I have been on Advair for approx 4 years. I was unaware of the side effects. My voice became hoarse at times and I had the thrush in the mouth. I am annually checked by my eye Dr. and was surprised to fine catarracts . this is a side effect. I developed a curvature of the lower spine due to increased osteoporosis. This is also a side effect. I was discovered last year to have some infiltrates on the lungs. I just had a bronchoscopy and it shows I have eosinophil pneumonia... I read up on Advair and these are all side effects. I have been off Advair for about ten days now and I am SOb > I think this is just withdrawal symptons. I have been on 250mgm.2xpday and 500mgm 2xpd. I am sorry I ever went on it.
