Caring for Your LANTUS® SoloSTAR® Insulin Pen

Following these few straightforward steps can help maintain the quality of your LANTUS® SoloSTAR® pen.

To help ensure an accurate dose each time, follow all steps in the Instruction Leaflet that comes with your pen. Otherwise, you may not get the correct amount of insulin, which may affect your blood sugar levels.

Before you use the LANTUS® SoloSTAR® pen:

  • Keep your unopened pen(s) in the refrigerator, in their outer package
  • Don't put them next to the freezer or near a freezer pack—frost will damage the insulin
  • Before you inject with a pen, remove it from the refrigerator for an hour or two—cold insulin can be more painful to inject

After you open the LANTUS® SoloSTAR® pen:

  • Don't refrigerate it
  • Use it for up to 28 days
  • Store it safely at room temperature (below 86°F)
  • Don't leave it anywhere it might overheat such as a car parked in sunlight, on a windowsill, or near a radiator
  • Keep the pen away from direct light or heat
  • After 28 days, throw it away—even if it still has insulin in it
  • Occasionally clean pen with a damp cloth. Do not run it under water, use soap, or cleaning solutions

Other important information:

  • Don't use it after the expiration date printed on the label or carton
  • Always keep at least one spare LANTUS® SoloSTAR® pen in case your current one is lost or damaged
  • Do not mix LANTUS® with any other insulin
  • Do not share needles or insulin pens with others

Important Safety Information for Lantus®

Do not take Lantus® if you are allergic to insulin or any of the inactive ingredients in Lantus®.

You must test your blood sugar levels while using insulin, such as Lantus®. Do not make any changes to your dose or type of insulin without talking to your healthcare provider. Any change of insulin should be made cautiously and only under medical supervision.

Do NOT dilute or mix Lantus® with any other insulin or solution. It will not work as intended and you may lose blood sugar control, which could be serious. Lantus® must only be used if the solution is clear and colorless with no particles visible. Do not share needles, insulin pens or syringes with others.

The most common side effect of insulin, including Lantus®, is low blood sugar (hypoglycemia), which may be serious. Some people may experience symptoms such as shaking, sweating, fast heartbeat, and blurred vision. Severe hypoglycemia may be serious and life threatening. It may cause harm to your heart or brain. Other possible side effects may include injection site reactions, including changes in fat tissue at the injection site, and allergic reactions, including itching and rash. In rare cases, some allergic reactions may be life threatening.

Tell your doctor about other medicines and supplements you are taking because they can change the way insulin works. Before starting Lantus®, tell your doctor about all your medical conditions including if you have liver or kidney problems, are pregnant or planning to become pregnant, or are breast-feeding or planning to breast-feed.

Lantus® SoloSTAR® is a disposable prefilled insulin pen. Please talk to your healthcare provider about proper injection technique and follow instructions in the Instruction Leaflet that accompanies the pen.
