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.<\/jats:p>","DOI":"10.1136\/bcr-2021-248385","type":"journal-article","created":{"date-parts":[[2022,5,18]],"date-time":"2022-05-18T11:40:31Z","timestamp":1652874031000},"page":"e248385","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Superwarfarin poisoning: challenges still remain"],"prefix":"10.1136","volume":"15","author":[{"given":"Ariadna","family":"de Genover Gil","sequence":"first","affiliation":[{"name":"Internal Medicine, Doctor Josep Trueta University Hospital of Girona, Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel Manuel","family":"Gonzalez Suarez","sequence":"additional","affiliation":[{"name":"Nephrology, Doctor Josep Trueta University Hospital of Girona, Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Moret Puig","sequence":"additional","affiliation":[{"name":"Haematology, Hospital de la Santa Creu i Sant Pau, Barcelona, Catalunya, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abelardo","family":"Hurtado Ganoza","sequence":"additional","affiliation":[{"name":"Internal Medicine, Doctor Josep Trueta University Hospital of Girona, Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,5,18]]},"reference":[{"key":"2025082703130168000_15.5.e248385.1","unstructured":"Brunton L , Chabner BA , Knollman B .
