Antivenom, also known as antivenin or antivenene, is a medication used to treat venomous bites or stings from animals such as snakes, spiders, scorpions, and other poisonous creatures. Antivenoms are created by injecting small amounts of venom into animals, usually horses, and then extracting the antibodies produced in response to the venom. These antibodies are purified and used to create a serum that can neutralize the toxins in the venom when injected into a bitten or stung individual. Antivenoms are crucial in preventing serious complications and deaths from envenomation, and ongoing research is focused on improving their efficacy, safety, and availability for treating a wide range of venomous species around the world.
