About Lantus

What Lantus is used for

LANTUS [insulin glargine injection (rDNA origin)] is a recombinant human insulin analogue that is a long-acting blood-glucose-lowering agent administered subcutaneously (under the skin) once a day. LANTUS is indicated in the treatment of patients over 17 years of age with Type 1 or Type 2 diabetes mellitus who require basal (long-acting) insulin for the control of hyperglycemia. LANTUS is also indicated in the treatment of pediatric patients with Type 1 diabetes mellitus who require basal (long-acting) insulin for the control of hyperglycemia.

What Lantus does

Insulin is a hormone produced by the pancreas, a large gland that lies near the stomach. This hormone is necessary for the body's correct use of food, especially sugar. Diabetes occurs when the pancreas does not make enough insulin to meet your body's needs or when your body cannot use properly the insulin you normally produce.

When your body does not make enough insulin, you need an external source of insulin. That is why you must take insulin injections. LANTUS is similar to the insulin made by your body.

You have been instructed to test your blood and/or your urine regularly for glucose; it is especially important to test even more often when changing insulins or dosing schedule. If your blood tests consistently show above- or below- normal glucose levels, or your urine tests consistently show the presence of glucose, your diabetes is not properly controlled and you must let your healthcare professional know.

Insulin injections play an important role in keeping your diabetes under control. But the way you live—your diet, careful monitoring of your glucose levels, exercise, or planned physical activity and following your healthcare professional’s recommendations—all work with your insulin to help you control your diabetes.

Always keep an extra supply of insulin as well as a spare syringe and needle on hand. Always wear medical alert identification and carry information about your diabetes so that appropriate treatment can be given if complications occur away from home.

Interactions with Lantus

It is not advisable to use any medical treatment, without telling your healthcare professional as there may be interactions between LANTUS and other medicines.

Tell your healthcare professional if you are taking any other medicine which has been prescribed for you or which you bought without a prescription.

Instructions for Use

Your doctor has recommended the type of insulin that he/she believes is best for you. DO NOT USE ANY OTHER INSULIN EXCEPT ON THE ADVICE AND DIRECTION OF YOUR DOCTOR.

LANTUS is a clear solution and looks like some short-acting insulins. Always check the carton and the vial label for the name of the insulin you receive from your pharmacy to make sure it is the same as the one your doctor has recommended.

Correct Syringe

It is important to use a syringe that is marked for U-100 insulin preparations since LANTUS contains 100 units/mL. Using an incorrect syringe could lead to a mistake in dosing and cause medical problems for you, such as a blood glucose level that is too low or too high.

Syringe Use


Disposable syringes and needles should be used only once and then properly discarded.


Preparing the Dose

  1. Check the vial label of the insulin.

  2. Inspect the insulin. LANTUS should be a clear and colorless solution with no visible particles. Do not use it if you notice anything unusual in the appearance of the solution.

  3. Make sure the insulin is at room temperature to minimize local irritation at the injection site.

  4. Wash your hands.

  5. It is not necessary to shake or rotate the vial before use.

  6. If using a new vial, remove the protective cap, but DO NOT remove the stopper.

  7. Wipe the top of the vial with an alcohol swab.

  8. A new sterile syringe must be used.

  9. Draw air into the syringe equal to your insulin dose. Put the needle through the rubber top of the insulin vial and inject the air into the vial.

  10. Turn the vial and syringe upside down. Hold the vial and syringe firmly in one hand.

  11. Make sure the tip of the needle is in the insulin and withdraw the correct dose of insulin into the syringe.

  12. Before removing the needle from the vial, check your syringe for air bubbles. If bubbles are present, hold the syringe straight up and tap its side until the bubbles float to the top. Push them out with the plunger and withdraw the correct dose.

  13. Remove the needle from the vial. Do not let the needle touch anything prior to injection.

  14. An empty vial must never be reused and must be properly discarded.


Cleanse the skin with alcohol where the injection is to be made. Pinch and hold the skin and insert the needle as instructed by your healthcare professional. Slowly push the plunger of the syringe in completely. Slowly count to 10 before removing the needle from the injection site and gently apply pressure for several seconds. DO NOT RUB THE AREA.

There is no relevant difference in absorption of LANTUS between abdominal, thigh, or upper arm subcutaneous injection areas. However, injection sites within an injection area (abdomen, thigh, or upper arm) must be rotated from one injection to the next.

Hypo- or hyperglycemia can result from injecting insulin in the wrong site or incorrectly. Hypoglycemia can result from injection directly into a blood vessel and if not recognized or treated may be followed by hyperglycemia since there was no LANTUS deposition for long-term absorption.

Proper Use of Lantus

Usual dose

The dosage of LANTUS should be individualized and determined based on your healthcare professional’s advice in accordance with your needs. You may take LANTUS at any time during the day, but you must take it at the same time every day.

Many factors may affect your usual LANTUS dose, which may include changes in your diet, activity, or work schedule. Follow your healthcare professional’s instructions carefully. Consult your healthcare professional if you notice your insulin requirements changing markedly. Other factors that may affect your dose of insulin or your need to do additional blood/urine testing are:


Illness, especially with nausea and vomiting, diarrhea and/or fever, may change how much insulin you need. Even if you are not eating, you will still require insulin. You and your healthcare professional should establish a sick day plan for you to use in case of illness. When you are sick, test your blood/urine frequently and call your healthcare professional as instructed.


If you are planning to have a baby, are pregnant, or are nursing a baby, consult your healthcare professional. Good control of diabetes is especially important for you and your unborn baby. Pregnancy may make managing your diabetes more difficult.


Always discuss any medications you are taking, prescription or “over-the-counter”, with your health care provider. To prevent drug interactions, volunteer the names of everything you are taking even before they ask if there have been any changes. Insulin requirements may be increased in the presence of drugs with hyperglycemic activity, such as oral contraceptives (for example, birth control pills, injections and patches), and hormone replacement therapies, corticosteroids, thyroid replacement therapy, and sympathomimetic agents such as decongestants and diet pills. Insulin requirements may be reduced in the presence of drugs with hypoglycemic activity, such as oral antidiabetic agents, salicylates (for example, aspirin), sulfa antibiotics, blood pressure medications including ACE inhibitors, and certain psychiatric medications including MAO inhibitors or antidepressants and anti-anxiety medications.

Substances including beta-blockers, used for conditions including blood pressure, heart arrhythmias, palpitations and headache, and alcohol may enhance or weaken the blood-glucose-lowering effect of insulins, and signs of hypoglycemia may be reduced or absent.
