Merry Blood Sugar!
I woke up Christmas morning with my Dexcom reading a truly god-awful number that I didn’t deserve (I ate well the night before! Bolused properly! WTF?!). I was upset and disappointed to start the day on such a bad note. But then I realized that I didn’t have any other high symptoms, and my Dex sensor site felt suspiciously tender – I’d definitely slept on it wrong. So I got up, went to the kitchen, and tested on my real meter. Much better. I got a great Christmas present when the true number came up. Oh, and the other gifts were pretty doggone good too! Happy Holidays everyone!

Jason I think anything with acetametaphine (which is the active ingredient in Tylenol) in it can give a false high on the Dex. Personally I’ve just had two kind of not-so-awesome sensors in a row, and then I realized the ones I’m using expired in September, so I’m wondering if they really are that sensitive to their expiration dates! Not good if so, since I stockpiled quite a few of them over the course of the last few months and have 12+ sensors with 2012 expiration dates.
I had a similar false high on my Dexcom during the day earlier this month. It spiked after I took something for a headache which I attributed to the caplet coating. Testing with my BG meter, I found nothing out of the ordinary so I was relieved. The sensor worked fine for the rest of its life. Being relatively new to my Dexcom, I wonder how often this issue happens?
