A solution for injection.


4.1    Therapeutic indications

Prevention of RhD immunisation in RhD negative women:

i.    Pregnancy/delivery of a RhD positive baby.

ii.    Abortion/threatened abortion, ectopic pregnancy or hydatidiform mole.

iii.    After ante-partum haemorrhage (APH), amniocentesis, chorionic biopsy or obstetric manipulative procedure e.g. external version, or abdominal trauma, which may cause transplacental haemorrhage (TPH).

Treatment of RhD negative patients after transfusions of RhD positive blood or other products containing RhD positive red blood cells (e.g. platelets).

4.2 Posology and method of administration


a)    Post-Natal Dosage:

The recommended dose is 500 IU.

For postnatal use, the product should be administered as soon as possible within 72 hours of delivery.

If a large fetomaternal haemorrhage is suspected, its extent should be determined by a suitable method and additional doses of anti-D should be administered as indicated.

b)    Ante-Natal Prophylaxis:

500 IU given at both 28 and 34 weeks of gestation or a single dose of 1,500 IU at 28 weeks of gestation.

c)    Following a Potentially Sensitising    Event During Pregnancy:

D-GAM ® should be administered as soon as possible and no later than 72 hours after the event.

Up to 20 weeks gestation: recommended dose is 250 IU per incident.

After 20 weeks gestation: recommended dose is 500 IU per incident. A test for the size of the FMH should be performed when anti-D is given after 20 weeks and additional doses of anti-D should be administered as indicated.

d)    Prevention of Immunisation in RhD Negative Patients Given Blood Components Containing RhD Positive Cells:

Recommended doses: 125 IU per mL of transfused RhD positive red cells; 250 IU per three adult doses of platelets.

Method of administration

For intramuscular use (preferably into the deltoid muscle).

D-GAM ® vials are for single use only.

In the case of haemorrhagic disorders, where intramuscular injections are contraindicated, Anti-D immunoglobulin may be administered subcutaneously. Careful manual pressure with a compress should be applied to the site after injection.

If large total doses (>5 mL) are required, it is advisable to administer them in divided doses at different sites.

4.3 Contraindications

Hypersensitivity to any of the components.

4.4 Special warnings and precautions for use

Do not administer this product intravenously (risk of shock).

In the case of post-partum use, the product is intended for maternal administration. It should not be given to the newborn infant.

The product is not intended for use in RhD positive individuals.

Patients should be observed for at least 20 minutes after administration.

If symptoms of allergic or anaphylactic type reactions occur, immediate discontinuation of the administration is required.

True hypersensitivity reactions are rare but allergic type responses to Anti-D immunoglobulin may occur. Patients should be informed of the early signs of hypersensitivity reactions including hives, generalised urticaria, tightness of the chest, wheezing, hypotension and anaphylaxis. The treatment required depends on the nature and severity of the side effect. In case of shock, the current medical standards for shock treatment should be observed.

D-GAM ® contains a small quantity of IgA. Although anti-D immunoglobulin has been used successfully to treat selected IgA deficient individuals, the attending physician must weigh the benefit against the potential risks of hypersensitivity reactions. Individuals deficient in IgA have a potential for development of IgA antibodies and anaphylactic reactions after administration of blood components containing IgA.

Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation/removal of viruses.

Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot be totally excluded. This also applies to unknown or emerging viruses and other pathogens.

The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) and for the non-enveloped hepatitis A and parvovirus B19 viruses.

In the interest of patients, it is recommended that, whenever possible, every time that D-GAM ® is administered to them, the name and batch number of the product is registered.

4.5 Interaction with other medicinal products and other forms of interaction

Active immunisation with live virus vaccines (e.g. measles, mumps or rubella) should be postponed until 3 months after the administration of Anti-D immunoglobulin, as the efficacy of the live virus vaccine may be impaired. If Anti-D immunoglobulin needs to be administered within 2-4 weeks of a live virus vaccination, then the efficacy of such a vaccination may be impaired.

After injection of immunoglobulin, the transitory rise of the various passively transferred antibodies in the patient’s blood may result in misleading positive results in serological testing.

The results of blood typing and antibody testing, including the Coombs’ or antiglobulin test, are significantly affected by the administration of anti-D immunoglobulin.

4.6 Pregnancy and lactation

This medicinal product is used in pregnancy.

4.7 Effects on ability to drive and use machines

No effects on ability to drive and use machines have been observed.

4.8 Undesirable effects

Local pain and tenderness can be observed at the injection site; this can be prevented by dividing larger doses over several injection sites.

The following side effects are known to be associated with Anti-D (the incidence has not been quantified): Occasionally fever, malaise, headache, cutaneous reactions and chills occur. In rare cases: nausea, vomiting, hypotension, tachycardia and allergic or anaphylactic type reactions, including dyspnoea and shock, are reported, even when the patient has shown no hypersensitivity to previous administration.

For information on viral safety see 4.4.

4.9 Overdose

No data are available on overdosage. RhD negative patients who are given RhD positive blood or other products containing RhD positive red blood cells and receive anti-D immunoglobulin should be monitored clinically and by biological parameters, because of the risk of haemolytic reaction.

In other RhD negative individuals, overdosage should not lead to more frequent or more severe undesirable effects than the normal dose.

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: immune sera and immunoglobulins: Anti-D (Rh) immunoglobulin. ATC code: J06B B01.

Anti-D immunoglobulin contains specific antibodies (IgG) against the RhD antigen of human erythrocytes.

5.2 Pharmacokinetic properties

Measurable levels of antibodies are obtained approximately 8 hours after intramuscular injection. Peak serum levels are usually achieved 2 to 4 days later.

The half-life in the circulation of individuals with normal IgG levels is 3 to 5 weeks.

IgG and IgG-complexes are broken down in cells of the reticuloendothelial system.

5.3 Preclinical safety data

D-GAM ® is a preparation of human plasma proteins, so safety testing in animals is not particularly relevant to the safety of use in man. Acute toxicity studies in rat and mouse showed species specific reactions, which bear no relevance to administration in humans.

Repeated dose safety testing is impracticable due to the induction of and interference with antibodies to human protein. Clinical experience provides no sign of tumourigenic and mutagenic effects.
