Hepatitis B immunoglobulin (HBIG) is a solution of
antibodies that are able to attach to the
hepatitis B viruses and cause them to be destroyed.
An injection of HBIG may help prevent HBV infection if it is given
within 14 days of exposure to the virus when you:
Have not been immunized against HBV but have come
in contact with the blood or body fluids (semen or
vaginal fluids, including menstrual blood) of someone who has hepatitis
Are being immunized against HBV but have not yet received all
three shots in the vaccination series and are exposed to the virus. In most
cases, HBIG will prevent infection until the vaccine takes effect.
A dose of HBIG also may be given to babies born to women who have hepatitis B.
HBIG is safe for women who are pregnant or breastfeeding.
