Antihemophilic factor is a naturally occurring protein in the blood that helps blood to clot.
A lack of antihemophilic factor VIII is the cause of hemophilia A. A lack of an
antihemophilic factor called von Willebrand factor is the cause of von Willebrand disease.
This medication works by temporarily raising levels of factor VIII or von Willebrand
factor in the blood to aid in clotting.
Antihemophilic factor-von Willebrand factor complex is used to
treat or prevent
bleeding episodes in adults with hemophilia A. It is also used to
treat
injury-related bleeding episodes in adults and children with von Willebrand disease.
Antihemophilic factor-von Willebrand factor complex may also be used for other
purposes not listed in this medication guide.
