| 1 | Asthma | Out of character violent tantrums and behavior, difficulty sleeping, strange statements, talk of nightmares, spacing out..... | My 3 year old was prescribed and started this two weeks ago. Gradually it was like she underwent a personality change. My previously loving, caring, funny little girl became quick to anger and lash out and became very needy. I have taken her off it since finding these reviews yesterday and can already see a difference in her behaviour. I was at the end of my reason with trying to cope with her prolongoned outbursts and tantrums, and was actually a little bit afraid that she would hurt her younger sibling. She slept better last night than she has for two weeks, and I feel like my little girl has come back to me again today. She's back to her old self, and any bad behaviour (not that there's been much) was easy to circumvent! I can't believe they give this to anyone, never mind kids. | F | 38 | 14 days | 10/27/2008 | 1 | Asthma, allergies | Depression, mood and behavioral changes | I started taking Singulair in September 2007. It worked great for keeping my asthma and allergies under control. However, the emotional side effects I experienced were horrible. Within a month of taking it I noticed I started to become depressed and lethargic. In December anxiety started. I thought all of these emotional occurances were due to stress. In January I became worse and started lashing out at family and friends. February and March were the worst. I became suicidal and as early as last week contemplated killing myself because I couldn't take it any more. Thank god my friend heard the news reports about Singulair and called me immediately. I have been off the drug for 3 days and I am starting to feel like myself. I urge people not to take this drug. | M | 38 | 7 months | 4/4/2008 | 1 | Asthma and allergies | After less than one week on it I started having extreme low back pain (I'm already dealing with lumbar back problems and it made them much worse). Nausea. A bad sinus infection for which I've had to take two different antibiotics. Halucinating -- on a trip to look at Fall foliage, I was sitting in the passenger seat and panicked several times because I believed that we were going to crash into guardrails and other cars. Trouble spelling words which was really weird since I've always been an excellent speller. But the worst was the sudden mood swings and extreme feelings of depression and hopelessness about my back problems, almost suicidal even. Lashing out with crazy anger at my husband for no reason. Only minimally helped my asthma and allergies, which really aren't that bad anyways. | This stuff is bad news. A nurse practitioner gave me a month's worth of samples to take, never mentioned possible side effects. I've never experienced drug side effects like this before in my life. Had I not stumbled across this site while researching Singulair and two other drugs I started taking recently for my back, I would probably not have made the connection. Frightening. I stopped taking it after about 3 and a half weeks and the side effect symptoms completely disappeared in 3 days. I'll never take this stuff again. | F | 38 | 25 days | 10/1/2006 | 1 | Allergies | I took montkelust for several days and I cried, had anxiety, lost my temper and contemplated suicide. I am a happy, stable person and was baffled at the irrationality of my thoughts. Then I forgot to take it for a few days. I felt better, took it again and the symptoms returned. I am so glad i finally read the warning label and put two and two together. What an awful experience. | F | 38 | 5 days | 9/15/2015 | 1 | Allergies | extreme tiredness, even after 12 hours since taking the drug, numbness emotionally, fuzzy thinking, beginnings of panic, feel unmotivated and unable to function. | Took the generic - Montelukast. Do not recommend. | F | 38 | 1 days 10mg 1X day | 5/19/2016 | 5 | asthma | none! | Been asthmatic for approx 37 years! have taken all manner of inhalers, inhaled steriods as well as steriods in tablet form With various amounts of sucess. I take antibiotics approx 7 to 8 times a year due to chest infections, normally triggered by some kind of allergic reaction A new locum at my surgery reccomended this drug and within three days I felt better then I have done for approx 10 years. I enjoy going out now for long brisk walks and hill walking I am out of pain (I suffered pain in the back chest and ribs when feeling run down) I wish I had found this years ago If hyperactivity is one of the side effects then Im looking forward to it!. from looking at the other comments maybe it is better for adults?? | F | 39 | 2 weeks | 10/27/2007 | 4 | Chronic cough due to allergy | First week headaches, flu like symptoms, weight gain about 1lb per week. lethargy and occasional joint pain. | I love that I finally get a good night sleep because it is helping for the cough,but recently losing 40lbs I am very depressed gaining 6 back!! I will probably ask for something else or suffer. I thought I was crazy gaining weight, I was counting calories and exercising as usuall and started gaining. Atleast now I know it wasn't me. They really should put this side effect on the label. | F | 39 | 30 days | 9/20/2006 | 3 | Asthma | Terrible weight gain (15 lbs.), horrendous migraines, decreased libido and nightmares. | I finally realized the connection of the weight gain and migrains when I forgot to fill the prescription about two weeks ago. Since. . . I have lost a little of the weight (which was IMPOSSIBLE to lose while on), no headaches, but I did have one asthma attack due to allergies. | F | 39 | 4 years | 7/24/2006 | 3 | Allergies | Anxiety, nightmares, pnuemonia, cough, bleeding | This drug relieved my nasal rhinitis. Unfortuntately I started having nightmares and after awhile started having anxiety. The anxiety was exhausting. I also got pnuemonia for 1 month, which was the first time. Not sure if Singulair caused it. Other thing is when I would wash my face, sometimes my pores would bleed for no apparent reason. I also started to have a cough. I stopped taking the med and these things cleared up. Not sure if that is a coincidence or not. | M | 39 | 6 months | 10/24/2008 | 3 | Allergies | Would get upset over little things that normally wouldn't bother me. Had severe nightmares!!! | It helped a great deal at night for me to sleep better without trouble breathing. I worry about the children that are on this and can't verbalize the nightmares they may be having. Mine were horrible. | F | 39 | 1 months | 12/21/2004 | 3 | asthma | WEIGHT