"I never had any asthma until I moved into a house with mold (green, black mold). After one year got my first asthma attack in the morning. After three years had more attacks in the morning while I am sleeping. Got a bad cough, woke up and couldn't breath anymore. A couple of weeks later I got a bad bronchitis. Couldn't breath anymore normal, walking steps was almost impossible. I was thinking it goes away. After 2 weeks it was so bad that I went to a doctor. She said OMGoodness how can you breath. Your lungs are full of mucus. She gave me an injection so I can breath normally again. Also gave me Seretide and Montelukast. I recover after I was moving to a new house without mold. After one year in the new house my symptoms almost gone. But I lost my smell and taste, stuffy nose all the time, crazy dreams, fatigue, gain weight almost 30 pounds, Stomach pain, dizziness and numb arms and hands when I ride my Ninja, Thanks to god I found this website. I will immediately stop now Montelukast."

Singulair (montelukast) "Asthma and allergies. I have both. I've tried every steroid and bronchial dilator inhaler and had awful side effects. I can only take tablet steroids short term for the asthma. Allergy-wise, I've tried Flonase, Claritin, Zyrtec, Allegra, all of it, and still have bad drainage and cough. So, my doctor prescribed Singulair. I vaguely remember being on it as a teenager, and I remembered I was taken off it. He said, "try it again now as an adult." Well, I had awful anxiety and panic attacks starting from the first dose. By a few days into it, I had been constantly battling the anxiety, and one night had a full hallucination. I thought, for sure, I heard someone in my house. I was up looking everywhere, freaking out. I'm a single parent; I can't be going crazy to feel better! So, within 1 week, I had to stop it. I did notice the post-nasal drip was a bit better, and my asthma cough at night was still there, but not as severe as it was. No idea what we will try next. It was scary and frustrating."

"At 40 years old, I have had increasing allergies mostly with nasal congestion but also shortness of breathe. A couple years ago I was prescribed 10 mg of montelukast for a respiratory infection. Once I stopped taking the medication I realized the shortness of breathe returned so my doctor prescribed it continuously. I have a gained 40 lbs in the past two years with most around my upper back and stomach. I have been off the medication for one week and have noticed a remarkable reduction in puffiness/bloating in many areas of my body. I discontinued the use because their is a greater risk of weight gain then any benefit I had."

"I have been on Singular for six years. I have asthma and allergies that get worse every year. I had episodes where my throat would start closing and I could not breathe. They are nearly gone since I started singular at night. I did gain weight, and I do have night terrors, but I have not experienced any other symptoms."

Singulair (montelukast) "It worked very well for asthma symptoms. Greatly reduced lung inflammation. It takes quite a few weeks to reach max effectiveness. But gave me joint aches, muscle aches and all over malaise. This is listed as an uncommon side effect so it may not affect most."

Singulair (montelukast) "This really did help with my allergies and asthma symptoms I sometimes experienced. I took this for 2 years and never on a daily basis, but as needed (when my allergies would act up). It took me a while to figure this out, but I have now determined that when taking this medicine, I am very lethargic the next day, depressed feeling, and extremely agitated. For a while I had just concluded I was a moody person, but after taking one, seeing how I felt, and then going off of it, I put two and two together. Literally the next day without the pill, I feel back to my old self. So though it did help for allergies, for me the pros don't outweigh the cons."

"I have been taking montelukast for three months, I persisted with the vivid nightmares, irritability, anxiety and depression because it was so effective for my asthma. Family, friends and work colleagues noticed my mood change and my inability to be happy. The weight gain was another unwanted side effect. The prolonged and worsening side effects have forced me to stop taking it."

