Ringworm (Tinea Corporis):
Information for adults

If you suspect that you have 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 area is completely clear of the lesion. Because ringworm is very contagious, avoid contact sports until lesions have been treated for a minimum of 48 hours. Do not 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 yourself for other ringworm infections, such as on the face (tinea faciale), in the beard area (tinea barbae), 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 fungal (ie, 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 doctor for an evaluation.
