Information

Dexcom Users

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 (http://www.cr3diabetes.org), 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.

Thanks for all the feedback. I really appreciate it. I had called Dexcom Support but got the impression that it must have been something I was doing wrong. But, it looks like that was a load of rubbish. The dexcom rep also told me that the demo unit was an older unit, and may have been nearing the end of its' life? Which I find questionable, as it was a demo, presumably intended to exhibit its desireability??
From this I deduce that the dexcom is somewhat of a general guide, but is not a dependable item at this point in its' evolution.
It was worth a try thought, I learned a lot. Thanks to all who gave me their input.

I find that the Dex is pretty accurate most of the time, although I also have had some pretty weird numbers! They are rare. When I used the Medtronic CGM, it was rare that my numbers were even close to accurate. My endo suggested the Dex, because in her experience "some bodies chemistry work better with the Dex, and some work better with Medtronic.

As much as I love my Dex, I wish that it was more trustworthy! Have had it for about a month, and can't imagine being without it. But, I did have a steady 120 reading on Dex and did a fingerstick - 42! Did a double take because I couldn't believe or feel it and came up with 45 again on a fingerstick.

Hi - Did you take Tylenol? That will do it. Something in the chemicals throws off the CGM.

Sometimes the Dex is right on the mark... and other times it is so off. The main thing is to not believe it when correction bolus or when treating lows. I have gotten lazy and ties and believed the middle of night alarms, only to wake up in bad shape.Hopefully , they will get better with time.

Me also had a higher reading than I test on my fingers. In the night my CGM vibrated and showed that it is 370, but I checked my sugar it was 140.

Comment by Jennifer on December 20, 2011 at 9:08am

Does anyone have a higher reading than when you test on your fingers? Mine is away off. This morning it read over 300 and I checked my sugar and it was 160.

Comment by Natasha Bowlds on December 14, 2011 at 10:33am

It's just Tricare Prime - I was just responding to Sandy about that. Unfortunately I don't think it's related to your issue of Medicare coverage. The people I know on Medicare with type 1 also pay out of pocket for the Dexcom. sorry.
