Can someone explain how to put the tegaderm on... and or what tape is best to use for sensors peeling up. Will the added tape remain waterproof? or will it hold moisture? I am only on day 2 of my fourth sensor, and it is coming off. I have only had one sensor work for the full 7 days...I am looking to extend the life span, what the heck am I doing wrong?

Be sure to order the 4 inch wide kind. It covers the entire sensor. Mine is on for the 2nd week.Looks wrinkly but still holding down the sensor. Last sensor lasted 3 weeks and only came off as I was trying to change the old flexfix for a new piece. Probably should just slap on a new piece on top! Good luck. I know you'll love your Dexie like I do.

Done! Thanks.

Placed my order for flexfix, and ordered some skin-tac to go with it. I was able to shower, then prep the sight with the skin-tac (4oz. bottle with applicator), then placed the flexfix(i am alergic to the Dexcom adhesive), then placed the sensor. Went smooth as silk:) The flexfix and skin-tac shipped in two days from American Diabetes Wholesale, in Pompano Beach Florida.

I'll second ADW. I had almost the same order. I just added some of the adhesive remover wipes. Cheapest prices by far and shipped very quickly.

I've used the same advice others have given and pretty much follow the same regimen. Good wipe with alcohol, apply the sensor and cover with flexfix. I just like to use the adhesive remover to get the skintac residue off after applying the flexfix. I usually apply the skintac a little wide to make sure I get good adhesion on the edges of the flexfix.


I clean the area with antibacterial soap, then put on skintac, leaving a circular area a little bigger than the part of the sensor not covered in tape. Let it sit for 5 mins then I slap it on carefully and then tape over it. The skintac helps hold it in place no matter how crappy the tape I end up using is.

That's a smart little system you have there...

i use skin tac to keep my pods and sensors on. apply before pod or sensor, no problems
