Here are step-by-step instructions for how to apply your sensor.

These instructions only apply if you have a Libre 14-day sensor. If you have a Libre 3 sensor, please reach out to us via our chat feature and we can investigate this further for you.

Step 1

Pick a spot on the fleshy part of the back of your upper arm. It’s best to apply your sensor to your non-dominant arm.

Step 2

Clean the spot with the provided alcohol wipe and wait 30 seconds for it to dry.

Step 3

Peel the foil lid off the sensor pack.

Step 4

Unscrew the cap from the sensor applicator.

Step 5

Line up the dark marks on the sensor applicator with those on the sensor pack.

Step 6

On a hard surface, press down firmly in one motion on the sensor applicator until you hear a ‘click’ and it comes to a stop. Then carefully lift the sensor applicator out of the sensor pack.

Your applicator now contains the sensor and is ready to apply. Please take care as the sensor applicator now contains a filament.

Step 7

Place the sensor applicator over the chosen site on the back of your upper arm. Firmly push the applicator against the back of your arm until you hear a click sound. Don't worry, it's not painful. Then pull the applicator away gently and make sure the sensor is secure.

Please dispose of the sensor applicator and pack in the trash.

Step 8

Place the adhesive patch on top of your blood sugar sensor.

This patch is so sticky that once it’s on, you won’t be able to get it off without removing the blood sugar sensor along with it. So if possible, get someone to help you with this step to make sure it’s placed on properly.
