Systemic corticosteroids are strongly recommended for patients by WHO. I see from here https://www.indiatoday.in/coronavirus-outbreak/story/remdesi... that also budesonide is recommended for patients with mild symptoms and the usage of is backed up by recent studies.

I do not think that the problem is steroid usage by itself but depressing lack of even basic hygiene even in hospitals.

PS. Blood thinning is standard procedure in COVID-19 care for many hospitals, dunno how reasonable at home without any tests. Remdesivir is injected, I do not believe that it is distributed. Perhaps you meant ivermectin?
