What is the most important information I should know about Factor Viii?

· Some forms of Factor Viii are made from human plasma (part of the blood) and may contain infectious agents (e.g., viruses) that can cause disease. Although Factor Viii is screened, tested, and treated to reduce the possibility that it carries an infectious agent, it can still potentially transmit disease. Discuss with your doctor the risks and benefits of using Factor Viii from human sources.

· Some viruses, such as parovovirus B19 and hepatitis A, may be more difficult to identify or remove from Factor Viii. Parovovirus B19 may more seriously affect pregnant women and those with poor immune systems. Symptoms of parovovirus B19 infection include fever, chills, runny nose, and drowsiness followed about 2 weeks later by a rash and joint pain. Symptoms of hepatitis A may include several days to weeks of poor appetite, tiredness, and low-grade fever followed by nausea, vomiting, and pain in the belly. Dark-colored urine and yellowing of the skin or whites of the eyes may also occur. Contact your doctor if you develop any of these symptoms after treatment with Factor Viii.
