What Is XYNTHA?

XYNTHA does not contain von Willebrand factor and, therefore, is not indicated in von Willebrand's disease.

Important Safety Information for XYNTHA

• Allergic reactions are possible with XYNTHA. Signs of an allergic reaction may include hives, rash with itching, chest tightness, difficulty breathing, faintness, or fast heartbeat. XYNTHA contains trace amounts of hamster protein. You may develop an allergic reaction to these proteins. Tell your doctor if you have had an allergic reaction to hamster protein.
• Call your doctor right away if bleeding is not controlled after using your factor VIII replacement therapy; this may be a sign of an inhibitor. Inhibitors have been observed in patients receiving factor VIII products, including XYNTHA.
