Factor IX (nine) is a naturally occurring protein in the blood that helps blood to clot. A
lack of clotting factors can cause uncontrolled bleeding, as the blood is unable to clot properly.
Factor IX complex is a combination of four different clotting factors and other proteins.
This medication works by temporarily raising levels of these clotting factors in the blood to aid in
clotting.
Factor IX complex is used to
treat or prevent
bleeding episodes in
people with hemophilia B. It is also used to control bleeding related to surgery or dentistry in
people with hemophilia B.
Factor IX may also be used for other purposes not listed in this medication guide.
