Synonyms
RIG

Pharmacological Index

Immune Globulin


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


Pregnancy Risk Factor

C


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


Dental Health: Local Anesthetic/Vasoconstrictor Precautions

No information available to require special precautions


Dental Health: Effects on Dental Treatment

No effects or complications reported


Nursing Implications

Severe adverse reactions can occur if patient receives RIG I.V.


Dosage Forms

Injection: 150 units/mL (2 mL, 10 mL)
