The prefix ac- is used to indicate which timing?

• A. After meals
• B. By mouth
• C. Before meals
• D. With meals

Answer: (C)

Timing instructions in prescriptions use Latin abbreviations, and ac- stands for ante cibum, meaning before meals. This tells you to take the medication prior to eating to optimize absorption or avoid interactions with food. It’s different from routes of administration (such as by mouth) or from terms for after meals (post cibum) or with meals (cum cibis). So ac- specifically designates taking before meals.
