What does the letter "C" indicate in medical prescriptions?

In medical prescriptions, the letter "C" is commonly used to signify "with." This abbreviation originates from the Latin word "cum," which translates to "with" in English. It is important for deciphering prescriptions and understanding medication instructions, as it helps to clarify the relationship between different components of the prescription, such as the quantity of medication and whether it should be taken alongside food or other substances.

The other options do not accurately represent common meanings of the letter "C" in a medical context. For instance, "capsule" typically would not be abbreviated with just a "C," and "clear" or "concentrated" are not standard uses for that particular letter in medical prescriptions. Understanding these abbreviations is crucial for accurately interpreting prescriptions and ensuring safe medication administration.
