This episode is all about ivermectin - which truly is a wonder drug! A veritable miracle cure.
For, ahem, river blindness. And for some other parasitic diseases, like hookworm. Mostly in animals.
But in the US, you have likely heard of ivermectin not as a treatment for parasites but for different purposes altogether. There are thousands of videos on YouTube and Instagram extolling ivermectin for viral diseases like Covid, various cancers, and for something called a “parasitic detox,” or a “parasitic cleanse.”
Really? This one drug does all that?
No. It does not.
In this episode of Drug Story, we tell the tale of ivermectin, and what gets all those people on TikTok raving about this drug - what they hope it could be, what they believe it works on.
And then, with an open mind, we go to the science – to tease apart the true miracles from the mere fantasies.
