Prescription Lantus® (insulin glargine [rDNA origin] injection) is a long-acting insulin used to treat adults with type 2 diabetes and adults and pediatric patients (children 6 years and older) with type 1 diabetes for the control of high blood sugar. It should be taken once a day at the same time each day to lower blood glucose.

Do not use Lantus® to treat diabetic ketoacidosis.

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®.

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.

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. In rare cases, some allergic reactions may be life threatening.

Month 2: Doctor Visit Checklist

Controlling blood sugar is all about managing your diet, exercise, other diabetes medicines, and Lantus® insulin. But to do that, you and your doctor need to evaluate how you are doing. That's why your doctor visits are so important.

You've worked with your doctor to set your blood sugar goals, and you're taking Lantus® to help achieve them, but do you still have questions about your treatment?

Here are some questions you may want to ask your doctor about Lantus®:

What is my A1C level?

  • A1C measures your average blood sugar level for the past 2 to 3 months.

  • The American Diabetes Association (ADA) recommends an A1C of <7% for most people with type 2 diabetes. Ask your doctor what the right A1C goal is right for you.

Now that I have started with the Lantus® SoloSTAR® pen, has my A1C level improved?

  • A1C indicates your average blood sugar level for the past 2 to 3 months, so it may be too soon to tell if your levels have improved. Your daily blood sugar readings may give you a better idea how your blood sugar levels are changing.

Does my current dose need to be changed?

  • Adjustments are common. It doesn't mean you've done anything wrong.

  • Since everyone's diabetes treatment plan, which may include diet, exercise, and other diabetes medicine, is different, it may take some time to find the right Lantus® dose for you.

I understand many healthcare professionals design a dose adjustment schedule for their patients; can you do this for me?

  • Your doctor will design a schedule that is right for you. A complete log of your blood sugar readings will help him or her determine if a dose change is needed.

Once my blood sugar is under control, will my Lantus® dose ever need to be adjusted again?

  • Any change in your lifestyle, medicines, and health conditions that you experience can change your blood sugar levels. For example, if you start a new exercise program, your blood sugar levels may change. Discuss any changes with your doctor. He or she will determine if an adjustment to your medication regimen is necessary.

Should we review my current diet, medication, and exercise program?

  • You should review your diet, medication, and exercise program at every visit, especially if you notice a change in your blood sugar levels, or if you want to change your diet or exercise plan.

  • Any change may require a change to your insulin dose. Talk to your doctor before making any change to your insulin regimen and about the need for more frequent blood sugar monitoring.

What are my goals for my next appointment?

  • When you talk to your doctor, you should take the time to set up expectations for your next visit.
