Moments of Wonderful - …rather than a lifetime of nothing special. A diabetes blog.

You asked. I answered.

I was “Just Talking” to Chris during his time on DSMA Live last week. We were sharing about relying on our CGM devices, sometimes to our own undoing (like when we forget our meters at home).

He mentioned that by the last few days of his sensor life, the adhesive is hardly hanging on. I used to have that problem too. Every few days I would apply a new batch of medical tape to all sides of the adhesive. It was a sticky mess!
Not only that, but I am very sensitive to tape products. I would end up with itchy red burn-like spots if I wore the tape too long.
I can’t remember where, but I read online about a different solution. The product is called Opsite Flexifix and I purchase it on Amazon. I am not a doctor and this is not medical advice. I am just telling you what works for me. Your diabetes may vary.
Here are the supplies you will need (plus a pen, forgot that in the first picture)
supplies you will need

I used an old infusion set box only because the cardstock-like nature of the box provides durability to the template. The first thing you will do is trim off the top of the box.

Lay an old sensor on top of the paper and cut it to make more of a square shape.

Fold the old adhesive under the plastic. Only the gray transmitter cannot be covered using the DexCom system.

Trace the shape of the plastic onto the paper.

Cut the plastic shape out of the template.

Lay the roll of Flexifix over the template.

Cut the Flexifix to the desired size.

Lay the Flexifix under the template and trace the hole of the template onto the Flexifix.

The paper backing of the Flexifix splits down the middle. Peel off one side of the backing and lay it on the skin over the newly applied DexCom sensor adhesive.

Peel off the other side of the backing and press is firmly against the skin.

Peel off the top layer covering over the Flexifix adhesive from the center.

The covering is complete. Enjoy the extended sensor life!

When I use this method, the sensor dies long before the adhesive does. As I mentioned before, my skin is very sensitive. I don’t use IV Prep or other similar products because they give me hives. I have not had any reaction to FlexiFix at this point, and I have been using it for several months.

The only problem I’ve had is the interesting tan lines it is starting to create as the weather is getting warmer!

    I use Torbot SkinTac adhesive wipes, which don’t make me rash horribly (unlike everything else ever) and keep Dex sensors on for WEEKS.

    Fantastically helpful – thank you so much for sharing this!

    And as for those tan lines, just tell people you’ve always been a fan of Cubism. Have an artsy skin tone! 🙂

    One other little tip to go along with this… the sensor is 4×8 squares on the Opsite (if I remember correctly… not looking at my tape at the moment)… so for lazy people like me who use the same technique, but modified, no template needed. Also, if you trim the corners to be curved instead of the sharp 90 degree angles, the corners don’t start to peel up as quickly.

    I’m also a fan of the flexifix tape. That stuff rocks!

    Great idea! Just makes me wonder why in the world the company’s making these sensors don’t come up with something prepackaged so we don’t have to have “craft hour” to get them taped down well.

    I’ve been using Tegaderm over my MM sensor, and I AM allergic to it. So thanks for the link to buy the Flexifix — I’m going to try it.

    Thank you for the advise given as my daughter is only 6 and her patches are starting to lift so we have been using band-aids after band-aids.

    Thank you so much. My last 4 sensors have fallen off before they were dead which sucked!

  • Sally says:

    Yes, I am feeling like George. I had 4 sensors fall off in the last week! They are way too expensive to go thru them that fast. I think we should be reimbursed or given further products to make up for the losses. Yahhhhh that’s the ticket!
