To treat itchy hands, it is important to identify the cause of the itchy hands. There are two causes: the first cause is tinea cruris caused by a fungal infection, which often occurs on one side of the hand, and requires laboratory tests for the fungus before treatment, as well as re-examination half a month and one month after treatment in order to see if the treatment is effective in terms of laboratory tests. Itraconazole capsules can be taken orally 1 time/day, 2 capsules/time. Or terbinafine hydrochloride tablets 1 time/day, 2 tablets/time and topical naftifine ketoconazole ointment, applied 2 times/day, followed by topical spray of terbinafine hydrochloride spray, 2 times/day. The second reason to consider eczema, mainly due to allergies, often symmetrically distributed, with unclear boundaries, can be treated with oral Orotadine Hydrochloride tablets 1 in the morning and 1 in the evening, and topical Denide ointment, applied 2 times/day.
