Fluticasone / vilanterol
"Ive had asthma since I was 5 and now I'm 42. I've always only used rescue inhalers for most of it and since I've taken this 1x a day I rarely ever use my inhaler and I'm never short of breath. It's apparent that this is not for everyone as I've read some reviews. I have been taking it for 3 months and have never had any side effects. I'm a fan.....actually was given a free 12 month prescription for this and that alone saved me $50-100 a month I'm guessing!"
