What does PRN indicate in medication instructions?

• A. Taken as needed
• B. Taken on a fixed schedule
• C. Before meals
• D. After meals

Answer: (A)

PRN means you take the medication as needed—only when symptoms require it, rather than on a regular schedule. This is used for intermittent or variable symptoms, with guidelines to avoid overuse such as minimum intervals or maximum daily doses. It differs from a fixed schedule, where you take the medicine at regular times regardless of how you feel. It also isn’t about meal timing (before or after meals), which indicates when to take relative to eating rather than whether to take it for symptoms.
