  • It is a common malady, with up to 70% of the adult population having it at some point in their lives.

Symptoms

HOME CARE ADVICE

General Care Advice for Athletes Foot
  1. Antifungal Cream. Apply the antifungal cream 2 times a day to the affected areas of the feet. Continue the cream for at least 7 days after the rash is cleared.
    • Available over-the-counter in U.S. as terbinafine (Lamisil AT) or clotrimazole (Lotrimin AF) or miconazole (Micatin, Monistat-Derm).
    • Available over-the-counter in Canada as clotrimazole (Clotrimazole cream, Canesten, Clotrimaderm) or miconazole (Micatin Cream, Micozole, Monistat-Derm).
    • Terbinafine (Lamisil AT) is most recommended, but is not available in Canada.
    • Read the package instructions thoroughly on all medications that you use.
  2. Keep the Feet Clean and Dry: Wash the feet two times every day. Dry the feet completely, especially between the toes. Then apply the cream. Wear clean socks and change them twice daily.
  3. Avoid Scratching: Scratching infected feet will delay healing. Rinse the itchy feet in cool water for relief.
  4. Contagiousness: The condition is not very contagious. The fungus can't grow on dry, normal skin. Adults with Athlete's Foot do not need to miss any school or work. You can continue to play sports. The socks don't need to be boiled.
  5. Expected Course: With proper treatment, Athlete's Foot should decrease substantially within 1 week and disappear within 2 weeks.
  6. Call Your Doctor If:
    • Rash looks infected (e.g., spreading redness, streaks, pus)
    • Rash continues to spread after 1 week of treatment
    • Rash has not cleared after 2 weeks of treatment
    • You become worse
Prevention
  1. Avoid Being Barefoot in Public Areas (e.g., showers, bathrooms, swimming pools). You can get athlete's foot from walking barefoot in these areas. Wear sandals.
  2. Keep the Feet Clean and Dry:
    • Wash your feet with warm soapy water once a day. Rinse the feet and dry thoroughly, especially between the toes.
    • Wear clean cotton socks and change daily.

And remember, contact your doctor if you develop any of the "Call Your Doctor" symptoms.
