Class I U.S. Food and Drug Administration

Brand Name: Dexcom G7 Continuous Glucose Monitoring System Product recall: The affected devices are the Dexcom G7 Continuous Glucose Monitoring System

Recall published 1+ years ago

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.

The hazard: Device safety concern

This is a device enforcement record. Check whether the remedy is a correction, a software update or a removal before changing anything.

Why it matters: The FDA recorded an enforcement action against this device. Most device recalls are corrections rather than removals, so the device often stays in use while the manufacturer issues a fix.

  • Contact the distributor or clinic named on your paperwork and quote the recall number on this page. They will tell you whether the remedy is a repair, a replacement or an instruction update.
  • If the device was billed to insurance or Medicare, the replacement is usually billed the same way; you should not face a second deductible for a recall.
