The new system is available on prescription for people living with type 1 and type 2 diabetes.

The first real time-continuous glucose monitor (rt-CGM), with no scanning and no finger pricks, is now available to people with diabetes from the pharmacy. 

From this week the Dexcom ONE system is available on prescription in the UK for people with type 1 and type 2 diabetes using insulin.

A starter pack can be collected at GP surgeries and hospitals by patients in the UK to receive more information on the product and usage, a sensor and transmitter. Then, once prescribed, they can go to the pharmacy for their repeat prescription.  

Dexcom ONE is a smart, easy to use wearable sensor and transmitter.

The device will enable people with diabetes to:

  • Eliminate painful finger pricks: The rt-CGM device will continuously monitor glucose levels in real-time and sending values wirelessly to a compatible smart device via the system mobile app or receiver, providing a complete picture of glucose levels and trends.  
  • Have exceptional accuracy: The user-friendly app and receiver display trend arrows to show the speed and direction that glucose levels are heading, helping make in-the-moment treatment decisions easier.
  • Be offered a personalised experience: A range of personalised alerts warn of potentially dangerous high or low glucose events so action can be taken, with a delayed first alert feature to avoid alarm fatigue. 
  • Access to Dexcom Clarity: The data management software package provides remote data sharing with healthcare professionals, as well as trends and patterns at all times.


This development follows the new guidelines from the National Institute for Care and Excellence (NICE) which recommended adults with type 1 diabetes should be offered a choice of glucose sensor, children should be offered rt-CGM and people with type 2 diabetes using insulin can be considered for rt-CGM as an alternative to their current sensor. 

Professor Partha Kar, National NHS Specialty Adviser for Diabetes, said: “The next step in the evolution of type 1 diabetes technology continues to unfold and at NHS England, we are thrilled to be part of the solution. With Dexcom ONE on prescription, more people will have access to potentially life changing CGM technology, leading to better health outcomes and more choice for people with diabetes.”

Karen Baxter, Vice President, UK and Ireland, Benelux, France and Spain at Dexcom: “The addition of Dexcom ONE to the NHS England, Wales, Scotland and Northern Ireland drug tariff is enormous progress towards improving choice of diabetes tech, providing an alternative to burdensome finger pricks and scanning. We are incredibly proud of the diabetes community and are working hard to make it easier for them to access the best technology possible to manage their diabetes. As a next step, we will be working closely with healthcare professionals to ensure the diabetes community can benefit as quickly as possible from reimbursement and wider availability of Dexcom CGM.” 

Dexcom ONE is part of a range of CGM systems offered by Dexcom for people with diabetes in the UK that also includes the Dexcom G6 and the upcoming Dexcom G7. With the new portfolio of products, Dexcom meets the entire criteria set out by NICE.
