Hint : 📌Contrast + Metformin = Risk

Correct Answers:

  • “I took my metformin this morning.”.


Rationale :

🔷 Metformin must be held before PCI due to the use of contrast dye, which may cause renal impairment.

🔷 The combination of iodine-based contrast and metformin can result in lactic acidosis, a potentially life-threatening condition.

🔷 The provider needs to be informed immediately so that metformin can be discontinued 24–48 hours pre-procedure.

🔷 The contrast can accumulate if renal clearance is reduced, increasing toxicity.

🔷 Monitoring renal function (e.g., BUN, creatinine) is essential before and after the PCI when metformin is involved.
