OBG · Postpartum haemorrhage and emergencies: anticoagulant in lactation
Sample itemA breastfeeding woman who developed a deep vein thrombosis after delivery needs long-term oral anticoagulation. Which drug is acceptable?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Warfarin
Warfarin does not pass into breast milk in significant amounts and is considered compatible with breastfeeding. Heparins are also safe. Direct oral anticoagulants lack safety data in lactation and are generally avoided.
Option by option
A. Dabigatran
Dabigatran is a direct oral anticoagulant and is avoided during lactation.
B. Apixaban
Apixaban is a direct oral anticoagulant and is avoided during lactation for lack of safety data.
C. Warfarin (correct)
Correct. Warfarin is compatible with breastfeeding.
D. Rivaroxaban
Rivaroxaban is a direct oral anticoagulant and is avoided during lactation.
