Antivenom is a medical treatment used to counteract the effects of venom from bites or stings of poisonous animals, such as snakes, spiders, and scorpions. It is made by immunizing animals, often horses or sheep, with small amounts of venom, allowing their immune systems to produce antibodies. These antibodies are then collected, purified, and formulated into a serum that can be administered to humans. When a person is bitten or stung, antivenom can help neutralize the venom, reducing symptoms and preventing serious complications. It is crucial to receive antivenom as soon as possible after a venomous bite or sting to improve the chances of recovery and minimize potential damage to the body.
