Athlete's Foot - Treatment Overview
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.
Even when treated, athlete's foot often returns. This is likely to happen if:
- You don't take preventive measures and are again exposed to the fungi that cause athlete's foot.
- You don't use antifungal medicine for the specified length of time and the fungi are not completely killed.
- The fungi are not completely killed even after the full course of medicine.
You can prevent athlete's foot by:
- Keeping your feet clean and dry.
- Dry between your toes after swimming or bathing.
- Wear shoes or sandals that allow your feet to breathe.
- When indoors, wear socks without shoes.
- Wear socks to absorb sweat. Change your socks twice a day.
- Use talcum or antifungal powder on your feet.
- Allow your shoes to air for at least 24 hours before you wear them again.
- Wearing shower sandals in public pools and showers.
What to think about
You may choose not to treat athlete's foot if your symptoms don't bother you and you have no health problems that increase your chance of severe foot infection, such as diabetes. But untreated athlete's foot that causes skin blisters or cracks can lead to severe bacterial infection. Also, if you don't treat athlete's foot, you can spread it to other people.
Severe infections that appear suddenly (acute) usually respond well to treatment. Long-lasting (chronic) infections can be more difficult to cure.
Toenail infections (onychomycosis) that can develop with athlete's foot tend to be more difficult to cure than fungal skin infections. For more information, see the topic Fungal Nail Infections.
