Hola everyone! For the last 3 months we have been using the Dexcom and the first 2 months with NO issues. We were using Skin Tac to stick the sensor the most amount of time possible. The last month has been horrible, skin irritation and itching, sensors not lasting even 7 days. I have tried Opsite Flefix, Tegaderm, Tough pad and nothing lasts more than 3 days. PLEASE, I need some advice.
