Drug Name		Reteplase				Salicylic acid (sodium)
Mechanism		Risk of bleeding Thrombolytic agent				Risk of bleeding Antiplatelet effects
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 Reteplase and Salicylic acid (sodium)

Recommended Action
Management		Careful monitoring for signs of bleeding, particularly at arterial puncture wounds, is recommended when thrombolytics are used concurrently or sequentially with antiplatelet agents other than aspirin. Some authorities recommend avoiding the initiation of platelet aggregation inhibitors within the first 24 hours following thrombolysis treatment.
