Huh. I'm on 200mg/day for rheumatoid arthritis.
I wonder if I ought to double dose for a while.
There are a fair amount of studies who took the initial in vitro results (i.e. cell culture) suggesting non-specific antiviral activity (at that level coca-cola is also an antiviral, antimicrobial, and antitumoral, by the way), into animal or human, and they just did not pan out, because it isn't an antiviral.
I'll ask my rheumatologist about increasing the dose. In case I get infected, have trouble breathing, and can't get hospital care.
