Top FAQs

  • The Dexcom G6 app has to be downloaded and is different from the Dexcom G5 Mobile app. (Please note: The G6 system will not work with the G5 Mobile app.) It is available for free from the Apple App or Google Play stores. The app is named “Dexcom G6”.

  • We are always adding (and in this case removing) new phones to/from our compatibility list. Please check the website for the most up-to-date list of compatible phones - www.dexcom.com/compatibility.

    LBL016100 Rev002
  • A variety of iOS and Android smart devices are compatible with G6. Compatibility is listed here: www.dexcom.com/compatibility

    LBL016100 Rev002
  • iOS and Android platforms are compatible for Followers. To view the latest supported devices, visit www.dexcom.com/compatibility

    LBL016100 Rev002
  • Yes, the Follow App works the same way as it did with the Dexcom G5 Mobile. 

    New followers - Download the Dexcom Follow app from the Apple App Store or Google Play Store. 

    Existing followers - The Dexcom Follow app is the same so there is no need to download it again if it’s already installed. However, Followers must be re-invited by the Sharer in the G6 app to start following again. 

     

    LBL016100 Rev002
  • Yes, the Dexcom G6 app will be available for free download in the Google Play and Apple App Stores. The Dexcom G5 Mobile App will not work with a G6 System and vice versa. 

    LBL016100 Rev002
  • The option to enter calibrations was included to allow a user to manually calibrate the system in case the start-up calibration code is lost. The system is designed to work properly without calibrations.  

    LBL016100 Rev002
  • Without your sensor code, you’ll need to calibrate twice after your 2-hour sensor warmup is complete, a third time 12 hours later, a fourth time 12 hours after that, and then once every 24 hours. 

    LBL016100 Rev002
  • Yes, you’ll need to put in the sensor code from the sensor each time you start a new one. The sensor code is found on the bottom of the applicator on the adhesive strip. 

    LBL016100 Rev002
  • When you start a new sensor, you must enter a code into your display device to use the G6 without fingerstick calibrations. Each sensor has its own code printed on the back of the adhesive patch. Do not use a code from a different sensor or make up a code. If you do not enter the correct code, your sensor will not work as well and could be inaccurate. If you have lost the sensor code, you may calibrate the G6 using fingersticks.  

    LBL016100 Rev002
  • Dexcom Share is a feature within the G6 app that allows for remote monitoring.   One person, (the Sharer) may transfer their CGM information to another person (the Follower). To setup Share simply press the Share icon in the app and follow the onscreen instructions.

    *Requires separate Follow App and internet connectivity.  

    LBL016273 Rev002
  • Just like G5 Mobile, sensor insertion sites are on the belly (age 2 years and older) or the upper buttocks (ages 2-17 years). 

    LBL016100 Rev002

  • The “Urgent Low Soon” alert is a new alert that can warn users in advance (within 20 minutes) of a severe hypoglycemic event (55 mg/dL) — allowing them time to take appropriate action before an event happens. 

    LBL016100 Rev002
  • No. The new Dexcom G6 CGM system is designed to eliminate the need for fingerstick calibrations* and can be used for treatment decisions for 10 days without restart.  

    *If your glucose alerts and readings from the G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.

     

    LBL016100 Rev002
  • The Dexcom G6 sensor can be worn up to 10 days. 

    LBL016100 Rev002
  • A G6 transmitter lasts for three months (same as G5 Mobile). 

    LBL016273 Rev002
  • A new Dexcom patient will receive the Dexcom G6 system – a receiver, transmitter and sensors. If you’re an existing Dexcom patient who has the Dexcom G5 touchscreen receiver, you can upgrade the receiver with the new G6 software (visit store.dexcom.com/update-tool) and only purchase the sensors and transmitter. If you decide to use a compatible smart device*, you will need to download the new Dexcom G6 app.

  • The Dexcom G6 is the latest generation of CGM available from Dexcom. New features include factory calibration, a 10-day sensor wear period, a one-touch auto-applicator, a new “Urgent Low Soon” Alert, acetaminophen blocking* and a discreet, low-profile wearable transmitter.

    *G6 readings can be used to make diabetes treatment decisions when taking up to a maximum acetaminophen dose of 1,000mg every 6 hours. Taking a higher dose may affect the G6 readings.

    LBL016100 Rev002
  • The Dexcom G6 is Dexcom’s latest generation continuous glucose monitoring (CGM) system. Unlike previous generations, this CGM system is factory-calibrated—so no fingersticks are required.* The Dexcom G6 is comprised of a sensor, transmitter and display device (receiver and/or compatible smart device)**. The system features a redesigned, one-touch auto-applicator and sleek, discreet transmitter. The Dexcom G6 sends glucose readings to a smart device or the Dexcom receiver every 5 minutes. The Dexcom G6 is indicated for patients ages 2 and older.

    *If your glucose alerts and readings from the G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.

  • We recommend checking the Dexcom compatibility chart before installing a new iOS or Android OS version on your smart device. Dexcom tests all its apps on new OS versions after the OS is released. It may take several days or more to complete testing and, if necessary, update the Dexcom app to be fully compatible with a new OS version.
