'PRN' medications are prescribed to address specific symptoms or to be taken as needed rather than on a fixed schedule. The term "PRN" comes from the Latin phrase "pro re nata," which translates to "as the situation arises" or "as needed." This allows flexibility for the patient to use the medication only when they experience particular symptoms or discomfort, such as pain, anxiety, or nausea.

This approach can help manage conditions effectively without the necessity of administering medication at regular intervals when it may not be needed. On the other hand, medications that are scheduled for regular use are meant to maintain consistent levels in the body, while over-the-counter medications and emergency-use medications have different criteria and protocols associated with their administration. Thus, the essence of PRN prescribing focuses on patient autonomy and targeted symptom management.
