What is Andexxa, and what does it treat?
Andexxa (andexanet alfa) is a medication used to reverse the blood-thinning effects of factor Xa inhibitors in certain serious bleeding situations. It is given as a treatment when patients on drugs such as apixaban or rivaroxaban have life-threatening bleeding and need urgent reversal of anticoagulation. [1]
Which anticoagulants does Andexxa reverse?
Andexxa is designed to reverse the activity of factor Xa inhibitors. This includes commonly used drugs like apixaban (Eliquis) and rivaroxaban (Xarelto). [1]
How is Andexxa given?
Andexxa is administered through the intravenous route as part of an anticoagulation reversal regimen. [1]
What are the main risks or side effects people ask about?
A common safety concern discussed with Andexxa is the risk of thrombosis (blood clots) and thromboembolic events, since reversing anticoagulation can restore clotting ability. Other adverse events can occur, but the key patient concern is clot risk after reversal. [1]
Can Andexxa be used for any type of bleeding?
Andexxa is indicated for serious (including life-threatening) bleeding in patients taking factor Xa inhibitors, rather than for mild or non-emergent bleeding. The clinical context determines whether reversal is appropriate. [1]
How does Andexxa compare with other reversal options (e.g., for warfarin)?
Andexxa is specific to factor Xa inhibitors. Reversal strategies differ by anticoagulant class—for example, warfarin reversal uses other agents (not Andexxa). The choice depends on which blood thinner the patient took. [1]
Who makes Andexxa?
Andexxa is marketed by Portola Pharmaceuticals in the United States. [1]
