Summary
Intravascular iopromide can cause acute kidney injury, and reduced renal function impairs metformin elimination. Metformin accumulation may lead to lactic acidosis, which is rare but life-threatening.
What this interaction means in plain words
Iopromide and Saxagliptin-metformin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Contrast-induced decline in renal function reduces metformin clearance, raising the risk of metformin accumulation and lactic acidosis.
What to do
Withhold metformin at the time of or before contrast in patients with eGFR below 30, acute kidney injury, or intra-arterial administration. Re-check renal function about 48 hours later and resume metformin only if it is stable.
