In 2013, as part of the Choosing Wisely® initiative from the American Board of Internal Medicine Foundation (ABIM), the American Academy of Dermatology (AAD) released recommendations regarding low-value care that cautioned against prescribing oral antifungal therapy for suspected nail fungus without confirmation of fungal infection. The AAD concluded that about half of suspected fungal infections are not fungal infections and starting patients on treatment before confirming diagnosis could unnecessarily expose them to the adverse effects of antifungal therapy. Although the diagnosis of onychomycosis can be made clinically, it is important to confirm this with a nail clipping and with a periodic acid-Schiff or a fungal culture.

Daily terbinafine (250 mg for 3 months) had a 70.9% mycologic cure, while pulse-dose terbinafine (500 mg daily for 1 week per month for 3 months) had only a 58.7% mycologic cure (relative risk [RR]=1.21 [95% CI, 1.02–1.43]; NNT=8.2). Long-term effectiveness of treatment vs itraconazole in onychomycosis: a 5-year blinded prospective follow-up study. A multicenter trial of diabetic patients with onychomycosis (mean±SD age, 55.7±11.7 years) revealed that terbinafine had comparable efficacy and caused no hypoglycemic reactions in this group, who were being treated with insulin or oral hypoglycemics.

A 5-year blinded prospective study found long-term mycologic cures of 46% for terbinafine vs 13% for itraconazole (number needed to treat [NNT]=4.3). Longer-term mycologic cure and clinical relapse rates have also been reported. Another meta-analysis of 6 studies comparing terbinafine with itraconazole reported odds ratios ranging from 1.8 (95% confidence interval [CI], 1.1–2.8) to 2.9 (95% CI, 1.9–4.1), indicating an 80% to 190% increased likelihood of clinical cure with terbinafine compared with itraconazole.
