• A University of Minnesota study found that hydroxychloroquine did not prevent COVID-19 infection in high-risk healthcare workers, with 5.9% of the hydroxychloroquine group and 7.9% of the placebo group developing the virus.
• The NIH's ORCHID trial concluded that hydroxychloroquine provides no clinical benefit to hospitalized adults with COVID-19, with similar health status observed in both hydroxychloroquine and placebo groups after 14 days.
• Both studies reported side effects, such as nausea and upset stomach, but no increased risk of serious cardiac complications from hydroxychloroquine compared to placebo.
• These findings align with other trials, reinforcing that hydroxychloroquine is not an effective treatment for preventing or improving outcomes in COVID-19 patients.
