evidence: But the regulator stressed the lifting of the ban did not amount to an endorsement of off-label prescribing of ivermectin to treat Covid-19, citing studies showing it was not an effective treatment. "A large number of clinical studies have demonstrated ivermectin does not improve outcomes in patients with Covid-19. The National Covid Evidence Taskforce (NCET) and many similar bodies around the world, including the World Health Organization, strongly advises against the use of ivermectin for the prevention or treatment of Covid-19." At the time of the ban, off-label prescriptions of ivermectin for Covid-19 were being discussed quietly in Facebook and Telegram communities, with people sharing the names of sympathetic doctors who were willing to prescribe it. The TGA said at the time it was concerned that people could be taking unsafe doses of the drug if following advice from social media.
