Descriptions
Antihemophilic factor (AHF) injection is used to treat, control, prevent, and decrease the frequency of bleeding episodes, and prevent bleeding during surgery in patients with hemophilia A (congenital Factor VIII deficiency).
Antihemophilic factor (AHF) is a protein that is produced naturally in the body. It helps the blood form clots to stop bleeding and prevents bleeding problems from happening as often.
Hemophilia A, also called classical hemophilia, is a condition where the body does not make enough AHF. If you do not have enough AHF and you become injured, your blood will not form clots properly. You might bleed into and damage your muscles and joints. AHF injection is given to increase the levels of AHF in the blood.
There are several different types of AHF. They are made from human blood or artificially by a man-made process (recombinant). AHF made from human blood has been treated and is not likely to contain harmful viruses, such as hepatitis B, hepatitis C, or human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS). The man-made AHF products do not contain these viruses.
This medicine is available only with your doctor’s prescription.
