Rh Immune Globulin
What To Think About
Although Rh immune globulin is not given to a woman who has become sensitized to the Rh factor, it is not harmful to a sensitized woman.
The dosage of Rh immune globulin can be adjusted to protect against exposure to varying amounts of Rh-positive blood. Exposure to large amounts of Rh-positive blood—caused by an injury, accidental transfusion with Rh-positive blood, or complication during labor and delivery—will require a higher dose of Rh immune globulin. A smaller-than-average dose may be given after an ectopic pregnancy, molar pregnancy, induced abortion, or miscarriage (spontaneous abortion) in early pregnancy.
If given within 3 months of a live virus Reference immunization Opens New Window, Rh immune globulin may block the benefit of the immunization. Your doctor will be able to tell you whether you need another immunization.
