What It Is and How It Works
Ivermectin is an antiparasitic medication originally derived from the bacterium Streptomyces avermitilis. It functions by binding to certain ion channels in the nerve and muscle cells of parasites, causing paralysis and death of the parasite. This action effectively clears parasitic infections in humans and animals.

- Intestinal Strongyloidiasis: Infection by the intestinal threadworm Strongyloides stercoralis.
Though some reports suggest off-label uses for conditions like COVID-19, it’s critical to note these uses should only be pursued under professional medical supervision due to varying evidence on efficacy and safety.

Ivermectin is available in various forms including:
- Oral Tablets: The most common form for human use.
