I got a Critical Low Alarm from Dexcom. What should I do?
Dexcom has a feature to warn you when your glucose falls below 55 mg/dL. This alarm goes off even if your phone is set to Silent, and there’s no way to disable it from the Dexcom app. While the majority of users don’t experience this, some people experience nighttime pressure-induced lows which can cause the alarm to sound.
You have two options for halting these alarms. Note that it is only appropriate to halt these alarms if you are using the CGM for general-wellness purposes through the Levels program. Anyone using the Dexcom for any medical purpose must not attempt to disable the alarms.
1. Turn off alarms in your phone’s Notification Settings.
Navigate to iPhone Settings >> In top search bar, type Dexcom G6 or Dexcom G7 and select >> Select Notifications >>Toggle off both Critical Alerts and Time Sensitive Notifications
Navigate to the app drawer >> long press on the Dexcom G6 or G7 app >> select App Info. On the following screen, you have override control for any notifications that come from the app.
