Terbinafine is an allylamine fungicidal agent that is widely used for the treatment of onychomycoses and other fungal infections. Adverse effects may occur in more than 10% of patients receiving oral terbinafine, with cutaneous reactions in 2.7%. We describe the development of acute generalized exanthematous pustulosis in a 36-year-old woman who took oral terbinafine.
