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 over-the-counter continuous glucose monitor (CGM) approved by the FDA, meaning you can now track your glucose levels in real time without ever needing a doctor's prescription. Whether you're living with type 2 diabetes or simply want to keep a closer eye on your metabolic health, the Stelo could be a true game-changer.

What Is the Dexcom Stelo?

The Dexcom Stelo is a wearable CGM sensor that sits on the back of your upper arm and automatically tracks your glucose levels every few minutes — no finger pricks required. It sends your readings directly to your smartphone, giving you a continuous picture of how food, activity, and daily habits affect your blood sugar.

• First FDA-cleared over-the-counter CGM for adults

• No prescription needed — available to anyone 18 and older

• Worn on the back of the upper arm for up to 15 days

• Syncs wirelessly to the free Dexcom Stelo app on your smartphone

• Works without a receiver — your phone does all the work

Who Is the Dexcom Stelo Designed For?

The Stelo was specifically designed for adults who are not on insulin, making it a great fit for people managing type 2 diabetes with diet, exercise, or oral medications. It's also popular with people who are prediabetic or simply curious about how their lifestyle choices impact their glucose levels.

• Adults with type 2 diabetes not using insulin

• People with prediabetes wanting to monitor trends

• Health-conscious individuals tracking metabolic wellness

• Those looking for a prescription-free CGM option

Key Features of the Dexcom Stelo

The Stelo packs impressive technology into a small, discreet sensor that you barely notice once it's on. Dexcom has made the experience beginner-friendly, so even if you've never used a CGM before, you'll be up and running in just a few minutes.

• Continuous readings every few minutes, day and night

• Up to 15 days of wear per sensor

• Water-resistant design — safe for showers and swimming

• Easy-to-read graphs and trend arrows in the app

• Gentle alerts when glucose levels go too high or too low

What We Love About the Stelo

One of the biggest wins with the Dexcom Stelo is how it removes barriers to CGM technology that many people have faced for years. No doctor visit, no prior authorization, no insurance hassle — just real-time glucose data at your fingertips.

• Truly over-the-counter — no prescription required

• Affordable compared to traditional CGM systems

• Simple setup process even for first-time users

• Helps users see patterns and make smarter daily choices

Any Limitations to Keep in Mind?

The Stelo is a wonderful tool, but it's important to know it's not designed for people who use insulin or those prone to severe hypoglycemia — those individuals should speak with their doctor about prescription CGM options like the Dexcom G7. The Stelo also does not have customizable low-glucose alarms like some clinical-grade CGMs.

How Does the Dexcom Stelo Compare to Other CGMs?

Compared to prescription CGMs like the Dexcom G7 or Libre 3, the Stelo trades some advanced clinical features for simplicity and accessibility. For non-insulin users, it offers everything you need to understand your glucose patterns without the complexity of a full medical-grade system.
