Chemist 4 U don't just use manufacturer's descriptions. We use medical content writers to research the products and provide useful information in an easy to understand format.
We then have our qualified pharmacists check the content for both quality and accuracy.
We think that this is the level of service our customers should expect from us.
We don't think you should accept any less online.
What is the Freestyle Libre One Sensor?
The Freestyle Libre Sensor is an easy-to-use sensor for testing blood sugar levels for those with diabetes. Instead of the more traditional blood testing method, the Libre doesn’t require any finger pricking to draw blood and instead, the sensor sits on the back of the arm where it can easily be scanned in order to give you a reading. It can be used for up to 14 days.
How does the sensor work?
This sensor works by placing the Freestyle Libre Reader (sold separately) over the sensor which gives off a reading. It works similar to how a contactless credit/debit card works, with a simple connection in order to confirm the purchase.
Who is this sensor suitable for?
The Freestyle Libre Sensor is suitable for those with diabetes who have a more active lifestyle and want a faster reading. It is also suitable for those who perhaps don’t want to be constantly pricking their finger for blood.
How is the Freestyle Libre Sensor applied?
The is applied to the skin using the included applicator. To do this, make sure that the skin is clean because oily, wet, or hairy skin may make the sensor harder to apply. Applying the sensor includes a number of steps:
- Open up the Sensor Pack and unscrew the cap on it and then put the cap aside.
- Line up the dark marks on both the sensor and the applicator and press down on the applicator until it stops.
- Place the applicator over where you want the sensor to go and push down firmly in order to apply the sensor to the skin. Now the sensor should stick to the skin.
- Gently pull the applicator away from the sensor, which should stay on the skin.
- Put the cap back onto the applicator.
How do I shower or bathe when the sensor is on?
If you are showering or bathing, then take extra care. The sensor is waterproof but hard pulling can knock it off, particularly when towelling. The sensor is waterproof for up to 1 metre and can be in water for up to 30 minutes.
Will the sensor work when I am wearing tight clothing?
No, avoid wearing tight clothing on the arms when using the sensor. Also, take care not to catch the sensor on clothing when getting dressed.
Can I play sports when using the sensor?
You should avoid contact sports that could potentially knock the sensor off the arm. You should also be careful not to bump into things when not doing exercise as this could also knock the sensor off.
Can wear my sensor or CGM device on a plane?
If you wear a Freestyle Libre Sensor or another CGM (continuous glucose monitoring) device, then you may be concerned about taking the sensor through airport security or onto a plane. However, you should be able to take your sensor and other essential products you may need to manage your diabetes (e.g. an insulin pump) onto a plane with you. We’d recommend contacting the airport and airline you will be flying with so you can make them aware that you have diabetes and will need to take supplies with you, so they can give you more information about their policies in this area and help you to navigate the airport security process properly when you’re there. You should also carry documentation from your doctor or nurse which explains your condition and further information about the device you’re carrying. For more information about this, you should speak to your doctor or another health care professional.
How do I remove the Freestyle Libre Sensor?
In order to remove the sensor, use an adhesive remover or use a baby oil such as Johnson’s Baby Oil in order to help remove the sensor.

The severity of the skin reaction can vary from person to person and for certain users this is a skin hypersensitivity reaction rather than an irritation reaction. For this type of reaction, once the person has become sensitised to the adhesive, every time the sensor is reapplied a skin reaction will occur. With each reapplication, the symptoms might appear more quickly and may worsen.
The manufacturer has confirmed that they have revised the formulation of the adhesive, which will be available to UK customers from April 2019.
Please note this problem may not be unique to the Abbott FreeStyle Libre sensor adhesive.
The same actions should be taken if patients experience similar symptoms with a different brand of
continuous glucose monitoring system.
In February 2019, the DVLA updated their regulations to include Group 1 drivers to use Flash Glucose Monitoring systems for the purposes of driving. Drivers must not actively use a glucose monitoring system whilst driving a vehicle, instead you must pull over in a safe location before checking your device. Drivers using the FreeStyle Libre flash glucose monitoring system must get a confirmatory finger prick glucose level in the following circumstances:
• If your glucose level is 4.0mmol/L or below.
• If you have symptoms of hypoglycaemia.
• If your glucose monitoring system gives a reading that is not consistent with your symptoms.
• If you are aware that you have become hypoglycaemic or have indication of impending hypoglycaemia.
• During times of rapidly changing glucose levels
Group 2 drivers must continue to use finger prick testing for the purposes of driving. Flash Glucose Monitoring systems are not legally permitted for the purposes of Group 2 driving.

The sensor is 5mm in height and 35mm in diameter.
The portion of the sensor that gets inserted under the skin is less than 0,4 mm wide and it's inserted only about 5mm under the skin.
In a study conducted by Abbott Diabetes Care, users agreed that inserting the sensor was no more painful than a typical finger prick glucose test*.
