Summary

Both are NSAIDs, so taking them together duplicates therapy without added benefit. The combination increases the risk of gastrointestinal ulceration and bleeding, renal injury and hyperkalemia.

What this interaction means in plain words

Meclofenamate and Oxaprozin 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.

Evidence level: High

Why it happens

Additive cyclooxygenase inhibition affecting platelet function, gastric mucosal protection and renal prostaglandin-dependent perfusion.

What to do

Avoid concurrent use of two systemic NSAIDs and use a single agent at the lowest effective dose. Switch if one drug is being replaced by the other and stop the first.
