Summary

Taking two NSAIDs together adds no therapeutic benefit and increases the risk of gastrointestinal ulceration and bleeding, kidney injury and cardiovascular events. Platelet inhibition is additive as well.

What this interaction means in plain words

Ketoprofen and Meclofenamic acid 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; Meclofenamic acid belongs to Musculoskeletal.

Evidence level: High

Why it happens

Duplicate cyclooxygenase inhibition causes additive loss of protective prostaglandins in the gastric mucosa and kidney and additive platelet dysfunction.

What to do

Avoid concurrent use of two systemic NSAIDs and choose a single agent at the lowest effective dose. If a switch is made, stop the first NSAID before starting the second.
