What is von Willebrand factor?

Von Willebrand factor is a naturally occurring protein in the blood that helps blood to clot. People with an inherited blood-clotting disorder called von Willebrand disease do not have enough of this protein in their blood. A lack of von Willebrand factor can cause uncontrolled bleeding.

Von Willebrand factor is used to control bleeding episodes in adults with von Willebrand disease.

Von Willebrand factor may also be used for purposes not listed in this medication guide.
