What the FDA labels say
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.
From the Repaglinide label · effective 2025-05-02
Factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content), changes in level of physical activity, changes to co-administered medication [see Drug Interactions (7) ] , and concomitant use with other antidiabetic agents.
Drugs That May Decrease the Blood Glucose Lowering Effect of Repaglinide Tablets Intervention: Repaglinide tablets dose increases and increased frequency of glucose monitoring may be required when co-administered.
CYP2C8 and CYP3A4 Inducers and Drugs That May Decrease the Blood Glucose Lowering Effect of repaglinide tablets : Co-administration may require repaglinide tablets dose increases and increased frequency of glucose monitoring ( 7 )
Serious Cardiovascular Adverse Reactions with Concomitant NPH-insulin : Repaglinide tablets is not indicated for use in combination with NPH-insulin.
Serious Cardiovascular Adverse Reactions with Concomitant Use with NPH-insulin Across seven controlled trials, there were six serious adverse events of myocardial ischemia in patients treated with repaglinide tablets plus NPH-insulin from two studies, and one event in patients using insulin formulations alone from another study [See Adverse Reactions (6.1) ].
