Ringworm (Tinea Corporis):
A parent's guide to condition and treatment information

If you suspect that your child has ringworm, you might try one of the following over-the-counter antifungal creams or lotions:

• Terbinafine
• Clotrimazole
• Miconazole

Apply the cream to each lesion and to the normal-appearing skin 2 cm beyond the border of the affected skin for at least 2 weeks until the areas are completely clear of lesions. Because ringworm is very contagious, have your child avoid contact sports until lesions have been treated for a minimum of 48 hours. Do not allow your child to share towels, hats, or clothing with others until the lesions are healed.

Since people often have tinea infections on more than one body part, examine your child for other ringworm infections, such as on the face (tinea faciale), in the groin (tinea cruris, jock itch), or on the feet (tinea pedis, athlete's foot).

Have any household pets evaluated by a veterinarian to make sure that they do not have a dermatophyte infection. If the veterinarian discovers an infection, be sure to have the animal treated.
If large areas of the body are affected, or if the lesions do not improve after 1–2 weeks of applying over-the-counter antifungal creams, see your child's doctor for an evaluation.
