Generic Name: Insulin Glargine

  • What is this medication and its most common uses?

    Lantus is a long-acting insulin used to control high blood sugar in people with diabetes. Lantus is available as a cartridge for use in the OptiClik device, a prefilled SoloStar pen, and vials.

  • What should I know when beginning and continuing on this medication?

    How does this medication work? Your body needs insulin to turn sugar into energy. Diabetes develops when your body does not make enough insulin or does not properly use the insulin it makes. Lantus may help control your blood sugar levels by allowing blood sugar to move from your bloodstream into your cells for energy. What are the beneficial effects of this medication and when should I begin to have results? What: Lowering your blood sugar to a normal level may prevent or delay potential complications associated with diabetes, such as blindness, kidney failure, or heart problems. Lantus provides a steady release of insulin to help control blood sugar between meals and overnight for up to 24 hours. Because it works for 24 hours, Lantus is injected just once a day, which may make it easier for you to remember. When: Lantus may control your blood sugar levels over the course of a day. How do I know it is working? Check your blood sugar regularly and as your healthcare provider tells you to. Your healthcare provider will also do regular blood tests to measure your blood sugar levels and your hemoglobin A1C (measures your average blood sugar levels over a 2- to 3-month period). Stay on your prescribed diet and exercise program, as this will also affect the results of your blood tests.
