An overdose can be accidental or intentional and can lead to severe health consequences, including death. It's a critical medical emergency.

The story behind the word. The word 'overdose' is a straightforward compound of the English prefix 'over-' meaning 'too much, excessive' and 'dose,' which comes from the Greek dosis, meaning 'a giving, a portion prescribed.' So, an 'overdose' is literally 'too much of a prescribed portion' or 'an excessive giving' of a drug. This clear etymology directly points to the dangerous quantity of a substance.
