What does 'PRN' stand for in prescription writing?

'PRN' is a commonly used abbreviation in prescription writing that stands for "pro re nata," a Latin term that translates to "as needed" in English. This indication is used by healthcare providers to specify that a medication should be taken only when the patient requires it, rather than on a regular schedule. This approach allows for flexibility in medication administration and ensures that patients can manage symptoms or conditions effectively based on their individual needs at any given moment.

For instance, a physician might prescribe pain relievers to be taken PRN, allowing the patient to use the medication when they experience pain, rather than taking it on a fixed schedule throughout the day. This usage aligns with the principle of patient-centered care, emphasizing the importance of tailoring medication use to the patient’s specific situation.
