Montelukast
"My asthma's been getting worse every year, and spring allergy season is the worst. I got on Singulair three weeks ago and it's completely changed my life. I haven't needed my Albuterol at all in the last two weeks. I can breathe free and easy. For the first time in years, I've been able to walk to the store without wheezing. I wish I'd gotten on this a long time ago, but until recently I couldn't afford the prescription cost. I'll really be happy when a generic is available."
