Rebinyn (Intravenous)

Coagulation factor IX (recombinant), glycoPEGylated injection is used to manage bleeding episodes and prevent bleeding during surgery for patients with hemophilia B (congenital Factor IX deficiency).

Factor IX is a protein that the body makes naturally. This medicine is a synthetic version of that protein, created to mimic the natural factor IX found in the body. It helps stop bleeding by aiding blood clotting in patients with hemophilia B.
