Ketoconazole is an antifungal medicine. It's used to treat skin infections caused by a fungus (yeast). It can also prevent them from coming back.
It treats different types of fungal infections including:
- athlete's foot
- jock itch, an infection in the groin area
- sweat rash (intertrigo), a rash that usually appears in folds of skin
- dandruff and seborrhoeic dermatitis, where your scalp or other areas of your skin become scaly and dry or greasy
- pityriasis versicolor, sometimes called tinea versicolour, where small patches of skin become scaly and change colour
