Hmmm…
Very interesting…DexCom is technically way more than you would need. While, in theory, a low blood sugar could happen with metformin, it is very nearly impossible. The price difference between the DexCom and the Libre is huge. (I wonder how big THAT rebate is for CVS to put them as preferred).
DexCom is a bells and whistles continuous glucose sensor whereas Libre (as they are currently) are more of a glorified glucose meter. It looks like it is a CVS wide thing (not just limited to your plan). I’m curious to see what CVS is going to do…I have yet to come across any insurance (or pharmacy benefit manager) that allows DexCom if the person is not using insulin. (So be prepared for the possibility of dealing with that too).
