CMV IG is used to help prevent infection by cytomegalovirus in people who receive an organ transplant (kidney, heart, liver, lung, or pancreas).

CMV IG may also be used for purposes not listed in this medication guide.

CMV IG is made from human plasma (part of the blood) which may contain viruses and other infectious agents. Donated plasma is tested and treated to reduce the risk of it containing infectious agents, but there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.

It is not known whether CMV IG passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How is CMV IG given?

CMV IG is injected into a vein through an IV. A healthcare provider will give you this injection.

CMV IG is usually given within 72 hours after your transplant. You will then receive several more doses every 2 to 4 weeks afterward.

While receiving CMV IG, you may need frequent blood tests. Your kidney function may also need to be checked.

What happens if I miss a dose?

Call your doctor for instructions if you miss a dose of CMV IG.

What happens if I overdose?

What should I avoid while receiving CMV IG?

Do not receive a "live" vaccine while using CMV IG. The vaccine may not work as well during this time, and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.

What other drugs will affect CMV IG?

CMV IG can harm your kidneys. This effect is increased when you also use certain other medicines, including: antivirals, chemotherapy, injected antibiotics, medicine for bowel disorders, medicine to prevent organ transplant rejection, injectable osteoporosis medication, and some pain or arthritis medicines (including aspirin, Tylenol, Advil, and Aleve).

Other drugs may interact with cytomegalovirus immune globulin, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
