This medication is used to control and prevent bleeding episodes in people with low levels of factor VIII (hemophilia A). It is also used in these patients before surgery to prevent bleeding. People with low factor VIII levels are at risk for bleeding longer after an injury/surgery and for bleeding inside the body (especially into the joints and muscles). This product contains a man-made form of factor VIII, also called antihemophilic factor. This product is used to temporarily replace the missing factor VIII, a protein (clotting factor) that is normally in the blood, so that the blood can clot and the bleeding can stop.
This medication should not be used to treat von Willebrand disease.
