While randomized trials are certainly the gold-standard for determining if you should give a new drug to treat an arbitrary disease, that process is far too conservative during a pandemic where a huge majority of the world cannot access proper medical care. Ivermectin is already massively produced, used throughout the world, and cheap to manufacture (compared to new anti-Covid drugs). Even months ago before the benefits were known, the risks of taking the drug were very small, especially when the treatment guidelines were to do practically nothing.
Still, the many pieces of non-randomized evidence can still clearly point towards this drugs efficacy. The sudden drop in Covid cases in India as the clearest indicator to me.
