What is Rho(D) IG?

Rho(D) immune globulin (Rho(D) IG) is a sterilized solution made from human blood. Rh is a substance that most people have in their blood (Rh positive) but some people don"t (Rh negative). A person who is Rh negative can be exposed to Rh positive blood through a mismatched blood transfusion or during pregnancy when the baby has the opposite blood type. When this exposure happens, the Rh negative blood will respond by making antibodies that will try to destroy the Rh positive blood cells. This can cause medical problems such as anemia (loss of red blood cells), kidney failure, or shock.

Rho(D) IG is used to prevent an immune response to Rh positive blood in people with an Rh negative blood type. Rho(D) IG may also be used in the treatment of immune thrombocytopenic purpura (ITP).

Rho(D) IG may also be used for purposes other than those listed here.

What is the most important information I should know about Rho(D) IG?

Rho(D) IG is made from human plasma (part of the blood) and may contain viruses and other infectious agents that can cause disease. Although Rho(D) IG is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.

If you are an Rh-negative woman and you become pregnant, you must tell your doctor if you have ever been exposed to Rh-positive blood in your lifetime. This includes exposure from a mismatched blood transfusion, or exposure during your first pregnancy. Your history of exposure and treatment will be extremely important to each and every one of your pregnancies.

What should I discuss with my healthcare provider before using Rho(D) IG?

• an allergy to human immune globulin;

• a bleeding disorder (such as hemophilia); or

• immune globulin A (IgA) deficiency.

If you have any of these conditions, you may not be able to receive Rho(D) IG, or you may require a dosage adjustment or special tests during treatment.

Rho(D) IG is used during and after pregnancy. This medication is not known to be harmful to a baby during pregnancy or while breast-feeding.
