Foot odor and eczema are two different diseases. Foot odor is caused by fungal infection, usually occurs in the plantar area, and is not symmetrical. The treatment of foot odor is mainly topical antifungal drugs, such as naftifine ketoconazole cream, terbinafine cream, luliconazole cream, etc., and generally consolidate the treatment for at least one week after the rash subsides, and if necessary, oral antifungal drugs can also be taken to improve the efficacy. Eczema is an allergic disease and has nothing to do with fungal infections. Eczema is mostly symmetrical, with indistinct rash boundaries and significant itching. Eczema can be treated with oral anti-allergy medications such as loratadine or cetirizine, and topical anti-inflammatory creams such as Denide cream and mometasone furoate cream can be used topically. Some eczema can also be combined with fungal infections, and this time you can use topical compound preparations, such as trimethoprim cream and paregoric pine cream, which can treat both eczema and fungal infections.
