Frequently asked questions
PlasmaRab Injection is a solution containing a large amount of rabies antibodies. It is used to provide protection against rabies. It is given either along with the first dose of anti-rabies vaccine(ARV) or not more than 7 days later.
Rabies is a 100% preventable disease. Proper wound management and simultaneous administration of PlasmaRab Injection combined with anti-rabies vaccine (ARV) is almost invariably effective in preventing rabies, even after high-risk exposure.
PlasmaRab Injection is not required for patients who have previously received a complete vaccination series of rabies.
Whether PlasmaRab Injection is painful or not depends on your pain tolerance. During your initial treatment, a healthcare professional will put PlasmaRab Injection in the area where you were bitten. This can be painful. Therefore, a relatively greater amount of PlasmaRab Injection may be required to be placed in and around the wound site to ease out your pain and treat infection.
Equine Rabies Immunoglobulin is more economical as compared to PlasmaRab Injection i.e., human rabies immunoglobulin (HRIG). Hence, it is more affordable to patients in developing countries, like India. However, Equine Rabies Immunoglobulin has a high potential to cause anaphylaxis (a severe, potentially life-threatening allergic reaction), serum sickness and other allergic reactions and thus physicians are hesitant to use it.
