Does creatine interact with statins? Is it safe to take both?

Creatine and statins do not have a direct pharmacokinetic interaction, but both creatine supplementation and statin therapy independently can cause myalgias (muscle pain) and, in rare cases, elevated creatine kinase (CK), so men taking statins should inform their physician they also take creatine to ensure that any muscle symptoms or CK elevations are correctly attributed and not dismissed (Poortmans & Francaux, Sports Med, 2000).

Statin-induced myopathy (muscle damage) is rare but real, occurring in approximately 1–5% of statin users, more commonly at higher statin doses. Creatine supplementation increases baseline CK slightly by increasing muscle creatine stores and turnover. The concern is not that creatine causes statin myopathy, there is no evidence for this, but that if you develop statin myopathy, the elevated CK picture is more difficult to interpret when you are also taking creatine. The management is transparent communication with your physician.

Honesty Scale: Solid (1) for absence of direct pharmacokinetic interaction. Solid (1) for the need to communicate creatine use to your statin prescriber.

What to do: Tell your physician and pharmacist you take creatine alongside your statin. Request a baseline CK level before starting creatine (or at your next annual visit) so you have a reference point. Report any new muscle pain or weakness to your physician promptly, this applies whether you take creatine or not.
