Lab Test Considerations:
Measure INR prior to therapy close to time of dosing; base dose on INR value and patient body weight. Monitor INR and clinical response during and after infusion.
Administer Vitamin K concurrently to maintain Vitamin K-dependent clotting factor levels once effects of prothrombin complex concentrate human have diminished.
Intermittent Infusion: Follow reconstitution instructions in provided for Mix2Vial transfer set. Reconstitute with 20 mL of diluent provided in kit. Do not use beyond expiration date. Solution is colorless and clear to opalescent; do not use solutions that are discolored, cloudy or contain particulate matter. Do not allow blood to enter syringe during infusion, may cause fibrin clot formation. Concentration: Final concentration in Factor IX units will range from 20–31 units/mL when reconstituted. Actual potency is listed on carton. If patient is to receive multiple vials, may pool contents; use a separate unused Mix2Vial transfer set for each vial. Administration should begin promptly or within 4 hrs of reconstitution. Record lot number of product in patient's chart when administered. Store between 2–25° C; do not freeze. For single use only; discard unused portions.
Rate: 0.12 mL/kg/min up to maximum rate of 8.4 mL/kg/min
