Insulin glargine

Table 8 includes clinically significant drug interactions with LANTUS. Table 8: Clinically Significant Drug Interactions with LANTUS 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), sulfonamide antibiotics. GLP-1 receptor agonists, DPP-4 inhibitors, and SGLT-2 inhibitors. Intervention : Dosage reductions and increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs.

Drugs that May Decrease the Blood Glucose Lowering Effect of LANTUS 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, epinephrine, terbutaline), and thyroid hormones. Intervention : Dosage increases and increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that May Increase or Decrease the Blood Glucose Lowering Effect of LANTUS Drugs : Alcohol, beta-blockers, clonidine, and lithium salts.

Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Intervention : Dosage adjustment and increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that May Blunt Signs and Symptoms of Hypoglycemia Drugs : Beta-blockers, clonidine, guanethidine, and reserpine. Intervention : Increased frequency of glucose monitoring may be required when LANTUS is coadministered with these drugs. Drugs that Affect Glucose Metabolism : Adjustment of insulin dosage may be needed.

( 7 ) Antiadrenergic Drugs ( e.g., beta-blockers, clonidine, guanethidine, and reserpine ): Signs and symptoms of hypoglycemia may be reduced or absent. ( 7 )

8.1 Pregnancy Risk Summary Published studies with use of insulin glargine during pregnancy have not reported a clear association with insulin glargine and adverse developmental outcomes (see Data ) . There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations ) . Rats and rabbits were exposed to insulin glargine in animal reproduction studies during organogenesis, respectively 50 times and 10 times the human subcutaneous dosage of 0.2 units/kg/day. Overall, the effects of insulin glargine did not generally differ from those observed with regular human insulin (see Data ) . In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The estimated background risk of major birth defects is 6% to 10% in women with pregestational diabetes with a peri-conceptional HbA1c >7 and has been reported to be as high as 20% to 25% in women with a peri-conceptional HbA1c >10. The estimated background risk of miscarriage for the indicated population is unknown. Clinical Considerations Disease-Associated Maternal and/or Embryo-fetal Risk Hypoglycemia and hyperglycemia occur more frequently during pregnancy in patients with pre-gestational diabetes.

Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity. Data Human Data Published data do not report a clear association with insulin glargine and major birth defects, miscarriage, or adverse maternal or fetal outcomes when insulin glargine is used during pregnancy. However, these studies cannot definitely establish the absence of any risk because of methodological limitations including small sample size and some lacking comparator groups.

Animal Data Subcutaneous reproduction and teratology studies have been performed with insulin glargine and regular human insulin in rats and Himalayan rabbits. Insulin glargine was given to female rats before mating, during mating, and throughout pregnancy at doses up to 0.36 mg/kg/day, which is approximately 50 times the recommended human subcutaneous starting dosage of 0.2 units/kg/day (0.007 mg/kg/day), on a mg/kg basis. In rabbits, doses of 0.072 mg/kg/day, which is approximately 10 times the recommended human subcutaneous starting dosage of 0.2 units/kg/day on a…
