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  Exercise Induced Asthma, Allergies Depression, Anxiety, Suicidal thoughts, insomnia, loss of appetite, and many more Once I started taking it, I got the side effects pretty quickly. Now, I cry every night for no reason and have really bad thoughts that I can't control. I barely sleep at night; Going to bed almost every night around 4 or 5 in the morning and sleeping throughout school which is causing my grades to drop. My friends notice my mood always changing. Sometime, I get random attacks and break down crying and not wanting to talk to anyone. it's only been 3 weeks and I hope it doesn't get worst because I don't plan on stopping. F 15 3 weeks

 2  seasonal asthma from allergies depression, mood swings, anxiety I took Singulair last year when i was 14, and it was a 5mg pill. I had a lot of anxiety and ADD like symptoms, i couldn't focus in school and my grades had a drastic drop. The anxiety and depression like moods would switch off, where I could go from being running around anxious one second to sitting just wanting to be by myself the next. This year I'm now 15, and so the dosage was upped to 10mg. I didn't know this, and so I started taking it again hoping there would be no side effects. It was so much worse this time, I started having panic attacks and crying spells and wouldn't know what to do with myself. Singulair does help with my allergy and asthma symptoms but I think I'm going to stop taking it because of the side effects. F 15 1 years

 1  allergy irrability, focus on suicide, self harm, change in mood, nose bleeds We have a 16 year old son, who has no history of depression or unhealthy ways of coping. Started a downward spiral, we did not know what was going on. He could not explain it,"I don't know" Took him to counseling for help, they did not have an answer, or see something we couldn't. Read an article on singlair, and was outraged and shocked, never Knew there was a possible connection. Stopped the medication. Waited... THe next day, our son was back. Each day was brighter and brighter. Would not have believed it, unless lived it. Have it documented by counseling as well. Hoping to follow up with someone who can get the word out. Our son's life was saved, and we would like to help others. Thank you M 15 1 years

 4  asthma & allergies None that we are aware of. My 14 year old daughter has been taking Singulair for about four years for asthma and allergies. She had a life-threatening event 1 1/2 years ago and was resuscitated at local hospital and transferred to regional children's hospital. The event, which is believed to have been "Sudden Asphyxic Athsma" had come on very suddenly while we were at a family event, luckily near the hospital. Prior to this event she had not been regular in taking Pulmicort or Singulair and had been relying heavily on albuterol emergency inhaler and Benydryl (which makes her very sleepy). She now religiously takes Flovent twice a day and Singulair 5mg and carries an emergency epi-pen at all times. She seldom needs the emergency inhaler and almost never has itchy eyes and hives, even though her blood work shows a very heavy allergic load. Either the Flovent works for everything or a combination with Singulair is working well for her. The allergist changed the children's hospital's RX back down to F 14 4 days

 2  Allergies Daily Headaches, Moodiness, Lethargy, Fatigue, Loose Stool, Loss of Appetite, Anger, Defiance, No Motivation, Sleeping problems (although it could be my insomnia associated with my arthritis, but most likely, its the medication) Like many other users, I want my life back. I have been experiencing way too many side effects and it really sucks. This medication has effected my life too much in a negative way and I'm tired of it, I am definately stopping tonight.

 2  allergic rhinitis (pollen, dander) My pediatrician had prescribed me singulair after many OTC antihistamines and prescription nose sprays (ex. Rhinocort, Flonase, AND Nasonex) had all been ineffective to my pollen and animal allergies. I had been making it through the 14 day trial period just fine until the last day where I broke out in hives. I was quite disappointed because until then, the singulair seemed to be working just swell. :( I didn't experience any of the mood changes, vivid nightmares, ect... Like others have been saying. I'll I would say is be careful what you are giving to yourself and your children. ~Nanners~ F 14 2 weeks

 1  asthma and allergies severe anxiety, hullucinations, paranoia, severe mood swings. Started taking this in 4th grade, worked great for my allergies and asthma, however when the dose was upgraded to 10 a year later I started getting hullucinations, was very paranoid and scared. I took the medication on and off for five years so there would be times I would be fine then I would start in with major anxiety, fear, afraid all the time that my mother was going to die, unable to do anything away from her. My mother asked the doctors if these symptoms could be related to Singulair and they just dismissed us and said no. My symptoms got so bad I was given prozac and xanax, which didn't help. Then we found this site and stopped taking the medication immediately. That was two months ago. I'm almost free of the anxiety, not completely symptom free but feeling MUCH better. I'm able to go to school and even out occasionally with friends. This medication works for the allergies and asthma symptoms but not worth all the horrible side effects. I wish there had been better warning labels when I started this medication, I would have stopped it immediately back in grade school and I believe my life would have been much different. M 14 5 years

 1  Allergies My teenager was on this and became severely depressed on it (no prior history). Took him to his doctor and she said she had never heard of this as a side effect. Said if he didn't snap out of it, she would put him on an antidepressant (which I am totally against). Took him off the Singulair and he returned to normal within a few days. I find it interesting that now there are reports of this drug causing depression/suicide. Glad I didn't listen to the doctor and knew in my gut that this drug was making him feel this way. Watch your kids carefully while on this drug! M 14 7 days

 1  mild asthma mood swings, anxiety, depression, aggression, outburst behavior, nightmares, diminished impulse control, suicidal ideation My daughter went from a delightful little girl to a problem child almost immediately. That was blamed it on the fact that she was nearing her preteen years, though she didn't reach puberty until 14! When she ran out of the medicine recently I didn't renew it, and her behavior is rapidly reverting to normal, though her self esteem had been damaged by the years of ADD-type behavior. F 14 6 years

 1  exercise-induced asthma 14 yr. old boy - nightmares (never had before), major problems concentrating in school, esp. math (an honor student), said he felt "wierd" and "different". My 14 yr. old son was put on Singulair for exercise-induced Asthma. He has no other asthma problems. Within a week, he was waking up at night with nightmares and had trouble sleeping. He has never had dreams at night. He said he felt "weird" - kind of in a fog. Another problems he had was concentrating and focusing on his school work. He is an "A" honor student and had trouble focusing and rememebering things. We really noticed it with his math. We took him off Singulair and have already seen a major improvement. Just be careful and be sure you monitor your child. It did not work for us. He said that it did improve his breathing during basketball but we are looking for other options - not worth it for the side effects. M 14 14 days
