Superwarfarins have progressively replaced warfarin as rodenticides as they are more potent and have a longer anticoagulant activity. Human exposure may be complicated by spontaneous haemorrhage in various sites. We report the case of a 51-year-old woman who was admitted with spontaneous haemoperitoneum and intramural haematoma along the small intestine. After the evidence of a deficit of vitamin K1-dependent clotting factors (II, VII, IX, X), the patient admitted that she was chronically ingesting difenacoum. She was successfully treated with fresh frozen plasma and vitamin K1. Follow-up was not accepted.
