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  Asthma Fatigue, cluster headaches, concentration problems, weight gain, moodiness, leg cramps. Worked well for reducing asthma symptons. Was diagnosed with environmental asthma 4 years ago. Given a six month course of corticosteroids and started on singulair and an inhaler for attacks. Started putting on weight almost immediately with no lifestyle change, increasing exercise levels did not help. Weight kept going up every year even though I exercised more and more. I was doing college courses and my work requires reviewing documents and I found it extremely hard to concentrate and focus, mood swings were incredible (I blamed it on stress at work). After reading this site, I figured I would try going off it. Almost immediately concentration levels returned and not tired all the time, weight started dropping (no lifestyle change again). Stand by when going off, I had some bad nights and sinuses went crazy for a few days. But I feel like a new person, mood swings went away. Thanks everyone! I will go back to short term OTC/other options and discuss with Dr. next visit. M 45 4 years

 1  Allergies Nightmares, sleeplessness, anxious, extreme exhaustion, stomach ache, depression, sore throat, palpitations, tightness in chest, couldn't think clearly, couldn't express thoughts, ringing in the ears I have allergies that trigger horrible migraines. The first five or six years that I took this med I seemed to have no problems. Gradually something changed. I couldn't sleep without horrible nightmares, and I was too exhausted to get out of bed when awake. I would lie in bed almost paralyzed, but my mind never,ever, ever shut off. Exhaustion became so bad that I couldn't carry a laundry basket upstairs without having to stop three times and lie down for a few hours afterward. I finally wound up hospitalized for a week so they could drug me to sleep. I didn't take it in the hospital and got a bit better. I went home I started taking this, along with other allergy drugs, again, because my doc thought it was such a benign wonder drug. My symptoms all returned and I struggled for months. I had tons of tests at several different specialists to try to figure out the cause, but all was normal. I was in such a bad state after a year, desperate, I eliminated all pills, one by one. This pill was the last thing to go, because we thought it was the least likely to cause a problem. I was off it and doing much better for about 2 years. Just last week my allergies got really bad again, so doc convinced me to give this another try. I agreed, but only at a very low 2.5 mg dose to try it. Within three days ALL of the symptoms returned with a vengeance! All those years wasted and I never put it together until now. F 45 9 years

 1  asthmatic bronchitis difficulty falling asleep, waking after 2-3 hours feeling as if I was coming out of anethesia,tightness in throat,paranoia,nervousness, anxiety,nausea, feeling like I was going crazy This drug caused me to have not only difficulty falling asleep but I woke each night from 2-3 hours of sleep as if I was under anethesia. The skin on my face felt numb and it took a long time to become oriented and force myself awake. It felt as if I were in Alice in Wonderland. Then I could not sleep. I was taking other meds that I have been cutting out, assuming they were the problem but last night Singulair was the only med I took. This has been one of the most scary experiences of my life, I have slept 9 hours in 4 days but last night was the last Singulair I will ever take and I pray it works it's way out before tonight. F 45 8 days

 1  exercise induced asthma diarrhea, constipation, stomach cramps, depression, anxiety, anxiety attacks, suicidal thoughts Quickly determined that the daily diarrhea and other gastric symptoms were due to taking Singulair, but thought I'd wait it out and see if it went away. However, after reading up more on this medication, I realize that my anxiety and depression were not due to other circumstances in my life that are going on concurrently. I am a strong person mentally and can deal with problems. But I actually had suicidal thoughts twice and that really scared me. So I'm tossing this medication in the garbage tonight. I'll stick to my inhalers, thank you very much. Can't wait to detox this medication out of my system. F 45 22 days

 1  Allergy I went with my 4 years old daughter to a pediatric allergist due to her pediatric found problems in a blood test. The allergist prescribed Singulair 4mg, Allegra and Nasonex spray. About 4 weeks later started an allergy in her body and their pediatric said it was an Urticaria (hives) due to the food, after several test she was hospitalized for a week a received a lot of steroids and a the diagnostic of allergy to the wheat flour, eggs and cow milk with a very restrictive diet. The recipe to our home was continuing Singulair, Allegra and Zyrtec. The urticaria come back again, her lips get very red, mild fever, sweating, heat in your body and the urticaria changed to a big problem, the leukocytes count down for about two weeks. To resume this "medical enigma", and after several weeks almost desperate thinking in everything as possible cause, my wife and i stopped the Singulair and Zyrtec (the urticaria started before of Zyrtech) and in this moment we have two weeks without urti Don't Give Singulair to Your Children!

 1  Asthma Severe Headache I took this med years ago and never had such a headache like I had when I took it for 1 night. Ice and tylenol would't help. I had a severe headache for 8 hrs. When I took it years ago I had to stop it after a month because of severe nausea, no headache. F 45 1 days

 1  Asthma Unable to sleep. lay awake on bed, drifting, vivid dreams and nightmares I have difficult to treat asthma- mostly because I'm allergic to most medications. The doctors decided to try me on the child's dose. My first dose, taking in the morning, allowed me to sleep at night somewhat but gave me horrible dreams. Dreams that had my heart racing and awakening from my bed scared. When I took it at night, as suggested for Asthmatics, I never slept. I got about 3 hours of sleep last night, due to this medication keeping me awake. It did however help me with my asthma... F 45 1 days

 5  asthma/sinusititus None Prior to using Singulair I was having sinus surgeries approx every 18 months. No surgeries needed since and my sinuses are gerat all the time (wow!). Singulair also allowed me to reduce my inhaled steroids to the minimum levels - asthma flares now only occur when I have a respritory infection. M 44 3 years

 4  asthma Terrible abdominal pain and constipation. Two visits to the ER, 2 cat scans and a hydoscan later, and I suddenly started to think about this drug, and how the terrible constipation seemed to have started near to when I started taking it. NONE of the many doctors I've seen---my regular doctor, the gastroenterologist, the surgeons---ever considered it could be the singulair. Now that I've read on this site that several others have experienced the same side effect, I'm going to stop it and see if that's the culprit. I'll be sorry to have to stop it, because it's been very helpful for the asthma and I've had no other side effects. F 44 3 months

 4  Repeated Pneumonias, Asthma So far, this medication has helped my daughter with her asthma. Not one puff on an inhaler since she started it. She had TERRIBLE side effects from inhaled and topical steroids for pneumonia prevention and eczema. The depressed moods, suicidal talk and meltdowns were contant. On THIS medication, she has an occaisional meltdown, but so far, much more manageable. No more suicidal talk and self-injurous behavior, no moe bed-wetting. I have noticed that she has become a constant sensory seeker. She flips on and off the furniture and asks for a bear hug at least 2 times and hour. She has been enrolled in gymnastics because of this and LOVES it. I have reduced sugar, dairy and gluten in her diet to help with the eczema and general inflamation. I aslo give her EFAs (Essential Fatty Acids), vitamin D, a multivitamin with a probiotic, and extra zinc at signs of a cold. So far she has done well, health-wize. She is aware of what the steroids did to her and feels comforted in knowing F 44 3 months

 4  Allergic Asthma from Pollen I take this pill when I have a bad exuberance of my allergies that causes allergic asthma symptoms. It controls everything but I only stay on it for 2 1/2-3 weeks because it does cause anxiety to increase. I take it at night cause after about an hour your so sleepy. Sometimes the drowsiness lingers into the morning. Other than that I take a break in between to get through a high pollen and grass count spring. Drink a lot of water and hot tea. Take at night. Don't take for long period of time. Go off and on to decrease anxiety and mental health issues. F 44 14 days

 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.
