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.
Apixaban (Eliquis) is a blood thinner, and diclofenac is an anti-inflammatory painkiller (an NSAID). When you take them together, they both make it a little harder for your blood to clot, so your chance of bleeding goes up. That can show up as easy bruising, nosebleeds, or something more serious like stomach bleeding.
This is a known caution rather than something proven to happen in everyone, but it is worth taking seriously. Please don't stop either medicine on your own. Talk with your pharmacist or doctor. They can look at whether a different pain option is better for you and can help you watch for any warning signs. This is very manageable when your care team is in the loop.
Effect: Additive bleeding risk with concomitant apixaban (direct factor Xa inhibitor) and diclofenac (NSAID). Neither is a prodrug; the interaction is pharmacodynamic, not metabolic.
- Mechanism: Additive impairment of hemostasis (anticoagulation plus NSAID effects on platelet function and GI mucosa).
- Direction: Increased bleeding risk versus either agent alone.
- Evidence: Theoretical; severity rated major. Onset unspecified.
- Management: Monitor for signs/symptoms of bleeding (GI bleed, bruising, hematuria, drop in Hgb/Hct). Heightened caution with neuraxial anesthesia or spinal puncture given risk of epidural/spinal hematoma. Consider alternative analgesia (e.g., acetaminophen) where appropriate.
What happens
An increased risk of bleeding
Interaction Deep Dive
Using an anticoagulant together with an NSAID can raise the likelihood of significant bleeding compared with taking either agent by itself1234, and it can also heighten the chance of epidural or spinal hematomas capable of causing prolonged or permanent paralysis in individuals receiving neuraxial anesthesia or undergoing spinal puncture 5. When these drugs are given at the same time, watch for indications of bleeding 124.
Why it happens (mechanism)
Additive effect on hemostasis
How to manage this interaction
The main concern here is additive bleeding risk, so care teams typically focus on caution and monitoring rather than a set dose change.
- Keep taking both exactly as prescribed unless your prescriber tells you otherwise.
- Your team may watch you more closely for bleeding and may consider a different pain reliever (such as acetaminophen) if that fits your situation.
- Watch for unusual bruising, black or bloody stools, pink/red urine, prolonged bleeding, or unexpected fatigue or dizziness, and report these.
- Tell any provider about both drugs before spinal or epidural procedures, since these carry a special bleeding risk.
Management is individual — confirm any change with your pharmacist or prescriber.
