Study Notes
Metformin and CT Scans
- Metformin is a biguanide oral antidiabetic medication, used as first-line treatment for type 2 diabetes.
- Metformin does not directly lower blood glucose. It works by decreasing glucose production in the liver and increasing tissue responsiveness to insulin.
- Combining metformin with IV contrast material during a CT scan increases the risk of renal toxicity and life-threatening lactic acidosis.
- Therefore, metformin should be held 1-2 days before a CT scan with contrast and for 48 hours afterwards.
