What does PRN mean in medication administration?

PRN is an abbreviation derived from the Latin phrase "pro re nata," which translates to "as needed." In the context of medication administration, this term is used to indicate that a medication should be given only when a patient requires it rather than at regular intervals. For example, a patient might be prescribed a pain reliever to take PRN, meaning they should take it only when they are experiencing pain, rather than on a fixed schedule. This approach allows for more personalized care, as it takes into account the varying needs and circumstances of the patient. The flexibility of PRN administration can enhance patient comfort and improve the overall management of their condition.
