Regarding thrush and Advair.. Since starting Advair I had a severe bout with Thrush and since and though I do rinse with warm water faithfully after each use of the inhaler, I've had an on going battle trying to control the yeast in my mouth which especially seemed to be worse when I'd awaken in the morning. I started taking the vitamin supplement Biotin (5000) mgs each day to treat a non related symptom that I was experiencing though strange low and behold I no longer have issues with thrush or yeast build up in my mouth. On further investigation I found out that Biotin can actually control the over growth of yeast which is what Thrush is. It really works!
