Dexcom Stelo Review: The First OTC CGM You Can Buy Without a Prescription
Managing blood sugar just got a whole lot easier — and more accessible. The Dexcom Stelo is the first continuous glucose monitor (CGM) approved for over-the-counter sale, meaning you can get it without a doctor's prescription. Whether you're living with type 2 diabetes or simply want to keep a closer eye on your glucose levels, this is a game-changer worth knowing about.
What Is the Dexcom Stelo?
The Dexcom Stelo is a wearable CGM sensor that tracks your glucose levels continuously throughout the day and night. It was cleared by the FDA in 2024 specifically for adults who don't use insulin, making it the first of its kind available over the counter.
No prescription required to purchase
Designed for adults with type 2 diabetes or prediabetes
Worn on the back of the upper arm for up to 15 days
Sends real-time glucose readings to your smartphone
No fingerstick calibration needed
How Does the Dexcom Stelo Work?
The Stelo uses a tiny sensor inserted just under the skin to measure glucose in your interstitial fluid every few minutes. It connects wirelessly to the free Dexcom Stelo app on your phone, where you can view trends, patterns, and alerts at a glance. Setup is simple and takes just a few minutes — no special training required.
Who Is the Dexcom Stelo Best For?
The Stelo was specifically designed with a certain group of people in mind. It's a fantastic option if you want to understand how food, exercise, and stress affect your blood sugar without the complexity of a traditional prescription CGM.
Adults with type 2 diabetes who don't use insulin
People with prediabetes looking to make lifestyle changes
Anyone curious about how daily habits impact glucose levels
Those who want a simpler, more affordable CGM option
Key Features and Benefits
The Dexcom Stelo packs a lot of helpful features into a small, discreet package. Here's a quick look at what makes it stand out from other glucose monitoring options on the market.
Wear for up to 15 days per sensor
Water-resistant design — shower and swim with confidence
Easy-to-read glucose trend graphs in the app
Meal and activity logging built into the app
Affordable compared to prescription CGM systems
Dexcom Stelo vs. Traditional CGMs
Traditional CGMs like the Dexcom G7 or Libre 3 require a prescription and are typically used by people who take insulin. The Stelo fills a gap for the millions of people managing diabetes with diet, exercise, or oral medications who still want real-time glucose insights. Think of it as a more accessible entry point into continuous glucose monitoring.

The Stelo is an exciting product, but it's important to know its limitations before purchasing. Being informed helps you choose the right tool for your specific needs.
Not intended for people who use insulin
