Rho(D) Immune Globulin is a medicine given by intramuscular injection that is used to prevent the immunological condition known as Rhesus disease (or hemolytic disease of newborn). The medicine is a solution of IgG anti-D (anti-RhD) antibodies that bind to, and lead to the destruction of, fetal Rh D positive red blood cells that have passed from the fetal circulation to the maternal circulation. Therefore, in a Rhesus negative mother it can prevent sensitization of the maternal immune system to Rh D antigens, which can cause rhesus disease in the current or in subsequent pregnancies. With the widespread use of Rho(D) Immune Globulin, Rh disease of the fetus and newborn has almost disappeared.
