Change to composition of adhesive patches has caused severe irritation and open wounds which take weeks to heal. Also new type patches drop after a few days due to the severe allergic reaction. This did not occur when I first started using the previous style patches. Dexcom representatives did not respond to my complaint until fourth communication from me. This is unfortunately no longer a safe, viable product and Dexcom know it. User's recommendation: Don’t use G6 patches.
