EPO and COVID-19: Based on the known neuroprotective and anti-inflammatory features of EPO, and its proven efficacy and excellent tolerability in different neuropsychiatric conditions (Ehrenreich et al. 2020; Miskowiak et al. 2021; Sargin et al. 2010; Sirén et al. 2009), we proposed the use of recombinant human (rh) EPO for the treatment of severely affected COVID-19 patients.
