After months of wearing the Dexcom G7 sensors, I have suddenly developed an allergy to the sensor adhesive. Two from the same batch caused angry skin reactions, so I pulled off the second one after only three days and replaced it using a hydrocolloidal barrier bandage. Dexcom is replacing it,and asked for the old one back.
Same thing happened to me when they changed the G6 adhesive long ago and added something I was allegic to. I have four more G7s from the same lot, manufactured in July 2025. Don’t know if it’s just some impurity in the adhesive or if they have changed the formula. So I may have to use the barrier bandage forever, or it may just be this batch. When they change they never admit it publicly, but it leaks out.
Anybody else who just started having the same problem? I know some people have been allergic to the G7 adhesive from the start.
I have tried the Libre3+ and its adhesive did not cause any reaction.
