How does RhoGAM injections work?

RhoGAM injections contain Rh immunoglobulin, which prevents the immune system of an Rh-negative mother from producing antibodies against Rh-positive fetal red blood cells. If fetal blood cells enter the mother's circulation, RhoGAM binds to these cells and helps to clear them from her system before her immune system can react. This is particularly important during pregnancy and after delivery to prevent hemolytic disease of the newborn in future pregnancies. Administering RhoGAM at the appropriate times effectively reduces the risk of complications related to Rh incompatibility.
