Factor VIIa, Recombinant

Recombinant factor VIIa is a blood clotting factor that is used in hemophiliac patients, particularly those who are currently bleeding due to trauma. Hemophilia is a rare but serious blood disease in which a person’s blood does not clot. Even minor cuts and injuries can cause the hemophiliac person to bleed for hours. Patients receive recombinant factor VIIa via injections. The injection is repeated several times; dosing frequency depends on how severe the person’s condition is.
