Currently there is no evidence that ivermectin is helpful in either acute COVID or post COVID syndrome (long COVID). Ivermectin is not approved by the FDA for the treatment of any viral infection, including COVID-19. The safety and efficacy of ivermectin for the prevention and treatment of COVID-19 have been evaluated in clinical trials and observational cohorts.
