Glucose Monitor Recall: Dexcom G7 US Retail Sensor/Transmitter
Announced 2026-07-01 · FDA
The recall affects the Dexcom G7 CGM System and Dexcom ONE+ CGM System apps on iOS, watchOS, and Android, versions 2.8.0 or earlier and 1.4.0 or earlier respectively. The affected app does not provide the expected 'Sensor Failed' alert when the transmitter reports a 'transmitterFailed' error, and instead ends the sensor session and may show 'Start Sensor' or 'No active sensor' without alerting the user. The recall has worldwide distribution, including US nationwide, and lists Lot Code: UDI SW12300 - 00386270001863.

| Product | Brand Name: Dexcom G7 Continuous Glucose Monitoring System Product Name: Dexcom G7 CGM iOS App Model/Catalog Number: SW12300 Software Version: version 2.8.0 and earlier Product Description: Dexcom G7 CGM iOS App Component: Dexcom G7 Continuous Glucose Monitoring System |
| Reason | The affected devices are the Dexcom G7 Continuous Glucose Monitoring System (CGM System) using iOS, watchOS and Android App software (versions 2.8.0 or earlier) and Dexcom ONE+ CGM System using iOS and Android App software (versions 1.4.0 or earlier), henceforth referred to as the App. The affected App does not provide an expected "Sensor Failed" alert when the transmitter sends a "transmitterFailed" error message to the App when the CGM experiences a hardware or firmware failure. Instead, the App ends the CGM sensor session, stops reporting glucose values and displays the Start Sensor screen or No active sensor message without alerting the user, which can lead to missed detection of a hyperglycemic or hypoglycemic event and a delay in treatment. |
