Onychomycosis treatment in the United States.

Onychomycosis is a common progressive infection of the nails that may result in remarkable morbidity. Although there are a variety of treatments available for fungal nail infections with different efficacy and safety profiles, there are limited reports on the ways in which physicians use these treatments or the frequency with which they prescribe them. In this retrospective study, major trends in the prescription and use of antifungal agents for treatment of onychomycosis in the United States were evaluated using data from the National Ambulatory Medical Care Survey. Results showed that current treatment and trends in use of drugs for onychomycosis in the United States are in accordance with recommendations in current guidelines.
