Metronidazole (topical)

About topical metronidazole

Metronidazole is used to treat bacterial infections. When used topically (which means that it is applied to the skin) it is used to treat infections of the skin such as rosacea (sometimes referred to as acne rosacea). It works by killing the bacteria responsible for the infection.

Metronidazole may also be used topically to reduce the odour from infected wounds such as skin ulcers.
