Key takeaways
Levemir (insulin detemir) and Basaglar (insulin glargine) are both long-acting insulins used to control blood sugar levels in people with diabetes. Levemir can be injected once or twice daily, while Basaglar is typically injected once daily. Levemir is available in both vials and pens, whereas Basaglar only comes in pen form. Levemir has a lower risk of weight gain compared to Basaglar, which is known to cause weight gain. Additionally, Levemir can be stored at room temperature for up to 42 days once opened, while Basaglar can only be stored at room temperature for up to 28 days. Both medications can cause low blood sugar and should not be mixed with other insulins within the same syringes. Levemir Flexpens has been discontinued as of April 2024, and vials will be discontinued by December 2024 while Basaglar is only available as a brand name, making it potentially more expensive.
