An antidote is a drug, chelating substance, or a chemical that counteracts (neutralizes) the effects of another drug or a poison. There are dozens of different antidotes; however, some may only counteract one particular drug, whereas others (such as charcoal) may help reduce the toxicity of numerous drugs.
