Product Details

What Is the Levemir Penfill Cartridge Used For?

What Is the Levemir Penfill Cartridge Used For?

Levemir PenFill Cartridge is a long-acting insulin used to help control high blood sugar in people with Type 1 and Type 2 diabetes. It contains insulin detemir, a synthetic form of a hormone your body needs to regulate blood glucose (sugar). The PenFill cartridge formulation provides a consistent, slow-release of insulin that helps maintain stable blood sugar throughout the day.

Levemir PenFill Cartridge does not treat sudden high blood sugar and is not used for diabetic ketoacidosis (DKA). Because diabetes management is individualized, careful monitoring and consistent use are important. Licensed Canadian pharmacies can dispense these cartridges with a valid prescription.

How Do You Use the Levemir Penfill Cartridge?

  • Check the label to ensure it’s the right insulin.

  • Always use a new needle; never share pens or needles.

Levemir 100 u/mL Penfill Cartridge Mechanism of Action

Levemir 100 u/mL Penfill Cartridge Mechanism of Action

Levemir PenFill contains insulin detemir, a long-acting insulin that works by mimicking the body’s natural basal insulin. Once injected, insulin detemir binds to blood proteins, allowing it to be released slowly and evenly. This steady release helps lower blood glucose by improving cellular glucose uptake and reducing liver glucose production.
