Sinusitis
"I have been on Biaxin for about 7 days for sinus infection and bronchitis. I started to feel better after a couple of days, but don&#039;t feel as good. Still coughing and stuffed up on one side. Side effects haven&#039;t been too bad - metallic taste in mouth for some time after I take it, but goes away. Also makes me a little nauseous if I don&#039;t take with food. Wondering if I need to go back to the Dr. though."
