Have Thrush From Using Advair For Months And Months. Allergic

Have thrush from using Advair for months and months. Allergic to the meds that are supposed to clear it. Now having throat problems; burns but not always, itches but not always, hurts to talk or sing, throat always feels dry and irritated. Please let me know what I can do. I also tried the purple liquid that stains everything; it did not work either.
