Summary
Fibrates may enhance the glucose-lowering effect of sulfonylureas, and hypoglycemia has been reported when they are combined. Improved insulin sensitivity may contribute. Patients with low albumin or renal impairment are at higher risk.
What this interaction means in plain words
Fenofibric acid and Glimepiride can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Fenofibric acid belongs to Cardiovascular; Glimepiride belongs to Endocrine.
Why it happens
Possible displacement from plasma protein binding combined with additive glucose-lowering pharmacodynamic effects; the evidence for each component is limited.
What to do
Monitor blood glucose more frequently when fenofibric acid is started or stopped in a patient taking glimepiride. Reduce the sulfonylurea dose if hypoglycemia occurs.
