Check Your CGM: Recalled FreeStyle Libre 3 Sensors Associated With 7 Deaths

Health care technology company Abbott has recalled certain FreeStyle Libre 3 and FreeStyle Libre 3 Plus continuous glucose monitoring systems because the sensors are displaying incorrect glucose readings that are lower than the body’s actual levels. This could lead to diabetic users making the wrong treatment decisions.

As of Jan. 7, Abbott reported that the recalled sensor has caused 860 serious injuries and been associated with seven deaths. 

On Nov. 24, 2025, Abbott sent a letter to all affected customers about this issue, and the US Food and Drug Administration notified the public on Dec. 2, 2025. Today, the FDA updated its alert to classify it as a Class I recall, meaning that the use of the affected FreeStyle Libre 3 and FreeStyle Libre 3 Plus CGMs could cause serious health consequences or death.

The FreeStyle Libre 3 Plus is on ‘s list of the best continuous glucose monitors, which has been updated to include a note about the recall.
