| 4 | asthma | I've been on/off Singulair for about 5 years now. I feel best when I'm on it but the nightmares were overwhelming and truly frightening after a while. BUT my doctor had me start taking the Singulair in the morning instead of nightime and that worked! The nightmares went away and it's great. I do still get them sometimes when I'm very stressed out but they're minor, not like the big ones I used to get when I took it at night. Try mornings! It works! | F | 45 | 5 years | 2/27/2006 | 4 | Asthma | Slight fatigue. | Singulair has been very effective in controlling my asthma. Because it tends to make me drowsy I take it at bedtime. | M | 45 | 5 years | 6/11/2002 | 3 | asthma | Prescribed Singulair last year. Miracle drug for first three weeks, then terrible terrible constant palpitations. | Had tests to ensure nothing wrong with heart. Taken off Singulair. Palpitations went away after a few days! Prescribed again earlier this month - no palpitations as yet, but terrible stomach upsets and nightmares. Fluid Retention too, which is nice. | F | 45 | 15 days | 8/29/2006 | 3 | asthma | Prescribed Singulair last year. Miracle drug for first three weeks, then terrible terrible constant palpitations. | Had tests to ensure nothing wrong with heart. Taken off Singulair. Palpitations went away after a few days! Prescribed again earlier this month - no palpitations as yet, but terrible stomach upsets and nightmares. Fluid Retention too, which is nice. | F | 45 | 15 days | 8/29/2006 | 3 | asthma | At first, Singular worked great, turned off my Fall asthma like a switch. The past 2 years, it seems like it is not working as well as it used to. I developed eye twitches that lasted for many weeks, conjuntival cysts on my eye after starting the medicine (Last fall and the fall before that). I cannot sleep well when on Singulair. This year, the sleep problems are huge, i don't remember them being this bad before. After 3 days on this, I decided to quit Singulair. I can't handle the lack of sleep and a 3rd year of eye twitching. | I thought the symptoms were unique to me and not reported by others using Singulair but I am seeing others with same symptoms. I am a little dismayed that when I told the Dr the side affects and she could see my eye twitching herself, didn't say anything. She even sent me to an eye specialist to see about the headaches, conjunctival cysts, and eye twitching. I was dismissed by the specialist as wasting his time. It was nothing important that I had. While Singulair worked great the first few years I took it (I only take it Sept-Dec), the side effects have become too much for me and after 4 days of being on it this year, I am quitting. | F | 45 | 4 years 10 1X day | 8/26/2010 | 3 | Dog/cat allergies | I am extremely allergic to dogs/cats but I live with 3 dogs and am involved in animal welfare. I have tried other OTC and prescription medications with not much relief. I researched Singulair and read the reviews. I asked my doctor to write me a prescription and mentioned all of the reviews where I had read about the side effects of nightmares and suicidal thoughts. He laughed it off and asked me if I believed everything I read on the internet (I will not be seeing him again). I told him no, but that there were so many people saying the same things. I began taking Singulair and could finally breathe again and not spend my days blowing my nose and sneezing. Almost immediately I started having crazy dreams and they felt like they went on all night so I was exhausted in the morning. After several months I wasn't dreaming as much but now my whole body seems sore all of the time. I'm 45 and feel like an old woman when I get up after I've been sitting a while. I don't take any other medications | F | 45 | 8 months 1X day | 1/26/2016 | 2 | Asthma | Body numbness, aches & shooting pain in left leg. Vaginal pain/numbness/sore, sometimes feels like I may have UTI. | My asthma seems better, but the side effects are unpleasant. | F | 45 | 8 days 10mg 1X day | 10/15/2020 | 2 | asthma and allergies | very crippling migraine, extreme lethargy | but did not need my inhaler once the whole week (usually 12-16 times a day). But will probably stop taking them due to migraines and fatigue. | M | 45 | 7 days | 2/18/2006 | 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 | 8/23/2007 | 1 | severe allergies | For myself, congestion to the point my sinuses would not drain, therefore giving me dizziness and vertigo, just aweful! For my daughter, anxiety and depression with problems in school. We are both OFF this stuff! | I am curious, has anyone else had dizziness or vertigo from Singulair? Would like to hear from ya. | F | 45 | 3 months | 2/3/2008 | 1 | seasonal allergy | Anxiety | I tried it a few times and each time I experienced uncomfortable levels of anxiety. It did work to solve the allergy symptoms but I couldn't live with this side effect. | M | 45 | 5 times | 4/17/2009 | 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 | 4/5/2009 | 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 | 3/24/2009 | 1 | Rhinitis | Severe dizziness. Panic attacks. | Got no relief whatsoever for nasal congestion. Still have postnasal drip and horrible cough all night long. Am very dizzy and nervous. Feel horrible and can't wait for it to wear off. Won't take it again. | F | 45 | 5 days | 5/4/2006 | 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 10mg 1X day | 2/5/2010 | 1 | Itchy eyelids, skin allergies | Within 1 hour of taking 1 pill I became extremely nauseous. It lasted about 2 hours. I was pleased to find this website, but greatly concerned about all the effects others are reporting. I will NOT be taking this drug again. | F | 45 | 1 days 1xD | 9/5/2013 | 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! | M | 45 | 3 months 1X day | 11/23/2011 | 1 | Allergy | I became immediately moody, angry, depressed, tired, had restless sleep, nightmares, and one day I found myself listing out all the possible ways I could commit suicide. I am known as a person which is always happy and smiling, and this is not my personality. I tossed the drug and will never take it again. | F | 45 | 7 days 1X day | 3/17/2011 | 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 10mg 1X day | 3/19/2020 | 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 1X day | 6/1/2017 |
