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.

Answers to Common Questions

You already know that adding insulin to your treatment plan is a life-changing event and there are many things to think about. Even after you've researched it, talked about it, tried different lifestyle changes, you may still have some questions. That's normal-so we've provided some answers that may help.

What is A1C?

A1C measures your average blood sugar levels over the past 2 to 3 months. It provides an accurate view of your success managing blood sugar over a longer period of time. The ADA recommends an A1C of less than 7% for most people with diabetes. Ask your doctor about blood sugar goals that are right for you, and if your A1C is too high, ask about ways you can get it on track.

How often should A1C be checked?

It should be done 2 to 4 times each year depending on how well your blood sugar levels are under control. Ask your doctor what's right for you.

Can I use Lantus® along with short- or rapid-acting insulins?

Lantus® can be used with mealtime insulins. Lantus® helps control blood sugar levels between meals and overnight. Mealtime insulins (short- or rapid-acting insulin) are taken with meals to help control blood sugar spikes caused by food. So your doctor may prescribe a mealtime insulin to work
with Lantus®.

How much can I exercise while taking Lantus®?

When you exercise, your muscles use up sugar. The harder you work out, the more your blood sugar levels fluctuate. That's why before starting any exercise program, talk to your doctor first. Generally, people with diabetes should always exercise in moderation, and make sure they have food and water with them.

Will I always be on the same dose of Lantus®?

Probably not. At first, your healthcare professional may adjust your dose of Lantus® to find what works for you. You may start with a low dose to see how well Lantus® helps control your blood sugar. Your healthcare professional may then change the amount. This change is a normal part of the process of improving your blood sugar levels. If, after you start taking Lantus®, your blood sugar level stays too high, and your healthcare professional doesn't change your dose, ask why.

What should I do if I become pregnant?

Contact your doctor immediately.

Does taking more insulin mean I am getting worse?

Type 2 diabetes can get harder to handle over time, which happens when the body isn't producing enough insulin, or not using insulin properly. The type of medicine you take, the dose you take, and the length of time using the medicines don't necessarily indicate the severity of your disease.
