What is the meaning of "prn" in a medication context?

In a medication context, "prn" stands for "pro re nata," a Latin phrase that translates to "as needed." This term is used to indicate that a medication should be administered only when the patient requires it rather than on a fixed schedule. For example, a pain relief medication may be prescribed to be taken prn, meaning the patient can take it when they are experiencing pain rather than at specific times each day.

Understanding this term is crucial for medication aides as it affects how and when they dispense medication. They must assess the patient's condition and provide the medication in response to the patient's reported symptoms rather than adhering to a strict dosage timeline. This flexibility allows for patient-centered care, ensuring that the patient's needs are met more effectively.
