Ringworm is a fungal infection involving the skin. Several different types of fungi infect specific areas of the body. Common areas for ringworm include the body; scalp; groin, commonly referred to as jock itch; and the feet, also called athlete's foot. The fungus thrives in warm, moist environments and causes symptoms such as an itchy, red, ring-shaped rash on the skin. The affected areas may also cause pain, blisters and scaly patches. Using an antifungal cream on the skin helps treat the ringworm on the body, but the scalp may require oral antifungal medication.
Medications
Topical cream medications available to treat ringworm include clotrimazole, miconazole, tolnaftate and oxiconazole. These antifungal creams are available over the counter. Prescription antifungal creams such as terbinafine and ketoconazole may help treat a severe ringworm infection, according to MedlinePlus.
Application
Before applying any cream to a ringworm rash, the skin needs to be clean and dry. Cleansing with a mild soap and drying with a clean towel are sufficient. To use an antifungal cream on the rash, a thin layer of the cream needs to be spread over the entire affected area. For ringworm affecting the feet, the toes must be spread apart and the cream applied between them. The cream should be applied to the affected area one to two times each day or as frequently as prescribed by a physician.
Duration of Use
Use of the antifungal cream must be continued for two weeks. If the rash does not respond to the cream or worsens after two weeks, the individual should see a physician for evaluation. Applying antifungal medications to the affected areas may help prevent the spread of the infection. Continuing to use the antifungal cream for several weeks after the infection resolves helps prevent a recurrence of the infection.
Side Effects
Individuals using creams to treat a ringworm infection may experience a burning or tingling sensation on the skin after using the medication. An antifungal cream may cause dry skin, changes in skin color or thinning of the skin, according to RxList.com
Warnings
Bandages should not be placed over the rash unless directed by a physician. Loose-fitting, cotton clothes should be worn over the affected area to help improve air circulation and help combat the growth of the fungus. To prevent possible irritation, the cream should not get into the eyes, mouth or nose.
