CSL Behring


Full Prescribing Info
Human rabies immunoglobulin.
Each mL of solution for injection contains human protein immunoglobulin (at least 95%) 100-170 mg, with antibodies to rabies virus at least 150 IU.
It also contains the following excipients: Aminoacetic acid (glycine), sodium chloride, hydrochloric acid or sodium hydroxide (in small amounts for pH adjustment), water for injections.
Immune sera and immunoglobulins, human rabies immunoglobulin. ATC Code: J06BB05.
Post-exposure prophylaxis of rabies infection after exposure to scratches, bites or other injuries caused by a suspected rabid animal; mucous membrane contamination with infectious tissue or saliva of a suspected rabid animal; contact of mucous membranes or newly skin injury with rabies live attenuated vaccine eg, vaccination baits.
Human rabies immunoglobulin must always be used in combination with a rabies vaccine.
National and/or World Health Organization (WHO) guidelines regarding protection against rabies should be observed.
Dosage/Direction for Use
Post-exposure prophylaxis consists of a regimen of a dose of immunoglobulin and full courses of rabies vaccination. Rabies immunoglobulin and the first dose of rabies vaccine should be given as soon as possible after exposure. Additional doses of rabies vaccine should be given according to official guidelines or the manufacturer's instruction.
Rabies Prophylaxis Exclusively with Simultaneous Vaccination: Recommended Dose: 20 IU/kg body weight.
Because of the risk of interference with antibody production related to vaccination, neither the dose should be increased nor repeat rabies immunoglobulin be given even if the onset of the simultaneous prophylaxis is delayed.
Administration: Human rabies immunoglobulin should be administered via the IM route.
Do not use solutions which are cloudy or contain residues (deposits/particles).
Berirab P is a ready-to-use solution and should be administered at body temperature.
Of the total quantity of rabies immunoglobulin, as much as possible should be instilled deeply into and around the wound. The remainder is to be injected IM preferably into the vastus lateralis muscle with the patient lying down.
If comparatively large total volumes are required, it is advisable to administer them in divided doses at different sites. This applies in the case of doses >2 mL for children up to 20 kg body weight and doses >5 mL for persons >20 kg body weight.
The immunoglobulin and the vaccine should be administered at 2 different sites of the body.
The immunoprophylaxis should be carried out immediately even in case that suspicion is not clarified if the animal was infected. Wounds should not be primary sewed. Parts of the body that are possibly contaminated and all wounds are to be cleaned immediately with soap or detergent, washed well with water and treated with 70% alcohol or iodine tincture; this is also true for contamination with vaccine solution from vaccination baits.
In the presence of a coagulation disorder, in the case of which IM injections are contraindicated, Berirab P may also be given SC. Afterwards the injection site should be compressed with a swab.
However, it should be noted that there are no clinical efficacy data to support administration by the SC route.
Because of the life-threatening risk due to rabies, there are no contraindications to the administration of rabies immunoglobulin.
Special Precautions
Ensure that Berirab P is not administered into a blood vessel because of the risk of shock.
True hypersensitivity reactions are rare. Berirab P contains a small quantity of IgA. Individuals who are deficient in IgA have the potential for developing IgA antibodies and may have anaphylactic reactions after administration of blood components containing IgA.
Rarely human rabies immunoglobulin can induce a fall in blood pressure with anaphylactic reactions, even in patients who had tolerated previous treatment with human immunoglobulin.
Therapeutic measures depend on the nature and severity of the event. The current medical standards for shock treatment are to be observed.
Patients should be observed for at least 20 mins after administration of Berirab P.
Particularly in cases of inadvertent IV injection, patients should be observed for longer term (at least 1 hr) after administration.
Excipients: Berirab P contains <1 mmol sodium (23 mg) per dose ie, essentially sodium-free.
Virus Safety: 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 eg, HIV, HBV and HCV, and for the non-enveloped viruses, HAV and parvovirus B19.
There is reassuring clinical experience regarding the lack of hepatitis A or parvovirus B19 transmission with immunoglobulins and it is also assumed that the antibody content makes an important contribution to the viral safety.
It is strongly recommended that every time that Berirab P is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.
Effects on the Ability to Drive or Operate Machinery: No effects on the ability to drive and use machines have been observed.
Use in pregnancy & lactation: The safety of Berirab P for use in human pregnancy has not been established in controlled clinical trials. Long lasting clinical experience with immunoglobulins does indicate that no harmful effects on the course of pregnancy, on the foetus or the neonate are to be expected.
Use In Pregnancy & Lactation
Use in pregnancy & lactation: The safety of Berirab P for use in human pregnancy has not been established in controlled clinical trials. Long lasting clinical experience with immunoglobulins does indicate that no harmful effects on the course of pregnancy, on the foetus or the neonate are to be expected.
Adverse Reactions
In rare cases the following adverse reactions may occur: Allergic reactions including fall in blood pressure, dyspnoea, cutaneous reactions, in isolated cases reaching as far as anaphylactic shock, even when the patient has shown no hypersensitivity to previous administration of immunoglobulins; generalized reactions eg, chills, fever, headache, malaise, nausea, vomiting, arthralgia and moderate back pain; cardiovascular reactions particularly if the product is inadvertently injected intravascularly.
Local Reactions: At the injection site local pain, tenderness or swelling can be observed in rare cases.
For safety with respect to transmissible agents, see Precautions.
If patient experience reactions, especially those which are not mentioned, inform physician or pharmacist.
Drug Interactions
Vaccinations with Live Attenuated Virus Vaccines: Immunoglobulin administration may impair the efficacy of live attenuated virus vaccines eg, measles, rubella, mumps and varicella vaccines for a period of up to 3 months. After administration of Berirab P an interval of at least 3 months should elapse before vaccination with live virus vaccines. In the case of measles, this impairment may persist for up to 4 months. Therefore, patients receiving measles vaccine should have their antibody status checked.
Interference with Serological Testing: It has to be considered that when serological test results are interpreted, the transitory rise of passively transferred antibodies after immunoglobulin injection may result in misleading positive test results.
Passive transmission of antibodies to erythrocyte antigens eg, A, B and D may interfere with some serological tests for red cell allo-antibodies (eg, Coombs test).
Incompatibilities: In the absence of compatibility studies, Berirab P must not be mixed with other medicinal products, diluents or solvents.
Store at 2-8°C (refrigerator). Do not freeze. Protect from light.
Once the container has been opened, the content have to be used immediately.
Any unused product or waste material should be disposed of in accordance with local requirements.
