HepaGam B is a brand name for an hepatitis B immunoglobulin product used to prevent hepatitis B virus infection in people who have been exposed to the virus. It contains antibodies to the hepatitis B virus and is obtained from pooled human plasma. HepaGam B is not a vaccine, which means it doesn't provide long-term protection against this virus. It is administered by intravenous injection given by a healthcare professional at a hospital or clinic. For people receiving liver transplants, HepaGam B may be given every day for a week following the transplant, then once every two weeks and gradually down to once a month. For people who have been exposed to hepatitis B, HepaGam B may be given as soon as possible after exposure, followed by a second injection 24 hours after the first. Babies who are born to mothers with hepatitis B should be given HepaGam B within 12 hours of being born.
