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 in the United States, 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 glucose sensor that continuously tracks your blood sugar levels throughout the day and night. It sends real-time readings directly to your smartphone, so you always know where your glucose stands — no fingersticks required.
First FDA-cleared over-the-counter CGM in the US
Designed for adults with type 2 diabetes not using insulin
Worn on the back of the upper arm for up to 15 days
Pairs with the free Stelo app on iOS and Android
No prescription or doctor's visit needed to purchase
How Does the Dexcom Stelo Work?
The Stelo uses a tiny, flexible sensor that sits just under the skin to measure glucose levels in your interstitial fluid every few minutes. The data is sent wirelessly to the Stelo app, where you can view trends, patterns, and alerts. Setup is simple and can be done entirely at home in just a few minutes.
Who Is the Dexcom Stelo Best For?
The Stelo was designed with a specific group of people in mind — those who want glucose insights without the complexity of a prescription device. It's a great fit for people who want to take a more proactive approach to their health.
Adults with type 2 diabetes managing with diet, exercise, or non-insulin medications
People who want to understand how food and activity affect their glucose
Caregivers supporting a loved one with diabetes
Anyone who finds traditional fingerstick testing inconvenient
Health-conscious individuals wanting to monitor metabolic health

What Are the Limitations of the Dexcom Stelo?
The Stelo is a wonderful tool, but it's important to know it's not designed for everyone. Understanding its limitations helps you decide if it's the right fit for your diabetes management routine.
Not recommended for people who use insulin
Does not replace medical advice or prescribed CGM devices
May not be covered by insurance since it's an OTC product
Requires a compatible smartphone to view readings
Alerts for critically high or low glucose are limited compared to prescription CGMs
Dexcom Stelo vs. Prescription CGMs: What's the Difference?
Prescription CGMs like the Dexcom G7 are designed for people with more intensive glucose management needs, including those using insulin. The Stelo is a simplified, more affordable entry point that makes CGM technology accessible to a much wider audience. Both serve important roles depending on where you are in your diabetes journey.
