This medication is used to treat and control bleeding episodes in people with little or no factor IX (due to hemophilia B, Christmas disease). Factor IX is a protein normally found in the blood that helps the blood to thicken (clot) and stop bleeding. People with little or no factor IX are at risk for bleeding longer after an injury/surgery or bleeding suddenly (often in the joints/muscle) without an obvious cause. This medication contains a man-made form of factor IX.
