What is preferred for anticoagulation in pregnancy?

  1. Warfarin

  2. Aspirin

  3. LMWH

  4. NOACs

The correct answer is: LMWH

During pregnancy, LMWH (low molecular weight heparin) is generally preferred for anticoagulation over other options such as Warfarin, Aspirin, or NOACs (new oral anticoagulants). This is because LMWH has a lower risk of causing harm to the developing fetus and has a more predictable effect on blood clotting. Warfarin and NOACs can pass through the placenta and potentially cause birth defects, while Aspirin may increase the risk of bleeding in both the mother and baby. Therefore, it is important for pregnant women to discuss anticoagulation options with their healthcare provider in order to choose the safest and most effective option for their specific situation.
