Ivermectin is an antiparasitic agent used for the treatment of various parasitic infections, including onchocerciasis (river blindness), strongyloidiasis, and other helminthic infestations. It is also used for scabies and lice infestations. Ivermectin is approved for human use and is included in the WHO List of Essential Medicines.
