Dexcom G7 continuous glucose monitor (CGM) Important Information

 From the 1st of March 2025 the Dexcom G7 CGM will be available via NDSS. There are a couple of things to be aware of if you want to upgrade to the Dexcom G7:

• It is not yet compatible with the Ypso insulin pump therefore Ypso users will need to continue to use the G6 until advised.
• The Tandem T-slim does provide compatibility with the Dexcom G7 and you can find more information here. 
  - Ensure you check your CGM menu for a G7 selection item on your Tandem t:slim pump. If you can't see this option, you need a pump upgrade (if out of warranty) or a software update (if in warranty), before changing to the Dexcom G7. AMSL will send out the information for a software update or please contact AMSL if you have not received these instructions. 
• Ensure the Dexcom G6 app or device is removed from you mobile phone and pump before starting G7.  
  
• Log into the Dexcom G7 app using the same log in details as the Dexcom G6, there is no need to create new account.
  
• Check that your mobile phone is compatible with the G7 before upgrading.

To upgrade to the Dexcom G7, you will need to contact us at diabetes@rch.org.au or speak to us in diabetes clinic and request an update to your CGM information through NDSS. When you get email confirmation that this change has been processed, you will then be able to go to your chemist and collect your G7 as you would with your G6–  we suggest that you advise your chemist to order in the G7 before you email us and check you have enough G6 supplies before requesting us to change to the G7 in case of any delays. 

See instructions to using the Dexcom G7 and how to insert the Dexcom G7.

When using the G7 for the first time a key difference is the all in one insertion push the applicator down onto your skin and then push the button to insert your sensor, remove the applicator and then press down on the inserted transmitter for 10 seconds.

You can link to Clarity and the clinic's Clarity through the G7 app with the code 0393456661.
