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, sinus problems YIKES!!! I took it a few years ago and quit because of the insomnia and general agitation it caused me. Tried it again recently and this time I've got the previous side effects PLUS muscle spasms in back, ribs (intercostal muscles between ribs), and jaw. Scary. I thought I was getting TMJ, only to find the problem goes away if I stop taking Singulair. My back and ribs hurt so much I thought something was wrong with my lungs. This is too bad, all the muscle spasms, insomnia, and crabbiness, because the drug WORKS as far as helping me breathe better. Less wheezing, less stuffiness, but it's just not worth it. Looks like I'm back to Benadryl and grogginess. I'll accept that before I agree to anymore muscle spasms. ugh. F 51 3 days

 1  asthma Insomnia, muscle aches, daily morning headache, feeling like ants under my skin, irritability (extreme), fatigue not relieved by full night's rest, "brain fog", inability to concentrate on difficult tasks, swelling of ankles, rash on back and legs, dry eyes, dry mouth, extremely dry lips, always thirsty, tinnitus. I was on this med for five years, prescribed by pulmonary doc for asthma. I had been feeling increasingly tired, achy, irritable and fed up with life in general. I could not seem to concentrate at work and would make errors that I never made before. The swelling and itching and dryness was getting worse. I went to my GP and she told me I was going through menopause and was "depressed" and that I needed anti-anxiety meds. I refused to take the RX, and came home and started researching Singulair as I began to realize that the not feeling well had started the same year I was "diagnosed" with asthma. When I found this website, I knew I had to get off this drug. I have been off it for three weeks now, and I cannot believe how much better I feel already. I am praying that most of my symptoms will abate if I continue to clear my system of this drug. When my allergy symptoms get worse, I take Benadryl, makes me a little sleepy, but at least I don't have the "brain f F 51 5 years

 1  Allergies/Asthma Feelings of anger, depression,distance, exhausted, lack of focus and concentration. On/Off 2 yrs. Only take when asthma really bad-(it is a "tempting drug" works wonders for asthma. Side effects horrendous. Took because Pro-Air which is all I can get now - does not seem to work real well replaced Albuterol because of the harm to the ozone layer - RIGHT. I am Coming off 5 mg. 1/2 pill 48 hrs. now sneezing again, but can't sleep but exhausted. Like crashing from an illegal drug. Take your little ones off this drug immed. if you see any symptoms in their personality. They may not be able to communicate what they are feeling. Merk should be sued. SINGULAIR IS A DANGEROUS DRUG. and expensive too. F 51 2 years

 1  constant allergies Extreme rage, inability to focus, profoundly upsetting nightmares/dreams Took this once. Just once. I have been on allergy meds for years and never experienced this kind of reaction, or any reaction really. My adult brother was very scared for/of me, and we just talked on the phone. Lucky for me I took it on a day off or who knows what would have happened. This took a couple of days to get out of my system. Will never take it again. F 51 1 days

 5  Formerly unmanaged asthma So far, none. That is HIGHLY unusual for me! I have spent the better part of my adult life being tired and having asthma symptoms (long undiagnosed). My asthma was not diagnosed until I was in my 30's, and no doctor ever really managed it correctly, or at all. I kept on believing that my breathing wasn't too bad. After becoming progressively tired over the past year+, I told my primary care doctor that we needed to find out what was wrong with me, that I couldn't go on feeling the way that I was feeling. A full cardiac work-up revealed a perfectly functioning heart. The pulmonologist's report wasn't as rosy. He believes that my years of untreated asthma have caused some permanent damage, and that there may also be COPD involved. He put me on Advair and Singulair. I decided on taking 5 mg. of Singulair rather than the prescribed 10 mg, since I'm less than 5' tall, and under 100 lbs. I'm frequently given doses of medication that are too high. Well, I can't say for sure which drug is doing what, but I do know that I have not F 50 10 days

 3  severe allergies This medication has really helped me. HOWEVER, I was @ the allergists 2 days ago and waiting around for my shots when I picked up a Singular pamphlet and started reading the back. I had to read it over and over again in disbelief. Suddenly it hit me. I had been wondering why I have been so angry, irritable,no motivation, etc. OMG. Then I mentioned it to my dr. saying I feel like breaking dishes every day. She said, you have to stop right away!!! There should be more of a warning on this med. These symptoms arent even mentioned in the primary listings. There are so many people who are given this drug and like sooo many patients they dont ask questions and they DON'T understand when they begin feeling badly. I wonder if there are any studies out there of indiv who were on this and ended theirs lives or came close to it. F 50 8 months

