The article suggests that the FDA has approved ivermectin as a COVID treatment, which is absolutely false.

A judge ruled that the FDA cannot interfere with the authority of a physician to prescribe medication to a patient. They could be prescribing aspirin to treat COVID, and the ruling would still apply.

You seem to be right about that the FDA does not yet recommend it as a treatment. However large studies do suggest its effectiveness like for example the study here: https://www.cureus.com/articles/111851-regular-use-of-iverme...

You should immediately be suspect of any “study” that random ass just throws half the people out of it. It’s clear that this was a “fudge the numbers” scenario

In fact, I cannot find a double blind that supports the use of ivermectin to treat Covid.

I have several issues with that study, starting with the fact that they left out 63% of the participants for no clear reason, which is even more damning given the fact that the cohort controlled by the authors themselves. Furthermore, their positive results are based on 280 individuals, not the initial sample.
