Andexxa comes in powder form which is then reconstituted to be injected into a vein by a healthcare professional.
The recommended Andexxa dosage is based on the factor Xa inhibitor taken, its dose, and the time since the last factor Xa inhibitor dose.
Two dosage regimens are recommended.
Patients taking ≤10 mg of rivaroxaban or ≤5 mg of apixaban per dose should receive the low-dose regimen, a 400-mg IV bolus dose of andexanet alfa, followed by a 4 mg/minute continuous infusion for up to 120 minutes.
Patients taking >10 mg of rivaroxaban or >5 mg of apixaban per dose should receive the high-dose regimen, an 800-mg IV bolus dose of andexanet alfa, followed by an 8 mg/minute continuous infusion for up to 120 minutes if their last dose was <8 hours before starting andexanet alfa; if the last dose was ≥8 hours before starting andexanet alfa, the low-dose regimen should be used. If the dose and/or timing since the last dose of the factor Xa inhibitor is unknown, the high-dose regimen should be used. The optimal dosage of andexanet alfa for patients taking other factor Xa inhibitors has not been established.
If Andexxa is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.
Unopened vials should be stored refrigerated at 2°C to 8°C (36°F to 46°F).
