1 What is Alphanate?

Brand: Alphanate, Humate-P, Wilate

Generic: Antihemophilic Factor VIII and Von Willebrand Factor (Intravenous Route)

Alphanate is a combination medication used to treat serious bleeding episodes in patients with a bleeding disorder called Von Willebrand disease (VWD). The bleeding episode may be related to an injury or surgical procedure. This medication may also be used to stop bleeding in patients with Hemophilia A.

Antihemophilic factor VIII and Von Willebrand factor are normally produced by the body. They help blood to clot when an injury occurs. Patients with VWD or hemophilia A do not make enough of these substances to prevent bleeding, so this product is given to increase these levels in the blood.

This medication is only available with your doctor’s prescription. This medication is available in the powder for solution form.
