What It Is and How It Works
Ivermectin is a medication that belongs to a class of drugs known as anthelmintics. It targets the nervous system of parasites, causing paralysis and eventual death. This mechanism helps the body to eliminate the parasitic infection. Technically, it binds to certain chloride channels in the nerve and muscle cells of the parasites, disrupting their normal functioning.
Indications / Uses
The primary approved use of ivermectin is for the treatment of various parasitic infections. This includes:
- Onchocerciasis: Also known as river blindness, it is caused by the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: An intestinal infection caused by the worm Strongyloides stercoralis.
- Other parasitic infections: It may also be used for other infections as advised by a healthcare professional based on specific guidelines.
Off-label uses exist but should be pursued under strict medical supervision and with a clear understanding of the current evidence supporting such practices.
