Bleeding with anticoagulation

The purpose of this page will be to focus on toxicity of anticoagulation, i.e., bleeding. It will be further organized over time.

Apixaban (Eliquis) reversal

Factor Xa, recombinant, inactivated-zhzo (Andexxa)

• Factor Xa, recombinant, inactivated-zhzo (Andexxa) as follows:
  • Apixaban dose up to 5 mg: 400 mg IV bolus at a target rate of 30 mg/min then 480 mg IV infusion at a rate of 4 mg/min for 2 hours
  • Apixaban dose greater than 5mg or unknown but at least 8 hours since last administration: 400 mg IV bolus at a target rate of 30 mg/min then 480 mg IV infusion at a rate of 4 mg/min for 2 hours
