This medication is used to prevent or control bleeding in people with little or no factor IX (due to hemophilia B, Christmas disease). Factor IX is a protein (clotting factor) in the blood that works with other clotting factors to help the blood 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 should not be used to treat other types of factor deficiencies (such as factors II, VII, VIII, X) or factor problems (such as inhibitor to factor XIII), to reverse the effects of "blood thinners" (such as warfarin), or to treat bleeding from low levels of liver-dependent clotting factors (due to liver problems).
