What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to specific channels in nerve and muscle cells of parasites, causing their paralysis and death. This makes it effective in treating infections caused by roundworms, threadworms, and other parasites. It is classified as an anthelmintic, meaning it helps expel parasitic worms from the body.
Indications / Uses
Ivermectin is primarily used for treating certain parasitic infections. The most common uses include:
- Onchocerciasis (River Blindness): An infection caused by the Onchocerca volvulus worm, characterized by severe itching and eye disease.
- Strongyloidiasis: An infection caused by the Strongyloides stercoralis worm, which can lead to a range of gastrointestinal symptoms.
- Head Lice and Scabies: Topical formulations are often used to treat infestations.
While there have been discussions regarding off-label uses, such as for viral infections, these should only be considered under strict medical supervision as evidence is not universally conclusive.
