[…] All studies assessing the use of favipiravir in humans by 27 March 2020 were considered for inclusion. […] Twenty-nine studies were identified as potential sources of evidence of the clinical safety of favipiravir. […] The proportions of grade 1-4 AEs on favipiravir was 28.2% vs 28.4% (P = n.s.) in the comparison arms. […] The proportion of discontinuations due to AEs on favipiravir was 1.1% vs 1.2% (P = n.s.) in the comparison arms. […] There were significantly fewer gastrointestinal AEs occurring on favipiravir vs comparators [8.7% vs 11.5%; P = 0.003]. […] Favipiravir showed significantly more uric acid elevations than comparators [5.8% vs 1.3%; P<0.0001]. […] Favipiravir demonstrates a favourable safety profile regarding total and serious AEs. […] Favipiravir may be safe and tolerable in short-term use, but more evidence is needed to assess the longer-term effects of treatment. […] Given the limitations of the evidence and unresolved safety concerns, caution is warranted in the widespread use of favipiravir against pandemic COVID-19.

[…] Favipiravir is an anti-viral agent that selectively and potently inhibits the RNA-dependent RNA polymerase, it has been used for treatment of some life-threatening infections such as Ebola virus, Lassa virus and rabies. […] Favipiravir group (experimental): Favipiravir 1600mg each dose, twice a day on the 1st day; 600mg each dose, twice a day from the 2nd to the 7th day, Oral administration, the maximum number of days taken will be no more than 14 days plus routine treatment for COVID-19.

32536670 In light of the recent pandemic, favipiravir (Avigan®), a purine nucleic acid analog and antiviral agent approved for use in influenza in Japan, is being studied for the treatment of coronavirus disease 2019 (COVID-19). […] Increase in blood uric acid level is a frequent side effect of favipiravir. […] Here, we discussed the mechanism of blood uric acid elevation during favipiravir treatment. […] Favipiravir is metabolized to an inactive metabolite M1 by aldehyde oxidase and xanthine oxidase, and excreted into urine. […] Favipiravir and M1 act as moderate inhibitors of organic anion transporter 1 and 3 (OAT1 and OAT3), which are involved in uric acid excretion in the kidney. […] Thus, favipiravir is thought to decrease uric acid excretion into urine, resulting in elevation of uric acid levels in blood. […] Elevated uric acid levels were returned to normal after discontinuation of favipiravir, and favipiravir is not used for long periods of time for the treatment of viral infection. […] Nevertheless, the adverse effect of favipiravir might be clinically important in patients with a history of gout, hyperuricemia, kidney function impairment (in which blood concentration of M1 increases), and where there is concomitant use of other drugs affecting blood uric acid elevation.
