Tinea pedis refers to tinea pedis, which is a common inflammatory skin reaction caused by fungal infection. In clinical practice, if a patient has severe tinea pedis, it is recommended that oral treatment with antifungal medications be applied along with topical antifungal medications. Itraconazole and terbinafine are commonly used orally, and ketoconazole ointment, miconazole ointment, and terbinafine cream are used topically. If the patient has obvious local rupture erosion type of foot odor patients, need to apply boric acid solution or dilute potassium permanganate solution, lactic acid escharacridine solution for wet compresses. After the local exudation is reduced, then miconazole nitrate powder is applied to the area, and after the local healing is better, then ointment-type antifungal drugs are applied topically. It is important that the treatment of tinea pedis is adequate and that the patient does not stop taking the medication as soon as the symptoms are slightly reduced.
