Very Low Risk for breastfeeding

Safe. Compatible.
Not risky for breastfeeding or infant.

Direct factor Xa inhibitor, indicated in the prevention of thromboembolism.
Administered orally every 12 to 24 hours.

Its pharmacokinetic data (large volume of distribution and high percentage of protein binding) explain the very small passage to milk observed in four different cases (Saito 2019, Muysson 2019, Wiesen 2016). No problems were observed in an 18-month-old infant whose mother was treated with rivaroxaban from the first postpartum week (Saito 2019).

Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in case of prematurity.
