COVID is brand new. No one know what really works and what doesn’t. We’re all working off our best judgement. For some doctors that’s “try everything that might work”, for others it’s “try only things that could most likely work”, and for others it’s “don’t try anything unless we know it works”. Those are all valid and rational approaches to something like this, and there are no wrong answers. The important thing is for the doctor and the patient to agree on the overall plan.
