On Biaxin XL 1000mg, once daily for cellulitis skin infection from a 2nd degree burn. Not sure why my MD chose this. It is not the drug of choice for cellulitis. On day 2 of 6 days. Infection looks worse today than before Biaxin. I have a bitter, metallic taste in my mouth. Will give it another day or so, but feel pretty sure I will end up on a different antibiotic.
