How does BENEFIX work?

How do I take BENEFIX?
BeneFIX is given as an injection into the veins (intravenous or IV).

- BeneFix: The typical dose is 100 international units (IU)/kg of body weight given IV once weekly

- Rebinyn: The typical dose is 40 IU/kg IV once weekly
On-demand treatment of bleeding, including during surgery: Your provider will calculate your dose based on things like body weight, how serious your bleed is, where the bleed is, the desired level of factor IX in your body, and the brand of factor IX recombinant you’re receiving.
