COVID-19;Chemoprophylaxis;Hydroxychloroquine;Adverse Drug Reactions;Health Care Workers INTRODUCTION An adverse drug reactions (ADRs) can be defined as "an noxious, unintended or unpleasant reaction resulting from an intervention related to the prophylactic, diagnostic, or therapeutic use of a medicinal product." [7] Recently, Indian Council of Medical Research (ICMR) has recommended the use of HCQ for the prophylaxis of COVID19 for high-risk population[8] and the Food and Drug Administration (FDA) has given emergency use authorization (EUA) for its use in the treatment of severe COVID-19 disease in hospitalized patients. [9] Even though the HCQ is used for the treatment of various medical conditions, there are concerns regarding adverse effects with its prophylactic use. [...]the aim of the present study was, therefore, to investigate adverse effects of prophylactic doses of HCQ for COVID-19 prophylaxis among health care workers (HCWs). MATERIALS AND METHODS This was a cross-sectional study carried out at a tertiary care hospital with a dedicated COVID-19 hospital after approval from the Institutional Ethics Committee.
