Over-the-Counter CGM Pricing: No Prescription Costs in 2026
OTC CGM Pricing Summary
Over-the-counter continuous glucose monitors offer straightforward pricing with no insurance involvement. The Dexcom Stelo costs $49 to $99 per month for 2 sensors (15 days each). The Abbott Lingo costs $49 per month for 2 sensors (14 days each). The Abbott Libre Rio costs $49 per month for 2 sensors (14 days each). These prices include the sensor hardware and access to the companion smartphone app. There are no separate transmitter costs, no additional fees for app access, and no hidden charges. SIBIONICS CGM is available in international markets at $30 to $60 per month but is not yet available in the United States.

Where to Buy OTC CGMs
OTC CGMs can be purchased through manufacturer direct-to-consumer websites, Amazon, major retail pharmacies (CVS, Walgreens, Walmart), and select grocery store pharmacies. Online ordering from the manufacturer website is typically the most convenient option, with automatic subscription delivery available for Dexcom Stelo and Abbott Lingo. Multi-month subscription commitments from some manufacturers offer 10 to 20% discounts on the per-month price. No prescription, doctor visit, or age verification beyond confirming you are 18+ is required to purchase any OTC CGM.
OTC vs Prescription Cost Comparison
The cost comparison between OTC and prescription CGMs depends entirely on insurance status. With commercial insurance, a prescription CGM like the FreeStyle Libre 3 Plus costs $15 to $30 per month — significantly less than any OTC option. Without insurance, the same Libre 3 Plus costs $75 to $150 per month, making OTC CGMs ($49) the more affordable choice. The key insight: if you have diabetes and insurance coverage, a prescription CGM is almost always cheaper. If you do not have a diabetes diagnosis or insurance coverage for a CGM, OTC is the more affordable and accessible path to continuous glucose monitoring.
OTC CGM Price Per Day: The True Daily Cost
Breaking OTC CGM costs to a daily rate provides useful perspective: the Dexcom Stelo costs $1.63-3.30/day, the Abbott Lingo costs $1.63/day, and the Abbott Libre Rio costs $1.63/day. For comparison, a daily coffee costs $4-6, a gym membership averages $1.50-3.00/day, and a fingerstick glucose meter with 4 daily test strips costs $1.00-2.50/day. On a per-data-point basis, OTC CGMs are dramatically cheaper — they produce 288 glucose readings per day versus 4 fingerstick readings, making the cost per reading approximately $0.006-0.011 for CGM versus $0.25-0.63 for fingerstick testing.
