Keratosis pilaris is also known as scaly keratosis pedis, and it chooses drugs first of all antifungal drugs. Because it has a thicker cuticle, you need to choose one with better permeability, such as bifidazole solution and miconazole nitrate spray, for treatment. The treatment course is usually about 4 weeks, because the metabolism of this layer of the skin is usually 28 days. So from the basal layer of the epidermis of the foot, gradually to the metabolic cycle of the stratum corneum, it takes 4 weeks to fully kill the fungus, 2 times a day, 1 time in the morning and 1 time in the evening. If it is longer and more stubborn, oral antifungal drugs can be recommended for treatment, such as terbinafine hydrochloride tablets or itraconazole capsules. It is recommended to choose the latter, which has a broader antibacterial spectrum, and the treatment will be sufficient for about two weeks. Liver function monitoring is performed before and after treatment respectively, so that it is safer to use under the condition of ensuring normal liver function, because this drug has a certain effect on the liver.
