Other Comments
Administration advice:
- For IV bolus injection only.
- Administer as soon as possible following bleeding onset or immediately before scheduled procedure.
- The manufacturer product information should be consulted.
Storage requirements:
- Prior to reconstitution: Store powder and histidine diluent between 2 and 25C (36 to 77F); do not freeze; protect from light.
- After reconstitution: Store at room temperature or refrigerated up to 3 hours; do not freeze or store in syringes.
Reconstitution/preparation techniques: The manufacturer product information should be consulted.
IV compatibility: Do not mix with other infusion solutions.
General:
- Coagulation parameters do not necessarily correlate with or predict effectiveness of this drug; use hemostasis evaluation to determine effectiveness.
- Congenital hemophilia A or B with inhibitors: Outcome decision was made for a majority of patients treated for joint or muscle bleeds within 8 doses; more doses were required for severe bleeds. A majority of patients who reported adverse experiences received more than 12 doses.
Monitoring:
- Monitor for signs or symptoms of activation of the coagulation system or thrombosis.
- Monitor and minimize the duration of any post-hemostatic dosing.
- Monitor prothrombin time (PT) and factor VII coagulant activity in factor VII deficient patients before and after administering this drug.
- Monitor for factor VII antibodies in factor VII deficient patients treated with this drug.
Patient advice:
- Inform patients to seek immediate medical attention if early signs of hypersensitivity occur (e.g., hives, urticaria, chest tightness, wheezing, hypotension, and anaphylaxis).
- Advise patients to seek immediate medical attention if signs of thrombosis occur (e.g., new onset swelling and pain in the limbs or abdomen, new onset chest pain, shortness of breath, loss of sensation or motor power, or altered consciousness or speech).
