Ivermectin is an antiparasitic drug used to treat a variety of different parasites and infections in humans and animals. It works by paralyzing the parasites and disrupting their normal bodily functions. This causes them to die off and eventually leave the body.
However, it's important to note that ivermectin does not immediately kill the parasites. Rather, it takes some time for it to take full effect, which is why it's important to know how soon you can eat after taking it.
