I have been usung advair for a good number of years, but the oral thrush was a very big problem. I switched to symbicort, and found that the oral thrush was even worse. With the symbicort, I actually had the lesions on my tongue that bled a lot. I take Plavix, which makes this even worse. I went back to advair, and was trying to find something to use that sort of had tolerable side effects but still worked on my asthma.
