DEXCOM ONE PLUS

I have just changed to one plus from one. First sensor failed immediately before warm up was complete. I have had endless failed sensors with dexcom one and yes dexcom replace them but it's still painful when you are travelling and you think you've taken enough spares but then you haven't.
The pharmacist in local Boots today said to me you've you got the cheap tech! I don't even mind it being cheap if it does the job, bit it's just the feeling that now you always get cheapest rather than best on the NHS (and I work in the NHS).
A specialist nurse from Dexcom who rang me re all the failed sensors and to whom I'm speaking again on Monday, told me I should push for G7 and I have tried but in my area (Surrey) that can only be prescribed via hospital and requires an MDT and I just don't seem to be able to get them to approve. Does anyone if there are specific criteria for getting G7 e.g. must be using a pump, or age criteria, younger type 1s seem to get G7. I don't begrudge that at all, but I just wonder why it is as it is. I use pens Lantus and Trurapi.
I struggle with left arm, it always hurts no matter how careful I am with insertion. Right arm no problem. I can't bring myself to wear it on my abdomen although I'm ok injecting there.
Any insights would be appreciated.
 
Mine works better on my abdomen than it ever did on my arm. Also no compression lows (unless you sleep on your front) and not easily dislodged. In about a years subscription I have had 2 replaced. I think Boots were being a bit unfair as, yes it’s cheaper, but it doesn’t have the bells and whistles that G7 has, so as a continuous monitor without a pump connection, then it does the job.
 
Sorry to hear you’ve been having a lot of sensor fails with Dexcom One, and now Dex One+ @london5 - that does seem to be an unusually high failure rate :(

Have you tried Libre 2+?

Some people’s bodies seem to get on better with one sensor tech over another. Might be worth getting a free trial from Abbott (I think you can just request a Libre 2+ on their website), and considering a switch if you get on well with it?
 
Also, @london5, switching between Dexcom One+ and Libre 2+ is cost neutral to the NHS, so there ought to be zero resistance by your GP Surgery to a request for a switch, in order that you can try the Libre alternative for several fortnights before confirming your compatibility to Libre. The only possible caveat is if your Integrated Care Board (ICB) have been offered a specific "deal" by one of the manufacturers to benefit from possible financial savings. In principle this shouldn't become a hindrance, since the NICE Guidance Note NG17, which is the overall authority for T1 and CGMs, provides for allowing switching because of incompatibility.

I was the other way round. In 2022 I switched from Libre to Dexcom One because of my recognised incompatibility to Libre 2. I was then upgraded to Dex G7 by my Hospital, after I self-funded G7 for 9 months and demonstrated that was best for me. The big difference between my GP prescribed and Hospital provided sensors is that Hospital funded comes from a rolling contract between the Trust and Dexcom (or Abbott for Libre) with an automatic resupply every 3 months, ie 9 x 10 day sensors; no script renewal submissions and a healthy reserve of sensors at home. Whereas GP prescribed generally come 2 or 3 at a time and need script renewal requests monthly.
 
I'm likely to be going the same way, as it would appear that Abbott might have started adding something to their adhesive that I am apparently allergic to. I suspect it is rosin, as I have previously exhibited a reaction to Elastoplast.

The reaction shows as intermittent itching around the area of the sensor and a fairly fiery red ring when I've removed it. This lasts just a day or so. It's not unbearable, but if the alternative is better, a switch will be on the cards.

As I'd not experienced any issues with the Libre 2 and as I'd also used 4-5 libre 2 plus without problems, I am guessing that the number of complaints about sensors falling off might have prompted a change in adhesive ingredients. At least some of these sensors were possibly falling off mainly due to the unusually hot weather we've been having, in the UK, causing more sweating and compromised adhesion, but that's also a guess.

Fortunately, my GP had a couple of One+ samples lying around and has let me have those to try out and I am about to start that trial. It may well be that these cause a similar reaction and if that's the case, I'll need to see which one is the more bearable. As the Dexcom offering is only in for 10 days at a time versus 15 days for the libre 2 plus, that might give it an edge, but I'll probably know better within 10 days or so.
