In March 2020, the World Health Organization announced the new COVID-19 pandemic, which represented a challenge for health services and professionals. An effective treatment against this disease has not yet been developed; as such, several drugs are used without evidence of efficacy, which in some cases may lead to unwanted events. This is a cross-sectional study with the objective of evaluating adverse drug reactions (ADRs) in patients with COVID-19, identified between March 1 and August 15, 2020, in Brazil, as well as assessing the factors associated with the emergence of severe reactions. To compare the proportions of samples related to the notifier, patient, drugs and adverse events, we used Fisher's chi-square and exact nonparametric tests; and to compare the means of the data with normal distribution, we used the Student's t-test and Mann-Whitney's test. A multivariate logistic regression analysis was also performed, estimating the crude and adjusted odds ratio (OR) by the Stata software, version 10.0. A total of 631 ADRs were identified in 402 patients. The main drugs were hydroxychloroquine (59.5%), azithromycin (9.8%) and chloroquine (5.2%). The reactions manifested primarily in the cardiac system (38.8%), gastrointestinal system (14.4%), skin tissue (12.2%) and hepatic system (8.9%). Chloroquine (OR = 5.4; 95%CI: 1.9-15.6) and hydroxychloroquine (OR = 2.1; 95CI%: 1.2-3.6) were the only drugs associated with severe ADR. Our findings provide support for better practices in pharmacovigilance, contributing to effective and secure regulatory decision-making by the Brazilian Health Regulatory Agency, patients and society as a whole.
