Definition

Latin abbreviation for 'pro re nata' (as needed), indicating medication should be taken when necessary rather than on a fixed schedule—basically healthcare's version of 'your call.'

Example Usage

The doctor prescribed pain medication PRN, trusting I wouldn't abuse the privilege and treat it like an all-you-can-eat buffet.

Origin

From Latin 'pro re nata,' meaning 'for the thing born' or 'as the circumstance arises'

Fun Fact

PRN orders are both a blessing and a curse for nurses, who must constantly judge whether patients actually need that medication right now or are just bored.
