How does RhoGAM® Ultra-Filtered PLUS work?
RhoGAM® RhoGAM® Ultra-Filtered PLUS is a sterile solution that contains antibodies to the Rh factor. The antibodies are derived from human plasma. When RhoGAM® Brand is injected into the muscle of an Rh-negative mother, these antibodies circulate in her bloodstream and protect her against any Rh-positive red blood cells from the fetus. Her immune system then sees no need to take further action.
