AbstractThe management of patients with supra-therapeutic INR in a common clinical problem. The risk of bleeding is influenced by the intensity, variability and duration of anticoagulation, patient age, presence of co-morbidities and concomitant drug therapy. For the asymptomatic patient, warfarin discontinuation is all that is usually required but for individuals at high risk of bleeding and those with INR > 10, oral vitamin K administration is recommended. In the presence of major bleeding, treatment with intravenous vitamin K and prothrombin complex concentrate is the most effective therapy.