"This genuinely changed my life. 32 and have chronic asthma/allergies/eczema, since birth. I could barely move most days, it was disabling. I was on the top dose of steroids and they weren’t controlling it. I’d be in hospital with attacks and just generally living a horrid life not being able to breath. I can’t tell you how Amazing it is to be able to exercise, go on walks, keep up with people, not wake up numerous times every night needing inhalers and forever worrying, trying to stave off going the doctors/hospital. I just wish I’d been put on them sooner and I might not have wasted my 20s! Still use inhalers but much less, my asthma is still there, but is ‘controlled’ along with proactive behaviour (dust/chemical avoidance etc) something I never thought I’d be able to to do. Also on fexofenidine once a day for anyone needing help to figure out what might help them. No side effects for me - lost weight but that’s because I can now move."

"I started this medication when I was diagnosed with pneumonia. I thought my gas, bloating, fatigue and weakness were from the antibiotics but even after finishing them the bloating etc got worse so I am guessing it is the Singulair. I don’t think I really need it so I will stop taking and hopefully feel better. After reading all of the information on anxiety and depression ( which I have had for 30 years) I am shocked my Dr. put me on this."

"I took Montelukast for 9 days before bedtime. I was having frequent common cold, so my doctor prescribed me Montelukast as an alternative to Levocetirizine. My Asthma is not so serious as I only use the Revolizer and not the inhaler. I'd advise everyone to not use this med as it has some serious side effects. After taking the first few tablets, I started feeling anxious and I experienced breathing problems. I visited the doctor and he said that I shouldn't have any breathing problems as my lungs were fine. Then I checked for the side effects of Montelukast and found out it has a lot, so I consulted with my doctor and he removed Montelukast from the prescription. It's been 5 days since I dropped that drug and I still feel anxious and difficulty in breathing at times. Reading others reviews have helped and now I'm just going to wait till this anxiety goes away. I just hope that it goes away, this anxious feeling is getting on my nerves."

"I experienced horrific side effects from this drug. After about 4 days of taking it, I developed anxiety and depression, body aches and extreme feeling of tiredness. I stopped taking it right away, but I had flu-like symptoms for the next 5 days or so, where I could not even get out of bed. I'm now on day 9 off the drug, and am slowly getting back to myself but still feeling quite tired, sleepy and anxious."

"I have taken this medicine for about 2 years. I do not know if it has helped me because my asthma is not bad all the time. I do know that I used to have bad panic attacks when I was young (62 now) and they went away. I have had several surgeries in the past two years so I thought my anxiety was due to my heath issues. Today again I had a anxiety attack and suicidal random thoughts for no reason! I finally read all the side effects for my meds. The only one that has these psychosis word warnings is this one!!!!!!!!!! I am mad,,, I will go off it tomorrow.. I don't need to take something confusing me and making me psychotic Beware of this medicine!!!!!!!!!!!!!!!!!!!"

Singulair (montelukast) "I started taking 5mg when I was younger. And I’ve continued with 10mg for the entirety of my adult life. It’s a must-have for me to function. Just opens my lungs without all the prednisone—one of the best medications on the planet, in my opinion."

"I started taking this medicine montelukast May 2019 on Labor Day weekend for asthma. To make long story short it is now October, and I officially got diagnosed with severe allergy induced asthma. I used advair pump daily and take this Montelukast along with strong allergy meds and then more allergy meds. I haven’t been to ER ever since I was in this montelukast. My concern is serious gain weight. I am a soldier and I’m pretty active I weight lift and CrossFit...besides not being able to run when I was having asthma attacks I still do serious weight lifting. I’ve never weighed in past 150lb in my entire adulthood. Now I've lost my abs and now have a 31 inch waistline from 28inch. I was also getting daily muscle spasm in my hands and feet and they are painful (I thought I was dehydrated) Today I quit taking this montelukast...I love that it helped my sudden asthma but I quit smoking"

"My daughter is 7 yrs and she had been taken Singular for 4 yrs It worked great. But for the last 3 months my daughter started have extreme anxiety issue over little things to the point where she wasn't herself. Saying things like nobody loves me, I am a bad kid, you should just get rid of me. she was having tantrums, outbursts of disruptive behavior. major mood swings. Crying hysterically at night. I researched and researched in what was causing this behavior and came across side effects of her meds and it was worth a try even though it could alter her health but her mental health I was way more concerned about. By the 5th day of her being off on the meds she was back to her normal loving and positive self.I will never give it to her again"

