Ringworm

Alternative names:

dermatophytid; tinea

Treatment:

Ringworm usually responds to self-care. Keep the skin clean and dry. Over-the-counter antifungal or drying powders, lotions, or creams are applied to the affected skin. Those that contain miconazole, clotrimazole, or similar ingredients are often effective in controlling ringworm.

Severe or persistent infection may require further treatment by the health care provider. Oral antifungal medications may be given. Stronger, prescription topical antifungal medications, such as ketoconazole or sulconazole may be needed. In some cases, topical corticosteroids (see corticosteroids - topical - low potency and corticosteroids - topical - medium to very high potency) may be added to the topical antifungals. Antibiotics may be needed to treat secondary bacterial infections.

Expectations (prognosis):

Ringworm usually responds to topical treatment within 4 weeks. Severe or resistant cases usually respond promptly to oral antifungal therapy.

Complications:

• secondary bacterial skin infections, cellulitis
• spread of tinea to feet, scalp, groin, nails, or other area
• pyoderma, dermatophytid, or other skin disorders
• overtreatment dermatitis
• systemic side effects of medications (See the specific medication)

Calling your health care provider:

Call for an appointment with your health care provider if ringworm does not improve with self-care, or if symptoms persist longer than 4 weeks.
