Human Rabies Immunoglobulin

Human Rabies Immunoglobulin (HRIG) is a life-saving medication used to provide immediate protection against rabies after exposure to a potentially rabid animal. It contains antibodies that neutralize the rabies virus, preventing the infection from spreading before the body can produce its own immune response. HRIG is used in combination with rabies vaccination as part of post-exposure prophylaxis (PEP). It is injected around the wound site to provide passive immunity. Since rabies is almost always fatal once symptoms appear, timely administration of HRIG is crucial to preventing the disease.

Uses of Human Rabies Immunoglobulin

• Post-exposure prophylaxis (PEP) for rabies
• Immediate passive immunity against rabies virus
• Used in conjunction with rabies vaccine
• Recommended for individuals bitten by rabid or suspected rabid animals
• Protects individuals who have not been previously vaccinated

How Human Rabies Immunoglobulin Works

Human Rabies Immunoglobulin works by providing immediate passive immunity through antibodies that neutralize the rabies virus at the wound site. Since the rabies vaccine takes time to stimulate an active immune response, HRIG serves as a temporary protection until the body produces its own antibodies. It is administered only once as part of post-exposure prophylaxis, ensuring early defense against the virus.

Benefits of Human Rabies Immunoglobulin

• Provides immediate protection against rabies
• Essential for individuals exposed to rabies who have not been vaccinated
• Reduces the risk of developing rabies infection
• Administered directly at the wound site for maximum effectiveness
• Safe and effective when used as part of post-exposure treatment
• Prevents the progression of rabies, which is otherwise fatal

How to Take Human Rabies Immunoglobulin

Human Rabies Immunoglobulin is administered by a healthcare professional. It is injected around the wound site as soon as possible after exposure. The remaining dose may be given intramuscularly at a different site from the rabies vaccine. It is given only once as part of post-exposure prophylaxis. The rabies vaccine series must be completed for full protection.

Q. What is Human Rabies Immunoglobulin used for?
A. It is used to provide immediate passive immunity against rabies for individuals exposed to a potentially rabid animal.

Q. Is Human Rabies Immunoglobulin a vaccine?
A. No, it is not a vaccine. It provides temporary protection while the rabies vaccine helps the body develop long-term immunity.

Q. How soon should Human Rabies Immunoglobulin be given after exposure?
A. It should be administered as soon as possible, ideally within 24 hours of exposure, along with the rabies vaccine.

Q. Can I receive HRIG if I have been previously vaccinated for rabies?
A. No, if you have completed a rabies vaccination series before exposure, you do not need HRIG, only booster doses of the rabies vaccine.

Q. Is Human Rabies Immunoglobulin safe for children?
A. Yes, it is safe for children and is essential for preventing rabies after exposure.

Q. Does Human Rabies Immunoglobulin cause serious side effects?
