Caution: Abbott glucose sensor recall
Abbott glucose sensors are under recall after a manufacturing issue linked to deaths and injuries.
The recall affects certain FreeStyle Libre 3 and Libre 3 Plus sensors because they may provide falsely low glucose readings. This can lead to incorrect treatment decisions, such as consuming too many carbohydrates or skipping insulin doses. Such errors can result in serious health risks, including injury or death. The issue stems from a manufacturing defect on a single production line. Abbott estimates that approximately 3 million sensors in the U.S. are affected, though about half may have already expired or been used. The company has stated that they have resolved the manufacturing issue and do not expect significant supply disruptions. As of November 14, 2025, Abbott reported 736 serious adverse events globally, including 57 in the U.S., and seven deaths outside of the U.S. potentially linked to the issue. One U.S. death has been linked by the family to the faulty sensors, but is not included in Abbott's official count. If you use these sensors, check if yours are affected at www.FreeStyleCheck.com. If confirmed, immediately stop using the sensor and request a replacement. When readings don't match symptoms, verify with a blood glucose meter.
