Montelukast "Have been on Singulair since it came on the market in Aust years ago. I call it my magic pill with no obvious side effects despite having many other allergies. I didn't find it helped my hay fever though, so I take half an antihistamine as well in summer when humid and winter when smoke from fires around. I went from high dose cortisone puffers and using Ventolin most of the day, still being breathless and wheezing all the time, to breathing free within 4 days of starting and off all puffers within the week. Due to cost, about a year in was running out, so cut down to half tablet which still left me free of the asthma. Then tried a quarter and found this still worked, so have continued on this since then. (to be continued as not enough space)"

"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 "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 "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."

Montelukast "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 "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 "I was prescribed this to help with asthma control. I noticed in a few days that my rhinitis had significantly improved, as well as the constant sensation of mucus at the back of my throat. Asthma is generally better controlled. I do not think Singulair has helped with my exercise-induced bronchospasm, as I still take Ventolin prior to each cardio session/run."

Montelukast "I'm on Singulair for asthma (I've grown out of it mostly) and for allergy/rhinitis maintenance. It works wonders! I also lived in China for two years, and it was critical for me managing the monthly colds I would get there. This stuff really keeps congestion and allergies at bay, love it!"

Montelukast "I have been taking Singulair for 10 years. Singulair has virtually made my asthma almost non-existent! I take it every night and rarely have to use my inhaler. Since I also have seasonal allergies, there is usually a short period of time when I find I need a puff from my inhaler, but it's not often. Any and all medications can cause side effects, and everyone will have different experiences, but I feel that the risk was worth it! The only real issue I believe may be associated with Singulair is excessive dryness in my nose that causes sores every now and then. I feel comfortable staying on Singulair because being able to breathe easily far outweighs the one side effect I have."

Montelukast "My 4-year-old son was on this for a year. It worked wonders for his asthma but made him a very violent and aggressive child. We didn't notice the changes in his behavior until he had been on it for over 6 months. His fits of rage became more and more frequent. We finally decided that we would take him off to see if the Singulair was the cause. We noticed changes in him the first day he was off of it. He is back to being my sweet and loving child with no rage and no violence. It is a great drug for those that don't have this side effect."

Montelukast "I have had Asthma all my life. This medication CHANGED my life. I have always used albuterol (inhaler and nebulizer) for fast-acting relief, along with steroid preventative inhalers. Two years ago when I was diagnosed yet again with pneumonia, my new doctor prescribed Singulair. I am an active person who likes to run etc. Until Singulair, I had never in my lifetime run without having to use my albuterol both before and after. Not only that, this year I made it through flu season without developing pneumonia. Until I used Singulair, I had never known what it felt like to be 'normal'. To run and exist without having to stop because I was wheezing and couldn't breathe."

Montelukast "I have been on Singulair for less than 1 week. I have noticed that with the slightest bump I bruise easily. My mouth is dry, but my throat is not closing in. I have been sleeping better and have been more active. Still take allergy medicine occasionally, Advair and blue puffer. Wowzers."

Montelukast "Singulair has been a blessing for my asthma. However, when I was switched to the generic in October, all of my asthma symptoms came back: wheezing, shortness of breath, and the use of an inhaler (which I only used prior to exercise) several times a day. My doctor has written me a prescription for brand Singulair. The pharmacy gave me the three pills they had in stock and ordered the rest to come in tomorrow. I did the same thing a few weeks ago with another pharmacy, and their distributor no longer carries the brand. Hopefully, this will not happen again tomorrow and I can go back on the brand Singulair. Since the problem with the generic, I have been on Prednisone, Symbicort, and two nasal sprays to try and get my asthma under control."

Montelukast "I had horrible side effects from Singulair. I started suffering severe anxiety attacks, which my boyfriend (who is an EMT) linked back to Singulair. My allergy doctor wasn't even sure it was the Singulair until I talked to my pharmacist. Heed caution that the rare side effects can happen and that they are scary."

Montelukast "I have mild asthma that occasionally worsens to be more moderate. I'm another person who has mood effects from taking Singulair, and in addition, it's affecting my ability to enjoy certain flavors. It feels like an antihistamine, sort of, causing my mouth to feel dry, and I feel thirsty a lot. I'd live with that, but I am experiencing this weird agitation that's quite uncomfortable. I'm very aware of it, and I'm an adult, not a kid, so I probably won't bite anybody's head off. However, I think it might not be worth it to me, and I think I'll stop it for a few days to compare how I feel then with what I'm feeling now."

