Summary
Iodinated contrast agents can cause acute kidney injury, which reduces metformin clearance and may lead to lactic acidosis. Risk is highest with reduced eGFR or arterial administration, and ethiodized oil is often used in lymphography or hepatic procedures.
What this interaction means in plain words
Ethiodized oil and Metformin-repaglinide 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
Contrast-associated renal impairment reduces renal elimination of metformin, causing accumulation.
What to do
Withhold metformin around the procedure in at-risk patients and restart after renal function has been rechecked and found stable, typically at 48 hours.
