Treatment
Ringworm
Ringworm is treated with antifungal medications available over-the-counter (OTC) or by prescription. Treatments include:
Topical Antifungals
- Clotrimazole (Lotrimin®, Mycelex®)
- Miconazole (Desenex®)
- Terbinafine (Lamisil AT®)
- Tolnaftate (Tinactin®)
Topical treatments are usually effective for mild infections. They should be applied to the affected area for several weeks, continuing for at least one to two weeks after the visible rash has cleared to prevent recurrence.
Oral Medications
For more severe or widespread infections, oral antifungal medications may be prescribed for one to three months, including:
- Fluconazole
- Griseofulvin
- Itraconazole
- Terbinafine
Oral medications are particularly necessary for scalp ringworm and when the infection does not respond to topical treatments.
Antifungal Shampoo
Ketoconazole shampoo (Nizoral A-D®) may help stop the spread of scalp ringworm. While it won’t cure the infection, it can help contain it. Oral antifungal medication is also required for scalp ringworm. Unaffected family members may benefit from using the shampoo as a preventive measure.
Home Remedies for Ringworm
While some home remedies, such as apple cider vinegar and tea tree oil, are popularly believed to help, their effectiveness is not well-documented. Apple cider vinegar may cause open sores or inflammation, and tea tree oil, though having antifungal properties, is not a guaranteed cure.
Preventive Measures
- Maintain cleanliness: Regularly wash clothes, towels, and bed linens in hot water. Use disinfectant sprays on surfaces.
- Personal hygiene: Keep the affected area clean and dry. Wash hands frequently.
- Avoid sharing personal items: Do not share towels, clothing, or grooming tools.
- Wear loose-fitting clothes: Especially in warm, humid environments.
- Treat pets: Ensure pets are checked and treated for ringworm by a veterinarian.
