Managing diabetes is hard enough, and the high cost of continuous glucose monitors (CGMs), insulin pumps and disposable insulin pens can make transitioning from syringes feel out of reach. On May 7, 2025, Danish company GO-Pen ApS received FDA 510(k) clearance for its refillable GO-Pen insulin pen, unlocking a simpler, safer and more affordable option for insulin delivery in the U.S.

In this article, we will cover:

  • What the GO-Pen is and how it compares to other insulin delivery methods.
  • Key benefits: cost-effectiveness, a three-day reservoir, dosing precision and improved safety.
  • How it tackles financial and environmental barriers.
  • Real-world testimonials from people using GO-Pen.

Why GO-Pen is a smarter option

How to use the Go-Pen

Using the Go-Pen is simple:

  • Fill the Reservoir: Draw insulin from a standard vial.
  • Set the Dose: Adjust the dial for accurate measurement.
  • Inject: Use the pen like a traditional insulin injector.
  • Store Properly: Keep it at the recommended temperature for longevity.

How the GO-Pen helps with cost challenges in insulin delivery

  • By enabling refills from standard insulin vials, it lowers per-dose costs, making insulin more accessible.
