How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
You've been prescribed Eliquis (apixaban), a blood thinner, along with tenoxicam, an anti-inflammatory pain medicine (an NSAID). Both of these can affect how your blood clots, but in different ways. When you take them together, that effect can add up, which may raise your chance of bleeding. This can show up as easy bruising, nosebleeds, bleeding gums, or, less often, more serious internal bleeding.
The good news is that this is very manageable. Please don't stop either medicine on your own. Just watch for any unusual bleeding or bruising and let your pharmacist or doctor know, and be sure they know you take both so they can keep an eye on things.
Effect: Additive risk of serious bleeding when apixaban (a direct factor Xa inhibitor) is combined with tenoxicam (an NSAID).
- Mechanism: Pharmacodynamic, additive impairment of hemostasis. Apixaban inhibits clotting; NSAIDs impair platelet function and can cause GI mucosal injury. Neither is a prodrug in a way that alters direction here.
- Direction/magnitude: Increased bleeding risk versus either agent alone; magnitude not quantified.
- Onset: Unspecified. Evidence: Theoretical, but clinically plausible and consistent with class labeling.
- Management: Monitor for signs/symptoms of bleeding. Heightened vigilance with neuraxial anesthesia or spinal puncture given epidural/spinal hematoma risk. Consider GI protection and reassess need for concurrent NSAID.
What happens
An increased risk of bleeding
Interaction Deep Dive
When an anticoagulant is given together with an NSAID, the likelihood of serious bleeding may rise compared with taking either agent by itself1234. In addition, this combination may heighten the chance of epidural or spinal hematomas, which can lead to prolonged or permanent paralysis, among patients receiving neuraxial anesthesia or undergoing spinal puncture5. Should the two drugs be used at the same time, watch for indications of bleeding124.
Why it happens (mechanism)
Additive effect on hemostasis
How to manage this interaction
Your care team can manage this safely. Typically they will:
- Keep monitoring you for signs of bleeding while you take both medicines.
- Decide whether the NSAID is truly needed, or whether a different pain option might be safer for you.
- Take extra care if you are having any procedure involving a spinal injection or spinal puncture, since combining these medicines raises the risk of a spinal blood clot (hematoma).
What you should do: Keep taking both as prescribed unless told otherwise. Watch for unusual bruising, nosebleeds, bleeding gums, pink or red urine, black or bloody stools, or vomit that looks like coffee grounds. Report these promptly, and always tell your pharmacist and doctor that you take both.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
