Ivermectin is an antiparasitic medication used to treat various infections caused by parasites, including river blindness, scabies, and intestinal worms. It works by paralyzing and killing parasites, preventing them from growing and multiplying. In veterinary medicine, it is also used to treat parasites in animals. While ivermectin has been researched for other uses, it should only be taken as prescribed by a healthcare professional. Misuse or self-medication can lead to serious health risks and side effects.