Montelukast "The inhaler from the allergist didn't help my breathing problems. I always felt the fresh air I breathed in only got halfway down and then hit a filter of some sort. I had wheezing and whistling every day at the end of my exhale. The inhaler didn't help. I was out of breath from the slightest activity. I got a prescription from my family practice doctor for this. This has eliminated my wheezing and out-of-breath feeling. I'm allergic to just about everything year-round. It did not eliminate my need for allergy medication, but it has made my breathing perfect. I wouldn't ever want to do without this medication."

Montelukast "I have been on Singulair since it was first on the market. This medication has given me a life that is free of fear from episodes of asthma attacks. Before this medication, I was using a steroid inhaler and short-acting and long-acting inhalers. Not to mention the nasal spray and the allergy medication. Five medications versus the one of Singulair, plus a fast-acting inhaler for exercise or shortness of breath."

Montelukast "I have used this drug for over 15 years. I have asthma triggered by inhalants, and the original version has totally controlled my symptoms. I used the generic when it came out because of cost. I started having mild asthma symptoms within a few days. When my local Target switched to another generic, I developed hypersensitivity pneumonitis, which was diagnosed after over $20,000 in lab work and a bronchoscopy. Back on original Singulair, and no problem again. It really controls my asthma and allergic reactions."

"Think long and hard before you take this stuff! I ended up in the psych hospital on suicide watch! I’ve never had mental health problems in all of my 64 years. I am/was a successful, healthy, and articulate attorney/professor/writer/dancer. The bizarre nightmares/paranoia/hallucinations became so severe they thought I had schizophrenia. I lost my job and almost lost my husband. My doctor doesn’t believe this was caused by the Singulair, but all of the symptoms slowly went away in the 6 months after I quit taking it. Sadly, I’m not sure I’ll ever be the same person. My cognitive ability has greatly suffered."

Montelukast "I've been stepping up and up since I was diagnosed with asthma. First, it was just Ventolin, then we added Clenil Modulite, then Seretide 50/25 at Christmas, up to Seretide 125/25 a few weeks later, adding in Avamys nasal spray for hay fever and Acrivastine for hay fever and Type 1 latex allergy, then finally adding on Montelukast. Sadly, unlike some of the other people on here, I haven't been able to get down to just Montelukast. However, I'd say it's a miracle pill! I play ice hockey, and overnight I went from tight chest and coughing and wheezing after hockey (I have CVA, so wheezing is weird) to being totally fine. I still struggle if I max out, so I have to change out regularly, but I play forward, so that's easy enough. It's just great!!!"

Montelukast "Singulair has been a godsend to help control my daily asthma symptoms due to allergenic/mold triggers. I haven't noticed it make a difference with exercise or smoke triggers, but it definitely helps reduce frequency/severity of asthma symptoms in general. If I take a few days to pick up my prescription, I can absolutely feel a difference in my lung health. I've been waiting the past few days to get the entire prescription renewed with my doctor, and I had a nighttime attack last night for the first time since I started taking the medicine (it's been six days since I last took it). I have not experienced any mood changes even though I already had diagnosed anxiety when I started the medication or any other adverse side effects."

Montelukast "I am in disbelief as to how much help this has helped me after MONTHS of trying different inhalers and medications for asthma and struggling to breathe so badly, having to be on steroids so often just to breathe. My Dr. gave me Singulair and within the first 24 hours, I went from having to use my nebulizer every 3/4 hours to using it once. I've been on it for about 3 weeks now and I am no longer needing my inhaler or nebulizer!!! I absolutely can't believe it. It has changed my life for the better."

"WARNING!!! I was prescribed this medication 9 days ago after a serious asthma attack. I’ve had mild asthma (mostly exercise-induced) for about 20 years but haven’t been on preventative meds since I was in high school. Since beginning this medication last week, I have experienced major mood and psychological changes - this medication is awful. I have felt completely foggy, out of it, dissociated from reality, disinterested in anything, unable to concentrate, shaky, fast heartbeat, my teeth hurt and feel like they are covered in a weird film. Seriously, I felt like I was in danger of my own actions. I am never taking Singulair again, and I would caution every person who is prescribed to really pay attention to how you feel because this is NOT normal. I read that the medication has a pretty quick half-life, so it will hopefully be out of my system in the next 30 hours."

Montelukast "I have been on corticosteroids for about 10 years due to asthma and allergies, many times bronchitis and pneumonia. Asthma very bad this year and have increased use of Symbicort up to 8 inhalations per day, usually 4, no better, so doctor prescribed Singulair on Monday, and 4 days later feeling somewhat clearer but producing more sputum, itchy and trouble resting, very hyper. I will try to stay on it for another 7 days to see if it settles as per the pharmacist."
