12/4/2025, 8:49:26 AM
Overview of the Issue
The U.S. Food and Drug Administration (FDA) has issued a warning regarding certain glucose monitoring devices manufactured by Abbott Diabetes Care. The alert concerns the FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors, which have been linked to seven deaths and over 700 serious injuries globally due to inaccurate low glucose readings. As of November 14, Abbott reported 736 adverse events associated with these devices, with 57 incidents occurring in the United States.
Affected Devices
Approximately three million FreeStyle Libre sensors are estimated to be impacted by this issue. The specific models affected include:
- FreeStyle Libre 3 Sensor
- Model Numbers: 72081-01, 72080-01
- Unique Device Identifiers (UDI-DI): 00357599818005, 00357599819002
- FreeStyle Libre 3 Plus Sensor
- Model Numbers: 78768-01, 78769-01
- Unique Device Identifiers (UDI-DI): 00357599844011, 00357599843014
Abbott has indicated that about half of the affected sensors may have already expired or been used.
Health Risks and Consequences
The FDA has classified this situation as a “potentially high-risk issue.” Incorrect low glucose readings can lead patients to make dangerous treatment decisions, such as excessive carbohydrate intake or delaying insulin doses. These actions can result in severe health complications, including diabetic ketoacidosis, heart attack, stroke, kidney damage, and even death.
Official Statements & Responses
Abbott Diabetes Care has confirmed that the manufacturing issue has been identified and resolved, stating, “Abbott has identified and resolved the cause of the issue, which relates to one production line among several that make Libre 3 and Libre 3 Plus sensors.” The company does not anticipate significant supply disruptions and is continuing to produce and ship replacement sensors.
The FDA has advised patients to verify if their sensors are affected and to discontinue use immediately. Patients can check their sensor's serial number through the FreeStyleCheck website to determine if they need a replacement.
Criticism & Opposition
While Abbott has taken steps to address the issue, some critics have raised concerns about the adequacy of the company's response and the potential delay in notifying users about the risks associated with the faulty sensors. The FDA's early safety alert was issued before a formal recall could be determined, prompting questions about the effectiveness of current regulatory measures.
