Lantus (insulin glargine) (insulin glargine) — Uses, Dosage, Side Effects & Safety

Drug class: Long-acting insulin (antidiabetic agent)

Overview

Lantus (insulin glargine) is a long-acting insulin used to help control blood sugar in people with diabetes mellitus, including both type 1 and type 2 diabetes. It provides a steady, consistent level of insulin over 24 hours, helping to reduce high blood sugar and prevent complications from diabetes. Insulin glargine works by replacing the insulin that your body either does not produce or does not use effectively. It helps glucose (sugar) enter your cells so your body can use it for energy. Lantus is typically injected once daily, at the same time each day, to maintain stable blood sugar levels. Key points for patients: Always use Lantus exactly as prescribed, monitor your blood sugar regularly, and be aware of signs of low blood sugar (hypoglycemia). Never share your insulin pen or syringe with others.
