About Nizoral (ketoconazole)
Ketoconazole is an antifungal medication used to treat certain fungal infections. Like other azole antifungals, ketoconazole works by stopping the growth of fungus.
Ketoconazole is used to treat athlete's foot, jock itch, ringworm, pityriasis (tinea versicolor), and other fungal infections. Ketoconazole is available only by prescription. It is available in a generic formulation as well as under different brand names, including Nizoral.
Ketoconazole may be prescribed as a tablet, shampoo, or topical cream. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.
If you're prescribed ketoconazole, be sure to complete the full course of the antifungal treatment unless your doctor specifically tells you to stop. If you don’t complete your prescription, the antifungal may not fully treat your fungal infection.
Ketoconazole uses
There are several FDA-approved uses for ketoconazole, but your healthcare provider may also prescribe it off-label to treat other medical conditions.
Your PlushCare doctor may prescribe ketoconazole for any of the following reasons, or other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor or pharmacist.
Fungal infections
Ketoconazole is FDA-approved to treat fungal infections, including athlete's foot, jock itch, ringworm, and certain types of dandruff. Ketoconazole is also used to treat a fungal skin infection called pityriasis (tinea versicolor), which causes lightening and darkening of the neck, chest, arms, or legs.
Ketoconazole is not recommended for fungal infections of the fingernails or toenails. It's also not suitable for treating prostate cancer or Cushing syndrome.
