Dexcom G6
Dexcom
What it is
The 10-day CGM that became the compatibility backbone for many commercial and open-source loops. Dexcom ended G6 manufacturing after 1 July 2026; residual pharmacy or distributor stock may remain and unexpired supplies continue to work with their supported pumps, but availability is no longer guaranteed. The phase-out is not a recall; separate open FDA corrections cover specified receivers and Android app version 1.15.0.

Evidence behind this assessment
Key evidence notes. Study results, product eligibility and access answer different questions.
- Who was studied?
- Study populations and analysis groups vary. Product age limits alone do not describe who was studied.
- Benefit or performance
- Accuracy: Pivotal accuracy was about 9% MARD and enabled non-adjunctive dosing, but newer G7-generation sensors are smaller, have a shorter warm-up, and are more accurate.[3]
- Important harms and treatment burden
- Read the safety discussion and original sources. A missing summary does not establish safety.
- Approval and country access
- Country-specific approval and access are not summarized in this record.Approval, trial recruitment, local supply and funding are separate. Check the cited label or access source.
- Follow-up and remaining uncertainty
- Read the full discussion and original sources for follow-up duration and study limitations.
This record cites company or conference reports. Those sources may describe interim findings; their source type is shown in the source list.
Editorial score: calculation and evidence
A weighted editorial judgment on a 0–100 scale, not a probability of success or a measured treatment effect. Higher criterion scores mean more favorable assessments.
Default calculation: 72 × 20 + 58 × 15 + 92 × 15 + 68 × 10 + 88 × 10 + 82 × 10 + 48 × 10 + 0 × 5 + 8 × 5 = 6590; divide by total weight 100. Unrounded weighted result: 65.9.
Pivotal accuracy was about 9% MARD and enabled non-adjunctive dosing, but newer G7-generation sensors are smaller, have a shorter warm-up, and are more accurate.[3]
A mature interstitial CGM with the usual physiological lag; newer sensors improve start-up and rapid-change performance rather than removing lag.
One of the broadest CGM device ecosystems of its generation, including Omnipod 5, Tandem pumps, iLet, and major open-source loops. That installed-base value persists only while compatible G6 supplies remain.[1]
Mature high, low, urgent-low-soon, sharing, and follower-alert ecosystem, though open FDA corrections cover missed receiver alarms and crashes in Android app version 1.15.0. Affected receivers/apps require the FDA- and manufacturer-specified replacement or update.[4]
Separate reusable transmitter, larger applicator and sensor profile, and a two-hour warm-up make it materially more burdensome than G7.
No ketone sensing — glucose only.
Manufacturing ended after 1 July 2026. Residual stock may remain and Dexcom supports unexpired supplies, but it explicitly cannot guarantee availability and directs users to G7 or G7 15 Day.[1]
The full picture
Dexcom G6 is the legacy sensor that made interoperable automated insulin delivery practical. It delivered factory-calibrated readings for ten days and became a supported input for Tandem, Omnipod 5, iLet, and multiple community-built loops.3 That breadth is why its disappearance matters beyond people using the Dexcom app alone.
The status changed on 1 July 2026. Dexcom says it no longer manufactures the G6 after that date. Pharmacies and distributors may still have stock for a while, and remaining unexpired sensors continue to work with their supported pumps, but Dexcom does not guarantee supply and directs users toward G7 or G7 15 Day.1 Dexcom's second-quarter SEC filing also describes G6 manufacturing as discontinued.2
The manufacturing phase-out itself is not a recall and the sensor did not suddenly stop working. It is a controlled product withdrawal. The practical distinction is important: "supported while unexpired stock lasts" is not the same as an available product a new user can reliably start.
Separate open recalls still matter. FDA's Class I Z-1943-2025 covers named G6 receiver SKUs whose speaker contact can fail, causing missed audible high/low alerts; the action is a serial-number check and free replacement if affected.4 Three same-event Class II receiver records, including Z-1202-2025, cover rare delayed or missed alarms and direct users to reset and update affected receivers.5 Class I Z-0318-2026 is narrower: the US G6/G6 Pro Android app version 1.15.0 can crash and stop readings and alerts, so Dexcom required an app update.6 These are receiver/app corrections, not the reason Dexcom stopped manufacturing G6 sensors.
