What It Is and How It Works
Ivermectin is classified as an antiparasitic medication. Its primary mechanism involves disrupting nerve and muscle functions in parasites, effectively paralyzing and eventually killing them.

- Strongyloidiasis (threadworm)
- Head lice and scabies (when in topical form)
While ivermectin has been studied for various other conditions, including off-label uses, its effectiveness and safety for these purposes remain under investigation. Use for any condition other than approved parasitic infections should only occur under strict medical supervision.
