Ketoconazole is an antifungal medication available in oral and topical forms, commonly used to treat a variety of fungal infections such as athlete’s foot, jock itch, ringworm, and nail infections caused by fungi or yeast. It is also utilized to manage seborrheic dermatitis and dandruff, particularly when associated with the overgrowth of Malassezia fungus on the scalp. Often prescribed by healthcare professionals, ketoconazole should be used according to their instructions to ensure effectiveness and minimize the risk of side effects. It’s important to complete the full course of treatment as directed, even if symptoms improve, and to discuss any concerns or potential interactions with other medications with a healthcare provider.
