Menorrhagia is a common complication to oral anticoagulant therapy in premenopausal women. Clinical management of menorrhagia poses a clinical dilemma with the need of weighting bleeding risk against the risk of recurrent thrombosis. In this review, we describe the risk of menorrhagia during oral anticoagulant therapy, with emphasis on the differences between the specific anticoagulant drugs. We critically assess the treatment options for anticoagulant-associated menorrhagia, and we provide a treatment algorithm for the management of anticoagulant-associated menorrhagia.
