Abstract

|
Superwarfarin intoxications that induce profound and prolonged coagulopathy are being increasingly reported, to such an extent that it is becoming a comparatively common intoxication. However, there have been few reported cases of superwarfarin intoxication with an inadvertent cause or an unknown origin. A 58-year-old man with recurrent painless hematuria was found to have an acquired deficiency of vitamin K dependent clotting factors, and a large amount of vitamin K was required to correct the coagulopathy. He had no history of warfarin use or any exposure to rodenticides, but brodifacoum was detected in his serum. It is important for physicians to be aware that significant coagulopathy can occur secondary to superwarfarin intoxication, without any known exposure to substances that might induce this.
