Ivermectin is widely used in both human and veterinary medicine to treat parasitic infections. In humans, it is primarily employed to combat diseases caused by parasitic worms, such as onchocerciasis (river blindness) and lymphatic filariasis. It works by paralyzing and killing the parasites, effectively reducing the spread of these debilitating conditions. In veterinary applications, it is commonly used to control internal and external parasites in livestock, pets, and other animals, improving their health and productivity. Additionally, Ivermectin has been explored for its potential antiviral properties, though its efficacy in this area remains under investigation and is not yet widely accepted.
