Glucose Monitoring Systems (CGM) Available in Ireland
This page was last updated on 18 June 2026.
Continuous Glucose Monitoring (CGM) systems, sometimes referred to as “patches, " are devices that monitor glucose levels 24 hours a day. These devices take a glucose value every 5 minutes or less, giving the wearer an average blood glucose level and where it’s heading (trend arrow) for that hour.

Can I get any CGM?
In July 2024, the HSE’s Medicines Management Programme created a List of Preferred CGM sensors. There are two lists of Preferred CGMs: List A and List B.
List A
The MMP recommends that a person with diabetes who is not using an insulin pump is offered a CGM from List A when:
They are using a CGM for the first time,
Or when the continuation of CGM is being reviewed as part of their clinic appointment
List B
This list of CGMs is mainly comprised of those used as part of closed-loop insulin pump systems, with the exception of GlucoRx Aidex.
If you are an existing user of a CGM from List B and do not use an insulin pump, you will be asked to switch to a CGM from List A unless there is clinical justification for continued use of a CGM sensor from List B.
HSE Preferred CGM List A
HSE Preferred CGM List B
Maximum Number of Sensors Allowed Per Person
Each person is allowed a set number of CGMs per year depending on the CGM they use. Failed or faulty sensors need to be reported to the company providing them (see image below from HSE Pharmacy Circular 00924 RE Identification of preferred continuous glucose monitoring sensors).

What are the differences between the sensors?
An easy-to-understand CGM Comparison Chart is available from the Diabetes Specialist Nurse Forum UK website, which was updated in 2026. This resource allows you to compare CGM features side by side.

Everyone's diabetes is different, and there is no single "best" CGM for everyone.
Choosing a CGM can feel overwhelming, especially with several systems now available in Ireland.
