Abbott Libre 2 and 3 Discontinued: Latest Transition

Abbott Libre 2 and 3 discontinued in 2025, yes, as of September 30, 2025, Freestyle Libre 2 and Libre 3 sensors have been officially discontinued in the USA. This transition leaves current users wondering about the next steps in glucose monitoring. In their place, Abbott has launched the Freestyle Libre 2 Plus sensors and Freestyle Libre 3 Plus sensors, which offer enhanced features and improved technology.
If you’re a current user or considering a transition, here we’ve covered almost everything you need to know about the new Libre 2 Plus and 3 Plus sensors.

Impact of Libre Sensors Phasing Out

The discontinuation of the Libre 2 and Libre 3 sensors has undoubtedly affected many individuals who rely on these CGMs for diabetes management. However, Abbott’s introduction of the Libre 2 Plus and Libre 3 Plus is designed to offer a smooth transition with improved features.

• Phased Out: The Libre 2 and Libre 3 sensors are no longer going to be available after September 30, 2025. This means you are now required to transition to the newer Plus models.
• Improved Technology: The Libre 2 Plus and Libre 3 Plus sensors come with longer battery life (compared to their older models), improved compatibility with Automated Insulin Delivery (AID) systems, and finally, the mean absolute relative difference (MARD) of less than 10.
• Prescription & Insurance: Transitioning will likely require a new prescription and an updated insurance plan to accommodate the Libre Plus models.

Did you know?

Not storing your sensor kit between the recommended temperature of 36°F to 82°F may alter your glucose results, and the same applies to incorrect application or loose sensors.

For Those Unsure About Continuous Glucose Monitors (CGMs)

Continuous Glucose Monitors (CGMs) are changing how diabetes is managed. Unlike traditional blood glucose meters, which require you to prick your finger every time you check your blood sugar, CGMs, once inserted with the help of a micro pin (typically on the back of your upper arm or abdomen), continuously track glucose levels throughout the day and night.

This 24/7 glucose data helps people make more informed decisions about insulin usage, diet, and exercise. And Freestyle Libre sensors have been at the lead of this transformation, with some even being the favorite of many, like the Freestyle Libre 3 sensors, which have now been discontinued.

Transitioning to the New Libre Plus Sensors

If you’re currently using the Libre 2 or Libre 3 sensors, here’s what you need to know about the transition:
