Some human blood products have transmitted viruses to people who have received them. This medicine is made from donated human blood that has been tested and treated for viruses to keep from spreading infections. The risk of getting a virus from medicines made of human blood has been greatly reduced in recent years. This is the result of required testing of human donors for certain viruses, and testing during manufacture of these medicines. Although the risk is low, talk with your doctor if you have concerns.
Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of certain medical tests.
