@JessicaD, Imitrex/sumatriptan is not listed as a problem for the G5. A repeated issue like yours is always worrisome, though. I have not heard of anyone having issues either, but I have read of some being worried about using it because they were concerned it might affect their Dexcom. I would give a call to Dexcom to find out what they have to say: it would be good to know for sure Let us know what you find out 🙂
