Ketoconol-5 Cream is an antifungal medication used to treat skin fungal infections like athlete's foot, thrush, and ringworm. It should be used according to your doctor's prescribed dose and duration, and not used more than needed. Skin infections usually improve after 2 to 4 weeks, and if not, contact your doctor. If you have athlete's foot, wash your socks or tights thoroughly and change your shoes daily. Common side effects include application site reactions, dryness, peeling, or blistering of the skin, and thinning of hair. Avoid direct contact with your eyes and seek medical attention if necessary.
