Berirab P 300IU 2ml Injection contains Rabies Immunoglobulin, used for immediate passive immunization against the rabies virus following suspected or confirmed exposure such as animal bites or scratches.

It provides instant antibodies against the rabies virus until the body can produce its own immune response after vaccination.
