What is antihemophilic factor-von Willebrand factor complex (Alphanate, Humate-P)?
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.
