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.
What is the GO-Pen insulin pen?
- GO-Pen’s FDA approval allows it to enter the U.S. market and expand internationally.
- It has won multiple diabetes innovation awards.
- Created by Ole Kjerkegaard Nielsen and Michael Hansen, it leverages Novo Nordisk expertise with a multi-day insulin supply for precise dosing and less waste.
Why GO-Pen is a smarter option
- Reduces dosing errors: Insulin pens like the GO-Pen help minimize medication errors compared to syringes.
- Reduces daily injections: It carries a multi-day insulin supply, making it easier than using syringes daily.
- Improves safety: Studies show that pen delivery reduces the risk of needlestick injuries compared to traditional syringes.
- Travel-friendly: It is compact and portable, ideal for busy lifestyles or travel.
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
- Despite diabetes technology advancements, over 20 million insulin users worldwide (3 million in the U.S.) still rely on vials and syringes due to cost and access barriers.
- While CGMs, insulin pumps and prefilled insulin pens offer convenience, they often come with higher price tags.
- By enabling refills from standard insulin vials, it lowers per-dose costs, making insulin more accessible.
Making insulin more affordable and sustainable
- GO-Pen helps people with diabetes save money and reduce waste.
- It improves access to affordable insulin, especially in low-resource areas where disposable supplies are costly or scarce.
