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  Allergies/flushing Deep muscle aches, joint pains, muscle cramps, pronounced weakness, poor coordination, mental 'fog', bruising. Darn stuff works like a charm. I was THRILLED to have found it, nothing helps like this does. But the side effects have become too much -- they have taken over and I've got no quality of life on the stuff. Too bad, for me.

 1  Allergies I have done nothing but cry and feel anxiety attacks for the past few weeks. Plus tremors and I haven't slept a decent night in over a week. I suddenly remembered a comment my Dr made when he prescribed it. "It might cause depression...but it is rare." I didn't expect any side effects because I rarely have problems with medications...but I think what I am experiencing is a side effect of this med. I cannot remember feeling so sad and hopeless in years...and the anxiety attacks are awful. I'm done taking this pill...back to benedryl for me. F 44 3 months

 1  Allergies anxiety,mood swings,severe depression, severe crying episodes,parnoia,insomnia, irritability,inpatient I began taking this medication for allergies. It took me a few days to figure out what was going on. I have been taking the same anti-depressant for 16 years and all of the sudden it was not working. Could not figure out what the problem was. One morning I was trying to figure out what was different and this medication was the only new med I was taking. I quit taking it and the symptoms began to subside and I have been off of it for 2 weeks and feel like a different person. I would recommend anyone talking to their doctor about any of these symptoms you are having. I am so glad I found this site. I thought I was loosing my mind! The brochure that you receive with the prescription did not have any of these side effects listed! F 44 1 months

 1  Rhinitis Lethargy, grogginess, buzzing in head, dizziness, horrible ringing in ears, poor sleep. I took only 2 pills and felt like I had been drugged. I would sleep for 1.5 to 2 hours, wake up, then sleep again. In the morning, I almost couldn't get out of bed. The head buzz was awful. I have a permanent ringing in the ears but it was about triple the normal volume. I took my pills in the evening. The day after my second pill, I eventually got enough strength to start exercising in an attempt to get the drug out of my system. It pretty much worked. It is now 2 days beyond that and I seem to be back to normal. Unfortunately, my rhinitis is coming back along with its attendant problems. It's too bad because the Singulair actually removed all of my rhinitis for those 2-3 days. However, it is not worth the side effects as they make me feel worse than my condition does in the first place. M 44 2 days

 1  asthma/allergies/sinus problems I have experienced headaches,weight gain,and severe swelling in both feet and ankles. My supervisor at work asked me if I had broken my left foot and not known it. My knees are also swollen and I have started experiencing lower back pain. As seems to be the case, my allergist does not feel the Singulair is the problem. I stopped taking all meds because I could not get into my shoes because of the swelling. F 44 5 weeks

 1  Allergies/Asthma After 4 days I felt as if I became extremely aggressive, agitated at everything and everyone, verge of losing patience at everyone, for no reason at all. This is not how I behave at all. Scary. Scary. Stay away from this drug. Also had insomnia, and even with a prescription sleeping pill had trouble sleeping, heart racing. awful. This drug is the worse drug I have ever been prescribed. Awful experience. F 44 4 days

 1  Rhinitis I am in the UK and was given this drugby my allergist. After taking it for 4 weeks, I began to feel very depressed and asked my allergist if I could stop it. She was quite bullying and insisted I stay on it, which I did. The last 5 months have been sheer hell! I needed emergency care from my GP after becoming suicidal (so bad that I was almost institutionalised for my safety), and was also now having varicella spots breaking out on my arms and side. My GP told me to stop the drug IMMEDIATELY! No amount of rhinitis symptom relief is worth the sheer hell I. have been through on this drug! F 44 5 months

 1  Chronic Rhinitis This is by far the scariest med I have ever taken. On the positive side, it did give a minor improvement to sinus and bronchial congestion, but the side effects were enormous: headaches, nausea, strange adrenaline rushes, muscle cramps/aches, insomnia, OCD, major depression, and probably 5-10 more I can't remember. After describing my symptoms to my GP, he told me to stop it immediately and throw the rest away. I did and guess what: all the problems stopped within about 1-2 days. As I said...scary.

 1  asthma I posted a rating earlier this week about feeling depressed, anxious and even suicidal while on this medicine. I have not taken the medicine for 3 days and the suicidal thoughts are completely gone. The last 2 nights I slept through the night instead of waking up numerous times. I am so glad I am off this medicine. My brother-in-law has taken Singulair for quite a while now and has not had any bad side effects. So it does work for some people. F 44 2 months

 1  asthma I was not to tell any difference in my asthma. However, my thoughts and emotions were greatly affected. I have been having suicidal thoughts and even planning it. I have been having terrible mood swings. I snap at the least little thing. I am glad I finally realize it's this medication. F 44 2 months

 5  Athsma/Allergies No side affects. I don't have mood swings or nightmares. Nothing. I started taking singulair because I would get so sick and my nasel congestion due to allergies 2x a year (fall/spring). What a difference. It's like I never get "colds" anymore. I used to feel I had a cold all year long, but after singulair I have no more colds. It's great! My life has changed. I used to loose my voice completely, and I have it all the time now. People should know that my allergies get worse with humidity/heat. When it's cold and very little humidity, I'm great. Unfortunately I still live where it is very humid. I also take claritin D with my singulair. I NEVER have to use my inhalers anymore!! These are the ONLY 2 drugs I take. If I forget to take them, I start with head aches and nasel congestion. Even people at my work notice if I forget to take them. I should mention that I get very tired if I DON"T take these meds. It's hard to breath without singulair and I get very tired. I'm definately more awake and alert. I have year-around allergies and exersiesed induced athsma. I'm also dyslexic. F 45 10 years

 5  Asthma Allergy testing came back negative but when I kept having cold weather induced asthma my doctor wanted me to try this. I'm already on symbicort & was doing good except cold weather. Well, the montelukestat helped it completely. We had a very cold winter this year & I was totally fine outdoors. Also I don't have any of the side effects some people mentioned, I feel great!!!
