Ketoconazole is primarily used as an antifungal to treat fungal infections affecting the skin, such as athlete's foot and ringworm. Shampoos containing ketoconazole are also used to treat dandruff and seborrheic dermatitis. Ketoconazole is also used to treat certain systemic fungal infections affecting internal parts of the body.
Ketoconazole is sometimes used in certain conditions, such as oral candidiasis and vaginal yeast infections. Consult your doctor before using it to ensure proper use and to minimize any potential side effects.
