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.
…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 Insulin Degludec 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.,…
Drugs That May Increase or Decrease the Blood Glucose Lowering Effect of Insulin Degludec Drugs: Alcohol, beta-blockers, clonidine, and lithium salts.
As with all insulins, the glucose lowering effect time course of Insulin Degludec may vary among different patients or at different times in the same patients and depends on many conditions, including the area of injection as well as the injection site blood supply and temperature.
From the Liraglutide label · effective 2026-01-30
• Hypoglycemia : Adult patients taking an insulin secretagogue or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.
In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher with liraglutide regardless of insulin and/or metformin use.
Reduction in the dose of insulin secretagogues or insulin may be necessary.
Hypoglycemia Adult patients receiving liraglutide in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.
The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogues) or insulin.
