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 during manufacture.
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 prescription.
Speak to your doctor or your midwife and do not use D-Gam®:
• If you think you could be allergic (hypersensitive) to the active substance or to any of 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 be stopped immediately.
• True allergic reactions to this product are rare, when it is injected intramuscularly as directed. In the case of shock, urgent medical advice is needed.
• Large doses (over 5 mL) will be injected into different parts of the body.
• 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.
Driving and using machines
This medicine has been widely used for many years in pregnant women without any harmful effects. There are no known effects on the ability to drive or operate machinery after injection of this product.
D-Gam will be administered to you by your doctor or your midwife by injection into a large muscle, ideally of your upper arm just below the shoulder (deltoid).
Injection should be as soon as it is convenient after an accident or intervention during pregnancy and after delivery (ideally within 72 hours). Injection of this medicine, should be as close to the time of the incident as possible.

Following an Accident or Intervention During Pregnancy:
Up to 20 weeks, the recommended dose is 250 IU;

Your doctor or midwife will tell you if it is advisable for you to have this medicine, how much and when.

• Not everybody gets side effects, but the following have been reported after injection:
chest pain, shortness of breath, dizziness, swelling of the face,
headache, feeling cold, shaking, feeling or being sick,
joint pains, coating of the tongue, mouth ulcers
As with all intramuscular injections, there may be some short-term discomfort at the site of injection. Very rarely, a hardened area may develop where the injection was given.

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.
