Description

The aim of our study is to perform a phase 1, single arm clinical trial to investigate the distribution of rivaroxaban into human milk at both therapeutic and prophylactic maternal doses. Our goal is to enhance the limited, although positive, data regarding the safety of rivaroxaban in breastfeeding. Our novel contributions to the existing body of literature will be in our investigation of rivaroxaban at both prophylactic and therapeutic doses, in repeated doses over time, and in a larger sample of participants. These results will provide physicians and national societies with safety data needed to properly counsel patients and advance clinical guidelines for postpartum care.
