  • Antihemophilic Agent

Monitoring Parameters

Hypersensitivity reactions, heart rate and blood pressure (before and during IV administration); plasma factor VIII activity prior to and during treatment using a one-stage clotting assay to confirm adequate factor VIII levels have been achieved and maintained); development of factor VIII inhibitors using the Bethesda inhibitor assay; signs of bleeding; hemoglobin, hematocrit.

Pregnancy Considerations

Animal reproduction studies have not been conducted. Factor VIII concentrations may increase in pregnant women with coagulation disorders. Pregnant women should have clotting factors monitored, particularly at 28 and 34 weeks gestation and prior to invasive procedures. Prophylaxis may be needed if concentrations are <50 units/mL at term and treatment should continue for 3 to 5 days postpartum depending on route of delivery. The neonate may also be at an increased risk of bleeding following delivery and should be tested for the coagulation disorder (Kadir 2009; Lee 2006). Although recombinant products are generally preferred when therapy in pregnancy is needed, initial studies conducted with the pegylated product were done only in males (Konkle 2015).
