Last Sunday, I had to go to the emergency room because I couldn't breathe. At times, it felt like my body didn't WANT to take a breath. Scary doesn't even begin to cover what I felt. Until that day, I had NEVER been hopsitalized for my asthma. It turned out to be a severe asthma attack. I am convinced that the only thing that saved me was that I am a classical singer and am used to controlling my breath. Had I panicked, I am not sure I would be here to write this. However, it wasn't until last night that I realized this was all from the Advair. Yesterday, I had a really good day. I only used my rescue inhaler a couple of times (since I still have a few residual breathing issues from the severe attack a week ago.) As I went to bed, I took my Advair, as usual, and within 30 minutes I was having trouble breathing again. Nothing as severe as before, but enough that I found this website and others and all of the comments about the side effects,as well as, the FDA warning about this "product". I immediately threw my diskus away. Thank you all for your posts!
