the main issue with HCQ is, side effects - heart arrhythmias. (besides protecting supply for lupus and other maintenance users)
The hospitals that are treating with HCQ/Zpak, are doing so as part of a controlled double blind study to learn what the effects vs benefits are. If the regime is prescribed randomly outside a medical environment, outside a study, does that risk adding fuel to the fire of ICU unit demand, with adverse reactions/sudden cardiac issues, coming in needing instant care?
Good post. Arrhythmias are possible and require monitoring.
