Key takeaways
Tresiba (insulin degludec) and Toujeo (insulin glargine) are both long-acting insulins used to manage diabetes, but they have some key differences. Tresiba is only available as a brand-name medication, while Toujeo also comes in brand-name forms but is a more concentrated version of insulin glargine. Tresiba can be used in children as young as 1 year old, whereas Toujeo is approved for children starting at 6 years old. Tresiba works up to 42 hours once injected, while Toujeo can work up to 36 hours. Both medications are injected under the skin once daily, but Tresiba offers more flexibility as it can be taken at any time of the day. Additionally, Tresiba pens can be stored at room temperature for up to 56 days, similar to Toujeo pens. Both insulins can cause low blood sugar and weight gain, but they should not be mixed with other insulins.
