To the Editor — In March 2020, in the midst of the COVID-19 pandemic1, reports that chloroquine (CQ) can inhibit the growth of severe acute respiratory syndrome coronavirus (SARS-CoV-2)2,3 have brought this molecule into the spotlight. Hydroxychloroquine (HCQS), which is typically used in dermatology clinics for the management of systemic lupus erythematosus (SLE) and has a better clinical safety profile and fewer drug–drug interactions than CQ, has also been demonstrated to have anti-SARS-CoV activity in vitro2,4. Now, amid the speculation regarding the beneficial roles of these molecules in COVID-19 treatment, shortages of CQ and HCQS are feared.
