Glucose Monitoring Systems (CGM) Available in Ireland

* This page was last updated on 10 August 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 August 2026, the HSE’s Medicines Management Programme (MMP) updated it’s List of Preferred CGM sensors (HSE MMP, 2026). More information about the MMPs evaluation process can be found on their webpage here.

There are two lists of Preferred CGMs: List A and List B.

List A (for stand-alone use)

The MMP recommends that a person with diabetes 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.

  • The List A -Preferred CGM sensors are: Freestyle Libre 2 Plus, Freestyle Libre 2 (for existing users only), Dexcom ONE+, Accu-Chek SmartGuide AND Freestyle Libre 3 Plus (only if in use with the Mylife Ypsopump).

List B Non-preferred CGM sensors UNLESS CLINICALLY JUSTIFIED

CGMs on List B are only recommended if there is clinical justification for continued use, for example if the person with diabetes is using an insulin pump that does not support the CGMs from List A. These CGMs are: Dexcom G6, Dexcom G7, GlucoRx Aidex, Minimed Medtronic Guardian Sensor 3, Minimed Medtronic Guardian Sensor 4 and Minimed Medtronic Simplera Sync Sensor.

The updated posters for preferred CGM sensors can be found below.

Maximum Number of Sensors Allowed Per Person

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.

The information on this page is intended to help you understand the options available and start informed conversations with your diabetes healthcare team.
