Ringworm is not caused by a worm at all. Instead, it is caused by infection with the tinea fungus, which also causes jock itch and athlete's foot. Ringworm causes itchy and red skin lesions that typically are brighter on their outside borders and clearer in the middle (giving them a ring-shape). Ringworm is very contagious and can easily spread between children if they share clothing or hats.
Step 1
Apply over-the-counter antifungal creams. These creams, which may contain the compounds terbinafine, miconazole or ciclopirox, work to kill fungi. They should be applied to the affected area once or twice per day. Keep the areas as clean and dry as possible after applying these ointments.
Step 2
Use prescription-strength antifungal creams. If your child's ringworm does not get better after 1 to 2 weeks with over-the-counter creams, ask your pediatrician for a prescription for some more potent ones. These creams contain the same active ingredients, just at a higher concentration and should be applied once or twice a day.
Step 3
Use oral antifungal medications. For some severe cases of ringworm, ointments alone are not sufficient to clear up the ringworm. In these cases, your pediatrician may prescribe oral medications. These typically come in pill form (though they may also come in the form of granules, which can be added to food). Oral antifungal medications include ketoconazole and terbinafine.
Step 4
Wash your child's clothing and bedding in hot water. This helps prevent the ringworm from spreading to other parts of the body or from reinfecting your child.
