Brazilian study finds ivermectin an ineffective COVID-19 treatment
March 31, 2022
The controversial drug ivermectin failed to prevent COVID-19 hospitalizations in a large clinical trial in Brazil, and a University of Minnesota study co-author instead urges people use proven therapies against the infectious disease.
While COVID-19 vaccine opponents have championed ivermectin as an alternative, the study published Wednesday in the New England Journal of Medicine, showed no significant difference in hospitalizations among 1,358 Brazilians who took the anti-parasitic drug or a nonmedicating placebo within seven days after symptoms appeared.
The results ahead of a potential COVID-19 wave in the U.S. should steer people toward approved therapies such as antiviral drugs, said Dr. David Boulware, the U's infectious disease expert who was a study co-author. "While trying a medicine, when there were no therapies available, was not unreasonable, now there are multiple effective therapies available," Boulware said.
