Antivenom vs. Antidote: What's the Difference?

By Janet White & Aimie Carlson || Updated on May 24, 2024
Antivenom is a treatment specifically for venomous bites or stings, while antidote is a broader term for any substance that counteracts poison or toxin effects.

Key Differences

Antivenom is a biological product used to treat venomous bites or stings from animals such as snakes, spiders, or scorpions. It is created by injecting a small amount of venom into an animal, then harvesting and purifying the antibodies produced. An antidote, on the other hand, is a substance that counteracts the effects of poisons or toxins in the body. Antidotes can be chemical compounds, medications, or other substances designed to neutralize, prevent absorption, or counteract the toxic effects.
Antivenom is used in medical settings where specific envenomation occurs, like snake bites or spider stings. It targets the toxins directly, neutralizing their harmful effects. Antidotes are used in various scenarios, from drug overdoses to chemical poisonings, and work through different mechanisms, such as binding to the toxin, blocking its effects, or accelerating its removal from the body.
While antivenom must be matched to the specific type of venom, an antidote can be more versatile, sometimes effective against multiple toxins. For instance, activated charcoal can act as an antidote by adsorbing a variety of ingested poisons, preventing their absorption.
Antivenom is often produced through a complex process involving animals and is specific to certain species' venom. Antidotes, however, can be synthetic or derived from various natural or chemical sources and are not as species-specific.
