Precautions
If you were recently diagnosed with hemophilia B, you should receive hepatitis A and hepatitis B vaccines to reduce even further your risk of getting hepatitis A or hepatitis B from factor IX products.
After a while, your body may build up a defense (antibody) against this medicine. Tell your doctor if this medicine seems to be less effective than usual.
It is recommended that you carry identification stating that you have hemophilia A or hemophilia B. If you have any questions about what kind of identification to carry, check with your health care professional.
