Prevents hepatitis B infection in patients who are known to have been exposed, including neonates born to HBsAg-positive women, by providing passive immunity.
An immune gamma-globulin fraction containing high titers of antibodies to the hepatitis B surface antigen. Confers passive immunity to hepatitis B infection.
Prevention of hepatitis B infection.
Absorption: Slowly absorbed after IM administration.
Distribution: Unknown. Probably crosses the placenta.

Half-life: 21 days.
Time/action profile (development of anti-HBs antibodies)
|IM||1–6 days||3–11 days||2–6 mo|
Contraindicated in: Hypersensitivity to immune globulins, glycine, or thimerosal.
Use Cautiously in: Thrombocytopenia; IgA deficiency; Lactation: Lactation; Obstetric: Has been used during pregnancy.
Adverse Reactions/Side Effects
Central nervous system
- erythema at IM site
- joint pain
- allergic reactions including anaphylactic shock and angioedema (life-threatening)
Drug-Drug interactionMay interfere with the immune response to live-vaccines.
Intramuscular (Adults) 0.06 mL/kg (usual dose 3–5 mL) within 7 days of exposure, repeated 28–30 days after exposure.
Intramuscular (Neonates) 0.5 mL within 12 hr of birth.
Injection: 0.5-mL prefilled syringes, 1-, 4-, 5-mL vials
- For passive immunity, determine the date of exposure to infection. Hepatitis B immune globulin should be administered preferably within 24 hr but not later than 7 days after exposure to hepatitis B.
- Assess patient for signs of anaphylaxis (hypotension, flushing, chest tightness, wheezing, fever, dizziness, nausea, vomiting, diaphoresis) after administration. Epinephrine and antihistamines should be available for treatment of anaphylactic reactions.
Potential Nursing DiagnosesRisk for infection (Indications)
- Solution for injection is clear, slightly amber, and viscous. Keep refrigerated.
- If administered with hepatitis B virus vaccine, do not administer via same syringe or into same injection site.
- Intramuscular: Administer hepatitis B immune globulin (HBIG) in adults and children into the deltoid muscle or anterolateral thigh. The gluteal site should be used only in adults with injections of large volumes or when large volumes are divided into multiple doses.
- Do not administer IV.
- Explain to patient the use and purpose of hepatitis B immune globulin therapy. Discuss methods of transmission and vaccination for prophylaxis.
- Advise patient to report symptoms of anaphylaxis immediately.
- Inform patient that pain, tenderness, swelling, and erythema at the injection site may occur after IM injections.
- Prevention of hepatitis B infection in exposed patients by providing passive immunity.
