G4 Platinum and G5 Mobile Continuous Glucose Monitoring System Receivers by Dexcom: Class I Recall – Audible Alarm Failure

ISSUE: Dexcom Inc. is recalling the Continuous Glucose Monitoring Systems because the audible alarm may not activate in the receiver piece when low or high glucose levels (hypoglycemia or hyperglycemia) are detected. Relying on this product for notification of low or high blood sugar could result in serious adverse consequences, including death as the auditory alarm may not sound and users might not be notified of low or high blood sugar.

Recalled Devices include (all model numbers and all lot numbers): Dexcom G4 PLATINUM Receiver, Dexcom G4 PLATINUM (Pediatric) Receive, Dexcom G4 PLATINUM (Professional) Receiver, Dexcom G4 PLATINUM Receiver with Share, Dexcom G4 PLATINUM (Pediatric) Receiver with Share, Dexcom G5 Mobile Receiver.

BACKGROUND: The Dexcom Continuous Glucose Monitoring Systems are used to monitor the blood sugar (glucose) level of adult and pediatric patients with type 1 or type 2 diabetes. These glucose monitoring systems include a sensor that is placed under the skin to measure blood glucose readings that are sent to a hand-held receiver. They are

used in combination with standard home glucose monitoring devices in the management of diabetes.
