Dexcom Recalls Over 2 Million CGM Receivers Due to Alarm Failure

Dexcom has recalled more than 2 million continuous glucose monitor (CGM) receivers after discovering a speaker issue that may prevent audible alerts for high or low blood sugar. The Class I recall, the FDA’s most serious, affects G7, G6, One, and One+ models. The malfunction, caused by defective foam or assembly errors, can lead to missed alerts, potentially resulting in severe events like seizures or loss of consciousness—56 such cases have been reported, with all patients recovering.

The issue does not affect Dexcom users who rely on mobile apps, which most do. Impacted users are advised to check their receivers, return affected units, and request free replacements. The company urged regular speaker checks and began the recall on May 12, 2025.
