		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 Bivalirudin and Dipyridamole

Recommended Action
Management		Until further data are available, the coadministration of bivalirudin and antiplatelet agents, and possibly other agents with antiplatelet activity such as nonsteroidal anti-inflammatory drugs (NSAIDs), should probably be undertaken with caution. Close clinical and laboratory observation for bleeding complications is recommended.
