Dexcom Stelo Review 2026: FDA Clearance, Intended Use and Specs

What is the Dexcom Stelo?

Dexcom Stelo is an over-the-counter device for people aged 2 years and older who do not use insulin, with caregiver supervision below 18. It is not intended for problematic hypoglycemia or dialysis and has no clinical high/low alarms. Platform enrollment may have narrower eligibility. Current FDA clearance K260935 includes a displayed range of 55–350 mg/dL and Direct to Watch; confirm current app rollout and compatible equipment.

Stelo supports up to 15 days of wear under its instructions. Maximum wear is not guaranteed for every sensor and is not a claim that it is the longest-wearing CGM in every category.

Available at CVS, Walgreens, Costco, Amazon, and direct from Dexcom — no doctor visit, no prescription, no prior authorization. Check current stock, delivery estimates and purchase terms with the selected supplier.

The Stelo is not appropriate for people who use insulin. If you take any form of insulin, you need a prescription CGM like the Dexcom G7 or FreeStyle Libre 3.

How accurate is the Stelo?

Published MARD figures come from separate manufacturer studies and do not establish which device is more accurate. Choose a device based on its intended use and the features you need with advice from your healthcare professional, and check manufacturers for current prices.

The Stelo app — built for non-clinical users

Stelo’s intended use and app features differ from G7. Stelo's app shows readings and trends every 15 minutes. FDA says Stelo is not for people with problematic hypoglycemia or on dialysis, and users should consult a health care provider before changing medication based on its output.

Food logging lets you log meals and see your glucose response overlaid directly on your timeline. Over days and weeks, patterns emerge: which meals cause spikes, which produce stable glucose, which are worse in the morning versus evening.

Activity logs may be viewed alongside glucose. Associations do not prove exercise caused a change or establish improved performance; check current app connections with Dexcom.

Stelo's app shows readings and trends every 15 minutes. Check current app insights and educational features with Dexcom; an app explanation does not establish the cause or clinical meaning of a personal glucose change.

How much does Stelo cost?

Check the selected offer’s sensor quantity, price, billing period and commitment terms with Dexcom or the supplier. Stelo supports up to 15-day wear per sensor under its instructions; this does not guarantee a fixed number of sensor changes or continuous readings for a calendar month.

Ask your insurer about device-specific coverage. Ask your plan administrator whether the specific purchase qualifies for HSA/FSA reimbursement. FDA clearance and OTC availability alone do not establish eligibility.
