What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to a class of drugs known as avermectins. It works by binding to certain proteins in parasites, leading to increased cell permeability and resulting in paralysis and death of the invading organisms. This effectively treats infections by stopping the parasites from reproducing and spreading.

Ivermectin is approved for treating various parasitic infections in humans, including:
- River blindness (onchocerciasis): Caused by the Onchocerca volvulus worm, transmitted through blackfly bites.
- Strongyloidiasis: An infection by the Strongyloides stercoralis nematode often found in soil.
- Scabies: A skin infestation caused by Sarcoptes scabiei mites.
Additionally, off-label uses have been explored, but these should only be considered under the supervision of a healthcare professional.
