I have been taking advair for years on and off. I was upped my dose to 250/50 and for the last year have struggled with feeling terrible. I didn't really think it was the advair for a long time. Thought it was something else and the doctors didn't find anything wrong, they were looking at hepatitis, thyroid, adrenal etc. But I feel sickly all the time, like I have the flu... those body aches all in my back and chest and I feel tired all of the time. My lungs sometimes hurt. I get dizzy spells as well and am struggling through my day. Has anyone experienced this on Advair? I have just decided to go off and use my inhaler... which I am trying not to use unless I am really wheezing. Trying to get all the steroid out of my body to see if that makes a difference. How long will it take before the advair is totally out of my system? I am so tired of feeling so tired and sick. Please if anyone has experienced I'd like to know I am not alone.
