Is There a Class Action Against FreeStyle Libre? (2026 Update)
As of 2026, there is no certified class action against Abbott Diabetes Care over the FreeStyle Libre; the claims filed so far are individual injury claims. There is no announced global class-action settlement amount yet, and the answer to “how much is the FreeStyle Libre lawsuit worth per person?” depends entirely on the severity of the injury and the strength of the device and medical documentation. Cases involving hospitalization, lasting injury, or wrongful death typically carry the highest individual values.What is happening right now: reports of inaccurate sensor readings continue to surface across the FreeStyle Libre, Libre 2, Libre 3, and Libre 3 Plus product lines. The FDA’s MAUDE database continues to log adverse-event reports tied to the FreeStyle Libre system, and Abbott has issued multiple recalls and safety communications related to the product family over the years.

Update: A Product Liability Complaint Has Been Filed (July 2026)
On April 21, 2026, a product liability complaint was filed in the U.S. District Court for the Eastern District of Louisiana — Connoly v. Abbott Diabetes Care Inc., et al., No. 2:26-cv-00840 — alleging that a FreeStyle Libre 2 sensor showed a falsely normal reading while the plaintiff was in diabetic ketoacidosis (DKA), a life-threatening condition. The complaint alleges the plaintiff’s sensor read 167 mg/dl shortly before a hospital measured her actual blood sugar at approximately 700 mg/dl.The complaint is captioned as a class action, but as filed it pleads only individual claims under the Louisiana Products Liability Act and does not include Rule 23 class-certification allegations — consistent with this investigation’s assessment that FreeStyle Libre claims are more likely to proceed as individual injury claims or a mass tort than as a certified class action. Read the full breakdown, including the embedded complaint, on OpenClassActions.com’s coverage of the filed complaint. These remain unproven allegations.
What Is the FreeStyle Libre Lawsuit About? (Recall, Side Effects & Inaccurate Readings)
The FreeStyle Libre is a flash/continuous glucose monitor (CGM) manufactured by Abbott Diabetes Care, a division of Abbott Laboratories. The system uses a small sensor worn on the back of the upper arm that measures glucose in interstitial fluid and sends readings to a reader device or a paired smartphone app. Abbott has sold the product in multiple generations — FreeStyle Libre, FreeStyle Libre 2, FreeStyle Libre 3, and FreeStyle Libre 3 Plus — and it is one of the most widely used CGMs in the world for people living with Type 1 and Type 2 diabetes.The claims at issue come from patients and families who allege that a FreeStyle Libre sensor gave a seriously inaccurate glucose reading — either falsely low or falsely high — which led them to take the wrong dose of insulin, skip insulin that was needed, or eat glucose they did not need. The downstream injuries alleged in the investigation include severe hypoglycemic episodes (blood-sugar crashes, loss of consciousness, seizure), severe hyperglycemia, diabetic ketoacidosis (DKA), emergency-room visits and hospitalization, permanent cognitive impairment from prolonged low blood sugar, and in the worst cases, death.
The U.S. Food and Drug Administration has issued multiple safety communications, MAUDE adverse-event entries, and recalls related to the FreeStyle Libre product family over the years. The central question in any such claim is whether Abbott’s sensor design, manufacturing, and post-market surveillance adequately protected users from reasonably foreseeable injury.
Which FreeStyle Libre Devices Are Involved?
The investigation covers the full FreeStyle Libre CGM product family sold in the United States, including:• FreeStyle Libre (original flash glucose monitoring system)
• FreeStyle Libre 2 (added real-time Bluetooth alarms)
• FreeStyle Libre 3 (smaller sensor, continuous real-time readings to smartphone)
• FreeStyle Libre 3 Plus (extended 15-day wear with continuous readings)
Readers, smartphone apps, and integrated insulin-pump systems that rely on FreeStyle Libre sensor data may also be relevant to your claim.
FreeStyle Libre Side Effects and Sensor Failures Reported
The following FreeStyle Libre side effects and sensor-failure outcomes have been reported by users and are being evaluated in the investigation. Many are tied to the FreeStyle Libre 3 and Libre 3 Plus, where users have described problems including the sensor showing “sensor error,” reading falsely high or falsely low for hours, dropping out intermittently, or simply failing well before its 14- or 15-day life:• Severe hypoglycemia — loss of consciousness, seizure, fall-related injury, or permanent cognitive impairment caused by blood sugar dropping dangerously low after the sensor read falsely high and the patient dosed insulin they did not need.
• Severe hyperglycemia and diabetic ketoacidosis (DKA) — life-threatening acid build-up in the blood caused by prolonged high glucose after the sensor read falsely low and the patient either skipped insulin or under-dosed.
• Emergency-room visits and inpatient hospitalization for either of the above.
• Long-term complications — anoxic brain injury, kidney damage, cardiac events, and other sequelae of repeated glycemic crises.
• Wrongful death — families who lost a loved one following a FreeStyle Libre reading error may qualify to file a claim on the decedent’s behalf.
Who a FreeStyle Libre Claim Might Involve
A FreeStyle Libre injury claim generally involves someone who or a loved one used a FreeStyle Libre sensor (Libre 1, 2, 3, or 3 Plus), experienced a significantly inaccurate or failed reading, and suffered one or more of the injuries listed above that required medical attention. Stronger claims typically involve:• A documented medical event — ER record, hospital admission, ambulance run sheet, or a physician note tying the event to the FreeStyle Libre reading.
• Device evidence — the sensor itself (if preserved), sensor lot/serial number, reader/app export of the glucose trace, and the time-stamped reading that led to the insulin dose or missed dose.
• Proof of use — pharmacy records, insurance claims, or receipts showing you were prescribed and actively using the FreeStyle Libre system at the time of the event.
• Injury documentation — follow-up records showing the severity of the hypoglycemic or hyperglycemic event and any lasting harm.
Not every claim has every item, but this is the documentation such a claim generally rests on.
How Much Is the FreeStyle Libre Lawsuit Settlement Worth Per Person?
There is no fixed FreeStyle Libre settlement amount at this stage — injury claims are evaluated individually. If a claim succeeds, compensation may include medical bills (past and future), lost wages, pain and suffering, loss of consortium, and, in wrongful-death claims, funeral expenses and loss of financial support. Punitive damages may also be available where a manufacturer’s conduct is found to be especially egregious. The actual value of any individual FreeStyle Libre lawsuit per person depends on the severity of the injury, the strength of device and medical documentation, and the jurisdiction where the claim is filed.How a FreeStyle Libre Lawsuit Generally Proceeds
1. Check the criteria. Compare your own facts against the eligibility criteria above — the sensor generation you used, the reading that failed, and the injury that followed.2. Legal review. Medical-device injury cases are typically handled by product liability attorneys on contingency; OpenClassActions.com does not refer cases and is not a law firm.
3. Preserve evidence. Do not throw away the sensor, reader, or packaging if you still have it. Save glucose-trace exports from the app. Request a copy of your medical records.
4. Claim evaluation. If your case moves forward, your attorney will build the claim, obtain the records, and pursue compensation through the appropriate court or settlement process.
