Rho(D) immune globulin

Rho(D) immune globulin is a medication given to Rh-negative pregnant women to prevent their immune system from attacking Rh-positive fetal red blood cells. If a pregnant woman with Rh-negative blood is exposed to Rh-positive blood (such as from the fetus), her immune system might produce antibodies that could harm future pregnancies. Administering this medication, usually around the 28th week of pregnancy and within 72 hours after childbirth or injury, helps to prevent the formation of these antibodies, reducing the risk of hemolytic disease in the newborn. It's a safe and effective way to protect pregnancies from Rh incompatibility issues.
