How Does Lantus Work Whats Its Half

Lantus is used to help control blood sugar levels in certain people who have diabetes.

Diabetes is a condition that leads to high blood sugar. With diabetes, your body cant effectively use the insulin thats made in your pancreas. Or your pancreas just doesnt make enough insulin.

Lantus is a type of insulin. Its mechanism of action is to add to or replace the insulin thats naturally made by the human body.

Lantus helps lower your blood sugar level by:

  • helping your muscle cells and fat cells take up sugar from your blood
  • keeping your liver from making more blood sugar
  • stopping your body from breaking down fats and proteins so it can break down blood sugar instead

Lantus half-life is about 12 hours. In other words, it takes about 12 hours for your body to get rid of half of a dose of Lantus.

If you have more questions about how Lantus works or its half-life, talk with your doctor or pharmacist.

What Other Drugs Will Affect Lantus

Many drugs can affect your blood sugar and may also affect Lantus. Some medicines can increase or decrease the effects of insulin. Some drugs can also cause you to have fewer symptoms of hypoglycemia, making it harder to tell when your blood sugar is low. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all other medicines you use. Not all possible interactions are listed here.

Lantus is used for the treatment of adults with type 2 diabetes, and also adults and children aged six and older with type 1 diabetes for the control of high blood sugar. It supplies a steady release of insulin to help control your blood sugar levels overnight and between meals.

Treatment with Lantus may also need the support of faster-acting mealtime insulin that helps reduce the effects of blood sugar spikes that occur during and after meals. It is usually taken in the evening or night time by people having type 1 diabetes, latent autoimmune diabetes of adults but rarely with those with type 2 diabetes. It is typically self-injected subcutaneously once daily. Lantus is not to be used to treat diabetic ketoacidosis .

What Drugs Interact With Metformin And Lantus


  • Cimetidine , by decreasing the elimination of metformin from the body, can increase the amount of metformin in the blood by 40%. This may increase the frequency of side effects from metformin.
  • Ioversol and other iodinated contrast media may reduce kidney function, which reduces elimination of metformin, leading to increased concentrations of metformin in the blood. Metformin should be stopped 48 hours before and after use of contrast media.
  • Thiazide diuretics, steroids, estrogens, and oral contraceptives may increase blood glucose and reduce the effect of metformin. When these drugs are stopped, patients should be closely observed for signs of low blood glucose.
  • Alcohol consumption increases the effect of metformin on lactate production, increasing the risk of lactic acidosis.


There are many drugs that do not directly interfere with insulin glargine, but they may affect glucose breakdown in the body. This necessitates adjustments of insulin glargine doses.

Pramlintide , disopyramide , fenofibrate , fluoxetine , and aspirin can increase blood-sugar-lowering effect of insulin glargine.

Will I Still Use My Mealtime Insulin Or Other Insulins With Lantus

You might. Lantus is a long-acting insulin thats meant work over the course of an entire day. Long-acting insulin is typically called basal or background insulin because it helps control blood sugar levels between meals and overnight while you sleep.

However, Lantus isnt typically used to control blood sugar spikes after meals. You may need a rapid-acting insulin, short-acting insulin, or intermediate-acting insulin to fine-tune your blood sugar level control. Many people who use a long-acting insulin such as Lantus will also need rapid-acting or short-acting insulin to control blood sugar levels after meals.

If you do take more than one type of insulin, dont mix Lantus in the same syringe with any other insulins. This could change how well the insulins work.

If you have any questions about when or how to take each type of insulin, talk with your doctor or pharmacist.
