How to Get Rid of Ringworm: Treatment Options

Ringworm is not actually a worm—it's a common fungal infection that causes a ring-shaped, itchy rash on the skin. The good news is that ringworm is easy to treat. Most cases clear up within 2 to 4 weeks with the right antifungal medicine.

Over-the-Counter Treatments

For a single patch of ringworm on the body, over-the-counter antifungal creams work well. Look for products containing clotrimazole, miconazole, ketoconazole, or terbinafine. Apply the cream to the rash and a small area of healthy skin around it twice daily for 2 to 4 weeks.

Keep using the medicine for at least one week after the rash goes away. Stopping too early lets the fungus come back.

When You Need Prescription Medicine

See a doctor if your ringworm covers a large area, doesn't improve after 2 weeks, or keeps coming back. You also need prescription pills if ringworm affects your scalp or nails—creams don't work in these areas.

Oral antifungal medicines like terbinafine or itraconazole treat stubborn infections. Scalp ringworm requires 1 to 3 months of oral treatment.

What to Avoid

Never use steroid creams like hydrocortisone on ringworm. Steroids weaken your skin's ability to fight the fungus and make the infection spread. Only use antifungal medicines.

Preventing Spread

Ringworm spreads easily through skin contact and shared items. While treating the infection, keep the area clean and dry. Wash your hands after touching the rash. Don't share towels, clothes, or sports gear. Wash bedding and clothes in hot water.

When to See a Doctor

Contact a healthcare provider if the rash doesn't improve after 2 weeks of treatment or hasn't fully healed after 4 weeks. Also seek medical care if the infection is severe, spreading quickly, or appears on your scalp. Some newer strains of ringworm are resistant to common treatments and need stronger medicines.
