Berberine and Glyburide, a caution.
Glyburide is a potent sulfonylurea with high hypoglycemia risk. Adding berberine's AMPK-mediated glucose lowering significantly increases this risk.

Caution
What is happening. Glyburide is a potent sulfonylurea with high hypoglycemia risk. Adding berberine's AMPK-mediated glucose lowering significantly increases this risk.
Mechanism. Glyburide stimulates prolonged insulin secretion via KATP channel blockade. Berberine independently lowers glucose via AMPK activation. The combination can cause severe hypoglycemia.
Recommendation. Use extreme caution. Glyburide already has the highest hypoglycemia risk among sulfonylureas. Berberine should only be added with close medical supervision and glucose monitoring.
