What is Metronidazole (Flagyl)?

Metronidazole is an antibiotic and antiprotozoal medication used to treat a wide range of infections caused by bacteria and parasites. It is commonly prescribed for conditions such as bacterial vaginosis, trichomoniasis, giardiasis, and certain types of abdominal infections.
