Few times a week of maintenance doses of Ivermectin should prevent parasites.
100% ... I enjoy a bit of delicious apple-flavored horse paste 3x per week, and I'm thinking of working fenben into the rotation.
Not only does it destroy parasites, it also helps fight cancer, probably because as Rife suggested, cancers are microbial in nature, and very likely micro- / intra-cellular parasites. I wouldn't be surprised if many neurodegenerative diseases such as CJD or Mad Cow, as well as alzheimer's/parkinson's are somehow related to micro-parasites that cross the blood-brain barrier. Give how iver and fenben destroy cancers, that's my working hypothesis.
And, in terms of safety, I'll second your objection. It's taken on a daily basis almost like candy in Africa to prevent the myriad parasitic diseases that run rampant therre, from malaria to that river blindness thing ... and its safety profile is incredibly high. It's only recent COVID propaganda that got people bogusly questioning its safety, despite its constant use for decades with very little adverse effects, only good effects.

So, yes, we've heard "safe and effective" abused lately, but these earlier statements were made as the result of real studies (cited in the article) absent any political agenda, and for little financial motive, since it's cheaper than dirt to produce.
