Can you take Creatine with Tenofovir disoproxil / emtricitabine?
This is general information, not medical advice. Supplements can interact with medicines and health conditions. Always check with your doctor or pharmacist before starting or changing supplements.
What the evidence says
Tenofovir disoproxil can harm the kidneys, so clinicians monitor it with regular creatinine-based eGFR tests. Creatine does not add to that kidney risk in healthy users — controlled trials and a meta-analysis show no true decline in renal function — but it reliably raises serum creatinine, because supplemental creatine degrades to creatinine. In a 28-day trial, creatine raised serum creatinine by roughly 0.1-0.2 mg/dL, dose-dependently, in people with normal kidneys; a 3-month randomised trial found creatinine unchanged or elevated while cystatin C, a creatine-independent kidney marker, showed kidney function was actually fine. On tenofovir, that artificial creatinine bump can mimic early drug nephrotoxicity, triggering unnecessary investigations or treatment changes — or muddy the picture if real kidney injury develops. Tell your HIV clinician before starting creatine, get a baseline creatinine first, and ask whether cystatin C-based monitoring is appropriate. Do not start or stop creatine silently around monitoring visits.
