theres tons of “promising agent” articles made to suggest lines of research that never turned into an actual recommended treatment because, surprise, it didnt work when tested, was too insignificant in changing results, or had such severe side effects that negated any positive effect it had. find an article that actually recommends it as a treatment before touting it as one.
reading the articles: the second mentions the possibility of it being a treatment, but also notes that the required levels to have an effect are 35x higher than FDA approved levels for humans, and when absorbed by the body isn't delivered to the places that need it, which means people would require even higher dosage levels to achieve the level of ivermectin in order to have an effect. taking it as-is is like taking bleach - in testing it kills covid, so technically it'll help kill covid, but it'll also kill you before it has any effect on covid.
