Abbott FreeStyle Libre 2 User Manual

Replacing Your Sensor
Your Sensor automatically stops working after the wear duration and
must be replaced. You should also replace your Sensor if you notice any
irritation or discomfort at the application site or if your device reports a
problem with the Sensor currently in use. Taking action early can keep
small problems from turning into larger ones.
CAUTION: If the Sensor is becoming loose or if the Sensor tip is
coming out of your skin, you may get no readings or unreliable
readings, which may not match how you feel. Check to make
sure your Sensor has not come loose. If it has come loose,
remove it, apply a new one, and contact Customer Service.
Customer Service is available at 1-855-632-8658 7 Days a Week
from 8AM to 8PM Eastern Standard Time.
