For Asthma "I have been on Singulair for a couple of weeks after years of being on a steroid inhaler for exercise-induced asthma. It has been working great, but I'm gaining weight like crazy. So unfortunate, but I will go back to my inhaler."

Montelukast for Allergic Rhinitis "This medication really helped my allergies! It was so severe this year. I was constantly uncomfortable. Felt like I couldn’t breathe. I was starting to think I had come down with the flu or another illness. This medication helped my allergies so much, the best medication I’ve ever taken for allergies!"

Montelukast for Asthma "Thank God for Singulair. I got my life back. My asthma was so bad, I was afraid to go anywhere without my nebulizer. Now my asthma is almost non-existent. I have no side effects and feel great. I just wish I would have had this medicine many years earlier, it would have saved many trips to the emergency room and much suffering and panic."

For Asthma "I have noticed a lot of bloating and hot flashes on montelukast. I do feel like it helps with the cough I get from allergies and shortness of breath. On the other hand, I have been gaining unexplained weight and extremely tired!"

Montelukast for Asthma "Started Singulair approximately 1 week ago. I will say it's an asthma miracle, but the side effects are unreal. I had extreme irritability (out of character for me), severe fatigue when normally active, mood changes, depression, anxiety. I wish doctors would really explain this to new users. Thanks to all of you who reviewed this medicine and gave me insight on what was going on, that's the reason for my post too."

Montelukast for Allergic Rhinitis "Finally, finally, finally! I was originally given this for COPD and asthma so you might be wondering why I am writing this under allergic rhinitis. 24 hours after the first dose and ever since, my nose and sinuses are clear for the first time in literally my entire adolescent and adult life. I can sleep, breathe, and it has greatly helped asthma! Not a single side effect to be found."

For Asthma, Maintenance "I've had asthma all my life, and after 14 years, montelukast was introduced to aid my other medication. For a year and a half, my asthma was controlled, and then my dosage was doubled because I turned 16. After the increased dosage, my mental health worsened, and after dealing with terrible anxiety and depression for 18 months, I realized that it fitted with the time period that I'd been taking this and was worsened with increased dosage. It had all been side effects. The extra montelukast was a tipping point in my mental health, and I became suicidal. I stopped using this immediately, and my parents got me help. After 6 months, I had recovered. I share this in the hope that it prevents the same thing from happening."

Montelukast for Asthma "I was on Singulair for a couple of years, and I have depression with tremors/muscle spasms. Since stopping the meds, the pain in my back next to my lungs has returned but depression is getting better. Tremors are still happening after 2 weeks of not being on this."

For Asthma "I’ve had mild asthma since childhood. Despite this, I smoked for 25+ years and quit on Aug 11th, 2010. I’m 53, and I’ve tried nearly every nebulizer treatment, daily maintenance, and long-term bronchodilator. Singulair/Montelukast was prescribed to me for no reason other than one day my pulmonologist said, ‘it couldn’t hurt’. Boy, was he wrong! By the time I realized it was likely causing a bad side effect, I was popping Ativan like candy. I had an overwhelming sense of dread! Like fear, sadness, anxiety, and terror all rolled up into one. I write this review because I want everyone to realize the possibility. I have been off of the drug for nearly a month now, and I’m back to normal! In my opinion, if you want something to truly control your asthma, just use Symbicort! It works better than anything I’ve tried in my lifetime."

Montelukast for Allergic Rhinitis "This drug is not for everyone. I took it for just three days and got very depressed, even to the point of having really dark thoughts, had a constant headache, an upset stomach, deep soreness in my teeth, mood swings, and irritability. However, it did help my allergies. Be very conscious of how you feel when you try this drug."

Montelukast for Allergic Rhinitis "Honestly this medicine has helped my allergies drastically but my anxiety is off the wall. I’ve been on it for about 2 weeks... the first few days I was okay but around day 3 I stopped being able to sleep and started waking up with really bad anxiety and muscle/joint pains. I wish they could make this medicine without the side effects :)"

For Asthma "I’ve been on Singulair for 5 years now. Prescribed to treat mild asthma and allergic rhinitis (post-nasal drip). Paired with a daily dose of Zyrtec, I don’t find it helps my chronic post-nasal drip as much as I expected it to (it does some), but it definitely cleared up the mild wheezing I’d suffer from every night. As for side effects, I don’t believe I have ever suffered from any. I also have mental health issues like general anxiety disorder and OCD (both diagnosed prior to taking this), and neither felt exacerbated."

Montelukast for Allergic Rhinitis "Started taking Singulair with Zyrtec 3 weeks ago for a severe allergy I developed to my 3 pet rabbits. No side effects to speak of (I did have a headache one day, but I don't think it's related) and today I held one of my bunnies for the first time in 6 months without allergy symptoms. Now I don't have to get rid of some beloved family members!"

Montelukast for Asthma, Maintenance "I cannot take Singulair. I have asthma. My symptoms are I can't get a full breath. I get very short of breath regardless of if I am sitting or walking. I have a constant runny nose, so I thought I would try Singulair. I was on it a week, and it made my struggling to breathe worse. I stopped taking it, and I feel much better. I think Singulair made the mucus viscous and hard, so I couldn't get rid of it. Hence, my breathing got worse. I get very, very fatigued. I'm sad as I was hoping this would work for me."

