FreeStyle Libre 2 Plus FAQs

• How is the FreeStyle Libre 2 Plus sensor applied?

  You apply the FreeStyle Libre 2 Plus sensor using the easy-to-use applicator included with the sensor. The applicator inserts the device just under the skin to measure glucose levels. The process is quick and designed to be comfortable.

• What is the difference between FreeStyle Libre 2 Plus and FreeStyle Libre 3 Plus?

  The FreeStyle Libre 2 Plus is the next generation of the FreeStyle Libre 2, while the FreeStyle Libre 3 Plus is the next generation of the FreeStyle Libre 3 sensor. Both have a 15-day wearable lifespan, but the FreeStyle Libre 3 Plus is smaller. They use different apps: the 2 Plus can be used with an optional reader, the 3 Plus can’t. You can take readings from the FreeStyle Libre 2 Plus by scanning or using the app, while the FreeStyle Libre 3 Plus sends readings without scanning. Which is best for you will depend on your prescription and healthcare advice.

• How many sensors are included in a FreeStyle Libre 2 Plus box?

  Each box contains one sensor, which you can wear for up to 15 days. There’s also a Starter Pack that includes two sensors.

• Is FreeStyle Libre 2 Plus accurate?

  FreeStyle Libre 2 Plus has proven accuracy across the full 15-day wear period. It’s designed to provide reliable readings to support the day-to-day management of your diabetes.

• How does the FreeStyle Libre 2 Plus sensor alert users about glucose levels?

  By setting optional alerts to notify you when your glucose levels fall outside the range you specify, you can stay informed and respond quickly to changes. You will receive an alert on your phone if your glucose moves outside the range you specify.

• Can FreeStyle Libre 2 Plus send alerts to my phone?

  Yes, if you start the sensor using a compatible smartphone, you can set it to send alerts directly to your phone. The sensor and phone must be within range of each other; readings will be sent once they are back within range.

• Can the FreeStyle Libre 2 Plus sensor be worn during exercise?

  The FreeStyle Libre 2 Plus sensor has been designed to stay attached to your arm during all normal daily activities, including exercise. However, very heavy sweating or impact sports may affect how well the sensor stays in place.

• Is the FreeStyle Libre 2 Plus sensor waterproof?

  The FreeStyle Libre 2 Plus sensor is water-resistant, and you can wear it while showering or bathing. However, you shouldn’t submerge it under water deeper than one metre for more than 30 minutes, as this could damage the sensor. This may affect the accuracy of the readings and cause you to miss when your glucose goes out of range.

• Does the FreeStyle Libre 2 Plus sensor require finger-prick tests?

  The FreeStyle Libre 2 Plus CGM sensor doesn’t require you to carry out routine finger-prick testing. But, if your symptoms don’t match the reading on the sensor, you should use a finger-prick test to double-check the levels.

• How does FreeStyle Libre 2 Plus compare with finger-prick testing?

  Finger-prick testing shows a single glucose reading at one point in time. FreeStyle Libre 2 Plus continuously monitors your glucose levels, allowing you to see trends and patterns. This helps you understand how your glucose changes throughout the day and overnight, so you can keep a closer eye on your health.

• How does the FreeStyle Libre 2 Plus sensor compare to other glucose monitoring systems?

  FreeStyle Libre 2 Plus offers a longer wear time than many other CGMs, so you need fewer routine finger pricks. It also provides optional alerts. Other systems may differ in size, wear time or how readings are delivered.

• What should I do if I experience an error with the FreeStyle Libre 2 Plus sensor?

  If you see an error message, follow the instructions in the app or on your reader. If you continue to experience the issue, contact your pharmacy or the manufacturer for further assistance.
