Which medication is a common anticoagulant administered during pregnancy?

Heparin is a common anticoagulant administered during pregnancy due to its safety profile and mechanism of action. Unlike oral anticoagulants, heparin does not cross the placenta, which eliminates the risk of fetal exposure and associated complications. It is often used to prevent and treat thromboembolic events in pregnant women, especially in those with a history of clotting disorders or conditions that predispose to thrombosis.

During pregnancy, managing the risk of blood clots is crucial, and heparin's ability to work effectively while minimizing risks to the developing fetus makes it an ideal choice. Heparin is available in two forms: unfractionated heparin and low molecular weight heparin (LMWH), the latter of which is commonly used due to its ease of use and predictable dosing.

While other anticoagulants like warfarin and direct oral anticoagulants such as apixaban are effective in non-pregnant populations, they pose more significant risks during pregnancy, including the potential for teratogenic effects and complications for the fetus. Enoxaparin, being a type of low molecular weight heparin, is also used in pregnancy, but it is less commonly highlighted compared to standard heparin. Overall,
