I have been using Advair off and on for the last couple years. Each time i have gone on it i have gained weight and i have been unable to lose it. I had no idea there was any correlation, untill someone mentioned to me how they had gained a lot of weight by using prednisone, which is also a steroid used to treat asthma. It all makes sense to me know. Does anybody know of a asthma preventitive treatment medication that does not cause wieght gain.
