Summary
Effective ringworm treatment starts with OTC antifungal creams, sprays, or powders.
Keep the affected area clean and dry.
Even after symptoms are gone, continue treatment for at least two weeks.

For stubborn ringworm, prescription oral or topical antifungals may prove necessary.
With proper care, most cases clear in about two to four weeks.
