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  Severe allergies Anxiety,anger,depression,insomnia,weight loss,palpitations,decreased energy. Having suffered from severe sinusitis due to allergies for 30 years, having used cortisone sprays, pseudo ephedrine with little effect I discovered Singular and researching that it blocked receptor that causes allergic reactions I thought I would give it a try. Yes it was great for allergies but the side effects were dangerous. I actually thought I was going to end up in a mental hospital. I do have a very busy schedule, but I was unable to cope with anything. M 54 30 days

 1  Sinusitis The drug was great at eliminating nasal congestion and reducing my cough but only one pill kept me wake. I took the pill the first day in the morning. At 4:00AM the next morning I was still looking at the clock. I also felt disconnected from myself. After only one pill I realize I can't tolerate this drug and will not ever take it again.

 5  Chemical intolerance to fragrances I did not realize I had side effects, but looking back after reading patient comments I realize that the insomnia and irritability, greatly reduced tolerance for stress, etc., may well have been side effects of Singulair. When I suddenly stopped taking Singulair the first time after about 8 months (because I left the environment that was causing my original symptoms), after a few days I developed truly crippling lower back pain, like a muscle spasm at the top of my hip bone. Was flat on my back in agony for a week. I recently started taking Singulair again, took it for 3-1/2 weeks. Then, after leaving the environment that caused the allergic reactions, stopped again. Now, a few days later, the muscle pain is returning with a vengeance. This time, I put 2 + 2 together and am fairly certain that this is due to sudden cessation of the medication, as I have never had back problems before in my life (55/f). Also, after reading all the comments on this and another site, am wondering i F 55

 3  Asthma, SOB Horrendous depression and crying. Really bummed about this because it's helped my asthma and shortness of breath a LOT. But I don't know how I can tolerate the depression much longer. Does it eventually go away?? I don't like the fact that the chewable tablets contain aspartame, a sweetner that many European countries have banned due to its own bad side-effects - tumor excelleration and short-term memory loss among them.

 3  Allergy and asthma Weight gain, bad dreams, hard to stay asleep, anxiety. I take this sparingly due to side effects. It does help me to clear lungs but I do gain weight without any eating changes and more exercise due to bike season. The drug is the culprit even though big pharma will tell you differently. Thanks to this site for allowing us to post how we really feel on medication. Any way, I started having bad dreams and wake up at 4 in the morning with thoughts and anxiety. When I go off of it , I get better and weight returns to normal. F 55 3 years

 3  asthma, allergies Over the time on the med, anxiety and panic increased til I was prescribed anti-anxiety meds, bp meds, and sent for heart workups on tachycardia and stress-related heart issues. At no point did my doctor consider the source as Singulair. Within one week after stopping Singulair, my anxiety disappeared and my wife noticed me calm w/o my telling her I had stopped the drug. Now that I am one month "free", I can relax with a book and enjoy sitting looking at the countryside, instead of being "antsy" and anxious. I have resumed having some morning nasal congestion and occasional (1/week) asthma at night but it's a very worthwhile trade-off. M 55 4 years

 3  Asthma & Allergies very tired , lack of interest in things that usually please me, mood swings , depression , indecisive unfortunately it helped with my allergies--it also gave me back my sense of smell that had been gone for years but it's not worth the side affects---------I'm stopping today and will report back after a week or 2 with an update-I hope to back to my old self---keeping my sense of smell would be a bonus!

 3  Wheat allergy Good for wheat allergy 2008-2013. Went off inhaled steroids and albuterol. Had gradual but increasing anxiety, memory loss, cognitive loss crippling back pain, and muscle weakness. Self-discontinued 2 years ago. All side effects slowly improving. Must avoid wheat and most "gluten-free" baked goods to avoid asthma. F 55 5 years

 2  To prevent nasal polyp regrowth Was prescribed Singulair following sinus surgery as a precaution to prevent polyp regrowth (this is the third surgery). Began taking on 2/02/07 and have become profoundly tired, wake up, eat breakfast and want to go back to bed. No motivation for anything, have never been "depressed" but the symptoms are as such. Go to bed at 6 pm and sleep till 7 am and still am exhausted. Have no appetite and frequently think about death. Will continue the two month program set by my surgeon but will never use this drug again. M 55 15 days

 2  mild asthma extreme anxiety, sadness, wake up in middle of night, crying without reason, belligerent, aggressive, mood swings This medicine worked well for me in the past. I would take it only in the Fall, when my asthma usually bothers me. I liked Singulair because it nearly eliminated my need for an inhaler. However, this year I began feeling side effects after about one week. They were severe enough for me to seek an appointment with a mental health professional. My wife thought I should research the drugs and herbs I am taking, then I found this website. No more Singulair for me! M 55 3 years

 2  allergies none that I noticed for sure. Mouth sore problem resurfaced, but not sure if its related to Singulair. I mention it just in case. Possible weight gain. Worked in the garden non-stop all weeekend. Usually I drop 5 lbs when I do that, but didn't past weekend. gained 1 lb. Pollen isn't too bad this time of year, but I guess I'm allergic to mold spores. The past 2 days have been rainy and drizzly and humid. I have been sneezing non-stop. I'm going back to Allegra. F 55 10 days

 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
