Dexcom has confirmed the Dexcom G6 continuous glucose monitor (CGM) is entering its final phase. Manufacturing of the sensor will end on July 1, 2026, and although remaining stock will continue to move through pharmacies for a short time, long-term availability isn’t guaranteed. Dexcom will begin shifting users toward its latest sensor, Dexcom G7.

While Dexcom has retired older models in the past, the reaction to the G6 phase-out is noticeably more divided. Thousands of G6 users say the older sensor has better accuracy consistency, and more predictable performance. Others point out that the G6 could be restarted (off-label), while the G7 cannot, making the transition feel more restrictive than previous upgrades.

Dexcom highlights the G7’s updated alert system, redesigned software, and the new 15 Day sensor for those 18 years and older. Although the longer wear time is a major improvement on paper, the company acknowledges some sensors may not reach the full duration. For people who trust the G6, these upgrades don’t always outweigh their concerns about connection and overall reliability.

Many users have taken to social media to share stories of inconsistent readings, early failures, or more frequent troubleshooting. One Reddit user stated “I’ve been on the Dexcom G6 and love it. I’ve heard many bad things about the G7 which is why I haven’t switched… I’m feeling uneasy about having to switch.” It’s clear there is sentiment within the community that Dexcom will need to put at ease.

We reviewed the Dexcom G7 10-day sensor and overall have found the accuracy and connection to be reliable. After its rocky launch, our founder Justin Eastzer says the sensor works well for his needs and nearly all of his devices last the full 10 days. Only time will tell if those who stayed on the G6 feel the same once they transition.

It’s been a tumultuous time for Dexcom, as the company continues to navigate lawsuits, sensor failure reports, and recent recalls. With the G6 approaching its end, the pressure is on Dexcom to deliver consistency, reliability, and most importantly trust with its users.

Dexcom is facing more competition than ever. Abbott’s Freestyle Libre 3 Plus is integrated with most pumps and Medtronic’s Instinct CGM just released. Both offer 15 day wear and support users under the 18 year age requirement the Dexcom 15 Day requires.

Have you transitioned to Dexcom G7 or are you still using the Dexcom G6? Let us know in the comments.
