Event Description

As a type 1 diabetic, i use dexcom g6 sensors to monitor my blood sugar levels.I've used dexcom products for six years, but i've started continuously experiencing adverse side effects from the product as of 1.5 months ago.The blood sugar sensor is attached to my skin through a small oval of gauze with an adhesive to make sure it stays attached to my body for 10 days.For the past six sensor applications, as soon as i attach the gauze with adhesive to my stomach, the skin underneath and around the application site immediately break out into small, red bumps which become incredibly itchy and irritating.The irritating sensation lasts the entire 10 days in which the sensor is attached to my skin.When i remove the gauze and adhesive, the skin underneath is bright red, covered in bumps, and dry.The dryness and irritation lasts approximately one week after i remove the sensor.I have tried changing the positions in which i apply the sensor, and the same result happens in every location.Because of this, my abdomen is covered in red, irritating, dry patches.I need the sensor to accurately monitor my blood sugar, but these side effects are making it very difficult to do so.I believe dexcom changed the adhesive on their gauze and now my skin is having an adverse reaction to the adhesive.Fda safety report id # (b)(4).
