Jock itch is the common name for tinea cruris, a fungal infection of the skin of the inner thighs, buttocks and genitals, according to MayoClinic.com. This infection is most likely to occur in people who have moisture on the thighs, such as that caused by sweating. Symptoms of jock itch include redness, itching and a ring-shaped rash. Several over-the-counter and prescription topical antifungal medications are available to treat jock itch.
Terbinafine is the generic name for an antifungal agent used to treat jock itch, athlete's foot and ringworm. This cream should be applied directly to the affected area at least once a day or as directed by the package or a doctor. Before applying a thin layer of cream, the athlete should wash the affected area with soap and water and pat it dry.
Naftifine is the generic name of an antifungal cream used to treat jock itch. Drugs.com points out that the way naftifine works is not fully understood but it is presumed to inhibit the production of an enzyme that allows the fungus to live. This cream should be used only for as long as directed. If the infection does not clear up after four weeks, a prescription medication may be necessary.
Miconazole is a cream available over-the-counter and can relieve the symptoms of jock itch infection, including itching, scaling or burning. The ingredients in the creme kill the fungus. Drugs.com explains that the cream weakens the cell membrane of the fungus, which leads to its death. The cell membrane is what holds the cell together and allows it to function. Like other over-the-counter antifungal creams, miconazole should be used as directed. If the infection does not disappear after four weeks, medical treatment is necessary.
Econazole is a prescription strength antifungal cream that works by interfering with the formation of the fungal cell membrane and weakening it, explains Drugs.com. This cream should only be used as directed by a health care provider. Some patients using econazole may experience mild side effects including burning, itching, redness or stinging at the site of application.
Oxiconazole is a prescription antifungal cream that is used to treat athlete's foot, jock itch or ringworm. It works, according to Drugs.com, by preventing the growth of the fungus. This drug should be used as directed and should only be applied to the affected area after it has been washed and dried thoroughly.
