Tinea corporis, commonly known as ringworm, is a fungal infection that affects the top layer of the skin. People suffering from ringworm develop a red itchy circular patch on the skin. You may have one or multiple ringworm patches on the skin at a time.
Ringworm is a highly contagious infection. Exposure to the ringworm fungus from physical contact with a person suffering from the infection or using clothing or other items of the patient contaminated with the fungus causes ringworm.
Ringworm is treated with antifungal medications. Mild to moderate ringworm usually respond to over-the-counter antifungal ointments. Severe infections may require prescription drugs that are either used topically or taken orally to cure the fungal infection.
Medications to Treat Ringworm
Miconazole
Miconazole ointment, lotion, spray liquid or powder is available over-the-counter for treating ringworm. It is usually applied twice a day to the ringworm patches for one to two months or as instructed by your dermatologist.Itching, burning and irritation of the treated skin are some of the common side effects of the drug.
Clotrimazole
Clotrimazole is used topically to clear the ringworm patches. It is available over-the-counter in the form of ointment, powder and lotion. It is usually applied to the affected area of the skin twice daily for two to eight weeks. Itching, irritation, redness, burning and swelling of the treated area are some possible side effects of the drug. A prescription medicine that combines clotrimazole with corticosteroid betamethasone is sometimes recommended by dermatologists for treating ringworm that causes intense itching and burning and is inflamed. While the antifungal treats the infection, the corticosteroid reduces the inflammation.
Ketoconazole
Ketoconazole is applied on the ringworm patch to heal the infection. It works by destroying the fungi and inhibiting their growth. As fungal infections heal slowly, it may take several weeks to cure ringworm with the antifungal cream.Your dermatologist may ask you to continue applying the antifungal cream to the affected area even after the ringworm patch clears. Irritation, burning, stinging and itching of the treated area are some common side effects of the drug.
