Summary
Iodinated contrast can cause acute kidney injury, which reduces metformin clearance and may lead to metformin accumulation and lactic acidosis. The risk is greatest with impaired renal function or intra-arterial administration.
What this interaction means in plain words
Canagliflozin-metformin and Diatrizoate meglumine / diatrizoate 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-induced renal impairment reduces metformin excretion, leading to accumulation.
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, and restart only after renal function is re-evaluated about 48 hours later.
What to ask your pharmacist
