For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (, which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

Silver is known to be somewhat toxic, but you are typically exposed to much much larger quantities without problems (wound dressing, older teeth fillings, eating in silverware, etc...) Platinum is not an issue - huge quantities are very well tolerated: hips prosthesis for example, plus a ton of other application in orthopedic surgery.

As I know the sensor wire is in silver and platinum ... and polymer too.. but im not sure the material in polymer..
Do you know if any reported the leak risk of these metals in your body? Do they reported quantity of metal that is leaked in average in 7 days?

Thank you

I updated on Friday and just restarted the sensor I was already wearing which was 12 days old at the time. Saturday morning though the sensor got an extended period of ??? so I ended up having to change it out before a tennis match. The first 24 hours of this sensor were awful with terrible Dex confusion, but it has been very accurate since then. I will find out next Saturday if it is still easy to just restart the sensor. I'm used to getting 3-4 weeks from one.

Wondering...has everyone who upgraded to 505 been able to extend their sensor life as before the upgrade?

Thanks Clare

I appreciate knowing that I was not the only one who was getting LOW and HIGH Alarms when my BG was OK.
NOW, the Dexcom G4 with the 505 is working very well.
After 28+ years with Type I DM, the OmniPod pump and Dexcom are making a significant difference for me.
I encourage folks to hang in through the adjustment time.

I believe it is the US dishers but I am not completely sure.

Comment by dishers on November 10, 2014 at 8:33am
The update is it for the Us and Canada?
Comment by Clare on November 10, 2014 at 7:10am

Here is the link to the download. I have found it to be a lot more responsive when recovering from a low.

My husband got it from the Dexcom website!
