Frequently Asked Questions

If patients experience any difficulty removing the sensor from their skin, these products and techniques may help:  

General Removal Techniques 

• Loosen edge of adhesive with fingernail and use products listed below if necessary.^1,2  

• While removing tapes, use fingers of opposite hand to push skin down and away from adhesive. Continue to move fingers on skin towards adhesive as it is removed.²  

• ‘‘Fold back’’ technique: Remove adhesive slowly, at low angle, folding back on itself. ²  

• ‘‘Stretch and relax’’ technique: Films that stretch (e.g., IV3000 or Tegaderm) may be stretched horizontally away from the centre (opposite of the fold back technique) while walking fingers under the dressing to continue stretching it. ²  

• Use adhesive removal wipes to rub the skin under the tape towards the adhesive as it is removed. This helps loosen adhesive from skin and may help reduce pain with removal.¹

Yes, Dexcom G6 is indicated for children as young as 2 years old. 

Dexcom Sensors are manufactured with a special adhesive to help them stick to patients’ skin after insertion. Adhesive supplements may also be used.  

• Liquid adhesive agents can be used with the sensor adhesive patch.^1,3 Suggestions for patients when using liquid adhesive agents are to:  

1. Create an empty oval on the skin with the liquid adhesive product.  

2. Let skin adhesive dry.  

3. Insert sensor on clean skin in centre of oval.  

• Additional adhesive patches or tape can be applied over the sensor adhesive patch. ^1,2 Suggestions for patients when using adhesive patches or tapes are to:  

• Cut a hole in the adhesive patch or tape to fit around transmitter.  

• Cut the adhesive patch or tape into strips to use ‘‘picture frame’’ technique around sensor adhesive patch.^1,4

Until recently the only way to know your glucose levels was to prick your finger. Whilst finger pricking is able to measure your current glucose level at the time, it can’t predict where your glucose levels are heading or how quickly. So, you end up having to finger prick again and again to try and build up a picture. Many people grow frustrated at still being unable to predict hypoglycaemia and hyperglycaemia, or keep their glucose in range.

Now, with the increase in use of real-time CGM systems, this has all changed.

CGM systems, such as Dexcom G6 and G7, measure glucose levels every 5 minutes and send the readings via a small transmitter to a touch-screen receiver or smartphone†. This shows you how your glucose levels are changing, allows you to predict what they’ll do next and alerts you if levels are heading too high or too low – all without finger pricks* or scanning.

You can even share your Dexcom G6 and G7 glucose data§ with friends and loved ones via the ‘Share’ feature in the Dexcom G6 app so that they can stay connected as your circle of support.

For mobile users, CLARITY displays glucose data from a Dexcom CGM system 3 hours after the data is captured. This means that the most recent data you view in CLARITY is at least 3 hours old.

For Dexcom Receiver users, the data is as current as the last upload. 

It is possible to use both a smartphone and a receiver to provide CGM data. The smartphone system streams data to the CLARITY server, where that data is made available for reports after three hours. The Dexcom receiver requires connection to a computer to upload the data periodically. If the patient uses a smart device part of the time and a receiver part of the time, then CLARITY needs data from both to provide accurate statistics. 

The Dexcom Clarity app highlights glucose patterns, trends and statistics. You can even get weekly notifications with the Dexcom Clarity reports app. This data can be shared with the diabetes healthcare team to monitor changes remotely.

CGM Systems are included on the long-term illness scheme and are available to people with type 1 diabetes who meet the clinical requirements. Full details on the requirements for adults can be found here.  

There are no set criteria for CGM use in children with type 1 diabetes but most consultants use the National Institute for Health and Care Excellence (NICE) guidelines in the UK. 

If you would like to find out more about Dexcom G6, please reach out to your local Dexcom Representative who will be able to assist you.

Yes, a funding application form must be completed by a hospital consultant through HSE under approved criteria.

If approved, funding is given for a 12-month supply of Dexcom G6 CGM. The first prescription is issued by the hospital diabetes team to obtain a supply of G6 sensors from the pharmacy. 

With real-time CGM your current glucose levels and trends are sent automatically to a compatible smart device† up to every 5 minutes.

With a Flash glucose monitor, it’s only when you wave (scan) the device over the sensor that you get the current glucose reading. This is also known as intermittent scanning (is-CGM). Unlike real-time CGM, Flash glucose monitors do not transmit so it will not alert you to low or high glucose levels until you ‘flash’ the sensor.

Dexcom CGM and Flash are subject to different eligibility criteria. You can find more information in the HSE guidelines here.

There are eligibility guidelines for CGM available on the HSE (Health Service Executive) website. But, no, Dexcom G6 is not limited to patients using insulin pumps.   

Further details can be found in the Department of Health type 1 diabetes mellitus guidelines.  

Yes, patients who are not eligible under the HSE criteria can self-fund a Dexcom G6 CGM System. Please advise your patient to call the Dexcom sales team (1800 827 602) for further information.

Dexcom G6 is suitable for anyone with diabetes over the age of 2 years, including pregnant patients. It can be worn by patients who use a pump and by those on multiple daily injections.  

A long-term health economic analysis was performed to establish the cost-effectiveness for funding of the Dexcom G6 versus fingerstick testing. It examined UK-based type 1 diabetes patients with elevated HbA1c.  Elevated levels can increase the risk of developing diabetes-related complications.  

The Dexcom G6 falls well below the cost-effectiveness threshold set by NICE in order to be recommended for NHS funding.
