For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Diflunisal can reduce renal prostaglandin-mediated perfusion, and creatine supplementation has been theorized to add renal stress. The combined risk of kidney injury is theoretical and poorly documented.

What this interaction means in plain words

Creatine and Diflunisal 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

Additive renal effects are postulated, with NSAID-induced reduction in renal blood flow plus possible creatine renal burden; not well established.

What to do

Monitor serum creatinine in patients with existing kidney disease or dehydration who use both, and stop creatine if renal function worsens.

What to ask your pharmacist

  • Is there anything I should notice while taking both?
