FreeStyle Libre 2 Sensors Discontinuation

FreeStyle Libre 2 (FSL2) sensors will be discontinued in August 2025 with stocks previously predicted to be running low by June 2025. The SY ICB Medicines Optimisation Team will now be supporting practices to switch any remaining patients on FSL2 to FSL2+ with the aim to ensure that no patients remain on FSL2 beyond August 2025.

FSL2+ sensors work with the existing FreeStyle LibreLink app and the FSL2 reader but have the following additional/improved features:

• Extended sensor wear: Easy to use and comfortable to wear for up to 15 days versus 14 days for FSL2.
• Better performance: Outstanding 15-day accuracy in the low end, where it matters most.
• Partnerships with insulin pumps: Designed to work the Omnipod® 5 Automated Insulin Delivery System,offering personalised automated insulin delivery and care for people living with type 1 diabetes, based on their glucose sensor readings.

When prescribing FSL2+, the directions should clearly state that the sensor must be replaced every 15 days and patients should adhere to the 15-day wear period, rather than 14-days with FSL2. Please could you support to emphasise this duration to patients.

Please refer to the Abbott website for more information and references. (Freestyle Libre 2 Plus Sensor)

Patients who do experience issues with their sensor being faulty or falling off before the 15-day period ends, should be directed to Abbott’s online UK Sensor Support Form (Sensor Support Form | United Kingdom | FreeStyle Libre | Abbott) where this can be reported and a replacement requested. Alternatively, for patients who would rather speak with a representative, they can contact Abbott general enquiries on 0800 170 1177 (Monday to Friday 8am – 8pm and Saturday 9am – 5pm (excluding bank holidays).

Please note that Abbott will request the sensor serial number on the packaging, so please advise patients to not dispose of this until the 15-day wear period of the sensor has expired.
