what is the importance of the rogaine shot after delivery for future pregnancies?

Question

for a mother with o negative blood.

Answer 1

It's actually called rhogam and it prevents complications in future pregnancies.

Answer 2

To be more precise, when a mother with a negative blood type has a baby with a positive blood type the baby's blood can cross over to her body which then builds anti-bodies for type positive blood. If she then becomes pregnant with another type positive baby her body can detect the new baby's blood, recognize it as an "invader" and use the anti-bodies from the previous pregnancy to attack the baby and kill it, causeing a miscarrige.

Rhogam prevents this. It's pretty much standard for any type negative mother to get one shot during and one shot after each pregnancy, regardless of the baby's blood type, just to be on the safe side.

There are no problems when a type positive mother has a type negative baby and Rhogam is not nessecary then.

Answer 3

I think you mean the Rhogam shot.

When you deliver a baby with a different Rh factor than you have, and blood gets intermingled, you can develop antibodies against the other Rh factor--harmful or deadly to a developing fetus. The shot keeps you from developing those antibodies, and protects future embryos.
