Background: Oral anticoagulants (OAC) may exacerbate menstrual bleeding in women of childbearing age; however, the existing literature on this issue has several limitations.
Materials And Methods: This study investigates abnormal uterine bleeding in women of childbearing age taking OAC-vitamin K antagonists or direct oral anticoagulants-for venous thromboembolism through a retrospective analysis of prospectively collected data. Uterine bleeding was assessed using the Pictorial Blood Assessment Chart (PBAC) and hemoglobin (Hb) values during anticoagulation compared with prior therapy.
