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.

The side effects associated with taking Ketoconazole are typically mild. Most Ketoconazole side effects are associated with gastrointestinal discomfort.
