The challenge is that you don’t necessary want to be often taking lots of drugs “just in case,” since they can have their own long-term issues (just browse the other comments here for discussion). Also, adverse-drug interactions is potentially a a major killer already in the US, sometimes from doctors making mistakes, and often from people using OTC drugs outside of their safe regime. So then, we might wait until it is clear that intervention is necessary, but now the intervention also probably needs to be much more aggressive. And besides, we do have a pretty good preventative/protective option already in vaccines. It is only when breakthrough cases lead to hospitalization that we then need to pull out the backup strategies, otherwise, we’ve seen that statistically our primed immune systems are usually pretty good at dealing with it on their own.
