What does PRN medication refer to?

PRN medication refers to medications that are taken "as needed." This means that the medication is not taken on a regular schedule but rather in response to specific symptoms or situations that arise. For instance, a patient may be prescribed pain relief medication to take PRN, indicating that they should take it only when they experience pain rather than at set intervals. This approach allows for a flexible treatment plan tailored to the patient's individual needs and can help minimize unnecessary medication usage when symptoms are not present.

In contrast, other options involve medications with different administration protocols or requirements, such as those that are scheduled or required to be taken daily, which do not fit the definition of PRN.
