To help the T1D community stay informed, we are sharing Abbott’s guidance in full below:

  • People using FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors should visit FreeStyleCheck.com or call Abbott Customer Service on 0800 170 11 77 to confirm if their sensors are impacted. If their sensor is impacted, they will be instructed to provide their contact information so a replacement product can be sent to them at no cost.
  • If someone is currently wearing or has a FreeStyle Libre 3 or FreeStyle Libre 3 Plus sensor that has been confirmed as affected on FreeStyleCheck.com or by Abbott Customer Service, they should immediately discontinue use and dispose of the affected sensors.
  • People can continue to use FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors that are not impacted.
  • Individuals should use a blood glucose meter such as the built-in meter in the FreeStyle Libre 3 Reader to make treatment decisions when sensor readings don’t match symptoms or expectations.
