An antidote is a substance that can counteract a form of poisoning. Antidotes for anticoagulants are sometimes referred to as reversal agents.

The majority of poisoning exposures can be treated without major therapeutic intervention. If therapy is indicated, it is usually in the form of gastrointestinal decontamination with activated charcoal, to prevent absorption of the toxin and the subsequent toxicity that may occur.
