Summary
Ethiodized oil is an iodinated contrast agent used in lymphography and hepatic embolization. Contrast-related kidney injury or systemic exposure could impair metformin clearance and raise the risk of lactic acidosis.
What this interaction means in plain words
Ethiodized oil and Metformin-sitagliptin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Potential contrast-associated renal impairment reduces metformin elimination, leading to accumulation and lactic acidosis.
What to do
Withhold metformin around the procedure in patients with eGFR below 30, acute kidney injury, or intra-arterial administration. Restart after 48 hours once renal function is stable.
