Avoid concurrent use. If NSAID therapy is necessary, consult your physician before continuing creatine supplementation. Monitor renal function regularly.
Why this interaction occurs
Creatine increases serum creatinine as a metabolic byproduct, which can mask declining renal function. NSAIDs reduce renal prostaglandin synthesis and decrease glomerular filtration rate. Combined use amplifies nephrotoxic burden, particularly during exercise-induced dehydration when renal perfusion is already compromised.
Evidence
Evidence level: moderate.
Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 1,051 reports mentioning Creatine. This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Creatine + supplement combination on this page.
FAERS reports are voluntary and cannot prove that a drug caused an event. Do not use report counts to assess the safety of this specific drug-supplement pair.
