It sounds like you have roughly half the information bud so I will help with the rest of the story.
Everything was off label for Covid-19 until the FDA approved Remdisavir and about 10 others on October 22nd 2020. There are a metric s**t ton of meds that are used off label to treat various diseases but it is up to the Dr's and hospitals to decide that not the Pharma's. Pfizer and J&J paid those fines for trying to repurpose drugs for other uses (Pfizer even tried to change the name of BEXTRA if memory serves) that were already pulled off the market by the FDA because they were proven unsafe for human consumption
despite Pfizer and J&J falsifying the data showing they were initally safe. Also part of that lawsuit was both Pharma's illegally giving kickbacks to doctors and hospitals to incentivize promoting it. So when they say "safe and effective" I see a red flag. Most people just blindly "trust the science" but science can, and is manipulated to deliver whatever end results the one paying wants my friend. It isn't a new thing, Asbestos, lead paint, RoundUp and Parquat are a few, J&J knew back in the 70's that baby powder contained Asbestos and in the 90's knew that it was harming humans but kept that almighty dollar going by hiding the data. Ever wonder why in the last few years roughly half your commercials on TV are new drugs? I do.
I am assuming you do know that Ivermectin was FDA approved for use in humans in 1987 and is currently being successfully used to fight Covid in India and Argentina? When taken in proper doses historically it has decades of use in humans and proven safer than Aspirin. Ivermectin is also boasted by the NIH as a "wonder drug" with many uses and Dr. William C. Campbell and Satoshi Omura won a nobel peace prize for using it to combat Malaria in 2015.
Here the NIH sponsors it:
Discovered in the late-1970s, the pioneering drug ivermectin, a dihydro derivative of avermectin—originating solely from a single microorganism isolated at the Kitasato Intitute, Tokyo, Japan from Japanese soil—has had an immeasurably ...
