What does nauseant mean?

Nauseant means producing nausea—a feeling of sickness in your stomach, as if you might vomit.

People can experience nausea from food that has upset their stomach, from the side effects of medications, or from a number of other conditions that affect the stomach, such as seasickness, motion sickness, morning sickness, carsickness, and anxiety. The word nauseating is much more commonly used to describe such things.

Nauseant, on the other hand, is typically used in a medical context, such as to describe a medication or treatment that has nausea as a known side effect.

The word nauseant can also be as a noun in this context to refer to such medications or to other things that can cause nausea.

The word antinauseant can be used as a noun to refer to things like medications or other substances that are intended to relieve nausea, or as an adjective to describe such things.

Example: The patient has gastrointestinal issues, so I avoided prescribing any nauseants.

Where does nauseant come from?

The first records of the word nauseant come from the 1800s. It is ultimately thought to derive from the Greek nausíā, meaning “seasickness,” from naûs, meaning “ship” (the same root is the basis of the word nautical). The suffix -ant is used to form adjectives and nouns.

Nausea can be caused by very different things, including bad food, inner ear problems, and stress. However, describing something as nauseant or calling something a nauseant is almost always done in a medical context. Antinauseants are used to help people avoid nausea, such as during chemotherapy treatments.
