Chromium and Glimepiride, a caution.
Chromium improves insulin sensitivity, while glimepiride forces pancreatic insulin release. Combined, the additive effect on blood glucose can produce hypoglycemia, particularly in patients who skip meals, drink alcohol, or have reduced kidney function. The risk is highest in the first month after chromium is started or its dose is increased.

Caution
What is happening. Chromium improves insulin sensitivity, while glimepiride forces pancreatic insulin release. Combined, the additive effect on blood glucose can produce hypoglycemia, particularly in patients who skip meals, drink alcohol, or have reduced kidney function. The risk is highest in the first month after chromium is started or its dose is increased.
Mechanism. Chromium enhances insulin receptor tyrosine phosphorylation and GLUT4 translocation in skeletal muscle. Glimepiride binds the 65 kDa SURx subunit on pancreatic beta cells, closing K-ATP channels and driving insulin secretion. The combined glucose-lowering exceeds either drug alone.
Recommendation. Tell your prescriber before starting chromium on glimepiride. Monitor fingerstick glucose more often (before meals and at bedtime) for the first 2-4 weeks and ask whether the glimepiride dose should be reduced.
