I believe they are the same. The G4 ones that I have left are also compatible with G5 even back in 2016.

@Peg I personally donāt know when the sensors become ineffective - I am not scientific enough to break it down. I have however used sensors that were 1-2 years past shelf life with no problems in the past.

@Peg, if no one is able to test some of your sensors, we will find a way to get a few of your old ones here (we have friends visiting every few weeks from the US). Hopefully a US resident can do it though.
I am guessing most if not all of your sensors are still good. It will be interesting to see if they are noisier or donāt last as long though.
Iām always open to being a test rat

I have some that expired 2/27/16. My daughter hated them so I didnāt force her to use them but couldnāt get myself to toss them I would love to know of they still work if anyone would be interested I could send them out. They are Medtronic enlite.

A post was split to a new message: Expired sensors
I was browsing this forum because i have a 2021 dexcom g5 sensor that i was wondering if it was safe to use for a day (or longer if it works) while I wait for Walgreens to open up tomorrow. I didnāt realize I was out & my pharmacy closed for the day.
I guess since Iām not seeing an answer of one that old, Iāll let you all know if it works or not.

What do you have to lose? :). I would fire it right up and get as much life as i could.

Thanks for the encouragement.
I just started it. I had to add a new transmitter as I was doing this. The sensor placed perfectly on me. Hopefully it wonāt keep me up all night. Iāll let everyone know how it goes.

I forgot to write back but the 10 days with the 3 year old sensor & the brand new transmitter worked fantastic.
