Topical Metronidazole

Metronidazole is a popularly used antibiotic to treat anaerobic bacteria, and in some cases, protozoa infections. Since at least 1980, dermatologists have been using this antibiotic as a way to treat roscaea symptoms.

Use:

Burning and irritation are the most common side-effects for topical use if this drug.
