The drug ivermectin remains a flashpoint in the debate over the treatment of Covid-19. Labeled merely as a “horse de-wormer” by the Food and Drug Administration, the medication was once called a “wonder drug” and its developers won the Nobel Prize for Medicine in 2015. In spite of the FDA’s apparent campaign against ivermectin, the remedy is now the subject of a national trial which includes research being done at the University of Virginia to find out how effective the “controversial” drug is against early stages of COVID-19.
