Human Anti-D Immunoglobulins


Pregnancy and Other Obstetrical Conditions in Rh-Negative Women, Unless the Father or Baby are Conclusively Rh Negative:
  • Pregnancy/delivery of an Rh-positive baby irrespective of the ABO groups of the mother and baby
  • Abortion/threatened abortion at any stage of gestation
  • Ectopic pregnancy
  • Antepartum fetal-maternal hemorrhage (suspected or proven) resulting from antepartum hemorrhage (e.g., placenta previa), amniocentesis, chorionic villussampling, percutaneous umbilical blood sampling, other obstetrical manipulative procedure (e.g., version) or abdominal trauma
  • Transfusion of Rh incompatible blood or blood products
Transfusion: Prevention of Rh immunization in any Rh-negative person after incompatible transfusion of Rh-positive blood or blood products (e.g., red blood cells, plateletconcentrates, granulocyte concentrates)


Anti-D immunoglobulin prevents a rhesus-negative mother from actively forming antibodies to foetal rhesus-positive RBCs that may pass into the maternal circulation during childbirth, abortion, or certain other sensitising events. It is also used in idiopathic thrombocytopenic purpura to prevent excessive bleeding.

Dosage & Administration

One dose 250 mcg should be given IM immediately or as soon as possible after delivery, or abortion of a Rh-positive child, preferably within 48 hours, but not later than 72 hours post-partum.

Following any potentially sensitizing episode (e.g stillbirth, amniocentesis) up to 20 weeks of gestation 125 mcg per episode (after 20 weeks of gestation, 250 mcg) immediately or within 72 hours.

For antenatal prophylaxis 250 mcg should be given in week 28 & also week 34 of pregnancy. The injection must only be given deep intramuscularly. Do not inject intravenously.


Live vaccines should only be admin at least 3 mth after the last dose of immunoglobulin admin.
