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.
Celecoxib (Celebrex) is an anti-inflammatory pain reliever, and apixaban (Eliquis) is a blood thinner. When you take them together, they can each make bleeding more likely, so combining them raises that risk a bit more than either one alone.
This means you may bruise more easily or bleed a little longer. Watch for warning signs like unusual bruising, pink or red urine, black or bloody stools, nosebleeds that won't stop, or coughing or vomiting up something that looks like blood. The good news is your care team can manage this. Keep taking both exactly as prescribed and check in with your pharmacist or doctor so they can keep an eye on you.
Effect: Additive increase in bleeding risk when combining the NSAID celecoxib with the factor Xa inhibitor apixaban.
- Mechanism: Pharmacodynamic (additive) effect on hemostasis. Apixaban inhibits factor Xa; NSAIDs impair platelet function and can cause GI mucosal injury. Neither is a prodrug relevant here, so no PK reversal applies.
- Direction/magnitude: Increased bleeding risk vs. either agent alone; magnitude not quantified.
- Onset: Unspecified. Evidence: Theoretical.
- Management: Monitor for signs/symptoms of bleeding (GI, mucocutaneous, neurologic). Heightened caution with neuraxial anesthesia/spinal puncture given risk of spinal or epidural hematoma. Individualize therapy.
What happens
An increased risk of bleeding
Interaction Deep Dive
Taking an anticoagulant together with an NSAID can raise the likelihood of severe bleeding compared with either agent used by itself1234, and it may also heighten the chance of epidural or spinal hematomas capable of causing prolonged or permanent paralysis in individuals receiving neuraxial anesthesia or undergoing spinal puncture5. When these drugs are given at the same time, watch for signs of bleeding124.
Why it happens (mechanism)
Additive effect on hemostasis
How to manage this interaction
Keep taking both medications as prescribed unless your prescriber tells you otherwise. This combination can be used with care.
- Your care team may monitor you more closely for signs of bleeding.
- Watch for and report unusual bruising, nosebleeds, blood in urine or stool, black stools, or bleeding that won't stop.
- Tell your team right away if you are scheduled for a spinal procedure or epidural, since the combination raises the risk of a spinal blood clot (hematoma).
- Your dose or choice of pain reliever may need to be adjusted and individualized by your team.
Management is individual — confirm any change with your pharmacist or prescriber.
