What type of medication might be prescribed based on the abbreviation "prn"?

The abbreviation "prn" stands for "pro re nata," which is Latin for "as needed." This terminology is commonly used in medication prescriptions to indicate that the medication should only be taken when necessary, rather than on a fixed schedule. For example, a patient may be prescribed pain medication to be taken prn for pain or discomfort rather than at set times throughout the day. This allows for flexibility and individual assessment of the patient's needs.

In contrast, scheduled medications are taken at regular intervals, long-term medications are prescribed for ongoing treatment over a long duration, and preventative medications are taken to prevent certain conditions or diseases rather than to alleviate symptoms as they arise. Therefore, the understanding of "prn" directly relates to the appropriateness of prescribing medication based on individual need rather than a strict regimen.
