The abbreviation used for 'with' in prescription writing is represented by the letter 'c.' This abbreviation comes from the Latin word "cum," which means "with." In medical and pharmaceutical contexts, shorthand is commonly used to convey instructions quickly and efficiently, and 'c' serves this purpose effectively when indicating that a medication should be taken with something else, such as food or another medication.

Other options represent different terms: 's' is often used for 'without,' 'gtt' stands for 'drops' in reference to liquid medication, and 'R' usually designates 'right' when indicating directions in prescriptions. Therefore, 'c' distinctly identifies the concept of 'with,' making it the correct abbreviation in this context.
