Understanding Rohgam and Miscarriage Risk

Question
My cousin went into the hospital to be looked at because she was just under 14 weeks pregnant and having cramping in her obdominal area so to be safe she went in too make sure everything was okay. Well the doctor check her and did a ultra-sound and said they fetus was in tack and it looked good. well then the nurse came in and said she need this shot called rohgam well she was released shortly after that and when she was at home a couple hours later she started to bleed and miscarried. I was under the impression that one that shot wasn't to be given until 28 weeks if needed not just under 14 weeks pregnant and could this have been the reason why she miscarried??? Need closure on this very upsetting situation.

Answer
Dear Chev,

The RhoGAM injection for Rh incompatibility is typically given around 28 weeks. That is because the effects of the shot last for only about 12 weeks. Thus, the injection should last through the time that the woman delivers (40 weeks), at which time another injection is usually given if the baby is Rh positive. Therefore, although your cousin would have needed a repeat injection at the "normal" time of 28 weeks, I can find no other research to indicate it would be a threat to the pregnancy. However - if she has serious reservations as to why this was done and the possible correlation to the miscarriage, she really should speak to her OB doctor directly about it.

I hope this has helped you and answered your question. I am sorry to hear of the loss and wish you both well.
