Tip: How to Stop Your FreeStyle Libre Sensor From Falling Off Before the 14-day Expiry?

Tips to have your Libre and Libre 2 Survive 14 Days

I have had a few questions from readers on tips to keep their Abbott FreeStyle Libre and Libre 2 from falling or being knocked off before the 14-day expiry. Here are a few tips I have been using to help keep my Libre Sensor from falling or being knocked off of the back of your arm since 2018.

Have I been successful with these tips? I will let you decided, however, I have been using Freestyle Libre for over 2 years and have only had an issue with one sensor that accidentally got caught in my shirt as I was taking it off.

DISCLAIMER: These tips may not work with everyone, as we all have different skin types. However, they have worked well for me. Further, these tips do not replace the official instructions provided by Abbott and may not work for everyone. I can not be held responsible for any sensor coming off early or being damaged. Note: For convenience, I have included links to my Amazon Store where you can purchase many of the items suggested. Looking for accessories for your FreeStyle Libre – look here.

Tip 1: Hair is our enemy, start with a blank slate

Hair gets in-between the skin & sensor adhesive. This is where your wives or girlfriends can get a bit of pleasure and help remove the hair from a small area to ensure the Libre or Freestyle Libre 2 Sensor has skin to skin contact.

Good clean, dry, skin to skin contact is critical. Bring out the hot wax! LOL, however, a razer works just as well.

Tip 2: Ensure the Libre sensor area is clean and dry

The FreeStyle Libre, Libre 14-day, and Libre 2 work best when the skin is clean, dry, and oil and sweat-free by using the two supplied alcohol wipes. This includes removing any residue left over from your last Libre Sensor.

If you use Skin-Tac or similar products, you can also try  Skin Tac Adhesive Remover Wipes  – this unique formula effectively removes even the most stubborn adhesive residue leaving the skin clean, dry, and without a greasy film.

Tip 3: Pre-treat the Libre Sensor area with Skin Tac or similar

If you are finding that your Libre or Libre 2 sensor is not sticking well or causing some skin irritation pre-treat the skin with Skin Tac Adhesive Barrier Wipes  barrier prep wipes to improve the adhesion of the Libre sensor to your arm.

Skin Tac Adhesive Barrier Prep Wipes has two main uses:

  • They provide a tacky surface for you to easily fix any dressings or tapes to (or our Libre), and
  • They provide an effective barrier between your skin and those dressings that may be causing irritation.

Tip 4: Smooth the edges around yours Libre with a Blunt Object

After you have applied your FreeStyle Libre, press around the edges of the Libre adhesive with a blunt object such as the end of a spoon. This will help reduce the chances of an edge starting to lift.

Special thanks to Nerdabetic for this great tip.

Tip 5: Wait one hour before getting you Libre Sensor wet

To give the adhesive the best chance of success – try to wait at least one hour after applying a new sensor before you get it wet. That could be as simple as having a shower or going for a swim. This also includes exercise — let’s keep sweat away from our sensors for at least an hour. Similarily, I do not put on my sensor immediatly after my shower. I give my skin a half hour to an hour to dry before I put on a new sensor.

Tip 6: Pay attention to lifting edges of your Libre adhesive

Watch the edges around your FreeStyle Libre for loose adhesive. Add kinesiology tape or a patch to help it last the remainder of your 14 days.

You may notice that although your Libre or Libre 2 is securely attached, there may be some minor lifting around the edges of your Libre Sensor. These little edge lifts are usually the culprit of people ”losing” a sensor early, as it is much easier for a shirt sleeve or oddly positioned door frame to get under that loose edge and OUCH – you pop it off.

It is critical that you pay attention to lifting edges of your FreeStyle Libre or Libre 2 sensor over the entire 14-day period.

At this point (usually around day ten), I occasionally need to add a protective barrier over-top of my Libre sensor. (Step 7)

Tip 7: Protect your Libre – give it a helping hand with tape

Let’s admit it, we catch, bang, or shower our Libre sensors daily. Even the best products need TLC to last the 14 days and not fall off. Pay attention to your Libre and Libre 2 sensors and in particular, the edges of the adhesive (Step 6) – I firmly believe this is our responsibility as Libre users.

What to do if your Libre sensor starts to come loose or the edges around the sensor start to lift?

I typically go the simple approach and use a small piece of Kinesiology (i.e. KT Tape ) over my sensor. However, there are other products available such as Patchabetes , RockDex, or SimPatch  which are designed to cover the Libre and Libre 2 sensor with a protective bandage.

I have also heard other FreeStyle Libre users have had great success with Tegaderm  which is a transparent waterproof adhesive wound dressing; similar to what you would have over-top of an IV.

For those that choose the kinesiology tape — I recommend rounding off the edges. This will significantly increase the length of time it sticks. Secondly, trim off any loose edges as they start to come loose.

Warning: Be cautious not to pull on your Libre when removing any patch or tape!

My biggest concern with any of these products is that they adhere to both your arm and the sensor. Fortunately, I rarely need to remove the bandage from the sensor as they have lasted the remainder of my 14-day sensor lifespan. For that reason alone I would never put a patch on day one. I find my Libre stick well for the first 7-10 days before the edges start to lift up. I then throw a patch or tape over-top for the last few days to more protect that one little cover where we undoubtedly will get a shirt sleeve or door frame caught underneath.

If you do need to remove the patch or tape before you sensor has expired – I have found that slow and steady wins the race. Be sure not to tug or pull on the sensor.

Hint: Try placing a small piece of gauze between the patch and the Libre or Libre 2 sensor. This should help with reducing the amount of stick to the Libre and assist when changing the patch before your sensor is due to be replaced

No matter what you choose, the key is to help keep the edges of the Libre sensor secure and protected.

What to do if your Libre Sensor Falls Off Early

Contact your local Abbott Customer Service Centre if your FreeStyle Libre, Libre 14-day, or Libre 2 sensor for any of the following reasons:

  • Your Sensor is routinely off by more than 20% when compared to a blood glucose test. Remember, you need to test your blood and then your Libre with a scan 10 minutes later to accommodate the lag between interstitial fluids and blood glucose
  • You are getting errors when trying to read your sensor. If you have a second device, ie a phone, or the Libre Reader. Test both to help determine if it is the sensor or your reader device that is acting up.
  • You knocked off your sensor
  • Your sensor fell off

The FreeStyle Libre representative will discuss and let you know what replacement options, if any, are available to you.

Here are the local contact numbers for Libre Customer Service / Support:

As I opened – using these seven tricks, I have never lost a Libre sensor. The one and only sensors I did loose was a human error as I skipped step 6 as I knew one edge was pulling loose.

    • Hi Brenda! It is my understanding that as of March 2021, the Phone app for Libre 2 is still not available in the US. As Libre is considered a medical device, both the sensor and any applications are required to be approved by the FDA.

      Keep your ears posted.
