If you have athlete’s foot or tinea pedis, you can choose the appropriate topical medication, but if it is stubborn or combined with gray nails, you need to take oral antifungal medication, as follows. Tinea pedis, commonly known as “athlete’s foot”, is also known as “athlete’s foot” because of the odor that often accompanies bacterial infections. Because the feet are moist and sweaty, it is conducive to the growth of fungi, especially when combined with onychomycosis, and the persistence of spores and mycelium can repeatedly trigger and aggravate tinea pedis. According to statistics, about 50% of people with tinea pedis have a combination of onychomycosis. In this case, curing onychomycosis is a prerequisite for curing tinea pedis. Treatment of onychomycosis is based on oral antifungal medication, choosing itraconazole capsules or terbinafine tablets, which requires avoidance of alcohol and testing of liver function during treatment, for a total of 3-4 months and costs around $1,000. If you feel that you cannot adhere to it, or if the fungal infection only accumulates on the skin, topical medication can be the mainstay. For hypertrophic keratotic type, topical compound benzoic acid ointment is used. For toe crevice vesicular impregnation, apply cold and wet compresses with compound cypress solution and boric acid solution, reduce exudation and then apply topical astringent with ketoconazole powder and zinc oxide powder, and change to ketoconazole cream after drying. If you do not have the above-mentioned condition, and it is only the blistering type, it is recommended to apply ketoconazole cream topically directly and insist on full 4 weeks. It is easy to control the symptoms of tinea pedis, but it is difficult to cure and easy to repeat. Finding the cause of recurrence and improving hygiene habits are helpful to improve the cure rate.
