What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the class of medicines known as avermectins. Its primary mechanism of action is binding to specific chloride ion channels in the nerves and muscle cells of parasites. This causes increased permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite.

The main approved uses of ivermectin in humans include the treatment of:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.

Some off-label uses, though widely discussed, are less supported by clinical evidence and health authority approvals.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in oral tablet form for human use.
