Lantus review: all you need to know before buying

Diabetes is a dangerous disease that is spread worldwide today. Millions of people suffer from its complications. Some even die because the right treatment is not being done. Diabetes does not spare anyone. It develops both among the poor people of developing countries, and among the rich from already fully developed and modern societies. Experts note that the age of the disease is getting younger every year. 50 years ago, it was difficult to meet a person with diabetes at the age of 20. The wrong lifestyle and an unhealthy diet are to blame. However, diabetes is not a sentence. People can live a full life for years without noticing the disease. The main criterion for such a life is compliance with the prescribed treatment. The intake of specialized antidiabetic drugs is included in it. Today we will tell you about Lantus, one of the most effective drugs that you can find on the market.

What is Lantus?

Lantus is an injectable anti-diabetic medicine. Its active substance is Insulin glargine. This is an analog of human insulin, which begins to act a few hours after administration. Its main difference from regular insulin is the uniformity of work within 24 hours after ingestion. The hormone is involved in the body’s energy metabolism and helps cells absorb glucose and generate energy. Endocrinologists use Lantus to maintain a stable blood glucose level in patients with both types of diabetes (1 and 2). In the second case, insulin injections are necessary in severe cases of the disease. Lantus is suitable for both adults and children. Thanks to a long and uniform effect on the body, Insulin glargine prevents sudden surges in sugar.

The composition of the drug

Lantus consists of several components. Insulin glargine is the main active ingredient. In addition to it, the medicine contains the following excipients: m-cresol, glycerol, zinc, polysorbate, and water. Together, they form a solution that helps the active substance quickly enter the patient’s blood.

Dosage form

Lantus is a clear solution that is administered to patients by subcutaneous injection. 1 ml of the drug contains 100 units of insulin. There are 2 types of distribution:

  • Bottle of 10 ml with several doses
  • 3 ml prefilled pens for single-use

Both forms of distribution of the drug are in cardboard packaging.

How to take Lantus?

The patient should take the prescribed Lantus by injection in the abdomen or thigh. Insulin glargine acts uniformly for 24 hours, so the injection should be done 1 time per day at the same time. Eating does not affect the effectiveness of the drug. The daily dosage for each type of diabetes is calculated individually.

Insulin-dependent diabetes (type 1). The patient should use Lantus with short-acting insulin. Endocrinologists recommend using Insulin glargine with a minimum dosage of 1/3 of the required daily volume of the hormone, and 2/3 should be on short-acting insulin. In the future, this ratio may be adjusted in favor of Lantus. The decision to change the proportions should be made by the attending physician. It is forbidden to make such a decision on your own.

Non-insulin-dependent diabetes (type 2). The minimum initial daily dosage of Lantus is calculated from a ratio of 0.2 units/kg. Moreover, the maximum dosage at the beginning of therapy should not exceed 10 units per day.

Endocrinologists prescribe Insulin glargine to patients who have not taken insulin before and their blood glucose level is not reduced. After a few weeks, the dosage of Lantus can be adjusted by taking oral antidiabetic agents.


Clinical studies have shown that Lantus is suitable for treating almost any patient. The drug has only a few contraindications: individual hypersensitivity to the components of the drug, hypoglycemia attacks. That’s all.

Before taking Insulin glargine, the patient should tell their doctor about all concomitant diseases and their treatment (problems with the liver, kidneys, or heart). The endocrinologist uses this information to prescribe the safest and effective daily dosage.

What are the side effects?

Long-term use of Insulin glargine has shown that the drug can cause various side effects. They are not life-threatening to patients, but still unpleasant. Specialists rarely report the appearance of such symptoms in no more than 5% of all patients. Specialists most often register the following symptoms:

  • Weakness
  • Increased appetite
  • Drowsiness
  • Nausea
  • Dizziness
  • Change in skin color
  • Cold sweats
  • Anxiety
  • Nightmares
  • Slurred speech

If such symptoms appear, you should contact your doctor. The specialist will reduce the daily dose of medicine or choose the most suitable drug for you. Side effects occur due to an overdose of the drug, in rare cases due to personal intolerance to the components of the drug.

Drug interaction

Lantus interacts with other medicines, especially anti-diabetic ones. The combination of such drugs can lead to a sharp decrease in blood glucose and the development of hypoglycemia. This is a life-threatening condition, so it is very important to inform your doctor about all the medications you take. In addition, the prescribed dosages should be strictly adhered to. With careful attention to your treatment, very soon the blood glucose level will stabilize and you will be able to fully enjoy life.

Storage conditions

You should store Lantus in a cool place at a temperature of 2-8 degrees Celsius. With an increase in this temperature, the shelf life is only 28 days. Lantus should be kept in a dark and safe place. Subject to all storage rules, the shelf life of the drug will be 3 years from the date of release.
