Drugs List
Therapeutic Indications
Uses
Hypogammaglobulinaemia pre/post stem cell transplant: Replacement therapy
Primary immunodeficiency syndromes with impaired antibody production
Secondary hypogammaglobulinaemia in CLL or Myeloma with recurrent infection
Replacement therapy in primary immunodeficiency syndromes such as:
Primary immunodeficiency syndrome with impaired antibody production.
Replacement therapy in myeloma or chronic lymphatic leukaemia with severe secondary hypogammaglobulinaemia and recurrent infections.
Treatment of hypogammaglobulinaemia in patients pre and post-allogeneic haematopoietic stem cell transplantation.
Dosage
Treatment should be initiated and monitored under the supervision of a physician experienced in the treatment of immunodeficiency, and in the guidance of patients for home treatment if applicable.
The dose and dosage regimen is dependent on the indication, and may need to be individualised for each patient depending on the pharmacokinetic and clinical response.
IgG trough levels should be measured in order to adjust the dose and dosage interval.
The following dosage regimens are given as a guideline.
Adults
The dosage regimen using the subcutaneous route should achieve a sustained IgG level.
Loading dose: At least 200mg/kg to 500mg/kg may be required (certain brands advise that the dose should be spread over several days with a maximum daily dose of 150mg/kg).
Once IgG levels are stabilised, maintenance doses are administered at intervals to reach a cumulative monthly dose which varies between different product brands (consult specific product literature for details).
Children
Different brands give varying instructions for use in children.
(See Dosage; Adult).
Additional Dosage Information
The patient will be instructed in the use of a syringe driver, infusion techniques, the keeping of a treatment diary, and measures to be taken in case of severe adverse events.
Once the patient is familiar with the method and no unacceptable side effects were observed during the training phase, the treatment may be continued at home by the patient or carer.
Administration
For subcutaneous infusion only.
Infusion rates may vary between brands (consult specific product literature).
It may be suitable or it may be required to use more than one pump simultaneously, more than one injection site can be used.

Advise patient on the symptoms of Aseptic Meningitis Syndrome
Use with caution in patients deficient in IgA. These patients may produce anti-IgA antibodies, which could lead to anaphylactic reactions.
Treatment should be initiated and monitored under the supervision of a physician experienced in the treatment of immunodeficiency, and in the guidance of patients for home treatment if applicable. The patient will be instructed in the use of a syringe driver, infusion techniques, the keeping of a treatment diary, and measures to be taken in case of severe adverse events. Once the patient is familiar with the method and no unacceptable side effects have been observed during the training phase, the treatment may be continued at home by the patient or carer.
Intravenous administration is contraindicated and if accidental administration into a blood vessel occurs the patient could develop shock.
Pregnancy and Lactation
Pregnancy
Use normal human immunoglobulin with caution in pregnancy.
The safety of this product for use during human pregnancy has not been established in controlled clinical trials. Therefore, normal human immunoglobulins should only be given with caution in pregnant women. Clinical experience with immunoglobulins suggests that no harmful effects on the course of the pregnancy, or to the foetus or neonate are to be expected.
Continued treatment of the pregnant women is important to ensure that the neonate is born with appropriate passive immunity.
Human immunoglobulins cross the placenta. The amounts that cross to the foetus vary in the course of the pregnancy, possibly as a function of gestational age, duration of treatment and/or the method of preparation of the immunoglobulins (Briggs 2015, Schaefer 2015).
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).
Lactation
Use normal human immunoglobulin with caution in breastfeeding.
UK licensed product information stresses that the safety of human immunoglobulins during breastfeeding has not been established in controlled clinical trials. It therefore concludes that human immunoglobulins should only be given with caution to breastfeeding mothers. However, it should be noted that immunoglobulins are a natural constituent of breast milk.
It is not known whether therapy with immunoglobulins results in any significant excess levels in milk, even when large intravenous doses are administered to the mother.
LactMed (2018), state that no serious adverse effects have been reported in infants whose mothers were treated with immunoglobulins, apart from a transient rash that occurred one day after the dose was administered to the mother.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.

Effects on Laboratory Tests
After administration 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.
Passive transmission of antibodies to erythrocyte antigens e.g. A,B,D may interfere with some serological tests for red cell antibodies for example the direct anti-globulin test (DAT, direct Coombs test).
Overdosage
It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
