FDA OKs Dexcom G7 15-Day Continuous Glucose Monitor

Dexcom has received U.S. Food and Drug Administration (FDA) clearance for the G7 15-day continuous glucose monitoring (CGM) system for adults with diabetes.

According to the company, it’s the longest lasting CGM system with 15.5 days of wear. It boasts an overall MARD (mean absolute relative difference) of 8% and easier glucose management with fewer monthly sensors and reduced monthly waste.

Dexcom said it’s working with its insulin pump partners to make sure the G7 15-day will be compatible with automated insulin delivery (AID) systems upon its launch. G7 is currently compatible with the Omnipod 5 AID and t:slim X2 insulin pump.

The rollout is anticipated in the U.S. in the second half of 2025.

“Dexcom G7 15 Day makes managing diabetes even easier with its extended wear and greater accuracy,” said Satish Garg, MD, from Barbara David Center for Diabetes at the University of Colorado School of Medicine. “Data recently released during the 18th international Advanced Technologies and Treatments for Diabetes conference in Amsterdam supports that G7 15 Day is the most accurate CGM for adults.”

The 15-day version touts the same G7 features like being waterproof, connection to the Apple Watch, automated activity logging, simplified meal logging, a 12-hour grace period to replace finished sensors, and much more.

“The approval of Dexcom G7 15 Day marks another major innovation for Dexcom,” said Jake Leach, executive VP and chief operating officer at Dexcom. “By listening to the needs of our users, we’re proud to offer the longest lasting wearable and most accurate CGM, giving people the knowledge to better control their diabetes with our best-in-class technology. This milestone sets a new standard in CGM and is a testament to our continued leadership in glucose biosensing. We look forward to bringing it to market in the second half of this year, but in the meantime, we encourage our users to upgrade to our current G7 system to gain the benefits of the most connected CGM brand in the world.”
