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.
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.
A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported.
From the Saxagliptin label · effective 2026-01-27
• Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues: Consider a lower dosage of insulin or insulin secretagogue when used in combination wtih Saxagliptin tablets ( 5.3 )
Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues When saxagliptin was used in combination with insulin or an insulin secretagogue, the incidence of confirmed hypoglycemia was increased over that of placebo used in combination with insulin or an insulin secretagogue [ see Adverse Reactions (6.1) ].
Therefore, a lower dosage of insulin or an insulin secretagogue may be required to reduce the risk of hypoglycemia when used in combination with saxagliptin [ see Drug Interactions (7.2)].
Insulin or Insulin Secretagogues Insulin and insulin secretagogues are known to cause hypoglycemia.
Concomitant use of saxagliptin tablets with insulin or an insulin secretagogue may require lower dosages of insulin or the insulin secretagogue to reduce the risk of hypoglycemia [see Warnings and Precautions (5.3)].
