Athlete's foot, commonly known as tinea pedis, is an infection caused by dermatophyte fungi. Antifungal medications are required for symptomatic treatment. However, iodophors, as disinfectants, do not have a therapeutic effect on athlete's foot. Daily enhancement of foot hygiene, frequent changing of shoes and socks, and maintaining a dry and ventilated environment are important. Laboratory examinations, including scraping skin scales from affected areas for microscopic examination of fungi, are necessary. A positive laboratory result further supports the diagnosis of tinea pedis. Treatment involves the application of antifungal creams such as naftifine and ketoconazole. To adequately control symptoms and prevent recurrence, it may be necessary to take oral antifungal medications, such as terbinafine hydrochloride tablets, itraconazole dispersible tablets or capsules, for a treatment course of more than 2 weeks. (Medication should be used under the guidance of a doctor.)
