I have been using Advair (250) for many years with no problems. We are remodeling out kitchen which has stirred up a lot of fine dust in the house. That coupled with the smoke caused by the recent forest fires in California I had a severe asthma attack. My doctor increased my Advair to 500. Within a week my voice left me. I have laryngitis of sorts and an accompanying cough that I can not shake. It has been nearly three weeks since it started and two weeks since I quite taking any Advair at all. How long does it take to recover from these symptoms after coming off Advair? I need my voice to function at work. Secondarily, after reading about cramping being a part of people's symptoms, I have had cramps in my legs feet and toes for several years-mainly at night. Hopefully being off Advair will resolve that as well.
