Overview

Flagyl (metronidazole) is an antibiotic and antiprotozoal medication used to treat a variety of infections caused by bacteria and certain parasites. It is commonly prescribed for infections of the stomach, liver, skin, joints, brain, and respiratory tract, as well as for gynecological infections and certain sexually transmitted infections such as trichomoniasis.
