…risk of developing epidural or spinal hematomas in these patients include: • use of indwelling epidural catheters • concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, or other anticoagulants • a history of traumatic or repeated epidural or spinal puncture • a history of spinal deformity…

The risk of these events may be higher with post-operative use of indwelling epidural catheters or concomitant use of other drugs affecting hemostasis such as NSAIDs [see Boxed Warning ] .

In clinical studies performed with fondaparinux sodium, the concomitant use of oral anticoagulants (warfarin sodium), platelet inhibitors (acetylsalicylic acid), NSAIDs (piroxicam), and digoxin did not significantly affect the pharmacokinetics/pharmacodynamics of fondaparinux sodium.

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 or concomitant use of warfarin, other anticoagulants, antiplatelet drugs (e.g., aspirin), SSRIs, and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk.

Table 2: Clinically Significant Drug Interactions with Oxaprozin Drugs That Interfere with Hemostasis Clinical Impact: Oxaprozin and anticoagulants such as warfarin have a synergistic effect on bleeding.

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

Intervention: Monitor patients with concomitant use of OXAPROZIN CAPSULES with anticoagulants (e.g., warfarin), antiplatelet drugs (e.g., aspirin), SSRIs, and SNRIs for signs of bleeding [see WARNINGS AND PRECAUTIONS (5.12) ].
