My (b)(6) year old daughter wears a dexcom g6 continuous glucose monitor for her type 1 diabetes.These devices require inserting a sensor into the skin and the sensor is held in place with an adhesive patch that's connected to the sensor.Around the beginning of summer 2020, with a new delivery of sensors from dexcom, my daughter started having a serious adverse reaction to the adhesive on the sensors.It creates a bright red itchy and weeping welt on her arm in the exact shape of the sensor patch.We also had to take the sensors off early as they were itching too bad.I saw posts on a diabetes (b)(6) page of others having the same problem and they noted dexcom had changed their adhesive.Reading that i called and reported it to dexcom.The rep i spoke to confirmed they had changed their adhesive and they were aware of the problem.We continue to get these sensors that cause the same problem and have had to start buying duoderm patches to wear under the dexcom.However, i need to cut a hole in that patch for the sensor to insert through and my daughter still gets a red welt where that cut out is located.So i know dexcom hasn't fixed the problem.This worries me that whatever is in the new adhesive could also be leaching into her skin, either just through contact or through the sensor insertion site or through the raw welt that the adhesive is creating.My daughter's endocrinologist has also had to prescribe a steroid cream to put on these welts to help them heal.Fda safety report id# (b)(4).
