An immune globulin infusion is an intravenous medication that doctors administer to patients who have a variety of immune disorders, states Drugs.com. Immune globulin infusions contain antibodies that can protect the patient from getting an infection.
Immune globulin infusions contain sterilized blood plasma. The antibodies found within the blood plasma can help a patient's immune system fight off certain infections. Doctors most commonly use this treatment to treat primary immunodeficiency and other diseases that may reduce the efficiency of the immune system, according to Drugs.com. It is a relatively safe treatment, but it may cause blood clots in some patients.
