I heard one of the docs treating early outpatient home-based say that Quercetin is definitely ok for prophylactic protocols and the big advantage is you can get it OTC. He did say that if you actually get COVID & are treating it, hydroxychloroquine is what works the best - more powerful & I believe it has anti-viral benefits in addition to being an ionophore.
Unfortunately, pharmacies are practicing medicine without a license & asking for the “diagnosis” when they get a hydroxy/ivermectin prescriptions. If the diagnosis is COVID, they are refusing to fill the prescription. CVS, as a corporate policy that their pharmacies have to follow, is not filling hydroxy/ivermectin prescription & there are likely other large chains doing this as well (CVS specifically mentioned). This was talked about on Bannon’s War Room show Saturday (specifically Dr.Brian Tyson & Dr. Robert Malone).
No, they're licensed and doing their job in double checking what doctors recommend. It's a second line of defense to prevent a wrongly prescribed drug. Every State sent out info on how to deal with HCQ last Spring. The one for Missouri said they were allowed to fill scripts for HCQ but were also allowed to not fill them and were gently warned that it might be dangerous, which it isn't of course. They hold the pharmacist license and have the final say in what they dispense.
