Ketoconazole is a topical antifungal medication prescribed for the treatment of fungal skin infections, including:
- tinea pedis (“athlete's foot”, a fungal infection of the skin on the feet and between the toes)
- tinea corporis (“ringworm”, a fungal skin infection that causes a red scaly rash on different parts of the body)
- tinea cruris (“jock itch”, a fungal infection of the skin in the groin or buttocks)
- tinea versicolor (a fungal infection that causes brown or light colored spots on the chest, back, arms, legs, or neck)
- Yeast infections of the skin
Ketoconazole shampoo may be used to treat the flaking, scaling, and itching of the scalp caused by seborrheic dermatitis.
Ketoconazole works by slowing the growth of fungi that cause infection.
Prescription ketoconazole comes as a cream and a shampoo to apply to the skin. Over-the-counter ketoconazole comes as a shampoo to apply to the scalp.
Ketoconazole cream is usually applied once a day for 2-6 weeks.
Ketoconazole is used at different frequencies depending on the condition being treated. Follow your prescription carefully.
If you are using ketoconazole cream, your symptoms should improve at the beginning of your treatment. Continue to use ketoconazole cream even if you are feeling well. If you stop using ketoconazole cream too soon, your infection may not be completely cured and your symptoms may return.
Ketoconazole cream and shampoos are only for use on the skin or scalp. Do not let ketoconazole cream or shampoo get into your eyes or mouth, and do not swallow the medication. If you do get ketoconazole cream or shampoo in your eyes, wash them with plenty of water.
To use the cream, apply enough cream to cover the affected area and all of the skin around it.
Take ketaconazole exactly as directed by your doctor. Do not take more or less of it or take it more often than prescribed by your doctor.
