MINNEAPOLIS (LEARFIELD) – The University of Minnesota Medical School researchers today published the results from the first randomized clinical trial testing hydroxychloroquine versus a placebo for the post-exposure prevention of COVID-19.
“So what the trial showed is that hydroxychloroquine did not have a preventative effect,” said Dr. David Boulware, the study’s leader. “It was basically 12 percent of the people with hydroxychloroquine got COVID and 14 percent from the placebo group. That was not a statistical difference.”
Boulware says the study showed 40-percent of trial participants taking hydroxychloroquine developed non-serious side effects-—mainly nausea and upset stomach or diarrhea.
