Lovenox Injections in Pregnancy

Some women like me, know before they ever get pregnant they will have to be on anticoagulation (blood thinning) therapy, like Lovenox injections during pregnancy. Others have never heard of it and can be scared when they think about having to give themselves injections every day. Lovenox can be prescribed for a variety of reasons. For me, it was a history of a DVT, deep vein thrombosis (blood clot) in my leg. My DVT was a postoperative complication of my spinal fusion surgery, but once you have had a clot, you are at risk to have another. So for me, that meant 546 injections in my stomach over 39 weeks to get my baby here as safely as possible. Factor V Leiden thrombophilia in pregnancy and history of some pregnancy losses or fertility treatments are also reasons a woman might be put on anticoagulation like Lovenox. Pregnancy increases a woman’s risk of blood clots and they can be detrimental if they travel to her heart, her brain, the baby’s placenta or the umbilical cord. Although it can be intimidating, if your obstetrician or midwife prescribes Lovenox or anticoagulation therapy, it is because the risk of a clot outweighs the risk of the medication in your pregnancy.
