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.

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.

Lantus®: Part of an Overall Diabetes Treatment Plan

You didn't choose diabetes. However, you and your doctor can choose the right treatment plan for you to balance diet, exercise, and diabetes medicines. By choosing to monitor your blood sugar, plan your meals, and stay physically active, you're taking a positive step toward blood sugar control.

Follow Your Meal Plan
Follow Your Meal Plan

People find it helpful to create their meals using a planning process. A simple and popular one is the Plate Method. Using this method at lunch and dinner, you would divide your plate into sections filling 1/2 with non-starchy vegetables, 1/4 with lean, low-fat protein, and 1/4 with carbohydrates (breads or grains). Then add an 8 oz. glass of milk or other small carb serving (light yogurt, for example), and a piece of fruit or salad.

Get to know which home-cooked, restaurant, and fast food meals meet your daily goals. Our GoMeals® app can help you make good food choices for your individual meal plan as suggested by your healthcare team.

Why Make Exercise a Part of Your Day?

Aside from giving you more energy, exercise makes your body more sensitive to the insulin you make (or take). Physical activity also burns glucose (calories). Both actions lower blood sugar.

Here are some ideas to help you get started:

  • 1Take the stairs instead of the elevator
  • 2When possible, ride your bicycle instead of driving
  • 3Go bowling, take a hike, or take a long walk
  • 4Find an activity you enjoy and fit it into your day

Talk to your healthcare team before you start any exercise plan.
