Yep, you bet, whether it's prophylactically or because you actually have this "illness" (perceived or otherwise, I guess).

It is cheap (or it WAS so hopefully it will stay that way but look, we're dealing with drug companies here) and it works.  It has to be administered per a prescription, however, so you hafta find a sensible doctor who will actually prescribe it for EITHER of the above reasons.  When you take it as a prophylactic, you only take it for about 2 weeks or so, at least that's my understanding.  Can't see why ANY doctor wouldn't agree to that. 

If you actually already have Corona (and NO ONE KNOWS THAT FOR SURE BECAUSE THE TESTING IS SO DAMNED BOGUS) I have no idea how long you're supposed to take the stuff, but any good doctor should be able to tell you the truth about that.
