Which abbreviation represents a suppository?

• A. supp.
• B. syr.
• C. tab.
• D. NS

Answer: (A)

Abbreviations for dosage forms tell you how a medicine is given. A suppository is a solid form inserted into the rectum or vagina that melts at body temperature to release the drug. The abbreviation for this form is supp., so it clearly designates a suppository. The other options refer to different forms or items: syr. is typically syrup (an oral liquid) or occasionally a syringe in other contexts, tab. is a tablet (an oral solid), and NS stands for normal saline (a solution, not a dosage form for a drug). Thus, supp. is the correct shorthand for a suppository.
