Hepabig 100 IU (Human Hepatitis B Immunoglobulin) is a sterile solution of specific IgG antibodies used for passive, short-term immunization against the Hepatitis B virus (HBV) . It provides immediate neutralization of the virus and is primarily used for post-exposure prophylaxis.
Mechanism of Action (Pharmacodynamics)
Antibody Neutralization: The active ingredient—immunoglobulin G (IgG) antibodies sourced from screened human plasma—binds directly to the Hepatitis B surface antigen (HBsAg).
Viral Clearance: This antigen-antibody binding neutralizes the virus, preventing it from attaching to and entering healthy liver cells.
Immunity Type: It provides passive immunity. It does not train the body to make its own antibodies and is not a vaccine.
Pharmacokinetics :
Onset of Action: Immediate upon administration.
Route of Administration: Exclusively administered via intramuscular (IM) injection, typically into a large muscle like the gluteal or deltoid.
Duration of Protection: Because the antibodies are slowly metabolized and cleared by the body, the protection is temporary, lasting roughly 3 to 6 months.
Concurrent Use: It is frequently administered alongside the Hepatitis B vaccine to trigger the body's long-term active immunity.
Indications
Post-Exposure Prophylaxis: Given following needlestick injuries, contact with infected blood, or sexual contact with an HBsAg-positive individual.
Perinatal Prevention: Administered to newborns born to mothers infected with Hepatitis B.
Liver Transplant: Used to prevent the reinfection of the transplanted liver in HBV patients.
Dosage & Administration
Dosing: The 100 IU dose is generally prescribed for infants or children, while higher strengths (e.g., 200 IU to 1000 IU+) may be required for adults depending on the exposure source and body weight.
Timing: For maximum efficacy, it must be administered as soon as possible after exposure, ideally within 24 to 48 hours.
Storage: Must be refrigerated at temperatures between 2°C and 8°C and should not be frozen.
