What is Hyperhep B (Hepatitis B Immune Globulin)?
Hepatitis B immune globulin is made from human plasma containing proteins that protect against the type B form of hepatitis (inflammation of the liver).
Hepatitis B immune globulin is used to prevent hepatitis B in people receiving a liver transplant, and in babies born to mothers infected with hepatitis B. It is also used to prevent hepatitis B in people who have been exposed to contaminated blood products, or through household or sexual contact with an infected person.
Hepatitis B immune globulin is not a vaccine. Therefore it will not provide long-term protection from hepatitis B. For long-term protection you must receive a hepatitis B vaccine such as Engerix-B, Recombivax HB, or Twinrix.
Hepatitis B immune globulin may also be used for other purposes not listed in this medication guide.
