Two sensors. Thirty continuous days of glucose data. No prescription, no fingersticks, no guesswork.
The Dexcom Stelo is the first FDA-cleared over-the-counter continuous glucose monitor (CGM) available in the United States — and this 2-pack gives you a full month of uninterrupted 24/7 glucose tracking from the company that pioneered continuous glucose monitoring technology 25 years ago.
Each small biosensor applies painlessly to the back of your upper arm and automatically streams glucose readings to the Stelo app every 15 minutes via Bluetooth. You'll see your current glucose level, the direction it's heading, and over time, the patterns that reveal how your food choices, exercise habits, sleep quality, and stress are actually affecting your body. Not in theory — in your own real data.
The Stelo's spike detection feature identifies meaningful glucose rises as they happen, so you can connect cause and effect in real time. Eat a meal and watch your glucose curve. Go for a walk and see it drop. That kind of direct, visual feedback builds understanding faster than any food diary or weekly lab test. The app also generates daily, weekly, and session summaries to help you track progress and build healthier habits over time. Sync Stelo with Apple Health or Google Health Connect to layer your glucose data alongside workouts, steps, and sleep for a complete metabolic picture.
At 15 days per sensor — the longest wear time of any OTC glucose biosensor on the market — each Stelo sensor outlasts the competition. The biosensor is waterproof to 8 feet for 24 hours, so showers, swimming, and workouts are no problem. A 30-minute warmup after application gets you your first reading quickly, and a 12-hour grace period at the end of each session means no abrupt cutoffs. If a sensor fails before its 15 days are up, Dexcom will replace it.
This 2-pack is ideal for anyone with Type 2 diabetes not using insulin, prediabetes, or those simply curious about how their body processes glucose. With 125 million Americans living with Type 2 or prediabetes — many without access to prescription CGMs through insurance — Stelo makes professional-grade glucose intelligence available to anyone who wants it.
Important: The Stelo Glucose Biosensor is intended for adults 18 and older who are NOT currently using insulin. It does not provide low glucose alerts or alarms and is not designed for people with problematic hypoglycemia or those who require real-time alerts to manage dangerous lows. Do not use sensor readings to make medication adjustments without first consulting your healthcare provider.

Reviews
I have been managing Type 2 for eight years and this CGM has taught me more about my blood sugar patterns in two weeks than I learned in years of fingerstick testing. No prescription needed made it so easy to start.
As someone newly diagnosed with prediabetes I wanted to understand how food affects my blood sugar. The Stelo answered all my questions. Wore it for 15 days and completely changed my diet based on what I learned.
The spike alerts helped me identify which foods were causing issues. I eliminated two foods I thought were healthy because of this data. The app is clean and easy to read. 15-day sensor outlasts competitors.
My mother has prediabetes and could not get a CGM through insurance. The Stelo was the perfect solution - no prescription required. The 2-pack gives 30 days of data which her doctor found very useful.
My A1C dropped a full point after implementing what I learned. MDS had the best price and fastest shipping. Will be ordering the next 2-pack very soon.
