Drugs that Interfere with Hemostasis (e.g. warfarin, aspirin, selective serotonin reuptake inhibitors [SSRIs]/serotonin norepinephrine reuptake inhibitors [SNRIs]): Monitor patients for bleeding who are concomitantly taking Piroxicam Capsules with drugs that interfere with hemostasis.

Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, antiplatelet drugs (such as aspirin), anticoagulants, or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older age; and poor general health status.

Co-morbid conditions such as coagulation disorders, concomitant use of warfarin, other anticoagulants, antiplatelet drugs (e.g., aspirin), SSRIs, and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk.

Table 1: Clinically Significant Drug Interactions with Piroxicam Drugs That Interfere with Hemostasis Clinical Impact: • Piroxicam and anticoagulants such as warfarin have a synergistic effect on bleeding.

The concomitant use of piroxicam and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone.
