Rho(D) immune globulin
Abbreviation: Rhogam
Rho(D) immune globulin is an injection given to Rh-negative pregnant women to prevent their immune system from reacting to Rh-positive fetal blood cells. It works by clearing any fetal Rh-positive cells from the mother's circulation before her body can form antibodies against them. It is typically given around 28 weeks of pregnancy, and again within 72 hours after birth if the baby is confirmed Rh positive. It is also given after events such as miscarriage, amniocentesis, or vaginal bleeding during pregnancy. The brand name RhoGAM is commonly used, though other formulations exist. This injection is highly effective at preventing Rh sensitization.
