Dexcom recalls G6 glucose monitors that may miss critical high or low blood sugar alarms due to rare software errors. Affected units have specific serial numbers; users should contact Dexcom for guidance.
Under very rare situations, the Dexcom G6 touchscreen receiver may not provide high or low glucose alarms/alerts as designed, which can result in two different conditions. First, if a receiver operating system .net error occurs when an alarm/alert should be triggered, the initial alarm/alert will not be delivered until a subsequent alarm/alert is triggered. At that time, the initial alarm/alert is delivered, but not the second one. Alarm/alerts will continue to be delayed and be one alarm/alert behind, causing delayed alarm/alerts until the receiver is reset. This condition could result in the missed detection of a hyperglycemic or hypoglycemic event. Second, a single EGV reading may be delayed for 5 minutes after the initial .net operating system error. If the user receives a single EGV reading delayed by 5 minutes, the delay is not expected to cause user harm.
Dexcom is recalling its G6 continuous glucose monitors because rare software errors might cause missed alarms for high or low blood sugar. This could lead to undetected dangerous blood sugar levels if the device fails to alert properly.
The device may miss alarms due to rare software errors. When an alarm should trigger, the first alert might not go out until a later alert occurs, and subsequent alarms could be delayed. This could cause undetected high or low blood sugar levels.
People using Dexcom G6 glucose monitors for blood sugar tracking are affected. Those with diabetes who rely on the device for real-time alerts are most at risk.
