What is Lantus?

Lantus (insulin glargine) is a man-made form of a hormone that is produced in the body. It works by lowering levels of glucose (sugar) in the blood. Lantus is a long-acting form of insulin that is slightly different from other forms of insulin that are not man-made.

Lantus is used to treat type 1 or type 2 diabetes.

Important information

Lantus is only part of a complete program of treatment that may also include diet, exercise, weight control, foot care, eye care, dental care, and testing your blood sugar. Follow your diet, medication, and exercise routines very closely. Changing any of these factors can affect your blood sugar levels.

How should I use Lantus?

Lantus is injected under the skin. You may be shown how to use injections at home. Do not self-inject Lantus if you do not understand how to give the injection and properly dispose of used needles and syringes. Do not mix this medication with other insulins.

Follow all directions on your prescription label. Do not use Lantus in larger or smaller amounts or for longer than recommended.

Use a different place in your injection skin area each time you give the injection. Your care provider will show you the best places on your body to inject the medicine. Do not inject into the same place two times in a row.

The Lantus SoloStar injection pen contains a total of 300 units of insulin. The pen is designed to deliver from 1 to 80 units with each press of the injection button. Do not press the button more than one time per injection unless your doctor has prescribed a dose greater than 80 units.

Use a disposable needle only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Never share a Lantus injection pen or cartridge with another person. Sharing injection pens or cartridges can allow disease such as hepatitis or HIV to pass from one person to another.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.

If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.

Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice.

Lantus is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.

Wear a medical alert tag or carry an ID card stating that you use insulin. Any medical care provider who treats you should know that you are diabetic.

Storing unopened vials or Lantus SoloStar devices: Keep in the carton and store in a refrigerator, protected from light. Throw away any insulin not used before the expiration date on the medicine label. Store the injection pen with its cap on.

Unopened vials or SoloStar devices may also be stored at room temperature for up to 28 days, away from heat and bright light. Throw away any insulin not used within 28 days.

Storing after your first use: You may keep "in-use" vials or cartridges in the refrigerator or at room temperature, protected from light. Use within 28 days.

Do not refrigerate an in-use Lantus SoloStar device. Keep it at room temperature and use within 28 days.

Do not freeze Lantus, and throw away the medication if it has become frozen.

What happens if I miss a dose?

Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose. You should not use more than one dose in a 24-hour period unless your doctor tells you to.

Keep Lantus on hand at all times. Get your prescription refilled before you run out of medicine completely.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An insulin overdose can cause life-threatening hypoglycemia.

What should I avoid while using Lantus?

Do not change the brand of insulin glargine or syringe you are using without first talking to your doctor or pharmacist.

Avoid drinking alcohol. It lowers blood sugar and may interfere with your diabetes treatment.

Lantus side effects

Get emergency medical help if you have any of these signs of insulin allergy: itching skin rash over the entire body, wheezing, trouble breathing, fast heart rate, sweating, or feeling like you might pass out.

Call your doctor at once if you have:

  • shortness of breath (even with mild exertion), swelling, rapid weight gain; or

  • itching, swelling, redness, or thickening of the skin where you inject insulin glargine.

Common Lantus side effects may include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
