Interaction Effect
An increased risk of bleeding
Interaction Summary
Coadministration of apixaban, a factor Xa inhibitor, with another anticoagulant increases the risk of bleeding. In studies of pharmacodynamic drug interactions with apixaban, a 50% to 60% increase in anti-factor Xa activity was observed with concomitant administration of apixaban and enoxaparin. Discontinue apixaban if active pathological bleeding occurs. An agent to reverse the anti-factor Xa activity of apixaban is available. The pharmacodynamic effect of apixaban can be expected to persist for at least 24 hours after the last dose[1]. If concomitant use of apixaban and another anticoagulant is necessary, monitor the patient closely and use with caution.

Apixaban Overview
-
Apixaban is used help prevent strokes or blood clots in people who have atrial fibrillation (a condition in which the heart beats irregularly, increasing the chance of clots forming in the body and possibly causing strokes) that is not caused by heart valve disease. Apixaban is also used to prevent deep vein thrombosis (DVT; a blood clot, usually in the leg) and pulmonary embolism (PE; a blood clot in the lung) in people who are having hip replacement or knee replacement surgery. Apixaban is also used to treat DVT and PE and may be continued to prevent DVT and PE from happening again after the initial treatment is completed. Apixaban is in a class of medications called factor Xa inhibitors. It works by blocking the action of a certain natural substance that helps blood clots to form.
