Z-pak is to stop infection in the lungs.
Zinc is also a critical part, I believe. (Also harmless.)
Here is a good story: https://abc7.com/health/la-doctor-seeing-success-with-hydroxychloroquine-to-treat-covid-19/6079864/
“Every patient I’ve prescribed it to has been very, very ill and within 8 to 12 hours, they were basically symptom-free,” Cardillo told Eyewitness News. “So clinically I am seeing a resolution.”
FYI, street prices (before Covid) for HCQ was $40 for 50 pills. Z-Paks are $15. Zinc is $20.
Can get a bottle of the zinc 222 anywhere on the internet for around $15. Lots in stock as of yesterday. No prescription needed.
