      Drug Name Argatroban Salicylic acid (sodium)
      Mechanism Risk of bleeding
Anticoagulant 
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 Argatroban and Salicylic acid (sodium) 

Recommended Action
      Management Until further data are available, products containing salicylates, especially if given chronically or in high dosages, should preferably be avoided in patients receiving anticoagulants. Close clinical and laboratory observation for bleeding complications is recommended if concurrent therapy is necessary. The same precaution should be observed with the use of salicylate-related agents such as salicylamide because of their structural and pharmacological similarities.
