**Levemir vs Tresiba: A Thorough Comparison**
When managing [Type 1 and Type 2 diabetes](https://bridgecanhealth.com/type-1-vs-type-2-diabetes/), Levemir and Tresiba are two popular insulin brands that come to mind. But how do you decide between them? Read on to discover the distinctions between these two insulin options.
## **Introduction to Tresiba**
[Tresiba](https://bridgecanhealth.com/shop/insulin-tresiba-flextouch-200u-ml-3ml/) (insulin degludec) is a long-acting insulin that becomes active several hours after injection and stays effective for up to 24 hours. Its prolonged effect means that multiple daily doses aren’t required.
Available in both vials and the prefilled FlexTouch pen, [Tresiba](https://bridgecanhealth.com/shop/insulin-tresiba-flextouch-100u-ml-3ml/) can be prescribed for adults and children with Type 1 and Type 2 diabetes, though it’s not recommended for children under one year old.
The FlexTouch pen comes in two concentrations: U-100 with 300 units of insulin and U-200 with 600 units.
## **Introduction to Levemir**
Levemir, another long-acting insulin, contains insulin detemir. It starts working a few hours after injection, with effects lasting up to 24 hours, making it comparable to Tresiba.
