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 Dexketoprofen interactions, 59 are rated major — including this one.

The Bottom Line
Taking amitriptyline with the NSAID dexketoprofen raises your bleeding risk, so watch for unusual bleeding or bruising and check with your pharmacist or doctor before combining them or adding other NSAIDs.

You've been prescribed amitriptyline (a tricyclic antidepressant) along with dexketoprofen (an anti-inflammatory pain reliever, a type of NSAID). When these two are taken together, they can raise your risk of bleeding. In rare cases this can include serious bleeding, such as bleeding in the brain.

The good news is that this is very manageable. Many people take medicines like these safely under a doctor's watch. Please keep taking both exactly as prescribed, and let your care team know right away if you notice things like unusual bruising, blood in your stool, dark or tarry stools, a bad headache, or any bleeding that won't stop. Your pharmacist or doctor can help you weigh the safest option.

Effect: Increased bleeding risk with concurrent tricyclic antidepressant (amitriptyline) and NSAID (dexketoprofen), including reports of intracranial hemorrhage within 30 days of combined use.

Direction/mechanism: Additive bleeding tendency; precise mechanism unknown. TCAs may impair platelet function and NSAIDs inhibit platelet aggregation plus cause GI mucosal injury. Neither agent's effect here depends on prodrug activation.

  • Severity: Major
  • Evidence: Established
  • Onset: Unspecified

Management: Use caution when coadministering. Monitor for signs of increased bleeding (GI bleeding, bruising, neurologic changes suggesting intracranial hemorrhage). Consider gastroprotection or alternative analgesia in higher-risk patients.

What happens

An increased risk of bleeding

Interaction Deep Dive

Exercise caution when NSAIDs are administered together with tricyclic antidepressants, since combining them may raise the likelihood of bleeding, such as intracranial hemorrhage occurring within 30 days of concurrent use1. During concomitant therapy with these two drug classes, watch the patient for indications of heightened bleeding.

Unknown

How to manage this interaction

This combination can be managed with care from your team. Keep taking both medicines as prescribed unless your prescriber tells you otherwise.

  • Your care team may monitor you more closely for signs of bleeding while you use both.
  • They may consider a different pain reliever or add stomach protection, especially if you have other bleeding risks (older age, ulcers, blood thinners, alcohol use).
  • Watch for warning signs: black or tarry stools, blood in vomit or urine, unusual bruising, a sudden severe headache, weakness, or trouble speaking, and get help right away for these.

Ask your pharmacist or doctor before adding any over-the-counter NSAID like ibuprofen or naproxen.

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

Literature reports

1 report — tap to read

a) Combined use of NSAIDs with antidepressants, including tricyclic antidepressants, SSRIs, serotonin-norepinephrine reuptake inhibitors, and MAOIs, produced a heightened risk of intracranial hemorrhage within 30 days of concurrent use when compared with antidepressant use by itself. No significant difference was observed between the antidepressant drug classes with respect to the elevated risk; nonetheless, an increased risk was associated with male patients relative to female patients 1.
