16 Dexcom G6 failed

I was only taking 40mg a day.

If you’re still taking the 40mg you might try splitting it in half (20mg in am, 20mg in pm)

Taking it all at once must make you pee like a racehorse :slightly_frowning_face:

I just want to add, if you have a sensor that is working for you, extend it’s life and restart it! I don’t have a problem with them failing, but I do restart them all the time and the accuracy is better from day 2 on (until they finally cave). So I suggest if you have one working well, keep it on and keep restarting it until it fails. That way you don’t have to mess with the next one not working as well.

When I restart them I just have to recalibrate on day 1 and day 2 of each restart. For some people it might be different.

Great post! I’ve used a Minimed pump for 15 years, the last couple with the Minimed CGM. I have so many challenges with the sensors. Sometimes connect properly and then stop working a day later. Other times never connect at all. And my 670 pump…I’ve had three in 9 months. They simply stop working.
So! When the warranty runs out in December I plan to move on to the T-Slim and Dexcom. Yes?!

I also plan to move to T-slim.

You can check this topic regarding others using T-slim with Basal-IQ.

@DrBB: you wrote “we know acetaminophen can cause problems” - but Dexcom claims that while acetaminophen interferes with the G5 sensor, the G6 sensor is not affected by acetaminophen. Have you (or anyone else reading this) had acetaminophen/G6 issues?

I don’t take acetaminophen very often, but I do on occasion and haven’t noticed any issue with it. I have the G6.

Yes, glad you point that out. I just meant it as a general acknowledgment that sensors can be sensitive to some drug interactions, and it’s possible not all of those interactions are known or documented.

I avoid acetaminophen anyway. Anything that can kill your liver if you accidentally take too much shouldn’t be an OTC drug, IMO.

I have had signifiant issues with G6 sensors. Recently, tech service has asked if I use acetaminophen. I do (rarely) take medication that contains it and the dosage totals 1,000mg, which Dexcom indicated is at the minimum that would begin to affect the G6. So, while Dexcom says that they’ve eliminated the acetaminophen effect for the G6, I think they’ve just minimized it to beyond the recommended Tylenol max 8 hour dosage. My guess. Jessica

PS - as a general comment, I will note that moving the sensor from my abdomen to my upper arm has gone VERY WELL - and that I’ve gone through one sensor with no failures and am a few days into sensor #2! Feeling good about that. Still having the crazy day one LOW calibration issues, though - not fun.

Although I am using the G5 and still can’t take any Tylenol, that’s interesting to know about the G6. Thank you!

I have the Dexcom G6. Sensors fail regularly (on average 2 per month). While Dexcom does replace them, the techs ALWAYS ask if I’ve had acetaminophen. And if I say yes, each time they warn that acetaminophen can interfere with the G6. That doesn’t explain the failures when I’ve avoided it. I rely on the technology, but it is far from perfect.

Since starting the G6, I started taking acetaminophen again, without issues.

Same here. I take it daily for arthritis without issue.

They ask me about acetaminophen when I call as well. But there are not supposed to be issues unless you take very high doses.

From Dexcom website

Interfering Substance Risks

In previous generations of Dexcom CGM systems (G4/G5), acetaminophen could affect your sensor readings, making them look higher than they really were. However, with the G6, you can take a standard or maximum acetaminophen dose of 1 gram (1,000mg) every 6 hours and still use the G6 readings to make treatment decisions. Taking higher than the maximum dose of acetaminophen (e.g. > 1 gram every 6 hours in adults) may affect the G6 readings and make them look higher than they really are.

I have been wearing the Dexcom on my arm for the last 4 years. Never had a problem.

Good to hear, @Barb24! I’ve had 0 sensor errors, too, since I moved the Dexcom sensor to my arm! :slight_smile: I’m on my 3rd sensor now with no errors.

I also wear them on my arm and I’ve only had one that went to errors. I do restart them all the time too.

Good to hear @Marie20! I haven’t restarted any yet but hope to have a chance at it assuming they last :slight_smile:

They are so much more accurate when you restart them too, although after about 12 hours I do still have to do one calibration. I think because of my Libre days I have the belief you want the good ones to keep going!

Yay @Trying! I am at 0 sensor errors on my arm as well! Whoo! May even try for a re-start?! (I did try for one earlier, but my transmitter was almost finished so there was a screwy error and I threw in the towel… will start fresh with this new transmitter! Fingers crossed!). Hope you’re doing well! Jessica

I was thinking the same thing!! Hope this keeps up for the both of us!
