What the FDA labels say
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 )].
From the Insulin lispro (LYUMJEV) label · effective 2026-06-16
Increase frequency of glucose monitoring with changes to: insulin dosage, co-administered glucose lowering medications, meal pattern, physical activity; and in patients with renal impairment or hepatic impairment or hypoglycemia unawareness.
Risk Factors for Hypoglycemia The risk of hypoglycemia after an injection is related to the duration of action of the insulin and, in general, is highest when the glucose lowering effect of the insulin is maximal.
Clinically Significant Drug Interactions with LYUMJEV Drugs That 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.
Drugs That May Decrease the Blood Glucose Lowering Effect of LYUMJEV 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,…
Drugs That May Increase or Decrease the Blood Glucose Lowering Effect of LYUMJEV Drugs: Alcohol, beta-blockers, clonidine, and lithium salts.
