Dexcom is recalling (Class 1 device correction) its Dexcom G7 App and Dexcom ONE+ App which contain a software design error that leads to a missed “sensor failed” alert when the sensor’s transmitter encounters a hardware/firmware failure. Affected apps end the continuous glucose monitoring sensor session, stops reporting glucose values, and displays the “start sensor” screen or “no active sensor” messages without alerting user, according to a [recall notice](https://www.fda.gov/medical-devices/medical-device-recalls/continuous-glucose-monitor-apps-correction-dexcom-inc-issues-correction-g7-apps-and-one-apps-due?utm%5Fmedium=email&utm%5Fsource=govdelivery). 

“The failure to alert the user of a failed transmitter may result in the user being unaware of extended periods of missed glucose data, notifications, alerts and alarms, which may result in a delay in treatment of prolonged episodes of severe hypoglycemia or hyperglycemia,” the alert says. Using affected devices may cause serious adverse health consequences, including hypo/hyperglycemia and death, it adds. To date, no injury reports have been received.

The devices are intended to provide real-time, continuous glucose monitoring for managing diabetes in persons 2 years and older.
