Oral anticoagulantion is used for the prevention and treatment of thromboembolism in patients with nonvalvular atrial fibrillation (NVAF), venous thromboembolism (VTE), mechanical heart valves, and other hypercoagulable states. In the past, warfarin was the predominant oral anticoagulant. Recently, direct oral anticoagulants (DOACs) have replaced warfarin as the preferred agents for the most common indications for oral anticoagulation: NVAF and VTE. The complication of anticoagulants is bleeding. Treatment including withholding the anticoagulant or administering medications to counteract the excessive anticoagulation and monitoring for further bleeding and/or the response to therapy can be done in the OU.
