If you are searching for how to get a libre 3 plus sensor replacement right now, there is something more urgent to check first. Abbott issued an FDA Class I recall, the most serious category, covering certain FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors due to a manufacturing defect that can display falsely low glucose readings. This is separate from an everyday sensor falling off or throwing an error, and it changes the first step you should take.
What to Use While You Wait
Whether your replacement is recall-related or a routine failure, Abbott and the FDA both give the same instruction in the meantime, use a blood sugar meter or the built in meter function on a FreeStyle Libre 3 Reader to make any treatment decision until a working sensor is back on your arm. This is exactly why keeping a traditional glucose monitor on hand, even as a backup to daily continuous glucose monitoring, remains genuinely important rather than an outdated habit.
A Second Recall Worth Knowing About
This is not the first correction of its kind. In July 2024, Abbott recalled a separate batch of Libre 3 sensors for the opposite problem, falsely high readings, which the FDA also classified as Class I. Two Class I recalls within roughly 18 months is worth knowing if you are deciding between the freestyle libre 3 plus and a dexcom g6 receiver setup, since it shows the kind of manufacturing issue that can affect any cgm device, not a reason to avoid CGMs altogether.
Buying and Replacing Going Forward
If you buy freestyle libre 3 plus online, keep your purchase receipt and lot number regardless of which pharmacy or supplier you use, since that information speeds up both a standard freestyle libre 3 sensor replacement and any future recall check. Freestyle libre insurance coverage is unaffected by this correction, replacement sensors are provided free directly by Abbott and do not run through your pharmacy benefit at all.
