Chhutani, "The injection is typically given at 28 weeks gestation because it will last for about 12 weeks. One last dose of immunoglobulin will prevent the mother's body from producing antibodies that may place future pregnancies at risk. RhoGAM side effects are usually mild and don't harm the baby or affect breastfeeding. Less common side-effects can include allergic reaction, headache, joint or muscle pain, and fatigue. If any of these are experienced, you should talk to your doctor.

It is hopefully clear already that not everyone is at risk to develop Rh immunization and so not everyone needs RhoGAM. Some folks can safely skip their RhoGAM shot, but only because it would never have been recommended for them in the first place. While an ABO incompatibility can also cause hemolytic disease of the newborn, it is usually much more minor. What is the chance your baby will be Rh-positive? It depends. And is actually more complicated than people think.
The current guidelines are to get a RhoGAM shot at around the 28th week of pregnancy to prevent Rh sensitization for the rest of the pregnancy; within 72 hours after the delivery of an Rh-positive infant; after a miscarriage, abortion, or ectopic pregnancy; or after amniocentesis or chorionic villus sampling. You will know if you are already Rh sensitized because a blood test is done to check for Rh antibodies.
When paternity is certain you know who the father is , and the father is Rh-negative, you can also skip the shot you would get at 28 weeks. How do you know if you are already Rh sensitized? Moms who are Rh-negative get an antibody screen to see if they have Rh antibodies when they are 28 to 29 weeks pregnant.
Why do some women seem to safely skip their RhoGAM shot and have a healthy baby? In the UK, they routinely give all Rh-negative mothers either one dose of RhoGAM at weeks or two doses, one at 28 weeks and another at 34 weeks. New mums will also get a shot after their baby is born if their baby is Rh-positive.
RhoGAM is made of antibodies. If not, you are Rh-negative, a trait shared by 15 percent of the US population. When a gestational carrier who is Rh-negative receives a RhoGAM shot, she is preventing her blood system from potentially attacking the fetal blood. There are two aspects to consider in potential differences between the surrogate and the infant's blood systems:. If the gestational carrier is Rh-negative, but the baby is Rh-positive, she could develop antibodies that attack and destroy Rh-positive blood.
This may cause fetal anemia, which can develop into hydrops fetalis, a condition that leads to internal bleeding, shock, and heart and kidney failure. Before the development of the RhoGAM medicine in the s, this condition alone led to the death of about 10, newborns annually and brain damage in others. The risk of fetal harm increases from one pregnancy to any future Rh-positive fetuses in subsequent pregnancies. In fact, if you are Rh-negative, your doctor will likely suggest you have a RhoGAM shot after a miscarriage , especially in the first trimester, within 72 hours.
This will help prevent the antibodies from circulating any further and reduce future risks. A RhoGAM shot acts almost as a vaccination , which introduces the body to a dosage of a virus that is too small to cause serious illness.
Thus, the body learns to fight the virus effectively and prevents major reaction or sickness if exposed later which is called Rh sensitization. In this case, a RhoGAM shot contains antibodies to Rh-positive blood, but not in a high enough amount that it will hurt the fetus. When the gestational carrier's body detects antibodies from an infant's Rh-positive blood, which can happen especially during delivery, her immune system reacts as if it has already fought the foreign Rh-positive red blood cells.
