This is interesting from America's Frontllne Doctors:
"The safety of HCQ is irrefutable. The evidence supporting HCQ efficacy against Covid-19 is also overwhelming. All negative HCQ studies have used either: too much, used it alone (it needs Zinc), or used it late (it should be early.) The treatment dose is 200 mg HCQ twice a day for five days + Zinc 50 (elemental) daily. The prophylactic dose is 400 mg HCQ weekly + Zinc 50 (elemental) daily. (There are studies right now to see if HCQ 200 mg. weekly is sufficient.) This is very low dose. (The usual dose of HCQ in Lupus, Rheumatoid Arthritis is 400 mg. daily for years.) There are telemedicine physicians who are aware of the facts and if you are concerned about this, please see one. It is also over the counter in many places in the world including Indonesia and most of South America."
