Summary

Combining aspirin with piroxicam increases the risk of gastrointestinal ulceration and bleeding. Piroxicam may also interfere with the antiplatelet cardioprotective effect of low-dose aspirin, and the combination adds renal risk.

What this interaction means in plain words

Acetylsalicylic acid and Piroxicam can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Acetylsalicylic acid belongs to Musculoskeletal; Piroxicam belongs to Musculoskeletal.

Evidence level: High

Why it happens

Both inhibit COX-mediated gastroprotective prostaglandins and platelet function, and piroxicam may compete with aspirin at the COX-1 binding site.

What to do

Avoid routine combination; if aspirin is taken for cardioprotection, choose an alternative analgesic or add gastroprotection with a PPI. Monitor for GI bleeding and renal function.
