I am having issues with the glue that attaches the sensor to the white sticky pad that attaches to my body. I literally get an outline of the glue pattern. I have tried tegaderm but it doesn't seem to help. Any suggestions?

All I can say about that skin reaction is EEEEEK!!! But I'm glad you found a solution. When I first started pumping, and turned out to be allergic to Tegaderm (before IV3000 came out, and when you HAD to cover the infusion site with something), I used to use Hypafix in much the same manner -- cutting out a corner of the thing folded in fourths. Hypafix on the bottom, then the set, and then the Tegaderm on top, without touching my skin in any way.

Nowadays, I'm using IV3000, and so far, so good. I hope I don't become allergic to it later! :-)

I'm wondering if there is a wound-care nurse specialist at your hospital. They care for patients with ostomies who MUST use an adhesive on their stomas for possibly the rest of their lives, and these nurses would be most familiar with products that the rest of us don't even know about. Just a thought.

I too have been having reactions and the sensors trying to fall off. My reactions have a severe rash associated with them. When you remove the pad, the rash is raw and weeping. I just met with the Dexcom educator and she gave me some ideas. She stated that she had one woman that nothing she did would stop the reaction until she used the Hipaclens. Evidently, it kills off unwanted bacteria far better than regular alcohol wipes.

For the itching:
She said to wash the area with Hipaclens. Be sure to wash a 6" radius and to dry perfectly before applying the sensor.
Alternatively, if it is just slightly bothersome, use Benadryl spray after washing the area and drying. Let the spray dry completely then apply the sensor. You can also apply the spray to the outside of the white sensor pad later in the week if it is bothering you. Just be sure to protect the transmitter and canula area.

For sticking issues:
Use IV-Prep wipes. These wipes have a sticky type alcohol solution. After it is dry, it is tacky and grips the white sensor pad. Be sure to rub the IV-Prep in a donut fashion, leaving the center free of tack for the canula and sensor section free and clear.
I plan on trying these methods on my next change out.
Good luck everyone!

I responded to this group almost a month ago for the same issue and how I was successfully resolving it. And I can not find that response.

You need a skin barrier between the adhesive from the DexCom and your skin.

Here is part of what I wrote last month;

The DexCom Sensor adhesive, starts to itch like crazy after 2 days. I thought I had to man-up or cowboy-up and just give it more time or try different places, and the result was always the same, or worse.

I remembered that some people had talked about putting an IV3000 1-hand bandage on themselves before putting on their equipment. I thought it was a little extreme at that time, but this morning, I gave it a second thought.

I prepped a site. I made a small hole on the IV3000, so that no adhesive would touch my skin. With really good light and great reading glasses, I put the DexCom inserter right where I had made the little hole on the IV3000. (fold into fourths and snip the little tip of the corner, see picture.) I inserted.

I have now done this for several weeks and have only had 1 slight reaction. That reaction came after 5 days and I simply switched out that sensor, again using this barrier technique.

I hope this helps and please let me know if it does. I will check later on to see if this got posted.

Good luck and Good skin,


I have some of the IV3000 bandages but after wearing them for less than an hour, they start to peel up. If I take a shower, they just roll into a ball. I wonder if they go bad? I have had them for just over a year. Seems unlikely but you never can tell.

I've had mine for a couple of years without a problem. Are you making sure your skin is completely dry before applying? I had trouble with that. I'd use Bard or a barrier wipe, and then not wait until the skin was completely dry. Also, I pat in the shower vs rubbing. HTH

Usually the peel up is a result of applying it too soon after using an IV prep wipe, or with skin that is not freshly clean and dried. After using the IV prep wipe on clean skin it is recommended that you wait 1 minute before applying the I-3000 1hand bandage (or your favorite dvice with adhesive.

After I do that, I then wipe the top of the bandage to be sure that the edges stay down and also to prep the bandage for my DexCom after another minute passes.

I try to be careful but i get peel ups also. So if I can I take a shower of clean off the area and then use the IV Prep Wipe over everything, and then slap another I-3000 over everthing. And that usually keeps everything in place.

Do they age or wear out? probably. heat will do it. lack of humidity will do it, age will do it. They only cost about $5 for a box, but the supply companies can charge your insurance $50 for the same box.

Whover you get them from, say that they are failing and you want them to exchange what you have for a fresh box.

That should take that variable out of the equation.


Does anyone have red whelps come up from the sensor thing that goes in your skin? I been having that and now I have scars. I am also on the pod and it does not do that to me? I dont want to stop using it because I depend on it so much.

Yes! See my response above. It might help.

I have also been on the phone with DexCom about this, and it appears as though their corporate support group have heard about this.

It would help if people would put calls into their corporate general support line. If you have to terminate using a sensor because of a reaction, many times they will send you a replacement for that sensor.

If they receive a larger number of calls, however, there will be motivation for them to take a second look at their formula for their adhesive.

I have asked for adhesive formula and got a polite distractor and if the representitive can get it he will email it to me. But, I am sensing that that request hit like a bug on a windshield on the highway.

We need more calls to corporate support lines. And if that fails, some calls to the FDA. Change is required.

And I feel for everyone's position in this.

Good luck and this too can be resolved,


I have been using the barrier wipe and still got scars from the cannula thing from the dex.

I have heard of the Bard Barrier wipe and I have never tried them. I have also heard of people not having success with them.

A wipe that leaves a magic protective barrier does not sound like it would have the reliability of solid bandage shiel like the I-3000, 1-hand. It is a little tricky to make the small hole in it for the canula for any of the pump systems or for the Dexcom CGM, but I have found that it works for me.

And I have a great deal of allergies, especially to the DexCom adhesive.
