Pretty sure Remdesivir isn’t under EUA approval.
In any case, no off-label drug use should be off the table if one’s doctor thinks it is effective. Sadly, this isn’t the case for far too many doctors it seems.
That said, I view relying on any potential treatment as a poor substitute for vaccination.
The EUA for Remdesivir is on that page, down towards the bottom. You will see it beside the date 05/01/2020
