Multiple studies provide data that hydroxychloroquine (brand name: Plaquenil) does not provide a medical benefit for hospitalized patients with COVID-19. Due to similarities in the safety profile between hydroxychloroquine and chloroquine, and between azithromycin and the other macrolides authorised in the UK (clarithromycin and erythromycin), available data for these medicines were also included in the review to understand if there were likely to be similar risks associated with chloroquine and with the other macrolide antibiotics.