GAIN!!! The weight gain was evident and uncontrollable. I gained 17 lbs in 7 weeks with eating less and exercising more. There were times when there was extreme urgency to move my bowels. Intense Diarrhea. The diarrhea wasn't a constant when on the med but when I had it the intensity was worse then a stomach virus and URGENT. Again the most obvious side effect was weight gain. I was shocked when it wasn't listed as a side effect. If it wasn't for being in touch with my body and being fit this weight gain could of went on for a while. I'm thankful for the people on the internet that supported and voiced this very same side effect. | M | 39 | 2 months 10 MG 1X day | 3/8/2016 | 3 | Asthma | Since taking singulair,I itch all over and its uncontrollable. I now take texa to stop this. My memory has become really bad and I am even on anti depressants now. If I take my tabs an hour later than usual, I experience these serious painful chest pains, feels like I can rip my chest open. It is extremely painful and you feel like you're going to die! Why? What am i allergic to thats in these meds? I use the generic kulair and it does the same. I know it causes depression as I have bee been on anti deps since being on singulair after a few months. | It really works to keep the chestyness away and reproduction of phlegm but the side effects does affect my way of life and not sure if the meds clash by chance. | F | 39 | 7 years 10 | 8/19/2015 | 3 | Allergic asthma/ Copd | Irregular heart beat, neck pain and shoulder pain. Chest tightness. Numbness on left side of face. And tingles up and down both legs. | Breathing is better but I don't know if I can continue with numbness and jumpy heart rate. | F | 39 | 36 days 10mg 1X day | 10/1/2020 | 2 | Asthma and allergies | Ear aches, tingling, numbness, back of calves hurting , light headed, headaches, tiredness, anxiety | Had to be put on antibiotics for ear infection - no I would not recommend this to anybody | F | 39 | 0 weeks 1X day | 7/11/2022 | 2 | 3 1/2 yr old for allergies/asthma | My son who was already strong-willed has been on Singulair for approximately three months. He's always been high-energy and difficult to discipline but he started having these negative thoughts and speech "I hate myself" I hate you/my sister" and calling people idiots and hitting more/biting etc. - and until I happened upon this website did not even think it had anything to do with his medication! He also has had hallucinations/bad dreams frequently at night and told my mother that he heard a bee in his ear - which is what caused me to suspect his medication. After reading all of these posts I took him off of it two days ago. So far I have not seen a change and he is a little asthmatic so I am calling his allergist about all this tomorrow. | I am OUTRAGED that I never was told about these side effects and to hear that it was reported in the news - I am guessing I must've been under a ROCK that day? I would have never put my son on this medication if I knew. Sadly, it was really helping with his allergies and asthma and now we'll have to try something else possibly. We took him off Zyrtec b/c he had issues on that as well and it dried him out too much and made him too drowsy. | F | 39 | 3 months | 2/15/2009 | 2 | asthma related cough | bed wetting | My 9yo son has had significant issues with bed wetting in the past but we finally had it under control. He just started singulair 5 days ago and has wet every single night - sometimes twice! This just can't be worth it. He already has frustration and behavioral issues so there's no way I want to risk adding to his problems. He's off. | F | 39 | 5 days | 11/9/2009 | 2 | Asthma | The crazy maker! I started taking this medication a month ago and became depressed and extremely anxious with tightness in my chest. Sweaty palms. Near tears a lot of the time. Irritable. Hyper-sensitive. Moody. Emotional. Panick symptoms for no reason. | My asthma symptoms did dissappear but it doesn't matter because the side effects are worse. It does work for asthma - my breathing became a lot better, no wheezing or asthma symptoms. The anxiety symptoms are too much though so I'm going to quit it. | M | 39 | 1 months | 11/11/2006 | 1 | Asthma & Chronic Sinusitis | The first 7 days Singulair seemed to work just fine without any side effects, but then on Day 8 I started to feel nauseous and that continued at least 5 more times to the point of deep breathing to control any vomiting. Unfortunately, as of today that didn't work, and I actually vomited. I have also had an increase in coughing where it was almost non-existent before. I am on Effexor for depression, and it works great; however, I'm also feeling more depressed and really lethargic, which isn't like me. I missed one dose yesterday, and last night I couldn't sleep at all, even after taking my prescribed Ambien. I finally fell asleep for about two hours. During that time I was freezing and then I had the sweats while having nightmares and waking up with extreme joint pain. I called my doctor and said I'm taking myself off. I don't like feeling this way, and I'm going to see if all these symptoms stop within the next couple of days. I have a feeling they will. | Although I know others on this product, I would not recommend it due to the many side effects. I am not one to suffer from side effects, but this product definitely threw me for a loop! | F | 39 | 14 days | 11/22/2006 | 1 | allergies | Took 1st dose (on empty stomach) and within 5-10 minutes had strong tingling in hands and arms, then top of legs. That receded, though hands still feel a bit tingly an hour later. Shortly after that, had uncontrollable body tremors (like shivering, but wasn't cold) on and off for about an hour. | Waiting for the clinic to open so I can call the doc and follow up. Will NOT be taking this again, far too scary for any benefit I might get. Makes the fatigue, lightheadedness and dizziness of my past allergy meds look like a picnic. | F | 39 | 1 days | 4/19/2006 | 1 | child taking it for asthma | After being on singulair for about 5 days my child woke up one night in a panic and hallucinating that spiders were in the bed. She is 31/2 yrs old and never has displayed behavior like this before. It was very frightening to see her this way. I literally had to chase her around the house because she kept runnning from "these large spider". I have not given her singulair since. | If any one else had this particular problem with the hallucination in a child taking singulair, how long before the hallucinations stopped? | F | 39 | 5 days | 8/12/2009 |
