Summary

ACE inhibitors may slightly improve glucose control and reduce metformin requirements, and any acute renal impairment they cause can reduce metformin clearance. This raises a small risk of hypoglycemia with other agents and of lactic acidosis if renal function falls.

What this interaction means in plain words

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

Metformin belongs to Endocrine; Perindopril belongs to Cardiovascular.

Evidence level: Low

Why it happens

Improved insulin sensitivity and possible ACE inhibitor-related fall in renal function reducing metformin elimination.

What to do

Monitor renal function and glucose after starting perindopril. Hold metformin during acute illness with dehydration or declining renal function.
