Description

Rabies immune globulin (RAY-beez im-MUNE GLOB-yoo-lin) is used along with rabies vaccine to prevent infection caused by the rabies virus. Rabies immune globulin works by giving your body the antibodies it needs to protect it against the rabies virus. This is called passive protection. This passive protection lasts long enough to protect your body until your body can produce its own antibodies against the rabies virus.

Rabies immune globulin is given to persons who have been exposed (for example, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies immune globulin is used only in persons who have never before received the rabies vaccine.

Rabies infection is a serious, and often fatal, infection. In the U.S., rabies in wild animals, especially raccoons, skunks, and bats, accounts for most cases of rabies passed on to humans, pets, and other domestic animals. In Canada, the animals most often infected with rabies are foxes, skunks, bats, dogs, and cats. Horses, swine, and cattle also have been known to become infected with rabies. In much of the rest of the world, including Latin America, Africa, and Asia, dogs account for most cases of rabies passed on to humans.

If you are being (or will be) treated for a possible rabies infection while traveling outside of the U.S. or Canada, contact your doctor as soon as you return to the U.S. or Canada, since it may be necessary for you to have additional treatment.

Rabies immune globulin is to be administered only by or under the supervision of your doctor or other health care professional. It is available in the following dosage form:

    Parenteral
  • Injection (U.S. and Canada)
