Rabies immunoglobulin (RIG) is a medication made up of antibodies against the rabies virus.[8] It is used to prevent rabies following exposure.[8] It is given after the wound is cleaned with soap and water or povidone-iodine and is followed by a course of rabies vaccine.[8] It is given by injection into the site of the wound and into a muscle.[8] It is not needed in people who have been previously vaccinated against rabies.[9]

Common side effects include pain at the site of injection, fever, and headache.[8] Severe allergic reactions such as anaphylaxis may rarely occur.[10] Use during pregnancy is not known to harm the baby.[8] It works by binding to the rabies virus before it can enter nerve tissue.[8] After the virus has entered the central nervous system, rabies immunoglobulin is no longer useful.[8]

The use of rabies immunoglobulin in the form of blood serum dates from 1891.[11] Use became common within medicine in the 1950s.[12] It is on the World Health Organization's List of Essential Medicines.[13] Rabies immunoglobulin is expensive and hard to come by in the developing world.[14] In the United States it is estimated to be more than US$1,000 per dose.[15] Some versions are made from the blood plasma of people or horses who have high levels of the antibody in their blood.[8][15] The horse version is less expensive but has a higher rate of side effects.[15][12] A number of monoclonal antibody versions are also avaialble.[16]

### Names[edit | edit source]

There are a number of versions of rabies immunoglobulin licensed and available in the US.[19] Imogam Rabies-HT is produced by Sanofi Pasteur.[4] Kedrab is produced by Kedrion Biopharma.[17][5] Hyperrab is produced by Grifols.[6]

Imogam Rabies-HT and Kedrab have a nominal potency of 150 IU/mL while Hyperrab has a nominal potency of 300 IU/mL and requires smaller dosing. All three versions are used for post-exposure[20] and indicate local infusion at the wound site with additional amount intramuscularly at a site distant from vaccine administration.[21]
