If a person with foot fungus is found to have erosions between the toes, direct topical application of Dacronin is usually not recommended for treatment. Foot fungus, known clinically as tinea pedis, is a common fungal infection causing inflammation of the skin. Dakinin is a commonly used azole antifungal drug in an ointment formulation. It is not advisable to apply Dacrynicin topically directly at this time, as it will make the erosion and exudation more serious. For foot odor with interdigital erosion, it is usually recommended to apply a wet compress with 3% boric acid solution or ezacridine lactate solution first. When the exudation is reduced and the erosion is lighter, then miconazole powder is sprinkled locally, and after the local erosion has healed and the skin has dried, creams and ointments such as Dakin are used for external application. During the treatment of foot fungus, patients’ shoes and socks should be disinfected, either by sunlight exposure or boiling water. At the same time, it is not recommended that patients do not use drugs indiscriminately, but regularly under the guidance of a doctor.
