What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to components within the parasites, causing paralysis and death. This action prevents the parasites from thriving and multiplying, effectively eradicating the infection.
On a technical level, ivermectin increases the permeability of cell membranes to chloride ions, which disrupts nerve and muscle function in the parasites. While it does not cure symptoms like itching or nodules immediately, it helps reduce the parasitic load over time.

Ivermectin is primarily used for the treatment of:
- Onchocerciasis (river blindness)

Off-label uses have emerged but remain contentious and should only be considered under medical supervision.
