Over-the-counter antifungal powders or creams can help control the infection:
These contain medicine such as miconazole, clotrimazole, terbinafine or tolnaftate.
Keep using the medicine for 1 to 2 weeks after the infection has cleared to prevent it from returning.
Keep your feet clean and dry, especially between your toes.
Wash your feet thoroughly with soap and water and dry the area carefully and completely. Try to do this at least twice a day.
To widen and keep the web space (area between the toes) dry, use lamb's wool. This can be bought at a drugstore.
Wear clean cotton socks. Change your socks and shoes as often as needed to keep your feet dry.
Wear sandals or flip-flops at a public shower or pool.
Use antifungal or drying powders to prevent athlete's foot if you tend to get it often, or you frequent places where athlete's foot fungus is common (like public showers).
Wear shoes that are well-ventilated and made of natural material such as leather. It may help to alternate shoes each day, so they can completely dry between wearings. Do not wear plastic-lined shoes.
If athlete's foot does not get better in 2 to 4 weeks with self-care, or frequently returns, see your health care provider. Your provider may prescribe:
Medicines to take by mouth
Antibiotics to treat bacterial infections that occur from scratching
Athlete's foot almost always responds well to self-care, although it may come back. Long-term medicine and preventive measures may be needed.
When to Contact a Medical Professional
Call your doctor right away if:
Your foot is swollen and warm to the touch, especially if there are red streaks. These are signs of a possible bacterial infection. Other signs include pus, drainage, and fever.
You have diabetes or a weakened immune system and develop athlete's foot.
Athlete's foot symptoms do not go away within 2 to 4 weeks of self-care treatments.
