Yes that regimen works. Did you know Chlorine dioxide solution (CDS) works too. It is even cheaper than HCQ and its efficacy is as good as HCQ and safety is even safer than HCQ. HCQ is really safe. Even Wikipedia tells us that the WHO has found HCQ as one of the safest medicines.CDS is even more safe. With all the insanity go on out there, it's a good idea to have more than one plan to protect you and your family.