Montelukast for Allergic Rhinitis "I am a parent of two children. Both children took Singulair for allergies. Both children had issues while taking Singulair and experienced withdrawal effects once I stopped the medication. My daughter developed tics, tremors, anger, rage, OCD, anxiety, mood swings, and agitation, to name a few side effects. My son developed frequent urination, muscle issues, joint pain, and sadness. Both my children developed a hypersensitivity to all artificial sweeteners, dyes, and all emulsifiers/preservatives as the inactive ingredients are made up of most of these items. Their hypersensitivity to artificial sweeteners, dyes, and emulsifiers/preservatives still continues even though they stopped the medicine."

Montelukast for Allergic Rhinitis "Started to get post-nasal drip horribly over four months ago. Tried every OTC drug known for allergies, removed bedroom carpet, bought high-end humidifier and air purifier, used a neti pot, and drank four liters of water a day. Nothing helped, and I would wake up every hour and a half coughing from mucus build-up. This medication stopped my symptoms within 2 days. It's very expensive but worth every penny."

Montelukast for Allergic Rhinitis "Amazing results! I have suffered with extreme allergies for many years. I had tried nasal sprays, over-the-counter allergy meds, & even took the allergy shot-nothing worked until I started taking Singulair. Now I can actually smell flowers in bloom! I use it in combination with Zyrtec."

Montelukast for Asthma, Maintenance "This medicine worked wonders for my 3-year-old's allergies, however, I am in the process of taking him off of it. He has always been a very well-behaved child, soft-spoken, and very smart. Since he started taking the medication (from the first day), he has been completely unable to sit still, has been chewing on things (something he outgrew a year and a half ago), and has been unable to follow simple directions. He has also been much more aggressive. When I asked him about it, he said (word for word), 'It makes me feel wiggly. And when the wiggles start, I can't stop them, and the house spins, and I fall down.' I urge parents to keep an eye on their children for behavioral changes always, especially with this medication."

For COPD "I've had COPD for over 10 years, and I was taking 1 montelukast 10 mg in the evenings. After reading about the half-life of the drug, it seemed to me to be most effective when I was asleep, so walking is my exercise-induced asthma. I started taking my 1 10 mg pill in the mornings, and it has turned my activity around. I feel much, MUCH better breathing in the daytime. I can tell my bronchial tubes are open. I have had no nighttime issues either."

Montelukast for Asthma "Since taking Singulair I have tooth pain, tingling in my face, and a bad metallic taste in my mouth. Plus my anxiety level went up, feel really tired, and very agitated. Stopped taking it last night. Hope these side effects go away soon. This metallic taste is driving me crazy! This is the 2nd time I've tried it. Same side effects and more."

Montelukast for Asthma, Maintenance "I took this medication a few years back. Although I read the side effects, I never imagined that I would have a bad reaction to the medication. This medication worked great in controlling my asthma. However, I became very depressed, suffered from anxiety, and just not me. It didn't happen immediately, but people started noticing a difference. I started noticing a difference. I never had a history of any of that stuff. After I came off the medication, I was back to being me. For me, the side effects weren't worth it."

Montelukast for Asthma "I started taking generic Singulair on 7/26/17. By 8/02/17, I started having vivid dreams only at bedtime and every night until today when I called my doctor and got the medication changed. For just under a week, every single night, I couldn't tell if I was awake or dreaming. The first night it happened, I was cuddled up with my husband, sleeping on his chest, and I woke myself up snoring. When I apologized to my husband for snoring so loud, he said I wasn't snoring. I fell asleep again within ten minutes and thought I was still awake, I swore I saw a spider on the sheets by my face on my husband. I jumped up, yelling 'spider!', woke myself up, and freaked out my husband because there was no spider, I had dreamt the whole thing. It only got worse."

Montelukast for Asthma, Maintenance "My 6-year-old son has been in and out of the hospital since he was a baby with breathing problems. He was officially diagnosed with asthma when he was 2. He had been flown to a children's hospital, and that's where he was diagnosed. He was put on a Flovent inhaler. This cut down on our ER trips, but not totally. We figured out that his asthma attacks were triggered by wind storms, allergy-related things, etc. They then put him on Singulair. I call it the Magic Pill!!!! We have not been to the ER in 2 years!! No side effects that we can tell."

Montelukast for Allergic Rhinitis "As soon as ragweed season starts in the Mid-Atlantic (August 15th), I literally go downhill in my health. I constantly have post-nasal drip, but during ragweed season, the post-nasal drip turns to a sinus infection. I have been on class 5 antibiotics for the past 3 seasons. I was thinking that the only thing left for me was to move to Florida or the Virgin Islands (no weeds I'm allergic to). I decided to try Singulair. Within hours, my symptoms completely stopped. I'm literally in awe. I thought it would take days to notice improvement, but it was virtually instantaneous. If you have serious allergic rhinitis that does not respond to antihistamines, please give it a try. It could change your life."
