The injectable low molecular weight heparins (LMWH; e.g. enoxaparin = Lovenox; dalteparin = Fragmin; tinzaparin = Innohep) are the preferred blood thinners in the pregnant patient. Warfarin is to be avoided as it can cause malformations of the fetus and can lead to bleeding in the unborn.
Regarding breastfeeding: the low molecular weight heparins (listed above) and warfarin are safe in the woman who is beastfeeding.
Rivaroxaban (Xarelto), dabigatran (Pradaxa) and apixaban (Eliquis) should not be used during pregnancy or while breastfeeding.
A detailed summary about the safety of each blood thinner during pregnancy and while breast-feeding, based on the ACCP 2012 guidelines [ref], can be found here.
