"Recently there's been a lot of talk about ivermectin for it as well."

Yes. In our research, we found this listed as "Plan B" (my words), if you could not get access to HCQ. HCQ has been "blacklisted" in many places and is harder to get. While Ivermectin supposedly has easier access and it does have benefit.

I don't know, as we found an "underground" way to get HCQ and is shown to be better.
