TY - JOUR T1 - Superwarfarin poisoning: challenges still remain JF - BMJ Case Reports JO - BMJ Case Reports DO - 10.1136/bcr-2021-248385 VL - 15 IS - 5 SP - e248385 AU - Ariadna de Genover Gil AU - Gabriel Manuel Gonzalez Suarez AU - Carla Moret Puig AU - Abelardo Hurtado Ganoza Y1 - 2022/05/01 UR - http://casereports.bmj.com/content/15/5/e248385.abstract N2 - 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.
