What It Is and How It Works
Ivermectin is an antiparasitic medication that affects a specific type of chloride channel found in the nerve and muscle cells of parasites. By binding to these channels, ivermectin increases the permeability of the cell membrane, leading to paralysis and death of the parasite. This mechanism effectively clears many types of parasitic infections from the body.

- Intestinal strongyloidiasis
- Onchocerciasis (river blindness)

Off-label, ivermectin has been investigated for other potential uses, but these applications should only be pursued under professional supervision as evidence may be limited or controversial.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
