What does the abbreviation "PRN" mean?

The abbreviation "PRN" stands for "as needed" in medical terminology. It is commonly used in prescriptions or treatment plans to indicate that a medication or intervention should be administered only when necessary, rather than at scheduled intervals. This allows for flexibility in care, enabling patients to receive treatment based on their specific symptoms or needs at a given time. For example, a patient may be prescribed a pain reliever PRN, meaning they should take it when they feel pain rather than adhering to a strict dosing schedule.

In clinical practice, understanding the significance of "PRN" helps healthcare providers tailor treatments to individual patients, ensuring they receive optimal care based on their conditions.
