Concepts in Onychomycosis Treatment and Recurrence Prevention: An Update.

In considering therapy for onychomycosis, the most important factor to take into account is patient selection rather than treatment selection. Patients should be screened and evaluated for the extent of nail involvement, the amount of subungual debris, the degree of dystrophy, their ability and willingness to follow the regimen, and whether comorbidities are present that may affect the efficacy and/or safety of one or more therapies. Onychomycosis is a chronic disease with a high recurrence rate. Commonsense measures to reduce the risk for reinfection include patient education and a clinician-patient team approach to long-term management.
