Experienced Medical Device Attorneys Fighting for Diabetics  

McCune Law Group is accepting cases from individuals who have suffered harm due to malfunctioning Abbott FreeStyle Libre 3 and FreeStyle Libre 3 Plus continuous glucose monitoring devices. For nearly two decades, our firm has held medical device manufacturers accountable when their products put patients at risk. 

We bring deep experience in pharmaceutical litigation, product liability, and medical malpractice, and we understand that when you’re managing diabetes, you trust your life to these devices. When they fail, the consequences can be devastating. 

Two Separate Recalls: Dangerous Sensor Errors Put Diabetics at Risk 

Two Critical Manufacturing Issues: 

July 2024 Recall: Falsely HIGH Glucose Readings 

Abbott Diabetes Care has acknowledged serious manufacturing issues affecting approximately 3 million FreeStyle Libre 3 sensors. These issues have caused life-threatening complications for people with diabetes who depend on accurate glucose readings to make critical treatment decisions. 

• Sensors displayed artificially elevated blood sugar levels
• Caused dangerous hypoglycemic episodes (dangerously low blood sugar)     
• Resulted in seizures, loss of consciousness, and hospitalizations 

November 2025 Recall: Falsely LOW Glucose Readings 

• Sensors displayed artificially lowered blood sugar levels 
• Led to dangerous hyperglycemic episodes and diabetic ketoacidosis 
• Resulted in emergency interventions and serious complications 

By The Numbers: 

As of February 2026, there have been: 

• 3 million defective sensors affected from a single production line 
• Over 860 serious injuries reported to the FDA 
• 7 deaths linked to sensor failures worldwide 

The FDA has warned that these inaccurate readings can lead to incorrect treatment decisions with potentially fatal consequences. If you relied on a FreeStyle Libre 3 sensor for your diabetes management, you need to know your rights. 

Serious Health Risks from Inaccurate Glucose Readings 

When you have diabetes, accurate glucose monitoring isn’t just important—it’s essential to your survival. Inaccurate readings from a defective continuous glucose monitor can trigger a cascade of serious health complications. 

Immediate Health Risks: 

From Falsely High Readings (Leading to Excessive Insulin): 

• Severe hypoglycemia (blood sugar drops too low)
• Confusion, dizziness, and disorientation 
• Tremors and excessive sweating 
• Loss of consciousness or coma 
• Seizures 
• Brain damage from prolonged low blood sugar 
• Death 

From Falsely Low Readings (Leading to Missed Insulin Doses): 

• Severe hyperglycemia (blood sugar rises too high) 
• Diabetic ketoacidosis (DKA) 
• Excessive thirst and frequent urination 
• Fruity-smelling breath 
• Rapid heartbeat and hyperventilation 
• Nausea and vomiting 
• Confusion and altered mental state 
• Death
