糖尿病病人若服用 Metformin，在使用顯影劑前必須停藥至少 48 小時，以避免顯影劑誘發急性腎衰竭與 Metformin 導致的乳酸中毒。評估過敏史也很重要，但藥物互動是醫囑遵從性的關鍵生命安全議題。
Metformin must be withheld for 48 hours before and after procedures involving iodinated contrast dye to prevent acute kidney injury-induced lactic acidosis. While assessing for allergies is important, preventing this life-threatening metabolic complication takes priority in patient safety.
