Human Anti-D Immunoglobulin is a medicine given to prevent the formation of the immune response in women with negative (Rh-negative) blood group who are exposed to the Rh antigen (from a positive blood group fetus) at the time of planned abortion or miscarriage (up to 12 weeks’ gestation). It also suppresses the stimulation of active immunity by Rh-positive fetal blood cells that may enter the maternal circulation at the time of delivery. It is also used for treating Idiopathic thrombocytopenic purpura in Rh-positive patients.
