Ultra long-acting insulin is a treatment option for people with type 2 diabetes (T2D). It is used to control blood sugar. Ultra long-acting insulin starts to work a few hours after injection and stays active for up to 42 hours.1-3
Insulin is what helps the body store and use energy from glucose. People with T2D make insulin in their bodies, but they do not respond well to it. This is why they may need to take insulin as a treatment.1
An ultra long-acting insulin may be recommended when:3,4
- Effects of other insulin treatments do not last a full day
- Improved absorption is desired
- Flexible dosing is desired
How does ultra long-acting insulin work?
Ultra long-acting insulin is different from other insulin types that work on rapid, short, intermediate, or long time frames. While it takes up to 6 to 12 hours to reach the maximum effect, it is released slowly and steadily over time. It does not peak and mimics the rate at which the pancreas would normally release insulin. This helps to keep your blood sugar levels controlled and steady over long periods of time.1,2,4
Ultra long-acting insulin is usually taken once a day. It must be injected into the fat layer under the skin to reach the bloodstream.2,3
Ultra long-acting insulin treatments are available in different doses. Your doctor will decide which is most helpful for you. Your doctor may also prescribe other T2D drugs in addition to an ultra long-acting insulin.2,4
