What It Is and How It Works
Ivermectin is primarily used to treat a range of parasitic infections. It works by interfering with the nerve and muscle functions of parasites, causing paralysis and death.

- Lymphatic filariasis: Affects the lymph system and is caused by thread-like worms.
- Strongyloidiasis: An intestinal infection caused by the Strongyloides stercoralis worm.
- Scabies and lice: Common infestations treated with topical ivermectin formulations.
Off-label uses of ivermectin include the controversial and unapproved potential treatment of COVID-19, which should only occur under strict clinical supervision due to mixed evidence regarding its efficacy.
