What is Ivermectin Used For?

Ivermectin is primarily used to treat infections caused by certain parasites, including:

  • Strongyloidiasis (intestinal infection)
  • Scabies

How Ivermectin Works

Ivermectin works by interfering with the nervous system and muscle function of parasites, leading to their paralysis and eventual death. It binds to glutamate-gated chloride channels in the nerve and muscle cells of parasites, increasing the permeability of the cell membrane to chloride ions. This hyperpolarizes the cells, resulting in paralysis and death of the parasite.
