It will work. Another French study I came across last week had hydroxicloroquine, Zpack (for secondary bacterial infections and pneumonia) and Zinc supplements.
I think French dosage is too high though, it needs to be half of what they use, closer to SK. Less side effects and heart arithmias that way. NY trials should help us to dial in the dose.
That is the one I saw as well. Think they were dosing 3x a day. Can't remember at what Mg the dosage was.
