Abstract
Superwarfarin (long-acting anticoagulant rodenticide) poisoning should be suspected in unexplained bleeding with prolonged prothrombin time, especially in the absence of another explanation. Diagnosis and treatment of this intoxication remain a challenge as the direct analysis of superwarfarin in serum is not always possible. Therefore, toxin bioavailability remains unknown and close monitoring and treatment for long periods are required to avoid serious bleeding complications. Here, we discuss a case of suspected superwarfarin poisoning to highlight the challenges in early diagnosis and the challenges we encountered in treatment management and ensuring compliance for long periods.

Contributors AdGG and GMGS conceived the presented idea. This was also discussed with AHG who encouraged AdGG and GMGS to investigate superwarfarin poisoning and supervised the findings of this work as well as helped with the planning. AdGG, GMGS and AHG made the acquisition of data and review the literature. CMP analysed and supported the interpretation of the patient’s data regarding the haematological aspects. The main paper was written and designed by AdGG and GMGS. The design of the figures was done by AdGG and GMGS, AHG and CMP helped supervise the project and revised the manuscript critically for important intellectual content. All authors approved final version of the manuscript.
