The history of insulin

The discovery of insulin in 1921 was a major breakthrough in the treatment of diabetes. Today, millions of people around the world are using insulin. Many people have been treating their diabetes with insulin for decades.

Moving to insulin

You may already be doing things that are helpful for controlling your blood sugar, like eating nutritious meals and staying active.

But, like many people with type 2 diabetes, you may also need to take insulin at some point to keep your blood sugar level in your target range. Remember, diabetes can change over time and so can your treatment needs.

Levemir® long-acting insulin

You may have heard that common side effects of insulin can include low blood sugar (or hypoglycemia) and weight gain.

Insulin helps lower blood sugar levels by moving sugar out of the bloodstream and into the cells where the sugar can be used for energy. If too much sugar moves out of the blood, low blood sugar can occur.

In studies, people who were treated with Levemir® had a low rate of low blood sugar events. In addition, studies have shown that people with type 2 diabetes taking Levemir® can reach their A1C and daily blood sugar goals with less weight gain than Lantus®, a different long-acting insulin.
