The symbol c̅ indicates which instruction?

• A. With
• B. Before meals
• C. After meals
• D. Without

Answer: (A)

Interpretation of prescription shorthand. A bar over the letter c comes from Latin cum, meaning with. This tells the patient to take the medication with something else (often with meals or alongside another substance), rather than on an empty stomach or after meals. It is different from instructions for before meals or after meals, which use different Latin abbreviations. Therefore, the instruction conveyed is With.
