What Is NovoLog®?

NovoLog® helps improve blood sugar control in people with diabetes. It is used to help lower blood sugar in adults and children with type 1 diabetes (aged 2 years and older) and adults with type 2 diabetes.

But you may hear your health care provider refer to it by a few other names:

  • As an insulin that you take at mealtime, NovoLog® is usually called “mealtime” or "bolus" insulin
  • Because it goes to work quickly, it is also sometimes called “rapid-acting” or “fast-acting” insulin
  • It is also called "analog insulin" because it is a man-made insulin that is a slightly changed version of the insulin your body makes naturally

All of these things are true.

What is NovoLog®?

NovoLog® is a fast-acting mealtime insulin that helps lower mealtime blood sugar spikes. It has been proven to help control high blood sugar in people with diabetes when taken with a long-acting insulin. And, it has been used by millions of people since 2001.

NovoLog® is fast-acting and works to help control blood sugar spikes when you eat. You should take NovoLog® and eat within 5 to 10 minutes. So you don’t have to wait 30 minutes before you eat, like you would with regular human insulin.

Controlling your blood sugar at mealtime with NovoLog® can help lower your A1C when taken with a long-acting insulin.

And, NovoLog® has a low rate of low blood sugar (also known as hypoglycemia). Keep in mind that low blood sugar is a common side effect of all insulins, including NovoLog®.

NovoLog® is a fast-acting analog insulin, but it is not the only analog insulin. Different types of analog insulin are available. Each type of insulin helps keep diabetes under control. But no one type is right for everyone. Each person's insulin needs are different. And each person's insulin needs may change over time. Here is some additional information to help you if your health care provider discusses other insulin options with you.

Types of Insulin

Type How It Works
Long-acting insulin Works to control blood sugar between meals and when you sleep. Long-acting insulin is taken either once or twice a day at the same time every day to help give up to 24-hour insulin coverage. This is often the first insulin prescribed for type 2 diabetes.
Rapid or fast-acting insulin (mealtime) This type is taken shortly before mealtime. It works quickly to control the rapid rise in blood sugar after meals. Fast-acting insulin closely mimics the body's natural release of insulin at mealtime. NovoLog® is an example of a fast-acting analog insulin.
Premix insulin Premix insulin combines the action of a rapid and long-acting insulin.
