FDA Revokes Emergency Use of Hydroxychloroquine for COVID-19 The Food and Drug Administration <br />withdrew emergency use authorizations for hydroxychloroquine and chloroquine on Monday. The agency determined that the treatments <br />"are unlikely to produce an antiviral effect" after reviewing data from large clinical trials. The FDA had also warned <br />against the drugs as they <br />could lead to potentially <br />fatal cardiac side effects. The treatments were previously promoted <br />by President Donald Trump despite concerns <br />about their safety and effectiveness. No other treatments have <br />emerged successfully, though <br />several vaccines are in development.
