Inositol and Insulin Glargine, a caution.
Myo-inositol and D-chiro-inositol improve insulin sensitivity and can lower fasting glucose. Insulin glargine provides 24-hour basal insulin coverage. Combined, the additive glucose-lowering can produce nocturnal hypoglycemia, particularly during the first weeks after starting inositol.

Caution
What is happening. Myo-inositol and D-chiro-inositol improve insulin sensitivity and can lower fasting glucose. Insulin glargine provides 24-hour basal insulin coverage. Combined, the additive glucose-lowering can produce nocturnal hypoglycemia, particularly during the first weeks after starting inositol.
Mechanism. Inositol phosphoglycan second messengers improve insulin receptor signaling and GLUT4-mediated glucose uptake in skeletal muscle. Insulin glargine binds the insulin receptor to drive cellular glucose uptake and suppress hepatic glucose output. The two are additive.
Recommendation. Tell your prescriber before starting inositol on insulin glargine. Check fasting and bedtime glucose more often for the first 2-4 weeks and discuss whether your glargine dose should be reduced.
