I beg your pardon? Since when have HCQ and ivermectin been used to treat the flu? What drugs actually ARE used to treat the flu? Oseltamivir (Tamiflu), zanamivir (Relenza), peramivir (Rapivab) or baloxavir (Xofluza). https://www.mayoclinic.org/diseases-conditions/flu/diagnosis-treatment/drc-20351725 You should consider getting a new doctor. Yours sounds dangerous.
