"I have about 24 side effects listed. I feel like I have been beaten all over my body from taking this. It's also making me weak, nauseous, and dizzy. I do not advise on taking this for folks with fibromyalgia, myasthenia gravis, or arthritis."

Montelukast "I wish I had reported this to the FDA when it happened. I don't know how helpful my account of the side effects from years ago would be now. However, I would like to share this somewhere, as what I experienced is not verified as a side effect but possibly suspected-I don't want anyone to go through what I went through and not suspect this medication. After taking one dose of Singulair in the evening, the next day, I experienced suicidal thoughts, anxiety, and a feeling as if I were being separated from my body (if that makes sense). I have no history of such problems, never took Singulair again, and never experienced what I described again (as I said before, it has now been years since I took Singulair)."

Montelukast "I have tried it several times in the past but have the same results. It does not control the steady flow of post-nasal drip, causing me to feel nauseated. I have better results taking 4-hour generic Benadryl."

Montelukast "I took Singulair last summer and was so excited that it worked. But I started displaying side effects like anxiety, panic attacks, and a feeling of wanting to cause harm to myself. I stopped taking it for several weeks, then tried it again, same side effects. I was quite upset because it actually helped the sinus problem."

"My mom was on this medication. I was not aware she was, I just knew she was on something for her allergies. All the side effects listed that others are reporting on here are exactly the same ones she had. I wish I would have done research and known more about what had been prescribed. My mother committed suicide a month and a half ago, and we couldn't figure out why. My brother passed away tragically 11 years ago, one of the hardest times of our lives, and my parents and I made it through that. We were at a point where we didn't dwell on his death as much. Things were looking up, and our family was doing good. I gave my parents 2 grandkids. No problems in my parents' marriage. No problems with me. I had actually just sent a Mother's Day present that she never opened. I really hope people read reviews on this medicine, and I'm glad others have shared their side effects to help others. I'm glad that my dad and I might have an answer to our many questions. Please do not take this medication. It should be taken off the market."

"I have allergies generally. My life has been hell for the last year. In three days, since I started this, I felt better than I have in ages. My only problem with it is that I don't fall asleep before three without a little help, and I'm always hot. I can handle those two things though, because I feel decent."

"I have been having chronic sinus infections due to allergies for the last year and a half. I finally went to an ENT who prescribed this medicine along with my current regimen (Allegra D, Flonase, Neti Pot). I have been on this medicine for about a week now, and I am unusually irritable and easily aggravated. I can tell that it's getting worse, as today I started developing anxiety along with it. I am not going to take it tonight and call the doctor in the morning. I saw on the label about mood issues and depression, but this is more like taking a stress amplifier. If I had complete relief from the allergies, I would consider continuing, but I haven't noticed an improvement, I still have extensive postnasal. Glad to see I'm not the only one."

"Went to the doctor because this time every year, I have problems with pollen and asthma exacerbation. He gave me generic Singulair 20 mg once a day. The first dose I felt like I could breathe better. Then the next day I took the second dose. That night I woke up with a panic attack, my heart rate was over 130. This medicine is a dangerous medicine. I thought I was going to have a heart attack. Please reconsider before taking this medicine."

"The worst thing I have ever been on. The doctor prescribed me this to make the inflammation go down in my nose since steroid nasal spray didn’t help. It made all of my symptoms so much worse. I then developed nausea, migraines, and tiredness throughout the day. I felt so weak my legs went numb at one point."

"Although this medication seemed to help my allergy symptoms, my mental health took a terrible turn. For the last few months, I've been having crazy outbursts, going 'from 0 to 100' very quickly on an emotional scale. I became super aggressive, could not stop crying, and would lay in the bathtub having suicidal thoughts. I know now that it was this medication, and my doctor told me to STOP taking it. These side effects could ruin someone's life, especially if the people around you don't understand why your behavior has changed. I've also been suffering from severe fatigue-fatigue that is much worse than my normal allergy fatigue. I'd recommend allergy shots instead, even though they are super inconvenient for many people!"

"I've had sinus surgery to clear the stuffiness (worked wonders), but of course, I will still have allergies - year-round. If it's not sinus pressure, it's headache, runny nose, mucus drainage, watery eyes. I take Zyrtec, Flonase spray, Ipratropium spray, and Azelastine spray in the PM. There is nothing more that can be done but move to another state. I wouldn't be able to function without meds, but I still suffer symptoms now and again. The last 2 weeks were bad. Had my primary Dr. appointment last week and told of my extra suffering the last 2 weeks (with my meds). He decided to add Singulair at night, saying there are no interactions with what I currently take. Called my ENT (who did my sinus surgery) and he said no interactions, so try it. BOY, WHAT A MISTAKE! I took 1 pill last night and I could hear/feel my heartbeat loudly, which was slightly elevated. Could NOT sleep well at all. This stuff is going in the garbage! BEWARE? Have someone near you to keep an eye out for any reactions!"

"I've been on this pill for about a year now. I was doing great in the spring and summer, but as soon as the mold and ragweed hit, all of my horrible symptoms came back. Antihistamines do nothing for me. I have itchy, dry eyes, the top of my mouth itches, my ears itch, my face and back are itchy, too. I'm going to continue to take that pill, though. I have never experienced depression, anxiety, or agitation."

