How do I remove and replace my CGM?

Your CGM sensor is designed to stay on for up to 14 days. The Libre app will notify you when it’s time to remove it.

To remove/replace your CGM, please follow these steps:

  1. Remove Sensor: Pull up the adhesive edge that keeps it attached and slowly peel from your skin in a single motion.
  2. Replace Sensor: Apply the new CGM sensor to a different spot on the back of your arm to avoid skin irritation. Switching arms with each new sensor can help.
  3. Sensor Disposal: Dispose of your sensor following all applicable local regulations related to the disposal of electronic equipment, batteries, sharps, and materials potentially exposed to body fluids.
