Important Safety Information for Lantus® (insulin glargine [rDNA origin] injection)

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

Do not share needles, insulin pens or syringes with others. Do NOT reuse needles.

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.

Tell your doctor about other medicines, especially ones commonly called TZDs (thiazolidinediones), 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 heart failure or other heart problems, liver or kidney problems, are pregnant or planning to become pregnant, or are breast-feeding or planning to breast-feed. If you have heart failure, it may get worse while you take TZDs with Lantus®.

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 swelling, weight gain, injection site reactions, including changes in fat tissue at the injection site, and allergic reactions, including itching and rash.

Understanding Your Blood Sugar Log

You've tracked your numbers. So what do they mean?

Checking your blood sugar levels—and keeping detailed records—helps you and your doctor track your progress over time. Also, include notes to explain any unusually high or low blood sugar levels, such as what you ate, if you exercised or if you experienced any unusual symptoms. For more reasons why your numbers may rise or fall, click here. This will help your doctor better understand how your treatment is going and help you make adjustments if needed.

Any result you get is good information and can help you and your doctor react to changes appropriately and quickly.

Review Your Log and Look for Patterns

Review Your Log and
Look for Patterns

Review your blood sugar log often to see how diet, exercise, and stress are affecting your blood sugar readings. If you start to find a pattern where your levels are too high or too low, you should let your doctor know.

What the Patterns May Mean

If your readings are higher than what your doctor recommends, you may need to:

  • 1Reduce the amount of food you are eating
  • 2Increase your physical activity
  • 3Ask your doctor about adjusting your treatment plan

How Your Log Helps You and Your Doctor

Keeping a detailed log will help you and your doctor understand:

  • The effectiveness of your medicines, diet, and exercise
  • How high levels of stress affect your blood sugar levels
  • What special medicines, such as steroids for asthma or cold medicines, do to your levels

In other words, you will be more prepared to determine what's working and what isn't.
