What is the first treatment tried for ringworm?

Ringworm, also called tinea corporis, is caused by fungi rather than a worm. A topical antifungal works at the skin surface where the infection is active. Treatment choice can change if the rash is widespread, involves the scalp or nails, keeps returning, or does not improve as expected. Those situations may require an examination and an oral antifungal medicine. Other rashes can look similar, so a clinician may confirm the diagnosis before changing treatment.

Use the recommended antifungal exactly as directed and apply it to the rash and the surrounding skin if instructed. Keep the area clean and dry, wash hands after applying medicine, and avoid sharing towels, clothing, or sports equipment. Wash fabrics that touch the rash regularly and avoid scratching. Do not use a steroid cream alone on a rash that might be ringworm, because it can alter the appearance and allow the fungal infection to persist.

Arrange a medical review if the rash is on the scalp or nails, affects a large area, becomes painful or oozy, spreads despite correct treatment, or returns repeatedly. Seek prompt help for facial swelling, severe tenderness, fever, or a rapidly worsening rash. A child, pregnant person, or someone with reduced immunity may need personalised treatment advice.

Ask whether the appearance confirms ringworm, how long to use the topical medicine, whether household contacts need checking, and whether oral treatment is appropriate for the body site involved.
