A recent analysis conducted by French researchers suggests that nearly 17,000 people across six countries may have died after taking hydroxychloroquine (HCQ) during the initial wave of
COVID-19 in 2020. Hydroxychloroquine, an anti-malaria drug, was prescribed off-label to treat COVID-19 in the early stages of the pandemic, as researchers and physicians sought potential treatments for the disease. Additionally, it was proposed as a preventative measure. On March 28, 2020, the Food and Drug Administration (FDA) granted emergency use authorization for the drug and initiated clinical trials.
