Lantus Boxed Warnings
Instruct patients on diet, exercise, blood or urine testing, proper administration of insulin, change in species of origin, type or purity of insulin, and management of hypoglycemia. Do not reuse or share pens, needles, or syringes between patients, even if the needle is changed. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis. Increased risk of hyperglycemia or hypoglycemia if changes in physical activity, meal patterns, renal or hepatic function, insulin regimen, administration site, and if acute illness occurs: monitor glucose more frequently and may need to adjust dose. Discontinue if hypersensitivity reactions occur. Monitor potassium levels in patients at risk for hypokalemia (eg, concomitant K+-lowering or K+-sensitive drugs). Renal or hepatic impairment. Elderly. Pregnancy. Nursing mothers.
Do not mix or dilute with other insulins. Increased risk of hypoglycemia with concomitant antidiabetic agents, pramlintide, ACE inhibitors, disopyramide, fibrates, fluoxetine, MAOIs, propoxyphene, salicylates, somatostatin analog, sulfonamide antibiotics, GLP-1 receptor agonists, DPP-4 inhibitors, SGLT-2 inhibitors. Reduced efficacy with concomitant atypical antipsychotics (eg, olanzapine, clozapine), steroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, protease inhibitors, somatropin, sympathomimetics (eg, albuterol, epinephrine, terbutaline), thyroid hormones; monitor more frequently. Concomitant thiazolidinediones (TZDs) may cause fluid retention and heart failure; consider dose reduction or discontinue TZDs. Variable effects with β-blockers, clonidine, lithium salts, alcohol, pentamidine. Concomitant β-blockers, clonidine, guanethidine, or reserpine may blunt hypoglycemia; monitor.
