The FDA reports:
July 1, 2020 Update: "A summary of the FDA review of safety issues with the use of hydroxychloroquine and chloroquine to treat hospitalized patients with COVID-19 is now available. This includes reports of serious heart rhythm problems and other safety issues, including blood and lymph system disorders, kidney injuries, and liver problems and failure.
June 15, 2020 Update: Based on ongoing analysis and emerging scientific data, FDA has revoked the emergency use authorization (EUA) to use hydroxychloroquine and chloroquine to treat COVID-19 in certain hospitalized patients when a clinical trial is unavailable or participation is not feasible. We made this determination based on recent results from a large, randomized clinical trial in hospitalized patients that found these medicines showed no benefit for decreasing the likelihood of death or speeding recovery. This outcome was consistent with other new data, including those showing the suggested dosing for these medicines are unlikely to kill or inhibit the virus that causes COVID-19. As a result, we determined that the legal criteria for the EUA are no longer met. Please refer to the Revocation of the EUA Letter and FAQs on the Revocation of the EUA for Hydroxychloroquine Sulfate and Chloroquine Phosphate for more information."
The National Institute of Health (The NIH) ended it study of hydroxychloroquine concluding it provided no benefit in treating Covid-19:
"A clinical trial to evaluate the safety and effectiveness of hydroxychloroquine for the treatment of adults hospitalized with coronavirus disease 2019 (COVID-19) has been stopped by the National Institutes of Health. A data and safety monitoring board (DSMB) met late Friday and determined that while there was no harm, the study drug was very unlikely to be beneficial to hospitalized patients with COVID-19. After its fourth interim analysis the DSMB, which regularly monitors the trial, recommended to the National Heart, Lung, and Blood Institute (NHLBI), part of NIH, to stop the study. NHLBI halted the trial immediately.
The Outcomes Related to COVID-19 treated with hydroxychloroquine among In-patients with symptomatic Disease study, or ORCHID Study, was being conducted by the Prevention and Early Treatment of Acute Lung Injury (PETAL) Clinical Trials Network of NHLBI. The data from this study indicate that this drug provided no additional benefit compared to placebo control for the treatment of COVID-19 in hospitalized patients."
The distracting noise around hydroxycholorquine serves only to give a panicky public false hope. The drug must be administered in a hospital setting, in tightly managed doses, to monitor its potentially devastating side-effects. All that for no benefit in treating Covid, as found by the NIH.
The Washington Post reported:
"Scientists have since pointed to major flaws in those original studies and say there is a lack of reliable data on the drugs. Experts warn about the dangerous consequences of over-promoting a drug with unknown efficacy: Shortages of hydroxychloroquine have already occurred, depriving lupus and rheumatoid arthritis patients of access to it. Doctors say some patients could die of side effects. Other potential treatments for covid-19 could get overlooked with so much concentration on one option."
