Humate-P

Generic name: Antihemophilic And Von Willebrand Factor Complex
Drug class: Miscellaneous coagulation modifiers

Usage of Humate-P

Antihemophilic and von Willebrand factors are naturally occurring proteins in the blood that help the blood to clot.

A lack of antihemophilic factor VIII is the cause of hemophilia A. A lack of von Willebrand factor is the cause of von Willebrand disease. Humate-P works by temporarily raising levels of factor VIII or von Willebrand factor in the blood to aid in clotting.

Humate-P is a combination medicine used to treat or prevent bleeding episodes in people with von Willebrand disease.

Humate-P is also used to treat or prevent bleeding episodes in people with hemophilia A.

Humate-P may also be used for purposes not listed in this medication guide.
