How are PRN medications typically defined?

PRN medications are defined as "as needed." This designation indicates that these medications are prescribed to be taken only when a specific condition arises or symptoms are present, rather than on a regular or fixed schedule. For example, a patient might be prescribed pain relief medication to be taken as needed for episodes of pain rather than at predetermined intervals. This flexibility allows individuals to manage their symptoms proactively, taking medication only when the severity of their symptoms warrants it.

Routines or scheduled medications, like those taken daily or on a fixed basis, differ significantly from the PRN approach. Daily scheduled medications are often intended for ongoing management of a condition, while PRN medications empower patients to initiate treatment based on their current needs, thus providing a tailored approach to symptom management.
