Description

Antihemophilic (an-tee-hee-moe-FIL-ik) factor (AHF) is a protein produced naturally in the body. It helps the blood form clots to stop bleeding.

Hemophilia A, also called classical hemophilia, is a condition in which the body does not make enough AHF. If you do not have enough AHF and you become injured, your blood will not form clots as it should, and you may bleed into and damage your muscles and joints. One type of AHF is used to treat another condition called von Willebrand disease, in which there is a risk of bleeding. AHF also may be used for other conditions as determined by your doctor.

The AHF that your doctor will give you is obtained naturally from human or pig blood or artificially by a man-made process.

AHF obtained from human blood has been treated. It is not likely to contain harmful viruses such as hepatitis B virus; hepatitis C virus (non-A, non-B hepatitis); or human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS). The man-made and pork AHF products do not contain these viruses.

AHF is available only with your doctor"s prescription, in the following dosage form:

• Parenteral
• Injection (U.S. and Canada)
