Medicament for treating onychomycosis

onychomycosis is commonly known as "onychomycosis". The drug selection for the treatment of onychomycosis can follow the following principles: if the affected nails are less than 4, amorolfine liniment can be applied externally once a week for half a year; if the affected nails are more than 4, the current treatment guideline is oral itraconazole capsules, twice a day, 200 mg once a week for 3 weeks, a total of 3~4 cycles; or terbinafine tablets orally, 0.25 g once a day for 3 months. Before and during treatment, liver and kidney function should be checked to ensure normal liver and kidney function before taking medicine.
