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 347 documented Meloxicam interactions, 279 are rated major — including this one.

What happens

An increased risk of bleeding, increased risk of gastrointestinal adverse events and reduced renal function

Interaction Deep Dive

Aspirin (low-dose or analgesic-dose) is generally not recommended with meloxicam due to an increased risk of bleeding and gastrointestinal adverse events23. Concurrent use of aspirin with meloxicam (an NSAID) may also lead to reduced renal function 1. Patients with asthma may have aspirin-sensitive asthma. Meloxicam is contraindicated in patients with aspirin-sensitive asthma, because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients. Monitor patients with preexisting asthma (without aspirin sensitivity) 3. In the setting of concomitant use of low-dose aspirin for cardiac Intervention: prophylaxis, monitor patients more closely for evidence of GI bleeding. Meloxicam is not a substitute for low dose aspirin for cardiovascular protection 4.

Why it happens (mechanism)

Additive effects on hemostasis; additive gastrointestinal adverse effects; unknown

Literature reports

2 reports — tap to read

a) Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone 4.

b) In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of gastrointestinal adverse reactions as compared to use of the NSAID alone. Also, when NSAIDs were administered with aspirin, the protein binding of NSAIDs were reduced, although the clearance of free NSAID was not altered. The clinical significance of this interaction is not known 43.
