You may not be able to use this medicine if:

• you have had an allergic reaction to an immune globulin or blood product;
• you have immune globulin A (IgA) deficiency with antibody to IgA; or

IGIV can cause blood clots or kidney problems, especially in older adults or in people with certain conditions. Tell your doctor if you have ever had:

You may need a dose adjustment if you are exposed to measles, or if you travel to an area where this disease is common.

Tell your doctor if you are pregnant or breastfeeding.

Immune globulin is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.

Use Immune Globulin (Privigen) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
