Our response to barrier creams or sprays affecting the performance of FreeStyle Libre glucose monitoring sensor


Users of FreeStyle Libre Flash glucose monitoring systems by Abbott experiencing skin reactions. 

Some users of FreeStyle Libre Flash glucose monitoring systems by Abbott have reportedly been experiencing skin reactions to the adhesive on the sensors. To reduce irritation, some users have used barriers creams or sprays which is thought to have affected the performance of the device.

Libby Dowling is Senior Clinical Advisor at Diabetes UK. She said:

“People with diabetes who use Flash should be aware that, as per recent reports, using barrier creams or sprays could affect the performance of their glucose monitoring sensors. If people are having skin reactions, they should consult with their healthcare professional or pharmacist in order to get advice on the measures they should take for the performance of their device to not be affected. 

“We’re reassured that the manufacturer is currently revising the formulation of the adhesive and is looking to make this available to the public in response.”
