Clean and Dry Before Using
Before opening the sensor package, wash your hands with soap and water, then dry. If
your hands are dirty while inserting the sensor, you may contaminate the insertion site
and get an infection.
Before sensor insertion, clean the skin with alcohol wipes to prevent infections. Don't
insert the sensor until the cleaned insertion site is dry, and free from any lotions or
perfumes.
If your insertion site is not clean and completely dry, you run the risk of infection or the
sensor pod not sticking and falling off.
Sensor Placement
Change the site where you place the sensor with each new insertion. Using the same
site too often might not allow the skin to heal, causing scarring or skin irritation.
Sensor placement is important. Make sure the area you place your sensor won't:
• Be bumped, pushed, or squeezed
• Have scars, tattoos, or irritation
Insertion in these areas might affect sensor performance, resulting in you missing a
severe low or high glucose event.
Avoid injecting insulin or placing an insulin pump infusion set within three inches of the
sensor. The insulin might affect sensor performance, resulting in you missing a severe
low or high glucose event.
