Set them on their journey to better diabetes management

Resources and guidance to help pharmacists and pharmacy assistants empower customers with Dexcom ONE and Dexcom ONE+ Continuous Glucose Monitoring (CGM) technology. Now available on prescription for people with diabetes on insulin and those meeting certain criteria.1-3 

Standard of care is changing

NICE (National Institute for Health and Care Excellence) now recommends that people with type 1 diabetes are offered a choice of glucose sensor, including CGM.1 Children and young people with type 1 diabetes should be offered CGM.2 For people with type 2 diabetes the recommendation is that CGM can be considered as an alternative to intermittent scanning (isCGM).

The Dexcom ONE and Dexcom ONE+ sensors last up to 10 days and can be ordered by prescription on the NHS, if the customer is eligible as per local criteria. Dexcom ONE+ features an all-in-one sensor and transmitter that is smaller, faster, and even easier to use.8 If patients are using Dexcom ONE, the transmitter is separate and re-useable and has a 3-month battery life.
