sinusitis
"I too have had multiple sinus infections and surgery twice. In addition I am immunosuppressed because of a medication for rheumatoid arthritis. Biaxin has always worked for me. I really have no side effects other than the metallic taste which is tolerable. I make sure I take it after food otherwise it is really hard on the stomach. I take Biaxin XL 500mg, 2 tablets once a day for 14 days."
