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)

 2  Allergies & Asthma Depression & Anxiety Took Singulair on and off from age 13-16. I never really took the meds consistently until my sophomore year of high school. I was also depressed and anxious that year. I would break down crying twice a week to almost every day. I don't think it was 100% because of the medicine, but it may have contributed to the problem. I stopped taking it and the depression went away around the same time. F 18 3 years

 1  Protective med against flu sideeffe Violent aggressive n mood swings for my 2.5 yr old like I had never seen before. Would advice parents take an informed decision before using this drug for little kids who don't even know what is happening to them and rely on parents for everything. M 2.5 3 days

 4  allergies vivd dreams, minor drowsiness Singulair has worked really well for me. It really helps to open up my airways. I take it in the evening, and I only experience minor drowsiness. The vivid and unusual dreams are actually really interesting, so they don't bother me at all. I think people need to realize that drugs will work differently in people, so not everyone will experience the nasty side effects. I love singulair and plan to keep taking it. F 22 5 months

 1  allergies, ear infs, congestion Drug was very effective with no side effects until about 3rd - 4th month when I realized I had become depressed, anxious, irritable, easily agitated, and easily angered with no to little motivation which was very atypical for me. Could not find a reason for it. Kept forgetting to pick up my refill so I rationed the remaining pills, taking one every couple days for a week and then went without for approx 5 days. By the 5th day having no singulair, I suddenly realized that I was back to normal with no depression, anxiety, etc. Will never take this drug again and hate to think what condition I could have been in had I continued on it any longer. So glad I found this out purely by accident. Am amazed at the very negative side effects and never suspected Singulair as the cause. F 55 5 months

 1  allergies eye and neck twitches My son just started taking this medicine last Thursday. So, its only been 7 days and yesterday and today I noticed he would turn his eyes all the way to one side or the other several times and then stop. I asked him if something was bothering his eyes and he said yes but he couldn't explain what the problem was only that he couldn't help it and couldn't keep from doing it. He was only supposed to take for a month to get through the spring pollen season here. But, I'm not giving it to him anymore now that I realize the singulair is the problem. I asked him how long his eyes have been bothering him, he said it wasn't bothering when he went to the doctor, but now it is. He's only 12 and has enough to deal with just being in middle school. He says he's been sort of embarrassed by the problem. I hope stopping the medicine will end the side effects. M 12 7 days

 2  Allergies / Asthma My 8 year old son has been on and off Singulair for approximately 3 years. As far as relieving symptoms of seasonal allergies and asthma, it does a great job. At times, he has a difficult time with concentrating in school, mood swings, eye and head tics / twitches, crying at night, worrying about his grades, etc. I have noticed when we get off Singulair for a week or so, these symptoms subside. Not sure what to do!! There has to be another drug out there that has the positive benefits as Singulair without these scary side effects! F 38 3 years

 1  Allergies Within 24 hours, my even tempered 3.5 year old turned into crabby, crying, emotionally fragile child. He would melt down in tears and when asked what was wrong would say "I DON'T KNOW." He is usually very good at expressing himself, but since being on this, he is easily upset and confused. When he wakes in the morning, I'm telling him he doesn't have to take this anymore. I had a bad feeling going into this...no reason why as I had never really heard anything about Singulair (positive or negative)...I just had a bad feeling. I feel so terrible that my sweet boy has had such a difficult few days (major tantrums/meltdowns). He's 3.5 and I'm proud to say that I am always complimented on how lovely he behaves...not the last four days...poor sweet boy. I can only imagine it's the medicine. He has only been able to express that he feels bad all over, but cannot pinpoint an exact location. He said he felt fragile and very sad for no reason at all...scary stuff. F 3.5 4 days

 4  Allergies Vivid dreams but nothing horrible. I guess it all depends on what skeletons are in your closet. Seems to work fine. my 6 year old daughter has taken it with no side effects. As with all new medication theres a bit of anxiety about taking it. I see alot of bizarre psychological issues on this board like aggression and even masturbation but those sound more like behavioraly issues. Ive never seen a drug force someone to do anything any. Can it make you irritable ? sure, some may but Ive seen no side effect from it yet. M 36 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

 1  allergies head twitches/tics My son starting taking Singulair on and off since January. I started giving it to him REGULARY the last week of January til about a month ago. What he experienced/now experiencing was/is head twitches. It was like a twitch to the side of his head, all day long for a month now. It was a ped on call that asked if he was taking singulair and said that it was known to cause tics and twitches. He has been off for a month now and although the twitches has subsided they are still very-much-sothere. I plan to leave an update with hopes that I can help someone else out becuase I am claiming the victory over this medicine. To see my son go thru this has caused a major depression for me and has affected everything that I am involved in. But as I pray, I KNOW all will be well and that it will just take time for this drug to pass through his system. God Bless you all and I feel your pain. M 8 3 months

 1  seasonal asthmatic symptoms mood swings, night terrors, nightmares, anxiety attacks, agressive behavior I actually left a comment back in December about my 3 yo taking the drug Singulair. I wanted to update, because I know that responsible parents are checking these sites hoping to learn more about the medicine! My son was actually diagnosed with post traumatic stress disorder after only being on this medication for FOUR DAYS! The hallucinations he experienced while on it kept him from sleeping in his own room for FOUR months, and we actually had to switch his room to a different room, completely redo the paint, covers, furniture, everything. It was a NIGHTMARE. Finally, four months later, he is returning to his old self. We actually have switched pediatricians because she again prescribed Nasonex after knowing everything we went through with Singulair...sure enough, the side effects are the same. Parents, please take caution. These are adult drugs they are giving to children. M 4 4 days

 1  Allergies Son lost ability to concentrate. Screamed out nightly with night terrors. Normally an excellent student, but teacher called conference to discuss his lack of concentration. Doctor told me it was absolutely not the singulair, but when I took him off the medicine he was back to my normal child. Took son to allergist and he concurred that he had heard about these side effects with singulair. M 7 1 months
