What It Is and How It Works
Ivermectin is classified as an antiparasitic medication. It works by binding to parts of the parasite\’s nerve and muscle cells, causing paralysis and eventual death. By doing this, ivermectin prevents parasites from multiplying and spreading. This mechanism makes it effective against a range of parasitic infections, both internal and external.
Indications / Uses
In medical practice, ivermectin is primarily approved for the treatment of specific parasitic infections. These include onchocerciasis (river blindness), intestinal strongyloidiasis, and certain cases of scabies. It is also used off-label in some cases for treating head lice and other parasitic conditions, though such use should only occur under professional supervision.
Due to recent interest, there have been discussions around off-label use of ivermectin for conditions such as COVID-19. However, authoritative health organizations have urged caution and recommend it only under research settings or clinical trials for this purpose.
