What does "PRN" stand for in medication administration?

"PRN" stands for "Pro re nata," which is a Latin phrase meaning "as needed." In the context of medication administration, this term indicates that a medication can be given at the discretion of the caregiver or patient when it is deemed necessary, rather than at scheduled intervals.

For instance, a patient may be prescribed pain medication to take PRN, meaning they should take it only when they feel pain rather than on a regular schedule. This flexibility allows for more appropriate and responsive care tailored to the patient's individual needs at any moment. Understanding this concept is vital for healthcare providers, as it ensures that medications are administered in a manner that aligns with patient comfort and clinical judgment, promoting effective pain management and overall care.