Montelukast "Singulair causes symptoms in children that look like ADHD or ADD. It causes irritability, aggression, impulsivity, and hyperactivity in children. Before you treat your child for ADHD, try switching to an allergy or asthma medicine that isn't this or a corticosteroid."

"I was prescribed this Rx for chronic sinusitis one year ago by my PC physician. Due to the powerful effect of this drug on me, I could only take 1/4 of a 10 mg tablet each day. The drug worked well for a few months, but suddenly the results tapered off. Coincidentally, at this time I started experiencing moderate depression, dark thoughts, paranoia, nightmares, and lack of energy and motivation. My husband has clinical depression and anxiety, and I became concerned when I started experiencing similar traits. I have never been depressed, but now I have developed it from taking just 2.5 mg per day. Better product guidance on packaging for patients and physicians may be helpful."

"I am a person with anxiety, and I’ve had minimal side effects of this drug. It has helped tremendously with postnasal drip and constant congestion/cough from vasomotor rhinitis. I’ve taken it for almost 10 years on and off depending on the season. I wanted to write a review aside from all the negative reviews. I was very nervous about this drug, and for a long time only took a half pill & currently take about 75% of one, and it really helps me. It can make me a bit speedy feeling at times & sweating/redness but not so much that I would want to stop taking it as it really helps! I wanted to give a different perspective of a review on this drug as it has really helped me."

Montelukast "Well, it did the job pretty efficiently, so it gets an extra star for that. However, I was left with a rash and swelling that started closing off my airways the next day. It took 5 days to realize that it was a side effect of the drug. I stopped taking it and popped one Benadryl, and the next day my throat was half its previous size and my face burned much less. Still recovering. It was so expensive and ended up doing this to me."

"Had severe allergies causing laryngitis. Lost my voice for 13 days. Went to urgent care and was told to take Zyrtec and Flonase. The day after visiting urgent care, I was experiencing severe eye pain and could not open my right eye. I then went to the emergency department. The ER doctor told me it was a severe case of allergies and prescribed ketorolac for my eyes. Three days later, I saw my PCP, and she prescribed Singulair and told me to take it in the evening. Within two hours, my voice came back. I am so impressed with this medication. No side effects noticed."

"Works great, but the disturbingly vivid dreams are making me feel exhausted. I stopped taking it for a few days, and the dreams stopped. But my breathing worsened. Wish there was something else I could take."

"My doctor gave me montelukast for allergies and I have been on it for about a year. I recently stopped taking it because I've noticed I'm getting leg cramps at night in bed, my entire body just hurts. My anxiety is through the roof, and my mood has been bad - everything and everyone irritates me. It makes me breathless when walking and I cough a lot more. I didn't take one last night, and I feel more relaxed today."

Montelukast "I was prescribed this for headaches and eye irritation for allergies. Been taking it for a month. No improvement or change in symptoms. The doctor's office said it takes a few days to help symptoms; the pharmacist said it can take 4-6 weeks to build up in your system. The generic is cheap, but after a month, no change. Don't know if it's the med not working or misdiagnosis."

"My 8-year-old suffers from year-round allergic rhinitis. He started taking montelukast, and it helped him sleep through the night without snoring, nor did he have breathing problems or a runny nose the next morning. But he started getting depressed and complained about 'feeling sad for no reason.' I've stopped the meds, let's see how it goes."

"Horrible side effects; my quality of life was zero. I felt spacey and couldn't think. Couldn't rise from my bed. I had interest in nothing. I felt feverish and dizzy. Worst of all was the terrible pain all over my body, but especially in my legs and hips. A dangerous drug. But it helped my asthma. What's a person to do?"

"The boxed warning side effects are real. I have been on montelukast for many years. In the last 5 years, I have been diagnosed with depression, mood imbalance, and behavioral changes. All very unexpected by those who know me. I stopped taking montelukast and am seeking alternative treatment for allergic rhinitis. I have noticed a difference in my mood and a decrease in depression. For anyone taking montelukast, make your fam/friends/coworkers aware you are on this medication and to be mindful of any changes they notice in you."

"My doctor prescribed me with Montelukast (Singulair) and within a month, I went back to him and thanked him. It has changed my life for the better. I rarely need my puffer or preventer and hardly get all wheezy and allergy. It's honestly a game-changer. He did warn me of the side effects but the only side effect I had was the vivid dreams. They were full-on scary."

"After two weeks of using montelukast, I started having really bad nightmares, waking up early, feeling anxious. During the day, I would feel really tired, with pain in my ankles. Some days later, my memory got worse, I started forgetting words, was really slow, it just felt as if my mind was blank and I didn't know how to do basic stuff. I had very strange thoughts, felt really dark and in a bad place. I started feeling really depressed because of this, I was afraid that I'll lose control of myself, became a totally different person. It was then I read this page and started crying when seeing that there were so many that had the same issues. I stopped taking montelukast immediately, now it's been 72 hours off montelukast and I'm feeling almost back to normal. The first day after the medicine was rough, but slowly it got better. Please take this and other users' experiences into account before starting the drug, it should be forbidden to take it."
