In order to prevent hepatitis B: Prevention of hepatitis B in case of accidental exposure in non-immunised subjects: at least 500 IU (International Units), depending on the intensity of exposure, as soon as possible after exposure, and preferably within 24 - 72 hours.

Serious allergic reactions are rare. Rarely, the human anti-hepatitis B immunoglobulins can induce a sudden fall in blood pressure with disorder of breathing, faints, sometimes fever and skin reactions (anaphylactic reaction).

When medicines are made from human blood or plasma, certain measures are put in place to prevent infections being passed on to patients. These include: A careful selection of blood and plasma donors to make sure that those at risk of carrying infections are excluded; The testing of the donations to ensure that there are no infective agents and/or viruses; The inclusion, during manufacturing process of steps capable of inactivating or removing viruses. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging infectious agents or other types of infections.The measures taken are considered effective for viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and for hepatitis A virus (HAV). The measures taken may be of limited value against viruses such as parvovirus B19. Immunoglobulins have not been associated with hepatitis A or parvovirus B19 infections possibly because the antibodies against these infections, which are contained in the product, are protective. It is strongly recommended that every time you receive a dose of Hepatitis b immune globulin the name and batch number of the product are recorded in order to maintain a record of the batches used.
