What It Is and How It Works
Ivermectin is an anthelmintic medication, which means it is used to treat infections caused by parasitic worms. It works by interfering with the parasites\‘ nervous system, leading to paralysis and death of the parasite. This action is selective for parasites as it binds with high affinity to specific ion channels that are only present in invertebrates.
Indications / Uses
Ivermectin is FDA-approved for the treatment of several parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Scabies
- Certain species of lice
It has been investigated for off-label uses, often driven by hypothesis rather than conclusive evidence, such as for COVID-19. However, it should only be used for such purposes under the guidance of a healthcare professional.

Ivermectin is available in several formulations, including oral tablets and topical lotions. The typical oral dosing depends on the condition being treated, and adjustments may be necessary for those with liver problems, young children, or older adults.
