It’s not an either-or. The dexamethasone is what you use to reduce respiratory inflammation if the hydroxychloroquine+zinc fails to keep the virus out of the lung tissue.
I have come to the conclusion that HCQ with zinc is an excellent prophylaxis
It is not a great treatment. IL-6 inhibitors, steroids, and heparinization seems to be the ticket for those in extremis.
I remain amazed that a disease so serious can be cured by so many different products.
Is it that serious or is it curing itself over time?
