On the 3rd emergency room visit, he was admitted to Helen Devos Children's Hospital. Doctors were baffled at his behavior using Ativan, Versed, Haldol, and Risperidone to attempt to help. We had to put restraints on him as his symptoms increased in intensity to keep him safe as he was trying to bite off his fingers, scratching at his skin, and banging his head. He had brain scans and an EEG. He was seen by neurology, psychiatry, infectious disease, toxicology, etc. After being hospitalized and with no relief from the anti-psychotic medications for 3 days, a psychiatrist found infomation on the internet about psychosis in children who were taking Singulair. With no answers yet, and nothing else to do, she tried taking him off of the drug. With in 3 days, he was back to normal, and happier than ever. He's been off the drug for 12 days. He has had 3 episodes of anxiety attacks since then, but nothing like he had in the hospital. Are you going through this too? PLEASE contact me! M 4 4 years
