SIMPLE STEPS TO START USING YOUR FREESTYLE LIBRE SENSOR

Are you ready to get the full picture of your changing glucose levels throughout the day and night^φ with your new FreeStyle Libre system? If so, we want to help you get the most out of it.

Please refer to the FreeStyle Libre system User Manual for complete instructions.

CHOOSING THE SITE

Your sensor is the key to getting your complete glucose picture so don't forget to choose the site correctly and apply your sensor with care:

Select an area of skin on the back of your upper arm that generally stays flat during normal daily activities (no bending or folding).

Avoid areas with moles, scarring or tattoos.

Choose a site that is at least 2.5cm (1 inch) away from an insulin injection site.

To prevent discomfort or skin irritation, you should select a different site other than the one most recently used.

APPLYING THE SENSOR

Now that you have prepared the site, you're ready to apply your sensor. The Sensor Pack and Sensor Applicator are packaged as a set (separately from the Reader).

Open the Sensor Pack by peeling off the lid completely. Unscrew the cap from the sensor applicator and set the cap aside.

Line up the dark mark on the Sensor Applicator with the dark mark on the Sensor Pack. On a hard surface, press firmly down on the sensor applicator until it comes to a stop.

Place the Sensor Applicator over the prepared site and push down firmly to apply the sensor to your body.

Gently pull the Sensor Applicator away from your body. The Sensor should now be attached to your skin.

Make sure the Sensor is secure after application. Put the cap back on the Sensor Applicator. Discard the used Sensor Pack and Sensor Applicator according to local regulations.
