Onychomycosis is notoriously difficult to treat and cosmetically distressing. One in 4 patients don’t respond to therapy, and up to half of patients will experience relapse.Beyond efficacy issues, treatment options for onychomycosis come with certain risks. A 3- to 6-month regimen of oral antifungals comes with hepatotoxicity risk and a host of drug interaction possibilities. Most notably, the azole antifungals inhibit the most prevalent and critical hepatic enzyme (CYP3A4) in drug metabolism. Despite these interaction risks, oral therapy is more effective and takes up to 75% less time to complete than topical therapy. Cure rates for oral therapy fall between 45% to 70%, and total remission occurs for 35% to 80% of patients.
