Generic Name: antihemophilic factor/von willebrand factor (human) (AN-tee-hee-moe-FIL-ik FAK-tor/von WILL-a-brand FAK-tor)
Brand Name: Alphanate
Alphanate is used for:
Preventing and controlling bleeding in adult patients with hemophilia A. It is also used to control certain types of bleeding episodes (eg, due to injury or surgery) in patients with von Willebrand disease.
Alphanate is a human clotting factor complex prepared from pooled human plasma. It works by increasing the amount of clotting factor VIII and von Willebrand factor in the blood. This helps the blood to clot properly, which helps to stop bleeding.

Contact your doctor or health care provider right away if any of these apply to you.
