Antiplatelet 
      Key Mechanism Factor 1
Factor Name Bleeding
Factor Description Patients may be at risk for bleeding when the outcome of a disease or disease treatment confounds the standard mechanisms for maintaining hemostasis. Signs or symptoms of abnormal bleeding include: bleeding that takes a long time to stop (including nosebleeds, bleeding gums, bleeding from cuts and abrasions, and menstrual bleeding); severe unexplained bruising, or bruising that becomes larger; blood in the urine or stool, etc.
      Mechanism Description
  • Increased risk of bleeding by the combination of Eptifibatide and Dipyridamole 

Recommended Action
      Management Extraordinary precautions are recommended if these drugs must be used together, including monitoring platelet counts and hemoglobin concentrations. In addition, invasive procedures, such as urinary catheterization, nasogastric or nasotracheal intubation, and even venous punctures should be avoided or minimized. Non-compressible venous access sites, such as jugular or subclavian sites, should be avoided.
