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  Asthma My son / age 4 has become very aggressive, defiant, and displays bizzare behaviors, like cutting his hair,pushing and punching people, and not listening. My daughter / age 7 has been wetting the bed, sleep walking, and night terrors. All of these symptoms started about 1 week after they started using Singular consistently. I reported my concerns to the FDA for more research about the real effects of the singular. F 29 20 days

 1  Allergies Severe anxiety, heart palpitations, constant panic attacks, unusual behavior and thoughts, very upset and easily aggitated, unusual dreams and hallucinations, GI disturbances I cannot understand how several doctors insist that this is such a wonderful drug. It works therapeutically for asthma but the side effects are horrendous. Drugs work differently on individuals but the ratio of this drug benefiting any individual is outweighed by it's adverse effects. I began taking Singulair in October 2010 and my entire life has spiraled downward. The panic attacks and constant anxiety would never cease. I have been to several doctors and have spent so much money on trying to find out what was wrong with me. It got to the point where I was almost incapable of functioning. I was having 3 to 4 panic attacks weekly and ended up in the hospital on a couple of occasions. I have my bachelor's degree in Psychology and I am currently in nursing school so I was struggling horribly with this turmoil. For those who like to comment on this page and say that maybe we are just crazy and that singulair has worked for them, well that is wonderful in their case. But clearly any intelligent person can see that this many people CANNOT make up all of these side effects. This drug has hurt my relationship and has affected my 11 year old daughter. I started counseling because I am highly against the use of anti-anxiety/antidepressants and of course every doctor I visited said, you are just having anxiety and stress because of school, let me write you a Rx. for an antidepressant. That is not normal but unfortunately that is what is done in todays world. F 29 4 months

 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 After just one day on the medication I noticed an extreme difference in my thoughts and behavior to the point that I stop taking it immediently. I felt like I was trapped in a room knowing I would be tortured at any moment. It's a horrible drug and I can only pray that the FDA will remove it from the market at once. F 29 1 days

 1  allergies Dizziness, light-headedness, anxiety, depression, irritability, headaches, twitchy, tingling sensation. My Dr specifically said that it had zero side effects, so I took this for about 2.5 weeks before I realized that I felt miserable and put it together that it might be the Singulair making me feel this way. I stopped taking it 5 days ago and still have had bouts of dizziness. I would much rather have allergies than feel this weird. How long will it take for these side effects to wear off? F 29 2.5 weeks

 1  Asthma First time taking these, straight away my teeth hurt. I had mood swings and my sex drive died almost over night. They do help asthma there is no denying that but the trade off is awful. Hair loss, depression anxiety all of which I have never really suffered from. Being very in tune with my hormones I could sense I was not myself almost instantly. Symptoms did appear to subside. I missed a week or so and my asthma began to worsen again. Once I started again my mind went out the window and rage almost entirely consumed me, not to mention coming out in a severe rash in the space of a couple of days. Would not recommend would rather suffer asthma. M 29 4 months

 1  Seasonal allergies Anxiety, psoriasis, rage, low testosterone, suicidal thoughts. DO NOT take Singulair! I was prescribed this for years to help with seasonal allergies, chronic sinusitis, or allergic rhinitis, whatever you want to call it. As the years went on I started being controlled more and more by my emotions. I developed a skin rash all over my body that looked like psoriasis. My testosterone also tanked to clinically low levels. Three weeks after quitting Singulair all of this started to disappear. I have now been off singulair for 5 years and consider it a life-changing decision for the better. Please do not take this, especially if you are considering it for a child. The mental damage is not worth it! M 29 6 years

 1  asthma first night taking this medicine. woke within an hour of falling asleep shaking, petrified thinking I was about to die with severe heart palpitations. feeling sick with stiffness over body. Now have a fear of falling back to sleep. I searched the net within an hour of this happening as was very affraid of what was happening. I would rather have to use my Salbutomol more than take this medicine again. I can't understand why my Doctor would give me this when I also suffer with anxiety and depression for this medicine to make me feel even worse. Feeling a little more reassured now I'v read it it isn't just affecting me this way.

