What is Xyntha?
Xyntha contains recombinant antihemophilic factor. Antihemophilic factor is a naturally occurring protein in the blood that helps blood to clot. A lack of antihemophilic factor VIII is the cause of hemophilia A.
Xyntha works by temporarily raising levels of factor VIII in the blood to aid in clotting.
Xyntha is used to treat or prevent bleeding episodes in adults and children with hemophilia A. It is also used to control bleeding related to surgery or dentistry in a person with hemophilia, and to prevent joint damage in people age 16 or older with severe hemophilia A and no prior joint damage.
Xyntha is not for use in people with von Willebrand disease.
