What does PRN stand for in medication administration?

PRN stands for "pro re nata," a Latin phrase meaning "as needed" or "as the situation arises." This term is commonly used in medication administration to indicate that a medication should be given based on the patient's needs rather than on a fixed schedule. For instance, a patient might take pain medication PRN when they are experiencing discomfort, rather than taking it at specific intervals.

The concept of administering medication based on frequency does not apply to medications labeled as PRN, as these are not given according to a regular dosing schedule. Medications administered at fixed intervals are scheduled medications, while PRN medications are specifically used in response to symptoms or conditions that arise. Emergency medications have a different implication, as they are intended for acute situations rather than ongoing care, and nighttime medications are unrelated to the PRN designation. Understanding this terminology is crucial for medication aides to ensure that they administer medications appropriately and meet the needs of those in their care.
