DRUG CLASS AND MECHANISM: Griseofulvin is an oral antibiotic that is used to treat fungal infections of the skin, body, hair/beard, or nails. Griseofulvin prevents fungal cells from dividing and multiplying. Griseofulvin also is deposited in keratin cells on the surface of the skin making it difficult for fungus to invade the skin and other tissues. Griseofulvin is effective against Microsporum, Epidermophyton and Trichophyton. It is not effective against bacteria. The FDA approved griseofulvin in 1959.
