We report a case of terbinafine-induced agranulocytosis in a pediatric pati
ent. This effect was noted 4 weeks after starting terbinafine and resolved
within I week without the institution of therapy with granulocyte colony-st
imulating factor, a course similar to reports in adults. With the incidence
of severe side effects still unclear in children, this case argues for con
tinued blood surveillance during courses of terbinafine and for the confirm
ation of infection before initiation of the drug.
