Tinea pedis is also known as ringworm of the feet, and both tinea pedis and tinea cruris are fungal infections, so the same antifungal creams can be used. The main causative agent of both tinea pedis and tinea cruris is the dermatophyte fungus, which can cause the disease by spreading it through one’s own hands and feet, and may also become ill through contact with the patient’s personal belongings. It is more likely to occur in people who sweat a lot, wear tight clothing, share towels with others, and have weakened immune systems. When patients find tinea pedis or tinea cruris, they should actively cooperate with the doctor to remove the pathogenic bacteria, and can be given antifungal ointment treatment, commonly used drugs include miconazole, econazole, ketoconazole, clotrimazole and so on. If necessary, add oral terbinafine, itraconazole and other antifungal drugs to improve the therapeutic effect. If diagnosed with foot and ringworm disease, should be early standardized treatment to reduce the adverse effects of the disease. All of the above drugs should be used under the guidance of a doctor.
