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.
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.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
