For Asthma "OMG!! I've been taking Singulair for one week. I haven't received my Advair from the mail order pharmacy... But, Singulair is a miracle. I had shortness of breath (SOB) and tight chest - it felt like I was having angina. Really, after the first dose, I noticed I coughed less. Today I walked all the way from the back parking lot to my floor without stopping or SOB. Didn't even have to use my inhaler. Amazing!"

For Allergic Rhinitis "I have horrible hay fever. Regular antihistamines do not work for me. I still suffer a lot if I take them. Terrible itchy eyes, runny nose, terrible asthma at night which kept me up, and a whole lot of sneezing and an achy body. My doctor prescribed me Singulair along with Patanol and Nasonex. Singulair has changed my life forever. My symptoms have been reduced by as much as 95%. I have no asthma, sneeze occasionally, and my itchy eye episodes occur sporadically but stop within minutes. I don't usually even carry eye drops with me anymore, which before would have been insane of me not to do. I'll give Singulair a 10/10 due to the fact that I've had amazing results and it's the only medication I need to make it through allergy season!"

For Asthma, Maintenance "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."

For Asthma, Maintenance "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!!!"

For Allergic Rhinitis "I am 29. Singulair alleviated my seasonal allergies in the beginning for a period of 2 weeks maybe. After that, I had the opposite reaction, was having a hard time breathing, and my nose and throat were dry all the time. I stayed on it thinking it was something else, then I decided to quit it because after a regular run, it triggered tachycardia. This was something I never had before, I am a healthy guy, used to push myself hard during workouts. Once I stopped, there were no issues with a dry nose or anything else. Guess I'm one of the minority that have adverse reactions to it."

For Allergic Rhinitis "This drug did nothing for my stuffy nose, cold, cough, and wheezing, but the side effects are horrible. After less than a week of taking it, I could not sleep, was unable to focus, had a panic attack at the grocery store with sweating and dizziness, felt like I was going to faint, was very tired and achy. I did not connect it to the drug at first, but then I went to take it, and it dawned on me that maybe I should check out the side effects. These are all side effects of the medication. I had lost my mother about a month ago, and I kept thinking I was just not coping well, but once I stopped taking the medication, I was able to sleep and the sweating and dizziness went away. My aches are much less as well."

For Asthma, Maintenance "I've been taking Singulair for three weeks now after going off Advair, which is no longer covered by my insurance. I now have to use a rescue inhaler several times a day and am constantly coughing, feel out of breath, and tired. Maybe three weeks isn't long enough of a trial period. I'm hoping my breathing gets better in the next week, or I'm calling the doctor to try another medication."

For Asthma "I have been on the real Singulair for over 20 years. It has saved my life. I have had allergies since I was 6 that led to asthma. I almost died 8 times before finding Singulair. I also have skin allergies. Since I have not been able to get my Singulair in the last month, I have lost 1/2 my hair and now wheeze constantly. Please bring it back, if only for asthmatics."

For Bronchospasm Prophylaxis "I have really bad asthma, and nothing seemed to help. I recently started taking Singulair, and my asthma has improved unbelievably. No more wheezing and severe headaches. I feel like a new person."
