Glipizide and Inositol, a caution.
Myo-inositol and D-chiro-inositol improve insulin sensitivity and lower fasting glucose. Glipizide forces pancreatic insulin secretion. Combined, the additive glucose-lowering can produce hypoglycemia, particularly in older adults or after missed meals.

Caution
What is happening. Myo-inositol and D-chiro-inositol improve insulin sensitivity and lower fasting glucose. Glipizide forces pancreatic insulin secretion. Combined, the additive glucose-lowering can produce hypoglycemia, particularly in older adults or after missed meals.
Mechanism. Inositol phosphoglycan second messengers improve insulin receptor signaling and peripheral glucose uptake. Glipizide closes K-ATP channels on pancreatic beta cells, forcing insulin secretion. The two mechanisms are additive.
Recommendation. Tell your prescriber before starting inositol on glipizide. Monitor fingerstick glucose more often during the first 2-4 weeks and ask whether the glipizide dose should be reduced.
