Hepatitis B immunoglobulin is used to prevent infections of the liver known as hepatitis B (contagious liver infection caused by a virus from contaminated blood and body fluids).
This medicine helps prevent infections from developing in a person who had been exposed to hepatitis B virus (e.g. through skin pricks, cuts, or sexual contact).
It may be used for those who have not been vaccinated, have not responded to hepatitis B vaccination, or if you are having kidney dialysis while waiting for vaccination to be fully effective.
Hepatitis B immunoglobulin may also be used in babies whose mother has a hepatitis B infection.
Hepatitis B immunoglobulin injection is to be given intramuscularly (into the muscle).
Your doctor or nurse will administer the injection for you.
