Go Over-the-Counter for 25 Days
Topical creams from your drugstore are a good place to start when treating Athlete's Foot — look for ones that contain anti-fungal agents terbinafine or clotrimazole, such as Lamisil ($11, drugstore.com) and Lotrimin ($13, drugstore.com) and apply twice a day, for a full 25 days. "That's the length of time it takes for the old skin to turn over and you won't know whether it's worked until the new skin comes in," Morse says. If nonprescription products aren't having the desired effect after a full cycle, it's time to see your doctor. Often, you will need an oral antifungal pill to kill off the buggers for good.
