1. WHAT D-GAM® IS AND WHAT IT IS USED FOR
The product D-Gam is a solution for injection containing an increased amount of
anti-D gammaglobulin (antibodies which can protect against certain conditions). It is
made from blood plasma from screened donors from the USA and virally-inactivated
D-Gam also contains sodium chloride at the same strength as is normally found in your
body, glycine and sodium acetate with a small quantity of sodium hydroxide to control
acidity/alkalinity during manufacture. D-Gam is available in four dose sizes of 250 IU,
500 IU, 1,500 IU and 2,500 IU (IU means International Unit of anti-D). D-Gam is used to
prevent RhD negative women of child-bearing age, becoming sensitised (reactive) to RhD
positive red blood cells, to protect a RhD positive baby’s red blood cells either during the
current pregnancy or, more particularly, in future pregnancies.
It should be used:
• Soon after giving birth to a baby whose red blood cells are RhD positive, irrespective of
the ABO blood group of the mother;
• Soon after an abortion when sensitisation is possible;
• Soon after any accident or intervention during pregnancy which might lead to bleeding
across the placenta;
• As a routine preventative measure during pregnancy;
• Soon after blood components containing RhD positive red blood cells have been given,
for any reason, even when you are not pregnant.
Your doctor or your midwife will tell you if it is advisable for you to have D-Gam.
The product is for injection into muscles, and is only available on a doctor’s

the other ingredients of D-Gam (see Section 6 for a list of these).
• If you suffer from any blood disorders, which interfere with clotting.
Take special care with D-Gam®
• This product must not be injected intravenously (into veins), since it may cause a
severe reaction if given in this way. Injections must be intramuscular.
• If you start to feel unwell when this medicine is being injected, then the injection must

• This medicine is not for injection into the newborn baby.
Using other medicines
• Please tell your doctor or your midwife of any vaccinations you have recently had or are
about to have.
• Besides anti-D, D-Gam provides you with a range of antibodies. These antibodies will
interfere with the response to some vaccines, especially MMR (measles, mumps and
rubella) and varicella (chickenpox) vaccines. Such vaccinations should be given at least
three weeks before D-Gam or not until three months after. D-Gam is unlikely to contain
an antibody to yellow fever; so this vaccine can be given whenever needed.
• This product will raise the level of various antibodies in your blood for several weeks.
If you require a blood test during this period, tell your doctor when you last had this
product injected, as misleading positive results may occur with certain tests.

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: – careful
selection of blood and plasma donors to make sure those at risk of carrying infections
are excluded, – the testing of each donation and pools of plasma for signs of virus/
infections, – the inclusion of steps in the processing of the blood or plasma that can
inactivate or remove 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 viruses or other types
of infections. The measures taken are considered effective for enveloped viruses such as
human immunodeﬁciency virus (HIV), hepatitis B virus and hepatitis C virus, and for the
nonenveloped hepatitis A and parvovirus B19 viruses. 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.
If any of the side effects gets serious, or if you notice any side effects not listed in this
leaﬂet, please tell your doctor.
