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.

Of 91 documented Morniflumate interactions, 59 are rated major — including this one.

The Bottom Line
Combining apixaban (Eliquis) with the NSAID morniflumate can add up to raise your bleeding risk, so don't stop either on your own but do ask your pharmacist or doctor to monitor you and watch for any signs of bleeding.

Taking these two together can raise your risk of bleeding. Apixaban (Eliquis) is a blood thinner, and morniflumate is an anti-inflammatory pain reliever (an NSAID). Each one alone can make bleeding a little easier. When you use them together, that effect can add up, so bruising, nosebleeds, or more serious bleeding become more likely.

The good news is this is very manageable. Please don't stop either medicine on your own. Talk with your pharmacist or doctor so they can decide the safest plan for you and watch you a bit more closely. Let them know right away if you notice unusual bruising, blood in your urine or stool, black stools, or bleeding that won't stop.

Effect: Additive bleeding risk when a factor Xa inhibitor (apixaban) is combined with an NSAID (morniflumate). Neither drug is a prodrug; this is a pharmacodynamic interaction, not a metabolic one.

Mechanism: Additive impairment of hemostasis. Apixaban inhibits factor Xa; NSAIDs impair platelet function and can cause GI mucosal injury.

  • Direction: increased bleeding risk (increased drug effect on hemostasis).
  • Evidence: theoretical; severity rated major.
  • Onset: unspecified.
  • Management: monitor for signs/symptoms of bleeding; heightened caution with neuraxial anesthesia or spinal puncture due to risk of spinal/epidural hematoma.

What happens

An increased risk of bleeding

Interaction Deep Dive

Taking an anticoagulant together with an NSAID can raise the likelihood of serious bleeding compared with either agent used by itself1234, and in patients receiving neuraxial anesthesia or undergoing spinal puncture it can heighten the risk of epidural or spinal hematomas, which may lead to prolonged or permanent paralysis 5. When the two are given concurrently, watch for signs of bleeding 124.

Why it happens (mechanism)

Additive effect on hemostasis

How to manage this interaction

Keep taking both exactly as prescribed unless your care team tells you otherwise. This combination is usually manageable with closer attention.

  • Your team may monitor you more closely for signs of bleeding, and your treatment may be adjusted and individualized to keep you safe.
  • Watch for unusual bruising, nosebleeds, bleeding gums, pink or red urine, black or bloody stools, or coughing/vomiting blood, and report these promptly.
  • Tell any provider you take both drugs, especially before spinal procedures, epidurals, or surgery, because of a rare risk of spinal bleeding.

Ask your pharmacist before adding any other pain reliever, since many are also NSAIDs.

Management is individual — confirm any change with your pharmacist or prescriber.
