Drugs with the highest degree of serotonin reuptake inhibition—fluoxetine, paroxetine, and sertraline—are more frequently associated with altered anticoagulant effects; thus concomitant use of nonsteroidal anti-inflammator drugs (NSAIDs), aspirin, warfarin, or other drugs that affect coagulation potentiates the risk of bleeding.
