Nizoral is used to treat a variety of fungal infections in the body. It treats fungal infections of the skin, such as ringworm, athlete foot, and jock itch. It also treats fungal infections of the scalp, including dandruff caused by a fungal infection.
It also treats fungal infections in other areas of the body, such as nails or sensitive areas. Nizoral sometimes helps control certain skin disorders caused by fungi, such as seborrheic dermatitis. Nizoral is used either as tablets taken orally or as a cream, gel, or shampoo applied topically to the affected areas, depending on the type and severity of the infection.
