Especially at the onset of symptoms, but before hospitalization (and an ICU bed) is required?
I understand it can have bad side effects, but that's only after taking it for 6 months or more.
Surely a short-term, two week dosage is safe enough that we shouldn't need a (((doctor's))) evaluation, (((pharmacist's))) approval, and other red tape ($$$) to get it?
