overdose
A1Pronunciation
UK
- /ˈəʊvədˌəʊz/
US
- /ˈoʊvərˌdoʊs/
Description
- harmful excessive dose
- taking too much of a substance
- more than the body can handle
- dangerous amount
An overdose is not just about illegal drugs, even though many people first hear the word in that setting. It happens when someone takes too much of a substance, such as medicine, alcohol, or drugs. The basic idea is simple: the body can only handle so much, and going past that point can make a person very sick or even cause death.
You might hear about an overdose in the news when someone takes too much heroin or too many prescription painkillers. The word can also be used in a non-literal way. For example, someone might say they "overdosed on information" after getting far too much at once. In both cases, the main idea is the same: more than is safe, helpful, or easy to handle.
The word "overdose" refers to taking more of a substance, usually a drug, medicine, or alcohol, than the body can safely process. When that happens, the results can be harmful or even fatal. Although many people connect the word with illegal drugs, it can also refer to prescription medicine, over-the-counter medicine, alcohol, or even certain vitamins taken in very large amounts.
The effects of an overdose depend on the substance, but they can include slowed breathing, confusion, vomiting, loss of consciousness, seizures, and death. It is a medical emergency and needs immediate attention. For example: "The paramedics responded to reports of a possible opioid overdose," or "Doctors warned that taking too much vitamin D can be dangerous."
Beyond its literal medical meaning, "overdose" is also used in a figurative way for an excessive amount of something. You might say someone is "overdosing on information" if they are getting too much data at once, or that a movie "overdoses on special effects" when it uses so many that they become distracting.
Still, the literal meaning is serious. A real overdose can be life-threatening, and if you think someone is having one, you should call emergency services right away. The word may sometimes be used loosely in everyday speech, but its main meaning remains a dangerous amount of a substance entering the body.
