Dexcom Stelo Review: Is the OTC CGM Worth It in 2025?
If you've been curious about continuous glucose monitoring but don't have a prescription — or simply want a more accessible option — the Dexcom Stelo may have caught your attention. As the first FDA-cleared over-the-counter (OTC) CGM available in the United States, the Stelo represents a significant shift in how people can monitor their blood sugar. But is it the right choice for you in 2025? Let's break it down.
What Is the Dexcom Stelo?
The Dexcom Stelo is a continuous glucose monitor designed specifically for adults with Type 2 diabetes who do not use insulin, as well as those who are prediabetic or health-conscious individuals who want insight into how food, exercise, and lifestyle affect their glucose levels.
Unlike the Dexcom G7 or G6 — which require a prescription and are designed for insulin-dependent users — the Stelo is available without a prescription at pharmacies and authorized online retailers. You simply purchase it, apply the sensor to the back of your arm, and start reading your glucose data through the Dexcom Stelo app.
Key Features of the Dexcom Stelo
- 10-day wear time per sensor
- No fingerstick calibration required
- Readings every 15 minutes, sent directly to your smartphone
- Compatible with iOS and Android devices
- Simple, user-friendly app with trend arrows and meal tracking
- Water-resistant (up to 8 feet for 24 hours)
- Available OTC — no prescription needed
The sensor design is compact and sits comfortably on the upper arm. Most users report minimal discomfort during insertion, and the adhesive holds well throughout the 10-day wear period.
Who Is the Dexcom Stelo For?
The Stelo is not recommended for people who take insulin or who experience frequent episodes of hypoglycemia (low blood sugar). It doesn't have low glucose alerts, which is a critical safety feature for insulin users.
However, it's a strong option for:
- Adults managing Type 2 diabetes with oral medications or GLP-1s
- People with prediabetes looking to understand their glucose patterns
- Anyone interested in metabolic health tracking
- Caregivers helping loved ones monitor glucose without clinical visits
If you fall into any of these categories and want a non-invasive way to track glucose trends throughout the day, the Stelo offers real value.
Accuracy and Performance
Dexcom has long been regarded as a leader in CGM accuracy, and the Stelo maintains that reputation. In clinical trials, the Stelo demonstrated strong performance compared to laboratory glucose measurements. The Mean Absolute Relative Difference (MARD) — the standard metric for CGM accuracy — showed results consistent with other Dexcom devices.
Real-world users in 2025 continue to report reliable readings with few sensor failures. As with any CGM, occasional compression lows (inaccurate low readings when sleeping on the sensor) can occur, but these are generally short-lived.
Cost Breakdown
Each Stelo package includes 2 sensors (covering 20 days of wear) and retails for approximately $99. That works out to roughly $4.95 per day of glucose monitoring — a cost that many users find reasonable compared to frequent clinic visits or test strip expenses.
The Stelo is FSA and HSA eligible, which can significantly reduce your out-of-pocket cost if you have a flexible spending account. You can explore CGM options, including Dexcom products, through MDS Diabetes' CGM category, where pricing and availability are clearly listed.
What Users Are Saying in 2025
Feedback from users and caregivers has been largely positive. Common highlights include:
- Ease of setup — most users are up and running within 30 minutes
- Actionable insights — seeing glucose spikes after meals motivates healthier choices
- Peace of mind — especially for caregivers monitoring elderly parents with Type 2 diabetes
The most common criticism is the 15-minute reading interval, compared to the 5-minute interval on the Dexcom G7. For non-insulin users, this is generally not a safety concern, but some users prefer more frequent updates.
Is the Dexcom Stelo Worth It in 2025?
For the right user, absolutely yes. If you have Type 2 diabetes managed without insulin, are prediabetic, or simply want to understand how your lifestyle affects blood sugar, the Dexcom Stelo is one of the most accessible and reliable tools available today.
It fills an important gap in the market — delivering clinical-grade glucose monitoring without the barriers of a prescription or physician visit. Many healthcare providers at clinics like MDS Diabetes recognize the Stelo as a meaningful step toward empowering patients with real-time data.
That said, always consult your healthcare provider before making changes to your diabetes management plan based on CGM data.
