You cannot remove a sensor for a while – once it has come off you need to replace it with a new one. We would suggest that if you manage your diabetes with two or more insulin injections, you should be given access to a flash glucose monitor (Freestyle Libre) or CGM. If you don’t qualify for tech

It’s also worth knowing that sensors only work for individual products, so sensors for a Freestyle Libre won’t work for a Freestyle Libre 2 or another CGM.

Stay Safe: Using the System wrongly might lead to missing serious low or high blood sugar circumstances. It's about safety. If System readings don't match how you feel, use a blood glucose meter. Get medical help when needed. Should know before applying the libre 2 sensor If you live in England, Wales, or Scotland, see the latest guidelines on whether you — or someone you’re supporting— should be eligible for a flash glucose monitor (Freestyle Libre), continuous glucose monitor (CGM) or insulin pump to help manage diabetes. For a complete glycaemic picture, scan once every 8 hours during signal loss when using the FreeStyle LibreLink app. Reader users need to scan once every 8 hours for a complete glycaemic picture. Interfering Substances: Taking vitamin C (ascorbic acid) supplements while wearing the Sensor might give false high glucose readings. More than 500 mg/day could impact Sensor readings, risking missed severe low glucose events. Ascorbic acid is in supplements like multivitamins. Some, like Airborne® and Emergen-C®, have 1000 mg and should not be taken with the Sensor. Consult your healthcare professional to know how long ascorbic acid affects your body. FreeStyle LibreLink works with FreeStyle Libre 2 sensor and is only compatible with NovoPen® 6 and NovoPen Echo® Plus.

Showering or bathing is safe because the FreeStyle Libre 2 Sensor is water resistant, however extra caution might be needed.

Adults with other types of diabetes  

While charging or in regular use, Reader and power adapter can reach up to 120 °F and 117 °F respectively. Avoid holding them for over five minutes. Sensor Water Resistance - IP27: Can withstand immersion into one metre (3 ft) of water up to 30 minutes If it’s your first time opening the app, then you may need to set up an account. Once you’ve done that, hold your phone or device up to the sensor and you should feel it buzz twice. The sensor has been scanned and the app requires 60 minutes to calibrate – so you’ll need to wait that long and then you can use it. Faulty flash and CGM sensors and devices
