What is the abbreviation for after meals?

• A. a.c.
• B. ad lib
• C. p.o
• D. p.c.

Answer: (D)

Understanding prescription timing hinges on Latin meal-related abbreviations. After meals is described as post cibum, abbreviated pc (often written as p.c.). That is why the correct instruction for taking a dose after meals uses pc. In contrast, ante cibum (a.c.) means before meals; per os (p.o.) means by mouth regardless of meal timing; ad libitum means as desired, not tied to meals. So pc accurately communicates “after meals.”
