Antivenom



         


Antivenin (or antivenom) is used in the treatment of venomous bites. It is created by injecting a small amount of the targeted venom into an animal such as a horse, a goat, or a rabbit; the subject animal will suffer an immune response to the venom, producing antibodies against the venom's active molecule which can then be harvested from the animal's blood and used to treat envenomation in others.

Antivenins typically need to be administered as soon as possible after the venom has been injected to be effective. Since the advent of antivenins, some bites which were previously inevitably fatal have become only rarely fatal provided that the antivenin is administered soon enough.
