Summary

Creatine supplementation can raise serum creatinine and has been theorized to stress the kidneys, and NSAIDs reduce renal blood flow. Combined use might add to renal risk, though evidence is theoretical.

What this interaction means in plain words

Creatine and Diclofenac have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Evidence level: Low

Why it happens

Theoretical additive renal stress; NSAID prostaglandin inhibition plus creatine effects on renal function markers.

What to do

Monitor serum creatinine and hydration in patients using both, interpreting creatinine rises with the supplement in mind. Avoid the combination in existing kidney disease.
