NIH's homicidal guidelines include only dexamethasone and remdesivir as therapeutics for COVID-19, with no recommendations for the most important early outpatient stage:

So CYA doctors that care more about their licenses than they do their patients, and want to stay within the bounds of the "standard of care" are left with little. A recently ended WHO study found remdesivir does not reduce patient mortality or even reduce hospital stay, so according to that study, comparatively worthless. Dexamethasone has been shown to reduce inflammation in the later stages of the disease, but if prescribed too early will actually set the patient back. If corticosteroids are started too early they "....decrease your immune response and allow for increased viral replication....." (31:40 minute mark).
