When and How to Take Lantus

General considerations for when and how to take Lantus include the following:
  • This diabetes medication comes in an injectable form. It is injected just under the skin (subcutaneously) once a day.
  • Your healthcare provider should show you exactly how to inject it. It can be injected into the skin and fat layer of the abdomen (stomach), upper arm, or thigh. Choose one of these three areas, and rotate injection sites within your chosen area, but do not rotate between different areas, as Lantus may be absorbed differently from various areas.
  • Lantus comes in vials and the disposable SoloSTAR® pen device. To use the pens, you will need specific types of needles known as "pen needles." Each time you inject Lantus, you will need to use a new needle. To use Lantus from the vial, you will need insulin syringes with needles.
  • Because Lantus is a solution, not a suspension, you don't need to shake or swirl it.
  • Never mix Lantus with any other insulin in the same syringe. Never dilute it.
  • For Lantus to work properly, it must be taken as prescribed. It will not work if you stop taking it. Make sure to monitor your blood sugar levels as your healthcare provider recommends.

Dosing Information

The Lantus dosage your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your current dose of other insulins
  • How you respond to Lantus (especially as measured by your blood sugar levels)
  • Other medications you are taking
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
