You will need a prescription and I can tell you a lot of the big box pharmacies are not willing to fill it if the doctor puts down Covid. I got mine from Publix early on. First you have to find a doctor that will prescribe it. Most that accept Medicare and Medicaid won't because they get persecuted by the government....in essence they can't get any reimbursement from those agencies for a period of time if they prescribe it. That is how evil our goverment is. Then once you have a prescription you'll need to find a pharmacy willing to fill it. If you have any issues I would go to the website below for other options to get a prescription.
As for treatment stratagies go to the website below for a complete regimen from initial symptoms to hospitalization. These doctors have been very successful with treating Covid and several people I know who have followed it recovered relatively quickly. The key is to get the Ivermectin going early to reduce viral loads.
