To treat ringworm effectively, follow these steps:
- Use antifungal medications: For most cases of ringworm on the body, over-the-counter (OTC) antifungal creams, lotions, gels, or powders such as clotrimazole, miconazole, terbinafine, or ketoconazole are recommended. Apply these to the affected area and about 2 cm beyond the rash, usually twice daily for 2 to 4 weeks, even if symptoms improve earlier
- Keep the area clean and dry: Moisture encourages fungal growth, so wash the area gently and keep it dry. Wear loose, breathable clothing to allow the skin to breathe and speed healing
- Avoid corticosteroid creams: Do not use creams containing steroids, as these can worsen the infection
- Wash bedding and clothes regularly: Since ringworm is contagious, wash clothes, towels, and bedding in hot water with detergent daily to prevent spreading
- For scalp ringworm (tinea capitis): This usually requires prescription oral antifungal medication along with antifungal shampoo (e.g., ketoconazole or selenium sulfide) to control the infection and prevent spreading. Antifungal shampoos alone do not cure scalp ringworm but help contain it
- When to see a doctor: If symptoms worsen or do not improve after 2 weeks of treatment, if the infection is widespread, on the scalp, or if you have a weakened immune system, consult a healthcare provider. They may prescribe oral antifungal medications for more severe or persistent infections
In summary, ringworm treatment involves consistent application of antifungal medication, maintaining hygiene and dryness, and possibly prescription medication for more severe cases or scalp involvement. Treatment duration is typically at least 2 to 4 weeks to ensure full eradication of the fungus
