2. QUALITATIVE AND QUANTITATIVE COMPOSITION
1.5 ml of the solution contains:
Human hepatitis B immunoglobulin 1000 IU
For excipients, see section 6.1.
3. PHARMACEUTICAL FORM
Solution for injection
Transparent or slightly opalescent solution,
4. CLINICAL PARTICULARS
4.1 Therapeutic indications
The product is intended for:
l) adults and children not vaccinated against Hepatitis B and especially exposed to the risk of FIBV nonsocomial infection,
2) medical personnel not vaccinated against Hepatitis B, following exposure to HBV including: needle stick, injury in a cut, wound contamination or contamination through mucous membranes,
3) sexual partners of patients with acute Hepatitis B
4.2 Posology and method of administration
Gamma anty-HBs 1000 should be administered intramuscularly:
l . Adults and children weighing 50 kg and more: 1000 IU is administered, and in the case of a long hospital stay the dose (1000 IU) is repeated every 3-4 weeks.
2. Medical personnel: 1000 IU as soon as possible, however within max. 48 hours after exposure to 1-1BV and another dose of 1000 IU after 4 weeks, provided that a series of vaccinations against Hepatitis B has not already been staffed.
3. Sexual partners of patients with acute Hepatitis B: 1000 IU as soon as possible, within max. 14 days after occurrence of Hepatitis B in the partner, and another dose of 1000 IU after 4 weeks, provided that a series of vaccinations against Hepatitis B has not already been started.
In such situations, vaccination against Hepatitis B is highly recommended. The first dose of the vaccine can be administered on the same day as human immunoglobulin against Hepatitis B however in different sites.
If contraindications for intramuscular injections exist (coagulation impairment), the product can be administered subcutaneously, provided that no product for intravenous administration is available. It should be noted, however, that no clinical data about efficiency of subcutaneous administration of GAMMA anty-HBs 1000 is available.
Contraindications for use include:
– hypersensitivity to human immunoglobulin, especially in patients with immunoglobulin A deficiency and circulating anti-IgA antibodies,
– known hypersensitivity to any of the product components.
GAMMA anty-HBs 1000 must not be administered intravenously.
4.4 Special warnings and precautions for use
Make sure GAMMA anty-HBs 1000 is not administered directly to a blood vessel due to the risk of shock.
If the recipient carries HBsAg, product administration does not produce any benefits.
Hypersensitivity reactions occur seldom.
Sometimes, human immunoglobulin against Hepatitis B evokes a drop in blood pressure combined with anaphylactic reactions, even in the case of patients who tolerated previous treatment with human immunoglobulin.
In the case of suspected allergic or anaphylactic reaction, product injection should be discontinued immediately. In the case of shock, a standard medical procedure should be followed.
Gamma anty-HBs 1000 is derived from human plasma collected from donors with a high level of anti-HBs antibodies. The manufacturing technique is based on the fractionation of plasma with cold ethyl alcohol according to the Cohn procedure. In the case of administration of products obtained from human blood or plasma, the transmission of infectious agents cannot be completely excluded. This refers also to pathogens and viruses unknown before. However, the risk of transmitting infectious agents is minimised by:
– selection of donors based on clinical anamnesis and testing of both, a single plasma unit and pooled plasma for the presence of HBsAg, anti-HIV and anti-HCV antibodies.
– testing of pooled plasma for the presence of the genetic material from the virus of hepatitis type C (HCV).
– applied inactivation/elimination of viruses in the manufacturing process, validated using model viruses.
Undertaken safety measures which are considered as efficient apply to enveloped viruses, such as: HIV, HBV and HCV. However, they can have a limited efficiency for non-enveloped viruses, such as virus of hepatitis type A (HAV) and/or parvovirus B19.
Clinical data exists which confirms lack of transfer of hepatitis A virus (HAV) and B19 parvovirus during immunoglobulin use. Also, the presence of antibodies is presumed to play an important role for viral safety of the product.
It is recommended, for patient’s safety, as far as possible, to record the name and lot number of the Gamma anty-HBs 1000 product together with the patient data after each application of the medicine, in order to correlate the product lot number to a given patient.
4.5 Interaction with other medicinal products and other forms of interaction
Vaccines containing live attenuated viruses
Administration of immunoglobulin may disturb the development of immune response to vaccines containing live attenuated viruses, such as rubella, mumps, measles or chicken pox for a period of 3 months. The administration of Gamma anty-HBs 1000 should be followed by at least a 3-month pause before the administration of a vaccine containing live attenuated viruses.
Human immunoglobulin against Hepatitis B should be administered three to four weeks following administration of a vaccine containing live attenuated viruses; if administration of immunoglobulin against Hepatitis B is vital in the period of three to four weeks after vaccination, another vaccine should be administered three months after administration of immunoglobulin against Hepatitis B.
Disturbance of serological tests
After injecting immunoglobulin, a temporary increase in the levels of various passively transferred antibodies in the patient’s blood may be observed, which may result in falsely positive results of serological tests
Passive transfer of antibodies against antigens of erythrocytes, e.g. A, B, D, may impair the results of some serological tests for the presence of antibodies reacting with red blood cells, e.g. direct antiglobulin test (Coombs test).
4.6 Fertility, pregnancy and lactation
The product can be used by pregnant women.
The product can be used by breast-feeding women.
4.7 Effects on ability to drive and use machines
Gamma anty-HBs 1000 has no effects on the ability to drive or use machines.
4.8 Undesirable effects
Like all medicines, Gamma anty-HBs 1000 can cause adverse reactions.
There is no sufficient clinical data about the frequency of occurrence of adverse reactions. The following adverse reactions have been observed:
