Plenty of medicines are used for multiple things. Just because something is labeled X, doesn't preclude it from also being effective at Y. I'm not claiming that ivermectin is effective or not, but there is an incentive in preventing any FDA approved treatments from being used against COVID: emergency authorizations (including the current "full", "non-emergency" authorization that is contengent on the completion of ~12 additional detailed studies over the next 3 years) are only allowed by law if no FDA approved medicine is available as an alternative treatment. The fact that other, still experimental medications and vaccinations are allowed is proof that the FDA doesn't consider the current "non-emergency" vaccine authorization to be a "fully" authorized one. The full authorization of any new or existing medication would preclude all other experimental treatments from being used under emergency authorization.
