What are the recommendations for pregnant women using anticoagulants?
For pregnant women, we suggest avoiding the use of NOACs (Ungraded consensus-based statement). For women on treatment with long-term vitamin K antagonists who are attempting pregnancy and are candidates for LMWH substitution, we suggest performing frequent pregnancy tests and use LMWH instead of VKA when pregnancy is achieved rather than switching to LMWH while attempting pregnancy (Ungraded consensus-based statement). For lactating women using warfarin, acenocoumarol, or UFH who wish to breast-feed, we suggest continuing the use of warfarin, acenocoumarol, LMWH, or UFH (Ungraded consensus-based statement). For breast-feeding women, we suggest alternative anticoagulants rather than NOACs (Ungraded consensus-based statement).
