What the FDA labels say
From the Exenatide (Byetta) label · effective 2025-09-02
• Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin: Patients taking an insulin secretagogue or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.
Reduction in the dose of insulin secretagogues or insulin may be necessary.
If there is worsening glycemic control or failure to achieve target glycemic control, consider alternative antidiabetic therapy.
Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin Patients receiving BYETTA 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) 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.
From the Insulin detemir (Levemir) label · effective 2024-10-09
For patients with type 2 diabetes, dosage adjustments of concomitant antidiabetic products may be needed [see Dosage and Administration ( 2.4 )].
The risk of hypoglycemia after an injection is related to the duration of action of the insulin [see Clinical Pharmacology ( 12.2 )] and, in general, is highest when the glucose lowering effect of the insulin is maximal.
When a GLP-1 receptor agonist is used in combination with LEVEMIR, the LEVEMIR dose may need to be lowered or more conservatively titrated to minimize the risk of hypoglycemia [see Adverse Reactions ( 6.1 )] .
…May Increase the Risk of Hypoglycemia Drugs: Antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, salicylates, somatostatin analogs (e.g., octreotide), and sulfonamide antibiotics, GLP-1 receptor agonists, DPP-4 inhibitors, SGLT-2 inhibitors.
Drugs That May Decrease the Blood Glucose Lowering Effect of LEVEMIR Drugs: Atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol,…
