Optional Alarms
with the FreeStyle Libre 2 System

Easy to set up and use
Optional glucose alarms are easy to turn on, easy to customise low and high glucose alarm ranges and easy to adjust sound and vibration.5
Increased device use
New FreeStyle Libre 2 users value the ability to control alarms — patients who switched from other CGMs saw a 44% increase in device use "all or almost all of the time".6,7 Other CGM users are 2x more likely to turn off their device* due to excessive alarms.6,7
How It works
Alarm
When your patient receives a glucose alarm, they can open the FreeStyle LibreLink app or tap the Dismiss button to dismiss the alarm.
Act
They can then use their glucose reading, trend arrow, and 8-hour history to take appropriate action as their Healthcare Professional advice.
It even works when they're sleeping or when their smartphone is in Do Not Disturb mode.¤
iPhone users who use Focus Modes will need to make sure Time Sensitive Notifications are turned ON for each focus mode.
Your patient will need to decide which device they want to receive their alarms on. This is an important first step as they can only receive alarms on the device they start their FreeStyle Libre 2 sensor with.

How to activate alarm notifcations
To receive optional glucose alarms on their smartphone, your patient needs to make sure they have notifications enabled for the app. If they didn't enable all notifications and permissions during app set up, how they do it now depends on their phone's operating system.

Check to make sure that you have the correct settings and permissions enabled on your phone to receive alarms.
