Dexcom Stelo sensor failed early: getting a replacement

If a Stelo sensor has a problem before its 15 days are up, Dexcom ships a new one after its technical agent confirms the issue. You report it by signing in to your Stelo account. (Stelo (Dexcom))

What the maker says to do

1. Remove the sensor by peeling the patch from the edge.
2. Sign in to your Stelo account at stelo.com/support and report the product issue.
3. Next time, apply the overpatch and keep it dry for the first 12 hours.

Stelo is sold over the counter in the US only. Dexcom says your primary residence and your Stelo account must be in the US.
