Dexcom Setup Step 1: Download the apps

If you use the Freestyle Libre CGM, navigate to Setting Up Your Levels with FreeStyle Libre CGM.


Before you start: 

You will want to set aside at least 30-45 minutes to complete the Dexcom setup process.

To ensure your set-up process is as successful and easy as possible, we recommend the following:

  • Use a desktop computer to follow these instructions. You’ll be actively using your mobile device during the set-up process, and it’s an easier and better experience if you have instructions open on a different device to follow along
  • Pick the right time. We recommend applying your sensor first thing in the morning when your glucose is the most stable and to avoid calibration issues while you’re sleeping. We also recommend applying your sensor on an empty stomach (i.e. 2 hours before or after eating). 
  • If you're replacing this CGM with a new CGM, do not apply the new sensor within 20 minutes of ending your previous CGM. If this is your first time applying a Dexcom CGM, please disregard this bullet point.

What's in my Levels Kit?

  • 6 Performance Covers to keep your sensor and transmitter protected.
  • Three 10-day Continuous Glucose Monitors (CGMs) in one box.
  • One transmitter - This transmits the data from the sensor to your device via bluetooth and is good for 90 days. IMPORTANT: Do not throw away your transmitter. You will reuse your transmitter with new CGMs until its lifespan of 90 days is complete. We’ll make sure to send you a new transmitter in further subscription kits before your current one expires. 
  • Welcome card with information on how to set up your device.
  • Alcohol swabs.