 3  Chronic rhinitis and nasal polyps Anxiety, depression, mood changes, irritability, drowsiness, sleep disturbances, vivid and strange dreams This drug works better than any other nonsteroidal drug for my nasal symptoms, and it helps to diminish stuffiness and restore my sense of smell. However, the side effects are profound, and Singulair makes me feel hyper-sensitive, emotional, anxious, depressed, and gives me vivid and strange dreams bordering on nightmares. I am glad to had found this website, because now I know that others experience the same side effects. It is too bad, since the drug works well for sinus problems; I just don't know if it is worth it, with all of the severe side effects it causes. F 50 14 days

 3  Asthma, Allergies, MCS Over the last several years I had been experiencing lower back and hip pain, which I attributed to age. I have also over the last two years tried to reduce the medication I am on during the winter (I live in the north east) while allergens are low. I have stopped taking singulair over the winter two years in a row and stopped and started recently to test my theory, While I am not taking sinuglair I have no lower back or hip pain it is only when I return to taking it does my lower back and hip pain return. I also have noticed I experience muscle aches and spasms in my lower legs in the morning while I am taking singulair. Unfortunately I will have to stop taking it for these reasons. It did seem to help my allergies and asthma in the past but the side effects of the pain doesn't warrant my continuing it. No Additional comments F 50 16 years

 2  Allergies, astma Headaches, Numbing of the fingers and arms. Heart rate up, with palpatations. Anxiety, general weirdness feeling. WARNING!!!! FOR THOSE WHO THINK THIS WORKS GREAT! This drug almost cured me from being sick with respitory problems my whole life that were literally life threatening. HOWEVER- long term I started getting numbing, tingling in my hands and it has always made me anxious. I am an adult. I finally figured out the cure wasnt this, it was all the food allergies i had!!! Check your blood for food allergies! A lot of the wheat soy and the rest is being manipulated and is GMO. Our bodies react to this. I got off this drug almost completely and the numbing has subsided.

 2  Asthma Emotional outbursts, flooding of thoughts, joint pain, racing heart, spaced out, insecurity and negative self talk, suicidal thoughts, hopelessness. Singulair did a great job on the asthma it was the other crazy side effects that took me over the edge. Used to be on 10 MG and am down to 2.5 and hope to be off of it soon. I spent thousands of dollars on therapy, counter balanced these side effects by taking more drugs: Adderall (ADD Drug) for the spaced out and inability to focus, VIOXX for the joint pain, bursitis and aches (until it was taken of the market), COUNTLESS natural remedies running me thousands of dollars. Currently I am detoxing and drinking Kangen Water. The Kangen water has been most beneficial for my breathing and detoxing whatever was giving me the asthma in the first place. F 50 11 years

 2  Asthma - Sinusitis - Allergies Nightmares, anger, anxiety, agitation, heart racing and jumping and odd feeling. This is the third time I've tried to take it; yes, there's *some* benefit for asthma, none for chornic sinusitis or allergies. But, I still need Advair every day and Albuterol. Doesn't do as much for asthma as it once did and it ALWAYS had distressing mental and heart side effects. My doc said those are not in the book but admitted other patients come in and say the same thing. I'm going off. F 50 12 months

 1  asthma/allergies constipation and abdominal pain After maybe a week or so taking it, I became suddenly and severly constipated, and was doubled over with abdominal pain, then vomited. Two days later the abdominal pain came back just as bad, but without the vomiting. It came in waves, plus still severe constipation. It was so bad I ended up in the ER. I had no idea why I was so constipated and in such pain. It didn't occur to me for a few days that it could be related to Singulair. When it did, I stopped taking it to see if there was a link, and sure enough, I returned to normal. Has anyone else had these symptoms? F 50 7 days

 1  Allergies I have been unusually depressed - suicide thoughts - lack of mental acuity. Also, primary reason I took this was to get rid of a cough but I cough every time I breath cool air from air conditioning. Also experiencing breathlessness at times. I went online to see if my depression could be associated with any drugs I am taking. I also take blood pressure medicine (losartan) but have not had any problems with that in the past year.

 1  1st for Asthma, then for allergies Depression, moodiness, loss of libido, loss of interest in hobbies, life etc. After hearing that Singulair was linked to people committing suicide, I decided to stop taking it. Without doctor supervision (I would not suggest doing that), I went off it cold turkey after being on it for 7 to 8 years (I 'quit' around the end of March). I used to feel 'frozen' inside -- not temperature-wise, but emotionally. It was scary to get all this feeling back in just a few days. I've been happy for the first time in many, many years. Unaccountably happy. I had thought the emotional problems were related to circumstances and aging, which might have had a contribution. But I am on other medication that seem to be controlling the asthma and allergies and see no reason to go back taking Singulair. The change for the better in my emotional state has been dramatic and I want to stay this way. F 50 7 years
