Learn about rapid-acting insulin options from Novo Nordisk

Novo Nordisk rapid-acting insulins are used to help people with type 1 or type 2 diabetes control their high blood sugar.

What is rapid-acting insulin?

Also known as fast-acting insulin, mealtime insulin or bolus insulin, rapid-acting insulins may be a part of your treatment plan if you have type 1 or type 2 diabetes.

Rapid-acting insulins help control your blood sugar when taken as prescribed, which is usually before or after a meal. This type of insulin may be injected with an insulin pen, through a pump, or with a vial and syringe.  

How does rapid-acting insulin work?

When you inject insulin into your body, your blood sugar level goes down.

  • Insulin works like a key, unlocking the doors of the cells in your body
  • Once the cell doors open, sugar is able to move from the blood into the cells, where it belongs
  • Once inside the cells, sugar provides energy to the body

Rapid-acting insulins are designed to be absorbed by the body at a faster rate to lower blood sugar after meals.
