Antibiotics Home > Metronidazole Pills

Metronidazole (Flagyl®, MetroCream®, MetroGel®, MetroGel-Vaginal®, MetroLotion®, Noritate®, Vandazole®) is an antibiotic drug often used for the treatment of infections. Specifically, it is useful for infections caused by parasites and certain bacteria that do not require oxygen to survive (anaerobic bacteria). This medication is available by prescription only and comes in many different forms and strengths.
Some products are taken orally, while others are used topically. Metronidazole pills are available in the form of capsules and tablets (both short-acting and long-acting). The particular directions for when and how to use each product can vary substantially, so be sure to refer to the information for your specific medicine. Most metronidazole pills can be taken either with food or on an empty stomach; however, long-acting tablets must be taken on an empty stomach, at least one hour before or two hours after a meal.
