The freestyle libre sensor has been used for over a year with no problem.Starting sometime in (b)(6), the disk would come off sooner that it should (it lasts 2 weeks before replacement), and underneath the disk, in the exact shape of the disk, was an acid like burn on the skin of the arm.It consisted of bright red, blistered, raised lesions on the skin in the exact circle of the disk.This has happened four times, with four different disks.In calling the company, they said that sometimes they change the adhesive to make it more sticky.Whatever they've changed it to is causing the skin to be greatly compromised.The most recent disk had sn (b)(4) expiring 8-31-2020.The patient has nka and can use any bandaid without issue; no latex allergy.Fda safety report id# (b)(4).
