In most cases, over-the-counter antifungal creams are effective in curing ringworm, states WebMD, specifically those including miconazole or clotrimazole, or other similar ingredients. In addition to using the cream, those infected with ringworm should also keep the area clean and dry, according to MedlinePlus.
In addition to using over-the-counter antifungal creams, WebMD suggests washing the infected area with soap and water, and applying Burow's solution to dry out the area and prevent the fungus from spreading. Washing all clothes and bed sheets during the infection also helps prevent it from spreading, states MedlinePlus.
However, more severe cases of ringworm infections may require antifungal pills or stronger antifungal creams, such as ketoconazole, explains MedlinePlus. Doctors may also prescribe antibiotics if a bacterial infection is present from too much scratching. Nevertheless, most ringworm infections clear up after four weeks of treatment with skin creams.
Ringworm spreads easily, either by touching someone who has the fungus, touching items that harbor the fungus, or through contact with pets, reports MedlinePlus. Cats are especially known for carrying ringworm. To prevent ringworm, keep skin and feet clean and dry, wash hair regularly, avoid sharing personal care items such as brushes and towels, and wear sandals at pools and gyms.
Common symptoms of ringworm include itchy, red and raised patches with sharply defined edges, states MedlinePlus.
