Description
Introduction Of Berirab P 300iu Injection:
Berirab P 300iu Injection is used with rabies vaccine to prevent Rabies. It works by giving your body the antibodies it needs to protect against the rabies virus. It is administered only once, at the beginning of anti-rabies prophylaxis, to previously unvaccinated persons.
It is given as an injection by a doctor or nurse. It must always be used in combination with a rabies vaccine. Post-exposure prophylaxis consists of a regimen of one dose of immunoglobulin and full courses of rabies vaccination. This should be given as soon as possible after exposure. Both active (vaccine) and passive immunization (Immunoglobulin) prevent the rabies virus from infiltrating the central nervous system, but become ineffective once the virus has crossed into the central nervous system. Berirab P Injection is administered only once in a lifetime.
The most common side effects include pain, anaphylactic reaction, angioedema (swelling of deeper layers of skin), injection site stiffness, soreness, and tenderness. They do not normally last very long. Sitting or lying down can sometimes help. Consult your doctor if any of the side effects persist or worry you.
Before having the injection, you should tell your doctor if you’ve ever had an allergic reaction to an immunoglobulin. Some other medicines may react with the human rabies immunoglobulin so talk to your doctor about other medications you are taking as well. You should consult your doctor first if you are pregnant or breastfeeding.
Active Ingredient/Salt:
- Human Rabies Immunoglobulin
Uses Of Berirab P 300iu Injection:
Berirab P 300iu Injection 2ML is used for the following purposes:
- Rabies post-exposure prevention: After a bite, scratch, or lick from a potentially rabid animal, BERIRAB P 300IU INJECTION 2ML provides immediate, temporary antibodies to neutralise the virus at the wound site before the rabies vaccine can stimulate your own immune response.
- Immediate passive immunisation: For individuals who have never been immunised against rabies and have been exposed to the virus, BERIRAB P 300IU INJECTION 2ML delivers rapid defence during the critical window before active immunity develops.
Benefits Of Berirab P 300iu Injection:
Berirab P 300iu Injection provides immediate passive protection against rabies after potential exposure. When used together with the rabies vaccine, it helps prevent the virus from spreading while your body develops its own immune response. Its benefits include:
- Provides Immediate Protection: Supplies ready-made antibodies that help neutralise the rabies virus immediately after exposure.
- Supports Rabies Post-Exposure Treatment: Works alongside the rabies vaccine to provide protection until active immunity develops.
- Acts at the Site of Exposure: When infiltrated around the wound, it helps neutralise the virus where it may have entered the body.
- Reduces the Risk of Rabies Infection: Early administration as part of recommended post-exposure prophylaxis helps prevent rabies, a life-threatening disease.
How Berirab P 300iu Injection Works:
Berirab P 300iu Injection contains rabies immunoglobulin, which provides immediate passive immunity against the rabies virus after potential exposure. It contains ready-made antibodies that bind to and neutralise the rabies virus at the site of exposure, helping prevent the virus from entering the nervous system before the body’s own immune response develops. Rabies immunoglobulin is administered by infiltrating as much of the dose as possible into and around the wound, with any remaining dose injected into a muscle at a different site. This provides immediate but temporary protection until the rabies vaccine stimulates the body to produce its own long-lasting antibodies against the virus.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them.
