These types of anti-viral drugs have never panned out.
If they had they’d be used for the flu.
But they are toxic. They don’t just inhibit viral RNA polymerase.
I’m currently on Plaquenil - (Hydroxychloroquine) 200 mg x 2/day, for CREST syndrome (Rheumatoid/Scleroderma). It has worked very well for me and I hope it is the medicine we need to combat this virus.
The side effects are minimal and the media often confuses the two drugs chloroquine and hydroxycholorquine, I believe purposely.
