About Blood Sugar Management

You’ve been taking Lantus® for a while. By now, you know that many things can impact your blood sugar levels. Like the foods you eat, your overall activity level, and even your stress levels.

That’s why it’s important to stay focused on your goals―for yourself and for those you love.

What target ranges are right for you?

According to the American Diabetes Association (ADA), most people with type 2 diabetes should have blood sugar levels within this range:

Before meals or upon waking:

80-130 mg/dL

2 hours after the start of a meal:

Less than
180 mg/dL

What Is A1C?

A1C test measures your average blood sugar levels over the past 2 to 3 months. It provides a picture of your success managing blood sugar over a longer period of time. Ask your doctor about blood sugar and A1C goals that are right for you, and if your A1C is too high, ask about ways you can get it on track.


It is recommended that your doctor measure your A1C level at least twice a year—minimum. There are times when you need to have your A1C level checked about every 3 months.

Proven Full 24-Hour Blood Sugar Control – Toujeo® (insulin glargine injection) 300 Units/mL

Click here for Full Prescribing Information
for Toujeo®

Prescription Toujeo® is a long-acting insulin used to control blood sugar in adults with diabetes mellitus.

  • Toujeo® contains 3 times as much insulin in 1 mL as standard insulin (100 Units/mL)
  • Toujeo® is not for use to treat diabetic ketoacidosis
  • Toujeo® should not be used in children

Do not take Toujeo® if you have low blood sugar or if you are allergic to insulin or any of the ingredients in Toujeo®.

Do NOT reuse needles or share insulin pens even if the needle has been changed.

Before starting Toujeo®, tell your doctor about all your medical conditions, including if you have liver or kidney problems, if you are pregnant or planning to become pregnant or if you are breastfeeding or planning to breastfeed.

Heart failure can occur if you are taking insulin together with certain medicines called TZDs (thiazolidinediones), even if you have never had heart failure or other heart problems. If you have heart failure, it may get worse while you take TZDs with Toujeo®. Your treatment with TZDs and Toujeo® may need to be changed or stopped by your doctor if you have new or worsening heart failure. Tell your doctor if you have any new or worsening symptoms of heart failure, including:

  • Shortness of breath
  • Sudden weight gain
  • Swelling of your ankles or feet

Tell your doctor about all medications you take, including OTC medicines, vitamins, and supplements, including herbal supplements.

Toujeo® should be taken at the same time once a day. Test your blood sugar levels daily while using insulin, including Toujeo®. Do not make changes to your dose or type of insulin without talking to your doctor. Verify you have the correct insulin before each injection. Your dose for Toujeo® may be different from other insulins you have taken. Any change of insulin should be made cautiously and only under medical supervision.

Do NOT dilute or mix Toujeo® with any other insulin or solution. It will not work as intended and you may lose blood sugar control, which could be serious. Use Toujeo® only if the solution is clear and colorless with no particles visible.

While using Toujeo®, do not drive or operate heavy machinery until you know how Toujeo® affects you. Don’t drink alcohol or use other medicines that contain alcohol.

The most common side effect of any insulin, including Toujeo®, is low blood sugar (hypoglycemia), which may be serious and can be life-threatening. Severe hypoglycemia may cause harm to your heart or brain. Symptoms of serious low blood sugar may include shaking, sweating, fast heartbeat, and blurred vision.

Toujeo® may cause serious side effects that can lead to death, such as severe allergic reactions. Get medical help right away if you have:

  • A rash over your whole body
  • Shortness of breath
  • Swelling of your face, tongue, or throat
  • Extreme drowsiness, dizziness, or confusion
  • Trouble breathing
  • Fast heartbeat
  • Sweating

Toujeo® may have additional side effects including swelling, weight gain, low potassium, and injection site reactions which may include change in fat tissue, skin thickening, redness, swelling, and itching.

Toujeo® SoloStar® is a disposable prefilled insulin pen. Talk to your doctor about proper injection technique and follow instructions in the Instruction Leaflet that comes with the pen.
