What does PRN stand for?

• A. Immediately
• B. As needed
• C. Daily
• D. Twice daily

Answer: (B)

PRN means pro re nata, a Latin phrase that translates to “as needed.” This instruction tells you to take the medication only when you have symptoms that require it, not on a fixed schedule. It’s used for medicines that are meant to relieve intermittent or as-occuring symptoms, like pain or nausea. For example, you’d use a PRN pain reliever when pain is present, and skip doses when you’re symptom-free. Remember to follow the overall safety rules—don’t exceed the prescribed total daily amount, and if symptoms persist or worsen, contact a clinician. Choices like “immediately,” “daily,” or “twice daily” describe fixed timing, not an as-needed approach.
