What does antidote mean?
An antidote is a substance that counteracts the effects of a poison, toxin, or venom in the body. In medicine, antidotes are specific: naloxone reverses opioid overdose, atropine treats certain nerve-agent and pesticide poisonings, and antivenom neutralizes snake or insect venom. Because each antidote works against particular toxins, identifying the poison quickly is often critical to effective treatment. Beyond its literal medical sense, antidote is widely used figuratively to describe anything that offsets an unpleasant condition or influence — laughter might be called an antidote to gloom, or a quiet weekend an antidote to burnout. This figurative use is common in journalism, advertising, and everyday conversation, giving the word a broadly positive, restorative connotation. Derived from Greek roots via Latin, antidote shares an origin with anecdote, though the two words now mean entirely different things. Whether literal or figurative, the term always implies a corrective force against something harmful.

The word 'antidote' and 'anecdote' come from the same Greek root — one saves your life, the other just entertains you.

Etymology of antidote
The word antidote comes from the Greek antidoton, meaning 'given against', formed from anti- ('against') and didonai ('to give'). It passed into English in the early 15th century through Latin antidotum. The same Greek root also produced anecdote, which originally referred to unpublished or 'not given out' material before shifting to mean a short amusing story.
How antidote is actually used
Antidote is standard in both formal medical writing and everyday figurative use. In literal contexts it typically appears with 'for' or 'to' naming the poison; in figurative contexts it is almost always paired with 'to'. The plural is simply 'antidotes', used when referring to multiple counteracting substances or remedies.
Easily confused with antidote
An anecdote is a short, amusing story about a real incident, whereas an antidote is a substance that counteracts poison — the two words share Greek roots but have entirely different meanings.
