Dexcom has issued a recall for specific models of continuous glucose monitoring receivers due to speaker malfunctions that can hinder alert notifications for crucial blood sugar levels. Since May 2025, there have been 112 global complaints linked to these issues, resulting in 56 reported injuries. The affected models include the Dexcom G6, G7, One, and One Plus receivers, with the latter two being available outside the U.S. Continuous glucose monitors (CGMs) are vital for diabetes management, helping users track their glucose levels in real-time. Failure to receive audio alerts may lead to severe health risks, including symptoms of hypoglycemia or hyperglycemia, representing a significant concern for users reliant on these devices.
While Dexcom has clarified that even though the audio alert function may be compromised, users can still receive alerts through vibration and visual prompts, this is less effective when devices are often kept out of sight in pockets or bags. Additionally, users relying on the mobile app will continue to receive uninterrupted access to glucose values, alerts, and alarms, providing a crucial backup to the receiver’s malfunction. Nonetheless, the risk of not noticing critical alerts persists due to the potential for the audio alerts to be the primary mode of notification during emergencies.
For those affected, Dexcom urges users of continuous glucose monitors to verify whether their device is part of the recall by checking the model and serial numbers located on the back of the receiver. It’s essential to act quickly; if a user finds their device is affected, they are advised to contact Dexcom for a free replacement. Given the importance of continuous monitoring for diabetes management, it’s critical for those dependent on these devices to order their replacements without delay, especially since relying on the malfunctioning device may pose severe risks.
Users should routinely test their receiver’s speaker functionality, especially during the charging process. The receiver will display a Speaker Test screen when it is plugged in, providing instructions for ensuring that the sound is working properly. If the speaker fails to beep, immediate contact with Dexcom is necessary. This procedure should not be limited to a single test, as repeated checks can help users ensure that the device remains operational over time, thereby mitigating the risk of unexpected speaker failures.
In the meantime, maintaining awareness of the potential issues with the speaker will help users act decisively when monitoring blood sugar levels. Dexcom recommends that all users of their CGMs follow these testing protocols, regardless of whether their device is currently under recall. Making speaker testing a routine part of device maintenance could significantly reduce the chances of missing critical alerts in the future.
