Metronidazole (Flagyl) is an antibiotic and antiparasitic medication. It can be used both topically and orally to treat certain types of infection.
Metronidazole is occassionally used as a treatment for acne. Metronidazole is usually applied topically when used for the treatment of acne symptoms.
Metronidazole has been reported by some patients to improve their acne symptoms. But the use of Metronidazole as an acne treatment is somewhat controversial. On one hand, several clinical studies have reported that topical Metronidazole is an effective treatment for acne, especially a specific type of acne – Acne Rosacea. On the other hand, laboratory testing has consistently indicated that the acne-causing P. acnes bacteria is naturally resistant to Metronidazole.
Continued clinical investigation and patient surveys will be required to determine the utility of Metronidazole for the treatment of acne.
