Made in USACommon Issues You May Face While Wearing a Libre 3 Sensor
Nov
The Freestyle Libre 3 and Libre 3 Plus sensors are popular continuous glucose monitoring (CGM) systems that allow you to track their blood glucose levels in real time without the need for routine fingersticks. While this innovative device offers convenience and accuracy, users may encounter some challenges while wearing the sensor. In this blog, we’ll explore common issues you may face while using the Libre 3 sensor, along with tips on how to troubleshoot and resolve them.
1. Sensor Adhesion Problems
One of the most common issues with the Libre 3 sensor is adhesion. Since the sensor is worn on the skin for up to 14 days (or 15 days with Libre 3 Plus), it needs to stay securely attached to provide continuous glucose readings. However, factors such as sweat, friction, and skin type can affect how well the sensor adheres.
Possible Causes:
- Sweat and moisture: If you’re very active, sweat can cause the sensor to loosen or peel off prematurely.
- Skin type: Oily or hairy skin may not provide the best surface for the adhesive to stick.
- Inconsistent application: Not following the sensor application instructions properly can lead to poor adhesion.
Solutions:
- Use adhesive patches: Many people find that using extra adhesive patches or overlays designed for CGMs can help the sensor stay in place longer.
- Clean the skin: Make sure the application site is clean, dry, and free from oils or lotions before applying the sensor.
- Choose a good location: Consider applying the sensor to areas of your body with less friction, such as the back of your arm or the side of your abdomen.
MirTouch Adhesive Patch for Freestyle Libre 1, 2, 3 Sensors
The MirTouch Freestyle Libre adhesive patch is specifically designed to waterproof and protect Libre 3, Libre 3 Plus, Libre 2, Libre 2 Plus, and Libre 1 (14-day) continuous glucose monitoring (CGM) sensors. Made from a thin, hypoallergenic, transparent film, these adhesive patches are designed to last up to 14 days. They help safeguard your sensor from water exposure, prevent sensor malfunctions, and feel comfortable on the skin. Most importantly, they are easy to apply and even easier to remove when using our special skin prep wipes.
2. Inaccurate Glucose Readings
Another common concern is receiving inaccurate glucose readings from the Libre 3 sensor. While CGMs like the Libre 3 are generally accurate, several factors can lead to discrepancies between your sensor readings and your actual blood glucose levels.
Possible Causes:
- Calibration issues: Although the Libre 3 doesn’t require fingerstick calibrations, if the sensor is placed incorrectly or the sensor is not properly positioned in the tissue, it can lead to inaccurate readings.
- Interference from medications: Certain medications or conditions, like vitamin C supplementation or dehydration, can sometimes interfere with sensor performance.
- Temperature extremes: If you expose the sensor to extreme temperatures (e.g., hot showers, saunas, or very cold environments), it may affect the accuracy of the readings.
Solutions:
- Ensure proper placement: When applying the sensor, make sure the needle has been properly inserted under the skin. If you’re unsure, check if the sensor has a firm connection with the skin.
- Keep the sensor within recommended temperature ranges: Avoid exposing the sensor to extreme temperatures, and try to keep the sensor covered if you’re going to be in hot or cold environments.
- Verify with fingersticks: If you notice persistent discrepancies between the Libre 3 and your meter, try performing fingerstick tests for confirmation and consult your healthcare provider if issues persist.
3. Skin Irritation and Allergic Reactions
Some users may experience skin irritation or allergic reactions to the adhesive or materials used in the sensor. This can range from mild redness to more serious rashes or blisters.
Possible Causes:
- Allergic reactions: The adhesive used in the sensor may contain ingredients that cause allergic reactions for sensitive individuals.
- Prolonged wear: Wearing the sensor for long periods can sometimes lead to irritation, especially in areas with high friction.
Solutions:
- Switch to hypoallergenic adhesives: If you are prone to skin reactions, consider using hypoallergenic adhesive patches or adhesive remover wipes that are designed for sensitive skin.
- Allow the skin to rest: When the sensor is removed, give your skin time to recover before applying a new one to a different site.
- Consult a dermatologist: If irritation persists or becomes severe, speak with a healthcare provider to find a suitable solution.
MirTouch Hypoallergenic Adhesive Patches with Barrier Wipes for Freestyle Libre 1, 2, 3 Sensors
Made from breathable, hypoallergenic material, MirTouch patches provide comfortable, long-lasting adhesion to keep your sensor protected and in place for up to two weeks. Moreover, they come with skin barrier wipes. These wipes create a thin film on your skin to which your patch can adhere. This minimizes the possible irritation that comes with the adhesive. The wipes are specifically designed to clean any oil, moisturizer, or residues from the skin prior to application of your patch. Most importantly they make removing the patch easier.
4. Sensor Error Messages
Occasionally, users might encounter error messages on the Libre 3 reader or mobile app, such as “Sensor Error” or “Sensor Expired,” even when they’ve only been wearing the sensor for a few days.
Possible Causes:
- Sensor malfunctions: Like any electronic device, the Libre 3 sensor can experience technical glitches or malfunctions.
- Expired sensor: The sensor has a limited lifespan of 14 days, and if you try to scan it after this period, it will display an expired error message.
- Connectivity issues: The sensor may lose connection with the reader or mobile device due to Bluetooth issues or a weak signal.
Solutions:
- Reboot the reader: Try restarting the reader or app to reset the connection between the sensor and your device.
- Check sensor expiration: Ensure that the sensor hasn’t reached its 14-day limit. If the sensor is expired, you will need to replace it with a new one.
- Reconnect the device: If you’re using a smartphone app, ensure Bluetooth is turned on, and check for any interference or low battery levels on your phone.
5. Difficulty Scanning or Low Signal
In some cases, users may experience trouble scanning the sensor with the reader or their smartphone app. You might notice that the sensor doesn’t provide a reading when scanned, or it takes longer than usual to get a result.
Possible Causes:
- Incorrect positioning: The sensor may not be in an optimal position for scanning.
- Poor Bluetooth signal: If you are using a mobile app, poor Bluetooth connectivity between the sensor and your phone can cause scanning issues.
- Battery depletion: The sensor or the reader may have low battery levels, leading to scanning problems.
Solutions:
- Move the reader closer: Ensure that the reader or phone is close to the sensor when scanning (typically within 1-2 cm).
- Reposition the sensor: Try slightly adjusting your body position to see if that improves the signal.
- Check the battery: Make sure that your scanning device is fully charged.
6. Pain or Discomfort When Inserting the Sensor
Although the insertion process is designed to be quick and minimally painful, some people may experience discomfort or pain during the initial insertion or after the sensor is in place.
Possible Causes:
- Needle insertion: The tiny needle used to insert the sensor may cause discomfort when it penetrates the skin, especially for those who are sensitive.
- Post-insertion soreness: After insertion, some users might experience mild soreness or bruising at the application site.
Solutions:
- Use numbing cream: If you’re particularly sensitive to pain, ask your healthcare provider about using a topical numbing cream before inserting the sensor.
- Apply the sensor correctly: Follow the manufacturer’s instructions carefully to ensure that the sensor is inserted properly to minimize discomfort.

I have had trouble with them coming off and some just stop working. I’m spending money for something I’m not getting. Over time I’ve lost weeks I have paid for and not got.
