Due to a manufacturing process issue that may cause carbon build up in the sensor that may result in incorrect low glucose results

Users of the FreeStyle Libre 3 sensors reported situations where they were receiving erroneously high glucose results. The inaccurate higher glucose values may lead to users calculating higher insulin bolus correctional doses based on inaccurate CGM glucose data. The inaccurate higher glucose values may also contribute to missed or delayed recognition of hypoglycemia, when the sensor incorrectly reports normal or even high glucose values when the actual glucose is trending low or is low. If the hypoglycemia missed by the device occurs acutely, a user may not be able to confirm the actual glucose with a self-monitored blood glucose (BG) and/or administer prompt intervention to raise glucose levels. The over-delivery of insulin and/or the missed or delayed detection of impending or overt hypoglycemia in the worst-case scenario may lead to severe hypoglycemia/hypoglycemic crisis with significant adverse health consequences. Such consequences include central nervous system dysfunction, loss of consciousness, seizure activity and may lead to coma, permanent neurological damage, and death.

If using affected glucose monitoring app on Android 13 Operating System, extended periods of signal loss may be experienced, due to app not connected, which could impact ability to receive glucose reading/alarms, which could lead to undetected low or high glucose, which could result in delayed treatment: not taking insulin (for high glucose), or not taking glucose (for low glucose) when required.

If blood glucose monitoring system users attempt to start a new sensor, when the old sensor wasn't used for the full 14-day wear time, then the reader may display "Incompatible Sensor" message. If users don't have the previous sensor, or FreeStyle Libre 2 app, or the sensor's full wear time hasn't ended, users may be unable to start a new sensor, which could result in no or delayed glucose results

Lithium-ion batteries in glucose monitoring system readers may swell, overheat, or pose fire hazard. Only use the charging cable/power adapter included with readers. Do not use reader if it is damaged, cracked, swelling, too hot to hold, it will no longer hold charge, or it fails Reader Test. Do not use other chargers. User Manual update includes instructions on reader safe storage, charging, use.
