What Is Toujeo Insulin?

Toujeo is an injectable medication for the treatment of type 1 or type 2 diabetes.

Insulin glargine is long-acting insulin in Toujeo. This medication is given as a subcutaneous injection.

What Is Long-Acting Insulin?

Insulin is a hormone that is produced in the pancreas. This helps lower blood sugar levels by allowing your cells to absorb glucose and use it for energy.

Long-acting insulin is a type of insulin used to regulate the level of sugar in your blood when you have diabetes type 1 or 2 by replacing the insufficient amount of natural insulin that is produced in a person's pancreas or its ability to use the glucose effectively. Long-acting insulin is taken once or twice daily and can last for 18, 24, 36, 48 hours. The long duration allows better coverage for between-meal glucose spikes and decreases the risk of hypoglycemia.

These are other long-acting insulins:

  • Humalog
  • Novolog
  • Levemir (contains insulin detemir)

Insulin has been used to treat diabetes for over 100 years. It is currently the most commonly prescribed medication for people with type one or type two diabetes. The main goal of insulin therapy is to balance glucose levels in the blood so that it does not have dangerous effects on the body.

Insulin is administered through subcutaneous injection using prefilled disposable pens, insulin pumps, or syringes with needles.
