Resumo
Iodinated contrast can cause acute kidney injury, which reduces metformin elimination and leads to accumulation. This increases the risk of metformin-associated lactic acidosis, especially in patients with reduced renal function.
O que esta interação significa em palavras simples
Canagliflozin-metformin and Contrast media 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.
Por que acontece
Contrast-induced reduction in renal function lowers renal clearance of metformin, causing accumulation.
O que fazer
Hold metformin at the time of or before the procedure in patients with eGFR 30-60, liver disease, alcoholism, heart failure, or intra-arterial contrast. Re-check renal function 48 hours afterward and restart only if it is stable.
