Ivermectin is a multifaceted drug that won the Nobel prize for medicine in 2015.

Ivermectin is first and foremost used in humans as an ant parasitic treatment. "Ivermectin is approved for use in humans to treat intestinal strongyloidiasis and onchocerciasis."

There is zero evidence that Joe Rogan used horse paste with Ivermectin rather than a prescription for IVM pills. The fact that he is a multi-millionaire and able to get the best doctors available, makes the claim laughable.

There is ivermectin for animals and ivermectin for people. Joe Rogan has not suggested taking the animal version of ivermectin.
