Globulins are simple proteins that provide immunity against disease.
A protein is made up of several amino acids, which are the microscopic building blocks that make up all cells. Many globulins are inherited, so that the body is able from birth to fight off bacteria and other infections. IVIG is used for maintenance treatment of people who are unable to produce sufficient amounts of immune globulin antibodies. IVIG can help prevent or treat infections such as meningitis, bacteremia, osteomyelitis, septic arthritis, acute sinusitis, pneumonia, acute mastoiditis, or abscess of an internal organ. Some pain, tenderness and muscle stiffness generally occur at the injection site and last for several hours.
