Athlete's Foot - Treatment Overview
How you treat athlete's foot (tinea pedis) depends on its type and severity. Most cases of athlete's foot can be treated at home using an antifungal medicine to kill the fungus or slow its growth.
- Nonprescription antifungals usually are used first. These include terbinafine (Lamisil AT), miconazole (Micatin), clotrimazole (Lotrimin AF), and tolnaftate (Tinactin). Nonprescription antifungals are applied to the skin (topical medicines).
- Prescription antifungals may be tried if nonprescription medicines are not successful or if you have a severe infection. Some of these medicines are topical antifungals, which are put directly on the skin. Examples include naftifine (Naftin), butenafine (Mentax), miconazole (Monistat Derm), and clotrimazole (Lotrimin). Prescription antifungals can also be taken as a pill, which are called oral antifungals. Examples of oral antifungals include terbinafine (Lamisil), itraconazole (Sporanox), and fluconazole (Diflucan).
For severe athlete's foot that doesn't improve, your doctor may prescribe oral antifungal medicine (pills). Oral antifungal pills are used only for severe cases because they are expensive and require periodic testing for dangerous side effects. Athlete's foot can return even after antifungal pill treatment.
Although your symptoms may decrease or stop shortly after you begin using antifungal medicine, it is important to complete the full course of medicine. This increases the chance that athlete's foot will not return. Reinfection is common, and athlete's foot needs to be fully treated each time symptoms develop.
Toe web infections
Toe web
(interdigital)
infections occur between the toes, especially between the fourth and fifth
toes. This is the most common type of athlete's foot infection.
- Treat mild to moderate toe web infections by keeping your feet clean and dry and using nonprescription antifungal creams or lotions.
- If a severe infection develops, your doctor may prescribe a combination of topical antifungal creams plus either oral or topical antibiotic medicines.
Moccasin-type athlete's foot infection
Moccasin-type
athlete's foot causes scaly, thickened
skin on the sole and heel of the foot. Often the toenails become infected
(onychomycosis). A moccasin-type infection is difficult
to treat because the skin on the sole of the foot is very thick.
- Nonprescription medicines may not penetrate the thick skin of the sole well enough to cure moccasin-type athlete's foot. In this case, a prescription topical antifungal medicine that penetrates the sole, such as ketoconazole, may be used.
- Prescription oral antifungal medicines are sometimes necessary to cure moccasin-type athlete's foot.
Vesicular infections
Vesicular
infections, or blisters, usually appear on
the foot instep but can also develop between the toes, on the sole of the foot,
on the top of the foot, or on the heel. This type of fungal infection may be
accompanied by a bacterial infection. This is the least common type of
infection.
Treatment of vesicular infections may be done at your doctor’s office or at home.
- Your doctor may remove the tops of the blisters and soak your foot until the blister area is dried out.
- You can dry out the blisters at home by soaking your foot in nonprescription Burow's solution several times a day for 3 or more days until the blister area is dried out. After the area is dried out, use a topical antifungal cream as directed. You can also apply compresses using Burow's solution.
- If you also have a bacterial infection, you will most likely need an oral antibiotic.
- If you have a severe infection, your doctor may prescribe corticosteroid pills. After improvement, corticosteroid pills are gradually stopped, and antifungal creams and/or pills are used until the infection is gone.
