asthma
"I started taking Singulair about 10 years ago when it was fairly new. It changed my life, I am not aware of side effects, but I NEVER WHEEZE! It is the best drug over and I would recommend if you use your albuterol inhaler more than twice a week, take this medicine! I was using my rescue inhaler almost daily, now I NEVER use them, I keep one on hand, but I throw it out annually and get a replacement so I always have a fresh one, just in case."
