Athlete's foot, also known as tinea pedis, is a relatively common fungal skin infection. There are multiple types of athlete's foot, with toe web infection, moccasin-type infection and vesicular infections being the most common. With a typical toe web infection, the skin between toes peels or cracks. Moccasin-type infections also cause peeling and cracking, but on the bottom of the foot rather than the toes. Vesicular infections differ significantly: they begin with large, fluid-filled blisters usually on the top of the foot.

In most cases, treatment for athlete's foot is available over the counter. Nonprescription antifungals are available in cream forms to be spread directly on the affected areas. Nonprescription treatments for athlete's foot include tolnaftate (sold under the brand names of Tinactin® and Tinaderm®), miconazole (Micatin®), terbinafine (Lamisil AT®) and clotrimazole (Lotrimin AF®).

If a case of athlete's foot is especially severe, or is not improved after treatment with nonprescription medication, doctors may prescribe stronger antifungals, which can come in similar forms to the nonprescription creams or as pills intended to be taken orally. Many prescription treatments for athlete's foot are simply higher dosages of the same medications available over the counter, although itraconazole (Sporanox®), fluconazole (Diflucan®), and butenafine (Mentax®) are also used.

Most doctors are reluctant to prescribe oral antifungal medication unless a case of athlete's foot is severe because they are expensive and can cause significant side effects. Patients on these medications must be monitored and may need periodic testing for such side effects.

There are a wide variety of home remedies that have been used to treat athlete's foot. However, not all have been thoroughly researched, and should be considered with caution. Home remedies can include the use of tea tree oil, which is available at most health food stores, as well as washing feet in any of number of solutions. Rubbing alcohol, vinegar, weak bleach mixture, garlic mixed with water, boric acid and raw honey have all been suggested as treatments for athlete's foot.

Athlete's foot can reemerge even after treatments with powerful antifungals. To prevent athlete's foot, consider wearing sandals or shower shoes in lockers and other shared facilities. Keep your feet dry and wear shoes that allow for maximum airflow. Talcum powder can help keep your feet dry, reducing the opportunity for fungus to flourish.
