What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to specific sites on parasites, causing paralysis and death. This mechanism disrupts the normal nerve and muscle function of the parasites, effectively eliminating them from the host body. While it primarily targets parasites, its interaction with human cells is minimal, making it a safe option when used as directed.
Indications / Uses
Ivermectin is approved for treating certain parasitic infections in humans, including:
- Onchocerciasis (river blindness)
- Lymphatic filariasis
- Strongyloidiasis
- Scabies
While some have considered ivermectin for other uses, such as for viral infections, these applications are not widely supported by clinical evidence and should be approached with caution. Off-label use should only be considered under the supervision of a healthcare professional.

Ivermectin is available in several forms, including oral tablets and topical creams or lotions.
