Diabetes is one of the most widespread health issues that so many people have to experience. However, insulin therapy isn't the same as it used to be just several decades ago, as the introduction of insulin pens made insulin administration so much easier.

Still, despite their convenience of insulin pen use, it's still worth investing extra time to learn more about these devices.

What Are Insulin Pens?

A pen-shaped device is used by patients with diabetes for daily hormone injections. It has a needle and pre-filled cartridges inside, and the dose of insulin glargine can be adjusted with a dial on the device's body.

Types of Insulin Pen Devices

Currently, there are 2 main types of injection pens:

  • Disposable insulin pen - after a patient runs out of cartridges, he or she throws the device away and uses a new one;
  • Reusableinsulin pen - it's possible to re-load the device with prefilled cartridges, and there's no need to throw it away.

In both cases, after the insulin injection is delivered, a needle must be replaced.
