Ok so i was taken off of Advair after 10 years, and switched to Symbicort because of my insurance company. Within 1 month of taking it i have developed severe laryngitis. I have tried throat spray, throat drops, tea wirh lemon, honey, zithromax, and salt water gargles which have offered no releif. I have been taken off the symbicort and put on dulera. But the laryngitis has persisted. This has been 4 three weeks now. Any suggestions?
