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  8 months Singulair 10 mg tablet is scary, the drug was helping my breathing while I was continuing using it but I wasn’t ok at all which I did not notice about the reason of side effects, and I just figured out that around 15 days since last dosage after 8 months of using 10 mg, I had hard breathing, headache, Feeling nausea, insomnia, sleepless, little shaking left hand, diarrhea , and a rapid of fast heartbeat but the big problem was my the mental issue, so mood changed negatively and has depression and anxiety. However, after the hard time visiting many doctors to find the problems, I found that after reading people experiences over multiple websites it’s the singulair plus it returned me back to past around 5-6 months ago when I was stopped taking singulair for one week, I remembered I been to emergency had headache, insomnia, chest problem till I took it again once a day before sleeping which made me not ok. I am not Recovered a 100% and still having hard times but for sure I will be ok very soon. Not recommended at all it’s not worth it plus asking qualified dr is important. Stopping and using can cause series side effects. I’m better but I believe withdrawal will take time since I am daily improved from the day I quit turkey. M 30 1 days

 1  for asthma and allergies I was prescribed singulair about two years ago to help control my asthma. After a few weeks, I noticed I was not feeling like myself. I was increasingly anxious and angry. I just felt down and negative about my life. I distinctly remember the day I figured out it was the singulair causing my mood issues. I was standing in my kitchen thinking about what to make for lunch when I became so angry I was physically shaking because I realized that my husband had eaten the last of the leftovers. I knew this was not a normal reaction, and I've never had anxiety or anger issues before or since. I stopped taking the medication and told my doctor, who shrugged it off and said there was no evidence that this drug caused my anxiety. I can't believe they prescribe this stuff to children :( Take it off the market!!!! F 30 3 months

 1  asthma hyperactivity, aggressiveness, irritability, anxiety, agression Ever since my 4yo was put on Singulair 4 months ago he was a terror. Took him off, in period of 2 weeks things slowly started getting back to normal. The terrible side effects he experienced were not worth taking the medication. I would not reccommend Singulair to anyone. F 30 4 months

 1  Allergies Not sleeping, complaining about legs hurting, nasty attitude, hateful, mean, crying, hallucinations (after a day of the medicine) My almost 3 year old daughter was given this for allergies and back to back sinus infections. The medicine did help with the allergies and runny nose, but the side effects were far worse. It was over night my daughter went from a sweet girl to a hateful little girl - I thought I had done something terribly wrong somewhere down the line. Now after reading all these comments I know it was the medicine without a doubt. I had a gut feeling about the medicine she was on, so I stopped - overnight her mood changed - sleeping is still a little issue, but at least her sweet self is back - I have my daughter back!

 1  Seasonal Allergies The side effects that I have read about, are exactly like what my 2 and a half year old daughter has been going through. I put her on it almost 2 weeks ago and noticed a drastic change in my child. She woke up totally freaked out with a nightmare @ 1st...then it progressed. Her behavior has become EXTREME and it's very hard to communicate with her...she acts (seriously) like a mental patient with a crazy look in her eyes half of the time. She will NOT go to sleep in her bed like she used to and has become so upset when we tried to put her in her bed that I thought she were going to pass out or have a seizure....she stopped breathing followed by blood curdling screams. The following day she came up to me and head butted me in the nose...not an accident. I had started to feel like I had lost my once sweet little angel to a horrible mental illness. Then I remembered my Dr. telling me that if I notice any "side effects" to let her know and stop treatment. Side effects....I'm thin Do the research! F 30 2 weeks

 5  Allergies, Allergic Rhinitis I had no side effects from this medication that I know of. This worked great for my environmental allergies. I had allergies so bad my glands would swell and I would ache like I had a mild cold. Since taking this my allergies have been greatly under control. I take it probably 9 months out of the year, excluding the winter when everything outside is dead. My mom and dad also take this. My mom is 53 and has no side effects. My dad is 54 and said he had weird dreams when first taking it but nothing since. M 29 3 years

