Overview
NOTE: After selecting this product, you will need to complete a short assessment, so we can make sure this medication is suitable for you.
What is the FreeStyle Libre 3 Plus?
The Libre 3 Plus is a small, water-resistant sensor worn on the back of the upper arm. Unlike Flash monitoring, which requires manual scanning, this CGM automatically transmits glucose readings to your smartphone every minute via Bluetooth.
It is designed to help users identify glucose trends, manage fluctuations, and make informed decisions regarding nutrition, activity, and medication. It is clinically approved for use by adults and children (aged 2 and older), including during pregnancy.Key Specifications
- Sensor Life: Up to 15 days of continuous wear.
- Real-Time Data: Glucose readings updated every minute; no routine finger-pricks required.*
- Discreet Design: Approximately the size of two stacked 5p coins (2.9 mm height).
- Connectivity: Seamlessly integrates with the Libre 3 app, LibreView, and LibreLinkUp for sharing data with healthcare teams or carers.
- Automated Insulin Delivery: Compatible with the mylife Loop system (including the YpsoPump and CamAPS FX app).
- Alerts: Customizable alarms for high (hyperglycaemia) and low (hypoglycaemia) glucose levels.
- Note: Finger-prick tests using a blood glucose meter are still required if glucose readings do not match symptoms or expectations.
Directions
Getting Started with the FreeStyle Libre 3 Plus:
1. Check Device Compatibility
Before application, ensure your smartphone is compatible with the FreeStyle Libre 3 app.
- iOS: Download via the App Store.
- Android: Download via Google Play.
- Insulin Pump Users: The Libre 3 Plus is compatible with the mylife CamAPS FX app and mylife YpsoPump for automated insulin delivery.
2. Step-by-Step Sensor Application
The sensor is designed for simple, one-piece application on the back of the upper arm.
- Prepare: Clean the application site with an alcohol wipe and allow it to dry. This ensures the adhesive lasts for the full 15 days.
- Apply: Use the one-piece applicator to firmly press the sensor onto the back of your upper arm. Most users find the process painless.
- Activate: Open the FreeStyle Libre 3 app and follow the on-screen prompts to start the sensor.
- Warm-up: The sensor requires a 60-minute warm-up period before your first glucose reading appears.
3. Monitoring & Alerts
- Real-Time Data: Readings are updated every minute. Unlike older models, no scanning is required to see your current glucose level.
- Custom Alarms: You can set optional alerts for high (hyperglycaemia) or low (hypoglycaemia) levels. These are essential for managing glucose during sleep or physical activity.
- Data Sharing: Use LibreView to securely share reports with your NHS clinical team, or LibreLinkUp to allow family and carers to monitor your readings remotely.
Dosage
Usage time: Each FreeStyle Libre 3 Plus sensor is designed to be worn continuously for up to 15 days. After this period, it should be replaced with a new sensor to ensure accurate glucose readings. Always start the new sensor using the FreeStyle Libre 3 app or reader.
FAQ
What is the difference between the FreeStyle Libre 2 Plus and the Libre 3 Plus?
The primary difference lies in how data is transmitted.
- Libre 3 Plus: Functions as a full Continuous Glucose Monitor (CGM). It automatically sends real-time glucose readings to your smartphone every minute via Bluetooth. It is also significantly smaller and thinner.
- Libre 2 Plus: Operates primarily as Flash Glucose Monitoring. While it features optional Bluetooth alarms, you must manually scan the sensor with your phone or reader to see a glucose reading and update your trend graph.
What makes the FreeStyle Libre 3 Plus "special"?
Compared to the standard Libre 3, the Plus model offers an extended wear-time of 15 days (vs 14 days) and enhanced Bluetooth stability. Crucially for NHS patients using insulin pumps, it is designed to integrate with Automated Insulin Delivery (AID) systems, supporting "closed-loop" therapy.
How many sensors come in a box?
While packaging can vary by supplier, they are typically sold as individual units. For those self-funding a monthly supply, you would usually purchase two sensors to cover a 30-day period.
Can I get the FreeStyle Libre 3 Plus on the NHS?
Yes. Following updated NICE guidelines, most people with Type 1 diabetes and many with Type 2 (who use insulin multiple times daily) are eligible for CGM technology.
Note: Availability may depend on your local Integrated Care Board (ICB) formulary. Speak to your GP or hospital diabetes team to discuss switching to this model.
Can I buy the Libre 3 Plus "over the counter" in the UK?
No. The Libre 3 Plus is not available as a general retail item on supermarket or high-street shelves. However, you can purchase it without a prescription from registered UK online pharmacies or directly from Abbott, provided you complete a medical eligibility declaration (for VAT relief purposes).
Do I need to buy a separate reader?
A separate Reader is not required if you have a compatible smartphone. The FreeStyle Libre 3 app (available on iOS and Android) performs all the functions of a Reader, including displaying real-time data, trend arrows, and historical reports for your doctor.
Compare
Libre 3 vs. Libre 3 Plus
The Libre 3 Plus offers two primary advantages over the standard Libre 3: an extra day of wear (15 days vs. 14) and more robust Bluetooth connectivity, which reduces data drop-outs. It also features improved integration for "closed-loop" insulin pump systems.
Libre 2 Plus vs. Libre 3 Plus
The transition from Libre 2 Plus to 3 Plus moves the user from "Flash" monitoring to "Real-time" monitoring. The 3 Plus is significantly smaller and removes the need to manually scan the sensor to see a reading.
Clinical Accuracy
The FreeStyle Libre 3 Plus is highly accurate, with a MARD (Mean Absolute Relative Difference) of 9.2% in adults. This measurement is the industry standard for CGM precision; the lower the percentage, the closer the sensor is to a lab-grade blood test.
By providing data every 60 seconds, the system allows for tighter glycaemic control and reduced time spent in hypoglycaemia, aligning with NICE (National Institute for Health and Care Excellence) guidelines for diabetes technology.
Side Effects
Information
Abbott accelerates as a global leader in diabetes technology to launch Freestyle Libre 3 Plus. The FDA-approved CGM system serves people from 4 years old to elderly patients with type 1 and type 2 diabetes. It’s water resistant, so you can continue your day, shower, swim, exercise, etc., with no breaks.
The sensor uses a thin, flexible filament to measure interstitial glucose, which is inserted beneath the skin. The data is encrypted prior to transmission via Bluetooth to Android and iOS applications.
The Freestyle Libre 3 Plus system allows patients to reduce their hypoglycemic events and increase their time in range - a direct measure of improved glycemic control. This machine is an excellent instrument for patients and their physicians to develop effective treatment regimens.
