What It Is and How It Works
Ivermectin is an antiparasitic medicine belonging to the avermectin class. It primarily works by binding to parts of the parasite\’s nerve and muscle cells, leading to paralysis and death of the parasite. This mechanism allows it to be effective against a variety of parasitic infections, which makes it useful in managing conditions like onchocerciasis and strongyloidiasis.
Indications / Uses
Ivermectin is approved for use in treating several parasitic infections. These include:
- Onchocerciasis: Also known as river blindness, it is caused by the Onchocerca volvulus parasite.
- Strongyloidiasis: An infection caused by the Strongyloides stercoralis parasite.
- Scabies and Lice Infestations: While topically used, oral ivermectin can be prescribed in certain cases.
It\’s important to note that off-label use, such as the use for viral infections, should be avoided unless specifically recommended by a healthcare provider.