 1  asthma/allergies I noticed that after about 2 months I started having really terrible nightmares, became very restless at night and unable to lay still in bed. I took 10mg last night before bed like usual and had the most horrific experience ever. I had an overwhelming feeling of fear, felt like someone was in the room with me when I was alone, and stared seeing things move in the shadows. I could not sleep, I was too scared to close my eyes. I stopped taking the pill cold turkey tonight, and I am hoping all of these side effects go away. I will post an update after a week. F 29 3 months

 5  Asthma Interrupted sleep & insomnia at the beginning, but I managed by taking the dose at 7-8 PM instead of right before going to bed as prescribed. Possibly heightened senses (smell & hearing) but this could also be due to a healthier diet. Interestingly I feel a lot more patient with people, more positive, and less anxious than before starting Singulair (not sure if it's the diet or Singulair but I won't complain!). It works so well for asthma, I don't need to constantly worry about it anymore. I still need to use my inhaler before exercising but otherwise I rarely need to use it, I only need it sometimes for minor symptoms after dusting & cleaning the house. I'm very satisfied with it for now, although I'm a bit scared to develop side effects long term. F 28 7 weeks

 5  to improve asthma conditions i havent really experienced any side effects with singulair. After reading people's comments i really got nervous that i would experience these terrible mood swings, or depression but i did not at all. Singulair is my oxygen. It has helped me cut down tremendosly on my short term inhaler. I take advair and singulair together everyday and they have done wonders for my asthma. The advair alone was not working so my doctor added me on singulair about 4 months ago and it has been the best decision. F 28 4 months

 5  Asthma None I love this medication. I have been fortunate not to experience any side effects and have had lots of benefits. My asthma is never better than when I am on Singulair and it knocks out my allergies which are a main cause of my asthma. My mother had temporary depression when she started this medication but I never experienced that. F 28 3 years

 5  Allergies No side effects. Greatly reduces my seasonal allergies to the point where I rarely need to take an anti-histamine (though I still do if I don't get enough sleep which makes my allergies that much worse). M 28 2.5 years

 5  Seasonal allergies and asthama Made me tired so I took it at night. Drs. gave it to me for what they thought might be allergy induced asthma -- it turned out to be GERD. But the singlair did help with the seasonal alleriges that I had. F 28 4 weeks

 4  Asthma Works well for my asthma. Recently switched to the generic. Was fine with Teva generic and now experiencing headaches with the Glenmark generic. Don't know what could be different but I get cluster headaches within an hour of the dosage. Want regular Singulair back. F 28 7 years

 3  Asthma and allergies My doctor started me on Singular because I would wake up every night about 3 am gasping for air. He prescribed this more for my asthma then my allergies. Within days, I was sleeping through the night and my allergy symptoms disappeared. It was like I never had asthma. A few months later, I started having panic attacks in ramdom places where I was not under stress. My dreams and nightmares became more vivid and pretty distressing. I started seeing things move out of the corner of my eye when there was nothing there. My sex drive disappeared entirely. Then, I started hearing voices in my head tell me to kill myself. (At this point in my life, I had a good job, was going back to school partime, and had the most wonderful boyfriend. There was no reason for me to be unhappy) I had enough sense to realize that this behavior was unlike me and then found this site and saw that I was not crazy. I went off the pill and all of the side effects went away in 2 weeks. I took it once after having an asthma attack and had a panic attack within an hour. That was all the validation I needed. I've been off of it half a year and am back to normal except for my sex drive. I hope it comes back. Did anyone else have problems with their libido? The doctor cannot find anything wrong with me but I suspect Singulair. This is ruining my relationship. Help! F 28 1 years

 2  Chronic rhinitis Balding, myopia, acne, aggression, and hard to focus. I tried going off Singulair two years ago, but after taking it for so long my body seemed to be addicted. I had a large wax buildup in my right ear that got infected. Other than that I loved being off the stuff. I was insanely productive at work. The ear pain finally got to me though. I went on a quick prednisone burst and got back on Singulair. The shysters at Merck decided to raise the price again, and now that it exceeds what my insurance will pay so I am going to go off it again. I am armed with Loratadine(Claritin), pseudophedrine, guaifenesin(Mucinex), and Nasonex so hopefully I will make it this time. Wish me luck. M 28 8 years
