I have never heard about a doctor who treats ME/CFS with remdesivir. A course of remdesivir against COVID-19 costs several thousands of dollars, so taking this as some form of maintenance therapy for ME/CFS would be hugely expensive, not to mention it has to be administered IV.
I don't think there is really anything we can do about it, there isn't enough remdesivir to even treat COVID-19 patients.
The first step would be to demonstrate that remdesivir actually has any effect in ME/CFS, so far there is no evidence.