"Started taking this medication about two years ago and it has changed my life. Before the montelukast I would use my rescue inhaler(proair) about five times a day even more sometimes. I had that annoying cough that just wouldn't go away, super whizzy, tightness in chest, could barely walk like two flights of stairs without being winded and starting to wheeze it was horrible. I finally started taking the montelukast seriously saved me. I take it everyday. I can finally breathe no annoying cough, no waking up trying to catch my breath, I can finally go for a run and not die and even laugh all I want without reAching for my rescue inhaler! I feel so much better!"

"This drug gave me back my life. I have cough variant asthma and flare ups would last for months. I would have violent coughing several times an hour. This takes the "itch" or "tickle" away so I no longer feel like I need to cough. It also helps with the feeling I need to clear my throat. A godsend."

"my daughter is 4 years old and developed these behaviors Over the course of 18 months. we were not informed about any of these side effects and no monitoring was done either.

I wouldn't recommend this drug at all without proper monitoring"

"There is a gap between the known side effects of this drug and doctor education. We placed my child on it unaware that it causes nightmares and violent behavior in children. He did experience both, to the point where he was almost removed from a regular classroom in 3rd grade. I had a nurse friend educate me and we did take him off. The nightmares and violent outbursts have completely gone. It doesn't happen to all users but it did for my child. We switched and are managing with saline spray and Flonase with success. It almost ruined my child's life at the time. I also filed a complaint to the FDA on our experience on this as well."

"When my asthma drug was discontinued, I started taking Montelukast with horrible side effects! For a week or so, the asthma improved and I was very happy, but then I slowly developed some type of breathing problem unrelated to Asthma. My breathing was very heavy, and I had a chest discomfort and could barely walk to the bathroom. Feeling of extreme anxiety and felt like I was suffocating. I tried to do controlled breathing for hyperventilation in case this was the problem. I don't know if the drug caused me to hyperventilate or if it cause such anxiety that I hyperventilated on my own or if it was some other kind of breathing difficulty. I stopped the drug and it took about 3 weeks for symptoms to leave permanently."

"I was diagnosed with allergies/asthma at 3 I’m now 44. I started smoking at 17 and since never real had attacks unless I caught a cold. I got sick last fall with what we thought was bronchitis. I quit smoking I was so bad. For the next 6 months I was at the ER 6 times and on prednisone 5 times. I was told to give it time for my lungs to heal. Last month my brilliant new doctor put me on this medication. I can’t say enough about how this has helped me. I can actually feel it working. This may sound crazy but I will start to feel my chest start to tighten then it stops. Where as before when I would feel it tighten up I would start wheezing and coughing. I have not had any issues with side effects but I’m already on Prozac. At this time, as out of control my asthma was, I would live with nightmares if I had to. For myself this medication is as important to me as air!!"

Singulair (montelukast) "My son has had asthma from the beginning, he was placed on Singulair at 18 months. It did seem to help, but he has now developed side effects and we have taken him off of it. He becomes very agitated, and aggressive. He is normally a very calm and sweet child. It took a while to put two and two together. We took him off, and his sweet nature came back. Truthfully, it scared me how much this medicine affected his mood. It works great for asthma, but we won't use it anymore."

"My daughter has taken this for about 8 years. She's always seemed to have extreme emotional reactions to the smallest things. I asked her doctor multiple times if it might be the montelukast she takes causing this. Dr. said "no, reported side effects just happen when the child starts taking it. Must just be her personality". I know what is normal and her reactions were extreme. Everything came to a head this past winter when she started having obsessions about eternity. We took her off the montelukast. About 2 weeks later she had a psychotic break. She was crying all day saying she didn't want to exist. It has taken 2 months to get her back to semi-normal. This drug is not good for children!!! Her experience is not unusual!"
