Coagulopathy associated with superwarfarin exposure

Abstract

A female patient with significant coagulopathy is presented for case discussion. This case represented a presumed Munchausen exposure to commercially available rat poison that contained one of the superwarfarin chemicals, brodifacoum. Review of the medical literature is undertaken to discuss the diagnostic approach and treatment of superwarfarin exposure. The accidental or intentional exposure to this group of rodenticide represents a significant public health problem that often is not considered by primary care physicians when confronted with coagulopathy.
