What Is the FreeStyle Libre Lawsuit?
The FreeStyle Libre sensor lawsuit alleges that faulty Libre 3 or Libre 3 Plus glucose monitor sensors provided inaccurate high or low glucose readings that led to serious injury or death.
These claims are built on the FDA’s early alert and recall communications, which stated that certain Libre 3 and 3 Plus sensors for people with diabetes can provide incorrect glucose readings. In addition, Abbott, the manufacturer of the monitors, reported 736 serious injuries and seven deaths linked to incorrect readings as of November 2025.
“Manufacturers should be responsible for the harm their defective products inflict on their customers,” said Ellen Relkin, partner and chair of Weitz & Luxenberg’s Drug and Medical Device Litigation practice group.
Abbott is the main defendant in these claims. The FreeStyle Libre sensor lawsuit seeks compensation for medical bills, lost income and pain and suffering. Wrongful death cases also seek losses suffered by surviving family members.
“Manufacturers should be responsible for the harm their defective products inflict on their customers.”
Who Qualifies for a FreeStyle Libre Lawsuit?
You may qualify for a FreeStyle Libre lawsuit if you or a loved one used a recalled or allegedly defective FreeStyle Libre 3 or Libre 3 Plus sensor and then suffered serious glucose‑related injuries that can be tied to inaccurate readings or missed alerts.
Law firms screen for specific devices, time frames, medical events and supporting documentation before accepting cases.
Qualifying Devices and Ages for FreeStyle Libre 3 and Libre 3 Plus
Both adults and children may qualify for a FreeStyle Libre 3 and Libre 3 Plus lawsuit because people as young as 2 years old can use these devices. Libre 2 and earlier Libre CGMs aren’t currently included in these lawsuits.
Some firms may focus on specific lots listed in recall and medical device correction notices. Since millions of Libre 3 devices were affected by Abbott’s medical device correction and recall, millions of people may have been affected.
Qualifying Injuries in FreeStyle Libre 3 and Libre 3 Plus Lawsuits
Qualifying FreeStyle Libre 3 or Libre 3 Plus sensor injuries are related to complications of high or low glucose from inaccurate sensor readings.
- Central nervous system dysfunction
- Coma
- Confusion or altered mental state
- Death
- Diabetic ketoacidosis
- Emergency medical treatment or hospitalization
- Loss of consciousness
- Permanent neurological damage
- Seizures
- Severe hypoglycemia
This list of injuries isn’t all-inclusive. Make sure to talk to an attorney to determine if your injury qualifies for a FreeStyle Libre 3 lawsuit.
Documentation and Evidence To Support a FreeStyle Libre Lawsuit
Strong documentation is critical to connect a specific sensor defect to the injury and to strengthen your FreeStyle Libre lawsuit.
- Device and product information: The physical Libre 3 or Libre 3 Plus sensor(s), reader and packaging, with visible serial numbers, lot numbers and expiration dates. Screenshots or exports from the Libre app or reader showing glucose logs, alarms and any error messages around the time of the event.
- Medical records: Hospital and ER records documenting diabetic ketoacidosis, severe hypoglycemia, seizures, coma, cardiac events or other complications. Outpatient endocrinology and primary-care records showing diabetes history, insulin regimen, CGM use and providers’ observations about the device’s performance. Lab values showing glucose levels and any physician's notes are also helpful.
- Personal and witness evidence: Written timelines or journals describing symptoms, CGM readings, insulin/carbohydrate decisions and how the injuries unfolded. Statements from family members or caregivers who observed alarms (or their absence), device problems or the emergency episode.
- Regulatory and manufacturer materials: FDA alerts, recall notices and Abbott press releases tying the claimant’s sensor model and lot to known accuracy problems. Any prior complaint numbers or reports filed with the FDA’s MedWatch or Abbott customer support about that sensor.
Firms also frequently work with experts to interpret this evidence, compare CGM data with lab readings and provide their opinion on whether a sensor defect likely caused or contributed to the injury.
Types of FreeStyle Libre Lawsuits and Class Actions
There are two main types of FreeStyle Libre lawsuits: individual injury lawsuits and consumer‑oriented class actions.
Injury claims seek compensation for serious physical, mental and emotional harm to individuals who used the FreeStyle Libre 3 or Libre 3 Plus.
The FreeStyle Libre 3 and Libre 3 Plus class action lawsuit filed in California claims that Abbott committed fraud by concealing problems with the devices. These plaintiffs want refunds for the purchase price of the devices.
Plaintiff’s Freestyle Libre Class Action Story
In the Libre 3 and Libre 3 Plus class action lawsuit, plaintiff Bijoy Shroff claimed he relied on FreeStyle Libre 3 and Libre 3 Plus sensor readings to manage his diabetes. He stated that he trusted Abbott’s marketing and advertising materials, which represented the sensors as safe and reliable.
However, he experienced dangerously inaccurate glucose readings while using these sensors. He later received a letter dated Dec. 3, 2025, from CVS informing him that his sensors were identified as defective and subject to a recall.
FreeStyle Libre 3 Recall Information and Safety Alerts
Two main FDA safety alerts related to these sensors are the 2024 Libre 3 recall and the 2025 medical device correction for Libre 3 and Libre 3 Plus sensors. These actions were for dangerously high or low glucose readings.
July 2024: Abbott flagged a small number of FreeStyle Libre 3 Sensors for providing incorrect high glucose readings and issued a recall. Incorrect readings can prompt patients to over-deliver insulin, leading to a hypoglycemia crisis that may cause central nervous system dysfunction, loss of consciousness or seizure activity. These can lead to coma, permanent neurological damage and death.
