I've only had this new sensor on for 2 days but have had to change it as it keeps giving me low alarm!!!! When my mmol is OK. It's obviously due to pressure. What a waste of money.
 
I must admit it’s frustrating when a sensor fails, especially if you are self funding as I do.

If you contact Abbott they will send you a replacement. Hers a link to their online form. https://www.freestyle.abbott/uk-en/support/sensor-support-form.html

Hang on to the old sensor as sometimes they ask for it back. If they want it back they will send you a free post postage kit.
 
I'm already waiting for a replacement from them for the one l changed 3 days ago due to a fault it just wouldn't read. So I doubt the will give me another one because of pressure readings?
 
It’s always worth a try. I would describe the error as low readings which don’t match a fingerprick test and see what they say.

Are you saying the alarms are due to where it’s placed? I.e. pressure lying on it overnight! That can be a real pain. One option if you are sure your BS is fine is to turn the alarms off overnight? It depends what treatment you are on and whether you are certain they are just compression lows. Not much help for the one you’ve removed I know.
 
That's a good idea. I always check when the alarm goes of and it's definitely pressure. I'm on metformin, Alogliptin and dapaglifllizin. So I don't think these cause lows?

I rang up to report one once due to inaccurate readings compared to finger pricks. I mentioned how frustrated I was as I’d just wasted one knocking it off on the door jam. They sent me two, so I defo think they’d replace both of yours.

I'm sure it will be worth a try - don't forget they will be able to see by the app that it has failed so hopefully that should help getting a replacement.

I tried it and they are replacing
 
I'm relatively new to the libra 2, am on my 6th or 7th now. I still request test strips on my repeat prescription, as I prick my finger when I suspect a reading from the Libre 2. I had one with a sensor error after the 60 minute period after fitting. That was replaced FOC, then that failed with a sensor error after 3 days. i was advised I might have to return the defective sensors, but there was no request to return or prepaid box sent. I lost one sensor when I was out with my camera back pack on, I believe putting my arm with shirt sleeves rolled up through the bags shoulder straps knocked it off and it was lost. I'm more careful now after paying £67 for a new one as it was my fault. I'm type 2 on insulin and had a hypo before using the Libre 2, so to guard against this they are useful. After I while I got used to the Libre 2 quirks
 
Are you in the UK? If so if you are on insolin would you not get it on NHS?
 
Hi,

Has anyone had any issues with the libra injecting into your arm?? I've never had this issue before, I'm based in the UK and I'm wondering if I'm all of a sudden doing something wrong....

If it is due to pressure then can you locate it somewhere different?
I sometimes have pressure lows, and it seems a bit hit and miss as to where the best place for the sensor is.
I alternate between arms and try to sleep on different sides but sometimes turn over in my sleep.
I assume that the sensor is on the outside of the upper arm and that you sometimes sleep on your side.
If so, have you considered attaching the sensor on the inside of your upper arm?
Alternative sites may prevent this happening on a regular basis.
 
Since my September post I've had 2 sensor failures immediately after the 1 hour period after attaching to my arm. One failed sensor was replaced FOC within 5 days, and re the most recent one I am waiting for the replacement. As my repeat prescripton is for 2 I attached another mid evening yesterday. I was woken up by the low alarm at 4.30 this morning, pricked my finger and my glucose level was 6.5 so went back to bed. This happens happens fairly regularly, I'm used to it now. They certainly are not very reliable and often give erroneous very low readings, lowest had been 2.8. The sensors are useful but certainly don't match Abbots TV advertising.
