Important Risk Information for RIXUBIS [Coagulation Factor IX (Recombinant)]

Please read below for Indications and Detailed Important Risk Information for RIXUBIS. See full Prescribing Information.

Indications for RIXUBIS® [Coagulation Factor IX (Recombinant)]

RIXUBIS® [Coagulation Factor IX (Recombinant)] is an antihemophilic factor indicated in adults and children with hemophilia B for control and prevention of bleeding episodes, perioperative management, and routine prophylaxis.

RIXUBIS is not indicated for induction of immune tolerance in patients with hemophilia B.

Detailed Important Risk Information for RIXUBIS® [Coagulation Factor IX (Recombinant)]


RIXUBIS is contraindicated in patients who have:

  • Known hypersensitivity to RIXUBIS or its excipients including hamster protein
  • Disseminated Intravascular Coagulation (DIC)
  • Signs of fibrinolysis


Hypersensitivity Reactions
Hypersensitivity reactions, including anaphylaxis, may occur. Should symptoms occur, discontinue RIXUBIS and administer appropriate treatment. Patients may also develop hypersensitivity to hamster (CHO) protein, which is present in trace amounts in the product.

Development of neutralizing antibodies (inhibitors) to RIXUBIS may occur. Regularly evaluate patients for the development of factor IX inhibitors by appropriate clinical observations and laboratory tests. If expected factor IX plasma activity levels are not attained, or if bleeding is not controlled with an expected dose, perform an assay that measures factor IX inhibitor concentration. Patients with factor IX inhibitors are at an increased risk of severe hypersensitivity reactions or anaphylaxis if re-exposed to RIXUBIS.

Nephrotic Syndrome
Nephrotic syndrome has been reported following attempted immune tolerance induction with factor IX products in hemophilia B patients that have factor IX inhibitors. The safety and efficacy of using RIXUBIS for immune tolerance induction have not been established.

Thromboembolic Complications
The use of factor IX containing products has been associated with the development of thromboembolic complications. Monitor patients for early signs of thromboembolic and consumptive coagulopathy, when administering RIXUBIS to patients with liver disease, with signs of fibrinolysis, peri- and post-operatively, or at risk for thromboembolic events or DIC.

Common adverse reactions observed in >1% of subjects in clinical studies were: dysgeusia, pain in extremity, and positive test for furin antibody.
