Abstract
Background: Warfarin, a coumarin derivate which is the first
anticoagulant used is a vitamin K antagonist mainly used as an
anticoagulant. Unintentional toxicity is due to dosing, diet plan, drug
interaction and liver disease. Not only these factors but also genetic
polymorphisms can also affect the toxicity. The treatment or
management of patients who had warfarin toxicity can vary based on
their number of clinical symptoms or factors. Case Presentation: A
79-year-old male patient with 68 kg and 163 cm height was admitted in
tertiary care hospital, with chief complaints of bleeding tendency,
history of fall on the day before hospitalisation and history of blood in
stool. Diagnosed as warfarin toxicity (Drug induced lower Gastric bleeding), Diabetes
mellitus II, Chronic obstructive pulmonary disease, Atrial fibrillation, and Chronic kidney
disease using physical and laboratory examination. Warfarin was stopped and administered
vitamin K along with other regular medicines. Also converted the diet from normal to
diabetic diet. The patient treated with fresh frozen plasma transfusion, Vitamin K, Insulin,
Oral antihyperglycemic agent, antiplatelets, statins, diuretics and other supportive measures.
Cardiology and nephrology management done as per advice. Discussion: The patients who
are on warfarin need for a better communication between patient and health care providers by
means of providing counselling regarding all aspects of medications as well as lifestyle
modifications and by giving patient information leaflets.