November 2025: Abbott issued an urgent medical device correction for FreeStyle Libre 3 and Libre 3 Plus, affecting about 3 million devices. The devices could provide incorrect low glucose readings, and the company reported 736 serious injuries and seven deaths associated with the sensors.
Affected Libre 3 and Libre 3 Plus Devices
The FDA recall and Abbott medical device correction only apply to certain Libre 3 and Libre 3 Plus devices. These don’t affect other FreeStyle Libre devices, such as the Libre 2 or Libre 2 Plus.

How To Check for Your Serial Number
Patients can check their app or the device package for FreeStyle Libre 3 serial numbers. Instructions for navigating your app may vary depending on the model and device.
- In the FreeStyle Libre 3 app, select “About Screen” from the Main Menu. Locate the sensor serial number under “Last 3 Sensors.”
- In the Libre app, go to the bottom Menu and select Profile, then go to About. Locate the sensor serial number under “Last 3 Sensors.”
- In the FreeStyle Libre 3 Reader, go to Settings Menu and select “System Status,” then “System Info.”
The FDA also included step-by-step instructions with images of app interfaces that you can reference.
What To Do If Your FreeStyle Libre Sensor Is Part of a Recall
If your FreeStyle Libre sensor is part of the recall, the FDA recommends that you stop using it and dispose of it right away. Talk to your diabetes care team about your options for a replacement.
In the meantime, use a backup method to track your blood sugar, such as a blood glucose meter with fingersticks. If you or a loved one were seriously harmed by inaccurate glucose readings, you may want to contact a lawyer to pursue legal action.
Potential FreeStyle Libre Lawsuit Settlement Amounts
Libre 3 and Libre 3 Plus lawsuits are still in early stages. No global settlement program has been announced, so it’s difficult to predict potential FreeStyle Libre lawsuit settlement amounts.
Factors That May Affect FreeStyle Libre Settlement Values
Several case‑specific and litigation‑wide factors are likely to drive potential settlement ranges in FreeStyle Libre 3 and Libre 3 Plus lawsuits.
- Severity and type of injury: More serious injuries that require hospitalization or lead to long-term complications or disability usually increase both economic and non-economic damages.
- Strength of causation evidence: Key evidence includes CGM downloads aligned with lab glucose values, hospital records and recall documentation tying the sensor’s lot to the defect.
- Age, income and life impact: Younger plaintiffs, wage earners and caregivers may see larger projected losses in future earnings, household services and lifetime medical costs. This can increase settlement value. Courts and insurers also consider permanent limitations, loss of independence and quality-of-life changes.
Allegations that a plaintiff ignored CGM instructions or had poorly controlled diabetes can reduce potential settlement value.
Types of Compensation in FreeStyle Libre Lawsuits
FreeStyle Libre 3 claims generally follow the same damages framework as other defective medical device cases. These include a variety of damage types, such as economic, non-economic and punitive claims.
- Economic damages: Past and future medical expenses for treating glucose-related injuries, lost wages, and lower earning capacity if injuries caused missed work, job loss or long-term disability.
- Non-economic damages: Pain and suffering, emotional distress, loss of enjoyment of life and loss of independence or activities the person can no longer perform. In spouse or family claims, loss of consortium or loss of society/companionship is also included.
- Wrongful-death damages: Funeral and burial costs, loss of the decedent’s financial support and services, and loss of love, guidance and companionship for surviving family members. These apply only when a FreeStyle Libre-related event is alleged to have caused death.
- Punitive damages: When cases go to trial, punitive damages may be sought if plaintiffs can show egregious misconduct — such as knowingly selling defective sensors or unreasonably delaying safety actions — though courts often scrutinize and limit these awards.
Consumer class actions are focused on economic loss and recalls and generally do not involve personal‑injury damages. It’s more typical for them to seek refunds, price‑premium damages and relevant out‑of‑pocket costs.

Steps To Take if You Were Injured by a FreeStyle Libre 3 or Libre 3 Plus Sensor
If you believe a FreeStyle Libre 3 or Libre 3 Plus sensor caused DKA, severe hypoglycemia or another serious event, you should focus on your safety, document your injuries and contact a lawyer to learn about your legal options.
- Medical steps: Get immediate medical care. Tell providers you were using a Libre 3 or 3 Plus CGM, get lab glucose values and make sure complications (DKA, seizures, coma, etc.) are clearly documented in your chart. Follow your diabetes team’s instructions for switching monitoring methods.
- Preserve evidence: Keep the sensor, reader and packaging, including serial and lot numbers, instead of throwing them away. Save screenshots or downloads of Libre readings and alarm history around the event time.
- Get medical records: Request copies of hospital, ER and clinic records for the incident, including admission notes, labs, imaging and discharge summaries. Write a timeline describing your symptoms, sensor readings and treatment decisions.
- Check serial numbers: Check whether your sensor’s serial number is part of the Libre 3 and Libre 3 Plus recall or “medical device correction” using Abbott’s FreeStyleCheck website or recall notices.
- Contact a law firm: Get a free, no-obligation case review from a law firm investigating Libre 3 cases once your immediate medical issues are stabilized.
Most FreeStyle Libre claims are handled by product‑liability or defective medical device firms on a contingency‑fee basis. This means there are no upfront costs unless your lawyer gets a settlement or jury verdict for you.
Statutes of Limitations for FreeStyle Libre Lawsuits
There is a time limit to file your FreeStyle Libre lawsuit, known as a statute of limitations. Depending on the state you live in, the statute of limitations (SOL) for personal injury and wrongful death cases can be different.
This limit often ranges from about one to six years from the date of injury, diagnosis, death or “discovery” that the sensor may have caused the harm. Contact an attorney to determine the exact time limit for your individual case.
