Summary

Using two NSAIDs together increases the likelihood of gastrointestinal bleeding, ulceration and kidney injury without improving pain relief. Platelet inhibition from both drugs is additive.

What this interaction means in plain words

Ketoprofen and Tolmetin 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.

Ketoprofen belongs to Musculoskeletal; Tolmetin belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

Additive non-selective COX inhibition reduces protective prostaglandins in the gut and kidney and impairs platelet function.

What to do

Avoid combining the two; keep a single NSAID at the lowest effective dose. Add gastroprotection and monitor renal function if therapy overlap cannot be avoided.

What to ask your pharmacist

  • Does the benefit of taking both outweigh the risk in my case?
