The risk of hypoglycemia is increased when caloric intake is deficient, when strenuous exercise is not compensated by caloric supplementation, or during concomitant use with other glucose-lowering agents or ethanol.
Macrovascular Outcomes There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with glipizide and metformin hydrochloride or any other antidiabetic drug.
From the Glyburide label · effective 2021-07-01
Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure.
A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported.
This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in patients with non-insulin-dependent diabetes.
