Pro re nata

Pro re nata (pronounced: proh ree nah-tah), often abbreviated PRN, is a Latin term that translates to "as needed" or "as the situation arises". It is commonly used in the medical field to denote medications that are not scheduled, but are only to be taken under specific circumstances.

Etymology

The term "pro re nata" originates from Latin. "Pro" translates to "for", "re" translates to "thing" or "situation", and "nata" translates to "arise". Thus, the term literally means "for the thing arisen" or "for the situation arisen".

Usage

In medical prescriptions, PRN is used to indicate that a medication should be taken as needed, rather than on a fixed schedule. This is often used for medications intended to manage symptoms that occur sporadically, such as pain or nausea.
