It\’s important to note that ivermectin is selective for parasites and typically does not affect humans in these mechanisms.

- Onchocerciasis (river blindness)
- Head lice
- Scabies
While there has been significant interest in ivermectin for treating COVID-19, major health organizations do not currently recommend it for this use outside of a clinical trial setting due to lack of robust evidence.
