Recall Insight

This recall's affected scope (see the Recall Profile below) is large enough to require multi-state distribution tracking. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.

Within the same product category the archive holds 6 closely related recalls, 6 from FDA Devices - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.

Product description

Brand Name: Dexcom G7 Continuous Glucose Monitoring System Product Name: Dexcom G7 CGM Android App Model/Catalog Number: SW12299 Software Version: version 2.8.0 and earlier Product Description: Dexcom G7 CGM Android App SW12299 Component: Dexcom G7 Continuous Glucose Monitoring System

Reason for recall

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.
