Summary

ACE inhibitors may modestly improve glycemic control and occasionally increase hypoglycemia risk when used with antidiabetic drugs, though metformin alone rarely causes hypoglycemia. Acute kidney injury from an ACE inhibitor could indirectly reduce metformin clearance and raise lactic acidosis risk.

What this interaction means in plain words

Benazepril and Metformin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Benazepril belongs to Cardiovascular; Metformin belongs to Endocrine.

Evidence level: Low

Why it happens

Possible improved insulin sensitivity; renal impairment related to ACE inhibition could reduce metformin elimination.

What to do

Monitor blood glucose and renal function periodically. Hold metformin if acute kidney injury or dehydration develops.