 5  Asthma Myself-None Daughter-None I am 29 years old and had been on steroid inhalers since I was a kid. I have been on Singulair for a year and after a month I found I did not need the steroid inhaler anymore. I take a 10mg a day and 10mg loratidine and it is like I do not have Astmha or allergies. My 5 year old daughter was diagnosed with Asthma last fall and has also been on Singulair since. I have not noticed any side effects in her. Of course she expresses dark thoughts sometimes but who doesn't. Most of the time she is happy. Even if I found it was causing mild depression I would probably keep taking it; it is so great to live without asthma and without the side effects of the steroids. M 29 1 years

 5  Severe asthma None whatsoever! This is a miracle drug if you have severe asthma! I've been on it for 2 years. The past 1 year, I don't even have to use daily inhalers as prevention like Serevent and Flovent! I have my life back thanks to Singulair! F 29 2 years

 3  Chronic Sinusitis/Rhinitis insomnia; dry mouth Pros: very effective at treating my chronic nasal passage inflammation and allows me to breath through my nose at night Cons: I am getting 25-50% of the sleep that I used to. I cannot keep up with a lack of sleep, as has and will start to further impact my daily work. M 29 1 weeks

 3  Asthma and allergies My almost 4 year old has had issues with ear infections and breathing since birth. He began taking Singulair about 4 or 5 months ago when our ENT suggested that he had his adnoids removed and I decided to take him back to the pediatrician to discuss it first. After reading all of the comments posted, I am beginning to wonder if all of my son's behavior that my husband and I have noted in the past few months is attributed to it or to something else. I am going to stop giving him Singulair for 2 weeks to see if his behavior changes. I hope that is long enough to get it out of his system. If anyone has any feedback, please share. F 29 6 months

 2  asthema based on allergies The first two weeks - nothing. Now I am exhausted. Mind keeps racing but body feels weak. No motivation to do anything and groggy throughout the day. Stopping this medication immediately with hopes that a normal life will come back. I will gladly resort to my inhaler. I haven't had to use my inhaler since I started it. However, the trade off is not worth it. I want my life back. F 29 21 days

 2  Seasonal Allergies I gradually changed. I used to get out of bed like a pop tart and am always on time for work. I eventually didn't want to wake up in the morning, didn't care if I lost my job and would cry all the time for no reason. I finally got to a point where I was driving in my car thinking about running my car off the road into a wall doing 80 on the highway. I just wanted the sadness gone. I am stopping this medication today! It did clear up the constant runny nose and itchy eyes. The sinus pressure was mostly gone, but I basically thought about sleeping or killing myself all the time about 4 weeks in. F 29 6 weeks

 1  Asthma Depression, moodiness, extreme sensitive, weepy, anxiety, muscle ache, hard time focusing, very tired but could not sleep, when able to sleep vivid dreams that fell right in with my depression and sensitive. This is sad for me. The drug did wonders for my asthma. I had no use for the inhaler since I started but then one day at work Depression and extreme sensitive just hit me like a freight train. I had to take a 30 min break because I was scared and shaking so bad I could not work. Glad it was Friday. I continued taking it over the weekend and was ok. Then on Monday it hit me again and I was barely able to finish my day. Monday night was the worst I couldnÆt sleep and when I did I had dreams that scared me. In the course of 6 hours I woke up about 20 times. Tuesday I left work early and went home to rest and play with my children and couldnÆt keep from crying all day. That night I stopped taking it and prayed that it was the problem. I write this on Thursday feeling significantly better now. I can work and am only slightly down and sensitive. I like the drug but the depression and sensitive is too much for me to handle. M 29 14 days

 1  Cough, asthma Increased anxiety, restless sleep, headaches, stomach aches, despondency/depression, suicidal thinking I've always been a very solid, happy person with very predictable moods. Since I started Singulair, I became increasingly irritable, but I shrugged it off, assuming it was work related. I've also felt confused, dizzy, and absent-minded. Within the past two weeks my anxiety has been higher than ever, and I became listless. Everything felt so dark and so hopeless to the point where I thought I needed to be checked in to a hospital and treated for severe depression. I have never, ever experienced that type of thinking in my life, and luckily that's when I stopped and took a look at my medication's side effects. I was shocked to read these testimonials, and I'm certain that Singulair is responsible. F 29 4 months
