Abstract

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and its high virulence along with its variable presentation have generated a significant amount of interest within the medical community. The heterogeneous nature of the symptoms of the disease caused by SARS-CoV-2, coronavirus disease 2019 (COVID-19), ranging from being asymptomatic to severe acute respiratory distress syndrome (ARDS), has created significant interest in potential therapeutics. Given the lack of randomized controlled trials, most medications are experimental, and only anecdotal evidence is available so far regarding their efficacy. One medication that emerged as an early frontrunner as a promising therapeutic was hydroxychloroquine (HCQ), a common antimalarial and lupus drug. The adverse side effects that could result from its use did not gain much attention initially. We present the cases of two COVID-19-positive patients treated with HCQ at our institution, which showed adverse effects of the medication. While HCQ may have some therapeutic effect, it should be borne in mind that patients may experience more harm than benefit from its use.
