Drug Information:
Immune globulin is a sterile solution made from human plasma. It contains antibodies that protect you against infection from various diseases. Immune globulin intramuscular (IGIM, for injection into a muscle) is used to prevent infection with hepatitis A in people who travel to areas where this disease is common. IGIM will not prevent hepatitis B. IGIM is also used to help prevent infection after exposure to measles, chickenpox (varicella), or rubella. IGIM should not be used in place of routine vaccination against polio, varicella, mumps, or rubella. Learn more
