Rho(D) immune globulin (Rho(D) immune globulin (human)) — Uses, Dosage, Side Effects & Safety

Drug class: Immune globulin (anti-D immunoglobulin)

Overview

Rho(D) immune globulin is a medication used to prevent Rh immunization, a condition that can occur when an Rh-negative individual is exposed to Rh-positive blood. This is most commonly needed during pregnancy, childbirth, or after certain medical procedures if the mother is Rh-negative and the baby is or may be Rh-positive. It helps protect future pregnancies by preventing the mother's immune system from developing antibodies against Rh-positive blood cells. The medication works by providing ready-made antibodies (anti-D immunoglobulin) that neutralize any Rh-positive red blood cells that may have entered the bloodstream. This prevents the mother's immune system from reacting and forming its own antibodies, which could harm future pregnancies. Key points: Rho(D) immune globulin is given as an injection, usually in the arm or buttock. It is safe for both mother and baby when used as directed. It does not treat existing Rh sensitization but prevents it from occurring.
