Human Hepatitis B Immunoglobulin

Human Hepatitis B Immunoglobulin (HBIG) is a blood product derived from human plasma that contains antibodies against the Hepatitis B virus (HBV). It is used to provide passive immunity to individuals who have been exposed to HBV, especially in post-exposure situations like accidental needle sticks or sexual exposure. HBIG helps to prevent the development of a Hepatitis B infection by neutralizing the virus. It is typically administered alongside the Hepatitis B vaccine to offer immediate protection and is used in both adults and infants at risk of infection.

Uses of Human Hepatitis B Immunoglobulin

• Prevents Hepatitis B infection after exposure to the virus
• Used for post-exposure prophylaxis in cases of accidental needle sticks or exposure during childbirth
• Administered to infants born to mothers infected with Hepatitis B to prevent transmission
• Used in individuals with compromised immune systems at high risk for HBV exposure

How Human Hepatitis B Immunoglobulin works

Human Hepatitis B Immunoglobulin works by providing immediate passive immunity to individuals who have been exposed to the Hepatitis B virus. The immunoglobulin contains antibodies that neutralize the virus and prevent it from infecting the liver. It is most effective when given shortly after exposure to the virus, offering immediate protection while the body builds its own immune response through vaccination.

Benefits of Human Hepatitis B Immunoglobulin

• Provides immediate protection against Hepatitis B after exposure to the virus
• Reduces the risk of developing chronic Hepatitis B infection
• Can be used for both pre- and post-exposure prophylaxis
• Prevents transmission of Hepatitis B from mother to infant during childbirth
• Safe and effective when used in combination with the Hepatitis B vaccine

Human Hepatitis B Immunoglobulin is administered via an intramuscular (IM) injection, typically given by a healthcare provider. The dosage and frequency of administration depend on the type of exposure and the individual’s risk factors. It is important to receive the immunoglobulin as soon as possible after exposure to the Hepatitis B virus to maximize effectiveness. If required, the Hepatitis B vaccine may also be given alongside HBIG for long-term protection.
