Foot odor is caused by fungal invasion of the skin keratin in the toe area, foot odor requires antifungal drugs, the specific treatment should be selected according to the type of foot odor and the shape of the rash, such as impregnated erosion type, local erosion and exudation, you can first use 3% boric acid solution or furacilin solution wet compress, and then apply antifungal drugs topically after the local dryness, like naftifine ketoconazole cream, terbinafine cream, Luliconazole cream, etc. If the foot odor is papular blister type or keratosis scales type, you can apply antifungal medication directly. For the keratinized scaly type, because the skin stratum corneum is thicker, the effect of simple topical medication is not good, you can take it orally with terbinafine or itraconazole to improve the cure rate.
