1. what d-gam is and what it is used for
D-Gam contains the active ingredient human anti-D immunoglobulin which protects against the effects of Rhesus D (Rh(D)) positive red cells in people who are Rhesus negative.
It is made from blood plasma from screened donors.
D-Gam is used during pregnancy if you are Rh(D) negative to prevent you from becoming sensitised to your baby’s red cells if your baby is Rh(D) positive.
D-Gam is also used if you are not pregnant but are Rh(D) negative and are receiving Rh(D) positive cells for any reason to prevent future complications.
D-Gam is given if you are Rh(D) negative and your baby is Rh(D) positive:
-
– as a routine preventative measure during pregnancy
-
– soon after any accident or intervention during pregnancy which might lead to bleeding across the placenta
-
– soon after an abortion when sensitisation is possible
-
– soon after giving birth
D-Gam can also be given if you are Rh(D) negative and have received blood components containing Rh(D) positive red blood cells to prevent future complications.
Your doctor, nurse or healthcare professional will tell you if it is advisable for you to have D-Gam.
2. what you need to know before you are given d-gam
Do not use D-Gam:
-
– if you are allergic (hypersensitive) to human anti-D immunoglobulin or any of the other ingredients of this medicine (listed in section 6)
-
– if you are known to have antibodies to immunoglobulin A and have had an allergic reaction
-
– if you are Rh(D) positive
Warnings and precautions
Talk to your doctor, nurse or healthcare professional before you are given D-Gam.
-
– This medicine must not be injected into the vein, since it may cause a severe reaction if given in this way. Injections must be given to you by your doctor, nurse or healthcare professional into a muscle, usually the shoulder (deltoid).
-
– For protecting Rh(D) negative women after delivery of a Rh(D) positive baby, this medicine is always given to the mother, not to the new-born baby.
-
– True allergic reactions to this product are rare, when it is injected into the muscle as directed. Even if you have had this medicine before, you could still have a reaction, for example, low blood pressure and possible shock. In the case of shock, urgent medical advice is needed (see also section 4 ‘Possible side effects’).
-
– If you are lacking immunoglobulin A (IgA deficient) you might develop antibodies to IgA, although this is not common. If you know you already have antibodies to IgA, tell your doctor, nurse or healthcare professional before your injection.
-
– If you suffer from high blood pressure, diabetes, a history of cardiovascular disease or a blood/blood related disorder, tell your doctor, nurse or healthcare professional before this medicine is injected.
-
– If you are having this medicine because you have received Rh(D) positive red cells for whatever reason, you may be given larger doses than those used in pregnancy. Your doctor will assess you for the effects of very rapid break down of the injected red cells.
-
– Immunoglobulins may increase the risk of having a blood clot, however this has not been seen with D-Gam.
-
– If you develop pain, swelling and unusual warmth of a limb, sudden shortness of breath and chest pain worsening on deep breathing, numbness or weakness on one side, difficulty with speaking or confusion, contact your doctor or nurse immediately as these symptoms may indicate that you have a blood clot.
-
– As some medicines may increase the risk of a blood clot, tell your doctor, pharmacist or nurse of all the medicines you are taking.
-
– Tell your doctor, nurse or healthcare professional if you have any blood tests. 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, nurse or healthcare professional when you last had this product injected, as misleading positive results may occur with certain tests.
-
– This medicine may not work very well in people who are overweight or very overweight. Talk to your doctor, nurse or healthcare professional for advice.
-
– Large doses (over 5 ml) will be injected into different parts of the body.
Viral Safety
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 viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis A (HAV) and parvovirus B19 viruses.
Immunoglobulins have not been associated with HAV 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 D-Gam the name and batch number of the medicine are recorded in order to maintain a record of the batches used.
Other medicines and D-Gam
Tell your doctor, nurse or healthcare professional if you are taking, have recently taken or might take any other medicines.
Vaccinations
Tell your doctor, nurse or healthcare professional 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 3 weeks before D-Gam or not until 3 months after. D-Gam is unlikely to contain an antibody to yellow fever; so this vaccine can be given whenever needed.

3. How you are given D-Gam
This medicine will be given to you by your doctor, nurse or healthcare professional into a muscle, usually the shoulder (deltoid). Your doctor, nurse or healthcare professional will decide how much D-Gam you should receive.
Injection should be as soon as possible after an accident or intervention during pregnancy and after delivery (ideally within 72 hours).
No other medicines or fluids should be added to this product as their effects on the product have not been established.
If you receive more D-Gam than you should
If you are given more D-Gam than recommended, your doctor, nurse or healthcare professional may carry out some blood tests. It is not known what effects an overdose would have.
If you have any further questions on the use of this medicine, ask your doctor, nurse or healthcare professional.
4. possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
If you feel unwell, tell your doctor immediately. Side effects may occur even if you have previously received human immunoglobulins and tolerated them well.
