Abstract
Objective: to assess effectiveness and safety of hydroxychloroquine and chloroquine on the treatment of COVID-19. Study desing: a systematic review of literature was performed in two databases; studies were included if they had as intervention use of chloroquine or hydroxychloroquine and reported outcomes on laboratorial or clinical findings or description of side effects. Results: 38 studies were included; of those, only one fulfilled inclusion criteria and were included in this review. This study has important methodological issues and only reported viral load, but any clinical outcomes. Conclusions: Many ongoing clinical trials will provide new evidences about the use of hydroxychloroquine and chloroquine to the treatment of COVID-19. Current evidence do not support its use on clinical practice.
