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 (, 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.

Just replaced a sensor after 30 days on my 5 yr old. That's our best yet by far. (10ish days is more typical for us.)

Angela, you can get the flexifix tape at American Diabetes. Most people prefer the 4 inch but I like the 2 inch better, plus it is cheaper.

I use opsite flexifix. It stays stuck forever. The drawback is that it gets filthy around the edges. Lucky I'm the only one who has to see it LOL

I get 14 days using tape I could get more but the tape starts giving me an irritating itch that drives me crazy.
@ ed.conlin1: I use uni-solve to remove and clean the area from the crazy adhesive.

I never get much beyond 10 days before it falls off or gives wonky readings, no matter how much tape I put on. I think it's just from lots of long hot days of cycling. I rode 158 miles over 12 hours yesterday on a new sensor that was working well all day.

I was just celebrating starting the third week . . . nowhere near 29 days, but with an active 11 year old I think that's still pretty good!
Comment by jrtpup on August 22, 2011 at 5:59am
29 days. my best yet!

So I've only had the dexcom for about 3 weeks now, but does anyone know hoe shock proof the sensor is. I really like extreme sports. When I was wake boarding last week the sensor almost feel out. But I also like to mountain ski/trick skiing and with winter right around the corner it I fall on it or fall in general will it break. Should I just take it out, but then that is like 6+ hours without it. Any clue. Also what is the easiest way to get of the darn adhesive off my skin after I am done??

Howdy fellow Dex users!
I've been using a Dexcom since 2006 (starting with STS), progressing up to the Seven + now. I find it pretty darned accurate and really appreciate the trends. I typically get 2-3 weeks per sensor with them fading out slowly. I've been a Type 1 for over 55 years and am using an Animas Ping pump. I certainly look forward to when Animas/Dexcom finally come out with their combined unit (after first testing it on the European market). I hope we have some lively discussions here on getting the most out of our Dex! All the best, Jack

What took me so long? Just got my Dexcom in the mail today, set it up, watched the tutorial, put it in and got it all up and running. I love it! about an hour into it actually giving me results it gave me a low Blood Sugar warning. Which I figured was a malfunction cause I "felt fine" but I followed the instructions and did a fingerstick and sure enough, low! On any other day I probably would have miss the "symptoms" completly. I'm a converted and I LOVE IT!
