Which finding would stop metformin therapy?
Answer and explanation
Correct answer: B. Estimated GFR below 30 mL/min
- Step 1: Metformin accumulates in renal failure.
- Step 2: This raises the risk of lactic acidosis.
Answer
Estimated GFR below 30 mL/min.
Why not the others: 'HbA1c of 7.5%' is a reason to adjust therapy, not stop it; 'BMI of 31' is not a contraindication; 'Mild peripheral neuropathy' is not a contraindication.
