This medication is used to treat a certain skin condition (seborrheic dermatitis, a type of dandruff). In this condition, it is believed that a fungus (Malassezia furfur) infects the skin or scalp, resulting in dry, flaky skin (scales) on the scalp, face, ears, chest, or upper back. Ketoconazole is an azole antifungal drug that works by stopping the growth of fungus.
Read the Patient Information Leaflet provided by your pharmacist before you start using ketoconazole and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
