What is the treatment for Ringworm?
Ringworm usually responds well to self-care within four weeks without having to see a doctor.
- Keep your skin clean and dry.
- Apply over-the-counter antifungal or drying powders, lotions, or creams. Those that contain miconazole, clotrimazole, or similar ingredients are often effective.
- Wash sheets and nightclothes every day while infected.
A severe or persistent infection may require treatment by a doctor. Antifungal pills may be given and are necessary if your hair is infected. Prescription antifungal skin medications, such as ketoconazole, are stronger than over-the-counter products and may be needed. Antibiotics may also be needed to treat related bacterial infections.
Infected pets also should be treated.
Ringworm can be treated with fungus-killing medicine. The medicine can be in taken in tablet or liquid form by mouth or as a cream applied directly to the affected area.

Is Ringworm an emerging infection?
Although Ringworm is not tracked by health authorities, infections appear to be increasing steadily, especially among pre-school and school-age children. Early recognition and treatment are needed to slow the spread of infection and to prevent re-infection.
How can Ringworm be prevented?
Ringworm is difficult to prevent. The fungus is very common, and it is contagious even before symptoms appear.
Steps to prevent infection include the following:
- Educate the public, especially parents, about the risk of Ringworm from infected persons and pets.
- Keep common-use areas clean, especially in schools, day-care centers, gyms, and locker rooms. Disinfect sleeping mats and gym mats after each use.
- Do not share clothing, towels, hair brushes, or other personal items.
Infected persons should follow these steps to keep the infection from spreading:
- Complete treatment as instructed, even after symptoms disappear.
- Do not share towels, hats, clothing, or other personal items with others.
- Minimize close contact with others until treated.
- Make sure the person or animal that was the source of infection gets treated.
