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 don’t 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 don’t last as long though. ---

I’m always open to being a test rat 🐀 ---

I have some that expired 2/27/16. My daughter hated them so I didn’t force her to use them but couldn’t 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. ---

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 didn’t realize I was out & my pharmacy closed for the day. I guess since I’m not seeing an answer of one that old, I’ll 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 won’t keep me up all night. I’ll 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. [Previous page](https://forum.fudiabetes.org/t/expired-dexcom-sensors-work-fine/1688.md?page=1)
