MONITOR CLOSELY: Concomitant use of vorapaxar with other agents that affect hemostasis such as anticoagulants, platelet inhibitors, thrombin inhibitors, thrombolytic agents, dextran, nonsteroidal anti-inflammatory agents (chronic), or agents that commonly cause thrombocytopenia may increase the risk of bleeding.
