|
Use |
|
Part of postexposure prophylaxis of persons with rabies exposure who lack a
history of pre-exposure or postexposure prophylaxis with rabies vaccine or a
recently documented neutralizing antibody response to previous rabies
vaccination; although it is preferable to administer RIG with the first dose of
vaccine, it can be given up to 8 days after vaccination |

Contraindications |
|
Inadvertent I.V. administration; allergy to thimerosal or any
component |
|
|
Warnings/Precautions |
|
Use with caution in individuals with thrombocytopenia, bleeding disorders, or
prior allergic reactions to immune globulins |
|
|
Adverse
Reactions |
|
1% to 10%:
Central nervous system: Fever (mild)
Local: Soreness at injection site
<1%: Urticaria, angioedema, stiffness, soreness of muscles, anaphylactic
shock |
|
|
Drug
Interactions |
|
Decreased effect: Live virus vaccines (eg, MMR, rabies) may have delayed or
diminished antibody response with immune globulin administration; should not be
administered within 3 months unless antibody titers dictate as
appropriate |
|
|
Stability |
|
Refrigerate |
|
|
Mechanism of
Action |
|
Rabies immune globulin is a solution of globulins dried from the plasma or
serum of selected adult human donors who have been immunized with rabies vaccine
and have developed high titers of rabies antibody. It generally contains 10% to
18% of protein of which not less than 80% is monomeric immunoglobulin
G. |
|
|
Usual Dosage |
|
Children and Adults: I.M.: 20 units/kg in a single dose (RIG should always be
administered as part of rabies vaccine (HDCV)) regimen (as soon as possible
after the first dose of vaccine, up to 8 days); infiltrate
1/2
of the dose locally around the wound; administer the remainder I.M.
|
|
|
Administration |
|
Intramuscular injection only; severe adverse reactions can occur if
patient receives RIG I.V.; injection should be made into the deltoid muscle
or anterolateral aspect of the thigh |
