What the FDA labels say
From the Glipizide and metformin (Glipizide and Metformin Hydrochloride) label · effective 2026-06-27
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 Linagliptin (Tradjenta) label · effective 2025-03-21
Hypoglycemia: Consider lowering the dosage of insulin secretagogue or insulin to reduce the risk of hypoglycemia when initiating TRADJENTA ( 5.2 )
Hypoglycemia with Concomitant Use with Insulin and Insulin Secretagogues Insulin secretagogues and insulin are known to cause hypoglycemia.
The risk of hypoglycemia is increased when TRADJENTA is used in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin [see Adverse Reactions (6.1) ] .
Therefore, a lower dosage of the insulin secretagogue or insulin may be required to reduce the risk of hypoglycemia when used in combination with TRADJENTA.
Insulin Secretagogues or Insulin Insulin and insulin secretagogues are known to cause hypoglycemia.
