Onychomycosis can be treated with topical and oral medications. However, it is important to appropriately select these medications according to the type and severity of the disease and ensure treatment is continued for the recommended duration. In Japan, treatment options for onychomycosis have increased in recent years. Moreover, in 2019, the guidelines for dermatomycosis treatment were revised. In this study, we conducted a receipt survey to clarify the actual treatment status of onychomycosis cases as indicated by the continuation rates of prescribed treatment drugs, together with a web-based survey to ascertain the prescribing policy of dermatologists regarding drugs for onychomycosis treatment. In agreement with past surveys, this receipt survey showed that the prescription continuation rate for oral medications was higher than that for topical medications. The 1-year prescription continuation rate for topical onychomycosis medications was found to be low (<10%). The web-based survey showed that the percentage of physicians who prescribed oral medications as their first choice increased by approximately 10% for each disease type, compared with the results of the previous survey conducted around 7 years ago. However, the study also confirmed that topical drugs are still prescribed for some disease types for which oral drugs are better suited. To ensure complete cure without patient drop-out, oral drugs with a high probability of achieving complete cure and a high continuation rate should be prescribed for patients with onychomycosis.
