Which fits the facts I gave?
How to read this
- Prescription (Rx) means a clinician orders it, which is usually what insurance and Medicare require. Over the counter (OTC) means you can buy it yourself.
- Pumps named by maker lists only systems the maker’s page names. “None named” can mean the page did not say, not that it is incompatible.
- Price is the maker’s statement, not a quote from your plan. The finder only compares your budget with prices a maker publishes; devices with no published monthly price stay in the list with a note.
See the over-the-counter CGM guide, Dexcom G7 vs Stelo, FreeStyle Libre 3 Plus vs Dexcom G7, and Medicare coverage. Turn a CGM report into GMI and time in range, and keep notes in the blood sugar log.
Frequently asked questions
Which CGMs can I buy without a prescription?
Dexcom Stelo and Abbott Lingo are sold over the counter, for adults 18 and older who are not on insulin. Abbott’s Libre Rio is FDA-cleared as an over-the-counter CGM, but we could not confirm it is on sale.
Which CGMs are for people who use insulin?
The prescription systems: FreeStyle Libre 3 Plus, Dexcom G7 and G7 15 Day, and Eversense 365. The over-the-counter ones are for people not on insulin.
Does this table rank CGMs?
No. It lists what each maker states, side by side. There is no “best” here, because the right device depends on your treatment, coverage, phone and preferences.
How current is the data?
Each device row was checked against the maker’s own pages on the date shown on its page. Prices and coverage change, so confirm with the maker.
