❗ Warnings & precautions

🔄 Drug interactions

🤰 Pregnancy

Published studies of insulin glargine products in pregnancy have not reported a clear association with adverse developmental outcomes, but these studies cannot definitively rule out risk. Poorly controlled diabetes in pregnancy increases the risk of diabetic ketoacidosis, pre-eclampsia, spontaneous abortion, preterm delivery, delivery complications, major birth defects, stillbirth, and macrosomia-related morbidity. Consult your doctor before use.

🧒 Children

Safety and effectiveness are established in pediatric patients aged 6 to 15 years with type 1 diabetes. They have not been established in children younger than 6 years with type 1 diabetes or in pediatric patients with type 2 diabetes. Pediatric patients had a higher incidence of severe symptomatic hypoglycemia compared with adults in type 1 diabetes trials.

👴 Older adults

Use caution in elderly patients: initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemia, which may be difficult to recognize in the elderly. No overall differences in safety or effectiveness were observed, but greater sensitivity in some older individuals cannot be ruled out.

🌡️ Storage

Keep in the original sealed carton, protected from heat and light. Do not freeze. Unopened pens: room temperature (up to 86°F/30°C) for 28 days, or refrigerated (36°F–46°F/2°C–8°C) until the expiration date. In-use (opened) pens: room temperature (up to 30°C) for 28 days, do not refrigerate; discard after 28 days even if some insulin remains.

⏰ Missed dose

The label does not give specific instructions for a missed dose. The medicine is injected once daily at the same time each day; ask your doctor or pharmacist what to do if you miss a dose, and do not double the dose without medical advice.

🆘 Overdose

Excess insulin relative to food intake or energy expenditure may cause severe, prolonged, and life-threatening hypoglycemia and hypokalemia. Mild episodes can be treated with oral glucose. Severe episodes with coma, seizure, or neurologic impairment may be treated with emergency glucagon or concentrated intravenous glucose; sustained carbohydrate intake and observation may be needed because hypoglycemia may recur. Seek emergency care immediately.

👨‍⚕️ For healthcare professionals

Mechanism of action

Long-acting human insulin analog produced by recombinant DNA technology in E. coli (K12). It regulates glucose metabolism by stimulating peripheral glucose uptake (especially skeletal muscle and fat) and inhibiting hepatic glucose production; it also inhibits lipolysis and proteolysis and enhances protein synthesis. Pharmacodynamics: median time to maximum effect approximately 12 hours, with sustained glucose lowering over 24 hours and no pronounced peak.

Labeled dosing

Dosage is individualized and adjusted by the physician based on metabolic needs, glucose monitoring results, and glycemic goals. Administered subcutaneously once daily at the same time each day. Type 1 diabetes: starting dose approximately one-third of total daily insulin requirements, with short- or rapid-acting pre-meal insulin for the remainder. Type 2 diabetes: starting dose 0.2 units/kg or up to 10 units once daily. When changing from another insulin glargine 100 units/mL product, use the same dose; from once-daily insulin glargine 300 units/mL, the initial dose is 80% of that dose. Pens dial in 1-unit increments, maximum 80 units per injection.
