Can you take apixaban for extended treatment?
However, there are alternate medication and dosing options available to patients who require indefinite anticoagulation. In appropriate patient populations, such as those without active cancer or renal insufficiency, direct-acting oral anticoagulants can be considered for extended therapy given the relative reduction in bleeding risk over vitamin K antagonists. 2 Additionally, the AMPLIFY-EXT (Apixaban After the Initial Management of Pulmonary Embolism and Deep Vein Thrombosis With First-Line Therapy–Extended Treatment) trial and EINSTEIN-CHOICE (Reduced-Dosed Rivaroxaban in the Long-Term Prevention of Recurrent Symptomatic Venous Thromboembolism) trial showed comparable rates of VTE recurrence between higher and lower doses of apixaban (5 mg vs. 2.5 mg) and rivaroxaban (20 mg vs. 10 mg), respectively, suggesting lower-dose options can also be considered. 15,16 If patients with unprovoked PE elect to discontinue anticoagulant treatment entirely, the use of aspirin 81 mg daily may be benefical in reducing major vascular events by about one-third compared with placebo, but aspirin does not reduce the recurrence of PE. 17 Thus, it is important to counsel patients that the use of oral anticoagulants versus aspirin alone reduces the risk of recurrent VTE by approximately 81-92%. 18,19
