What It Is and How It Works
Ivermectin is an anti-parasitic medication discovered in the 1970s. It works by binding to specific gabaergic and glutamate-gated chloride channel proteins of the parasite, leading to paralysis and death of the parasite.
In more technical terms, ivermectin increases the permeability of the cell membrane to chloride ions, resulting in muscle paralysis and death of the parasite.

- Intestinal strongyloidiasis

- Some off-label uses include rosacea and head lice in children (under certain guidelines)
Its potential use in cancer is still under investigation and remains experimental. Patients considering this must discuss it thoroughly with a healthcare provider.
