Libre questions

Just a few questions on Libre. I have never used it.

From what I can tell, it does allow you to share your BG with family, the same as Dexcom. Is that right?

Any major differences between Libre and Dexcom?

Is it compatible with any pumps?

I don’t use Libre, but I got an email a while back announcing that the t:slim X2 pump can now pair with Libre for Control IQ. FreeStyle Libre 2 Plus Sensor & t:slim X2 Compatibility | Tandem Diabetes Care

Resurrecting this thread! I’m seriously considering switching from the Dexcom G7 to the Freestyle Libre 2 Plus (currently the only Libre version compatible with my Tandem pump). I have my next endo appointment in late June, so I’m researching for now.

Here’s info I’m considering. Is there anything I’ve missed?

Libre 2 Plus pros:

Libre 2 Plus cons:

  • Only Freestyle Libre version that currently works with t:slim X2 pump.
  • 1 hour warmup period.
  • Less customizable app and alerts? (ETA My brother switched from Libre to Dexcom because he disliked the app…)
  • ETA: Cannot be calibrated.
  • ETA: Mixed reviews on customer service. Sometimes it’s fine, sometimes it’s horrible.

Dexcom G7 pros:

  • Android App has relatively customizable alerts.
  • 30 minute warmup period.
  • ETA: Can be calibrated.

Dexcom G7 cons:

  • Readings update every 5 minutes.
  • One sensor lasts 10 days.
  • First 12-24 hours on a new sensor can be really erratic and inaccurate in my experience.
  • Dexcom customer service is notoriously not great…
  • Android app has constantly been dropping 2-3 readings per hour (which really means my phone is showing 75% of my readings, even though my pump picks up 100%).
  • Android app Media Volume vs. Notification Volume setting is seriously driving me crazy. I’ve submitted product support queries to Dexcom about it and they haven’t replied.
  • Not the preferred CGM brand through my insurance plan. I’m currently paying $213.96 for a 3-month supply. (The only reason I didn’t try Libre first was t:slim X2 compatibility.)

Here are some questions I still have. Thanks in advance!

I chatted with a couple folks and got mixed opinions.

  • Negative: My brother switched from Libre to Dexcom about a year and a half ago. His experience with Abbott/Freestyle Libre customer service was “a nightmare.” He says it was hard to get replacements. He’s liked Dexcom much better.
  • Neutral: My coworker has been using the Libre for about a year now. She’s found the online replacement forms just fine. One time they asked a follow up question (just like Dexcom sometimes does), but they haven’t denied any of her requests.

My coworker says she needs an overpatch! Her very first night with the Libre it ended up stuck to her pillow instead of her arm. :joy: She’s active and moves around a lot while she sleeps, so it’s essential. On the flipside, her father also uses the Libre but he’s not very active and doesn’t toss and turn at night, and he’s been fine without the overpatch.

@RachelMaraii I use both, I always wear a Dexcom G6, but also a Libre 14 day or Libre 2 a lot for swimming. The 14 day and the 2 are scanned and I put the reader in a waterproof pouch and take it out in the ocean with me.

The LIbre patches have never caused irritation, but neither has the Dexcom. My Omnipods do. I have a lot of adhesive allergies.

The LIbre stays on better on me. My husband has used one and we have to use Skin Tac to make it stay. The LIbre are “popped” off easier by hitting a doorframe or the car seat etc. The Dexcom I use Skin Tac and an overpatch and touch it up with more Skin Tac. But I am wearing my Dexcoms 20-40 days because I restart them. But even not wearing them longer I had trouble on day 2 originally with the Dexcom wanting to come off.

The LIbre can’t be calibrated which is the reason a Dexcom is better. You are stuck with how off a Libre is. Sometimes it’s 10 points, sometimes it’s 30 off depending on the sensor. It’s one reason I wear the Dexcom, I can calibrate it when it needs it. But it can’t read when I’m in the water, hence both.

I like LIbre ap on the phone better than Dexcom ap or clarity on the phone. It tells you a lot more.

Customer service really varies with Abbot/Libre. Sometimes they go in streaks of being nice and sometimes they are a nightmare. They were especially horrible when they first came out. Then they got better, but you really can’t tell what you are going to get in the way of customer service! I never have had trouble getting replacements, but sometimes you have to jump through a few hoops, but most of the time it’s easy. They do have a form online that’s great!

I’ve not had the Libre 2 plus or the G7. I won’t switch until I have to. I had a LIbre just fine before the Dexcom. Interesting enough friends in the UK prefer the LIbre over a Dexcom that doesn’t calibrate because without the calibration it is more accurate. A lot of them had LIbre’s way before Dexcom One (no calibration) became available to them. But some paid for regular Dexcoms themselves so they could have it. The Dexcom is better because of it’s calibration which in the long run can make it pretty accurate.

Same for me. I don’t understand it! I can wear a Dex for 10+ days and not feel anything, but less than 3 days with the pods and they start to itch. It doesn’t make sense. :man_shrugging:

I had no idea about this!! :open_mouth: Tandem confirms – but I would never have realized if you didn’t mention it. Calibrating Your FreeStyle Libre 2 Plus Sensor
