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 Dulaglutide (Trulicity) label · effective 2026-06-16
Hypoglycemia: Concomitant use with an insulin secretagogue or insulin may increase the risk of hypoglycemia, including severe hypoglycemia.
Reducing the dose of insulin secretagogue or insulin may be necessary ( 5.3 ).
Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin Patients receiving TRULICITY in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia [see Adverse Reactions ( 6.1 ) and Drug Interactions ( 7 )].
The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin.
Concomitant Use with an Insulin Secretagogue (e.g., Sulfonylurea) or with Insulin When initiating TRULICITY, consider reducing the dose of concomitantly administered insulin secretagogues (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia [see Warnings and Precautions ( 5.3 ) and Adverse Reactions ( 6.1 )].
