Summary
Intravascular iodinated contrast can cause acute kidney injury, which reduces metformin clearance. Metformin accumulation can then precipitate lactic acidosis, a rare but serious complication.
What this interaction means in plain words
Diatrizoate meglumine / diatrizoate and Glipizide-metformin 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 acute kidney injury reduces renal elimination of metformin, leading to accumulation and lactic acidosis.
What to do
Hold metformin at the time of or before the procedure in patients with eGFR below 30, acute kidney injury or intra-arterial contrast with renal exposure. Restart about 48 hours later only after renal function has been re-checked and is stable.
