Abbott FreeStyle Libre Lawsuit Alleges Recalled Glucose Monitor Led to Inaccurate Readings

Devices were found to generate false low glucose level numbers, putting diabetic consumers at risk of severe and potentially fatal health risks.

A growing number of Abbott CGM lawsuits have emerged following the recall of millions of FreeStyle Libre 3 and Libre 3 Plus glucose monitors, amid reports that inaccurate glucose readings may have contributed to more than half a dozen deaths.

Continuous glucose monitors (CGMs) like the Libre 3 are small devices worn on the upper arm. They continuously track blood sugar levels without the need for regular finger sticks and can be a critical tool for people with diabetes who rely on real-time data to avoid dangerous highs and lows. By showing current levels and trends, the sensors help users adjust medication, food intake and daily activity.

However, in November Abbott announced a FreeSyle Libre 3 and Libre 3 Plus recall following reports of more than 700 serious health events caused by false readings from the sensors, including at least seven deaths. According to the manufacturer, internal testing of FreeStyle Libre 3 units found that some may generate undetected false lows for extended periods. This can mislead users into taking insulin they do not need, increasing the risk of severe hypoglycemia, confusion, loss of consciousness and other life-threatening complications.

The recall impacted approximately 3 million Abbott FreeStyle Libre 3 and Libre 3 Plus sensors in the U.S., about half of which are estimated to have already expired or been used.

In the wake of the recall, Bijoy Shroff filed a complaint (PDF) in the U.S. District Court for the Northern District of California on January 13, seeking class action status for all those who purchased the defective Abbot glucose monitors. The claim is among the first of many Abbott FreeStyle Libre 3 lawsuits expected to be brought after the CGMs were pulled from the market.

According to the lawsuit, Shroff used the recalled glucose sensors and experienced what he describes as dangerously inaccurate glucose readings. The complaint alleges that he remained unaware of the defect until December 3, 2025, when he received a recall notice from CVS alerting him that the devices had been pulled from the market.

Shroff further alleges that Abbott misled consumers about the accuracy and safety of the sensors through deceptive marketing and omissions. The lawsuit claims that he and other customers would not have purchased the devices had they known the sensors were defective and posed a risk of serious injury or death.

“Plaintiff alleges that Abbott knew, or was reckless in not knowing, about the defects at all relevant times, specifically at the time Plaintiff and the other members of the proposed Classes acquired their Sensors or related accessories… required for the Sensors themselves or necessary because of the Sensors’ defects.”

The complaint accuses Abbott of failing to warn about the inaccurate numbers, as well as actively concealing the exclusive knowledge they had about the FreeStyle Libre 3’s deficiencies from consumers, the medical community and federal regulators.

This is at least the second major FreeStyle Libre recall in the last three years. In April 2023, 4.2 million Freestyle Libre glucose monitors were recalled following more than 200 reports of overheating linked to the batteries, resulting in fires and at least one burn injury.

Shroff presents claims of fraudulent omission or concealment, unjust enrichment, violations of the California Consumers Legal Remedies Act and violations of the Florida Unfair Deceptive Trade Practices Act.
