Griseofulvin is an antifungal medication used to treat a number of types of dermatophytoses (ringworm). This includes fungal infections of the nails and scalp, as well as the skin when antifungal creams have not worked. It is taken by mouth.

Common side effects include allergic reactions, nausea, diarrhea, headache, trouble sleeping, and feeling tired. It is not recommended in people with liver failure or porphyria. Use during or in the months before pregnancy may result in harm to the baby. Griseofulvin works by interfering with fungal mitosis.

Griseofulvin was discovered in 1939 from the soil fungus Penicillium griseofulvum. It is on the World Health Organization's List of Essential Medicines.
