Coagulation factor viia (Intravenous)

Factor VIIa is used to treat and prevent bleeding episodes in patients with Hemophilia A or B who have developed antibodies against other clotting proteins (for example, Factor VIII or Factor IX) that help stop bleeding. It is also used to treat or prevent bleeding in patients with acquired hemophilia, congenital Factor VII deficiency, or Glanzmann's thrombasthenia (a bleeding disorder caused by a blood abnormality) that has been treated with platelet transfusions but did not respond well.

Factor VIIa is a man-made protein created to imitate the naturally occurring activated factor VII (factor VIIa) in the body. It is used to stop bleeding from injuries in patients with hemophilia by aiding the blood to clot.

Factor VIIa must be given only by or under the direct supervision of your doctor.
