What is this? Favipiravir have been suggested as a possible treatment for COVID-19.

In this rapid review, the authors searched for studies on the safety of favipiravir in the treatment of COVID-19. They did not restrict their searches by type or language of publication and did their search on 27 March 2020. They included 6 phase 2 and 3 studies that provided safety data for a comparison of the number of adverse events in favipiravir and control groups (4299 participants with 175 person-years-of-follow-up).

What was found: At the time of this review, the included studies showed that although a favourable safety profile was reported in some patients who received favipiravir, its effectiveness for treating COVID-19 patients was uncertain.
