What does the abbreviation "sig" mean on a prescription?

The abbreviation "sig" on a prescription is derived from the Latin word "signatura," which translates to "let it be labeled." In the context of a prescription, "sig" is used to specify the directions for the patient on how to take the medication. This includes information such as dosage, frequency, and method of administration.

The other options do not accurately capture the meaning of "sig." While "signature verification" and "signature required" relate to aspects of validating a prescription, they do not pertain to the instructions for medication use. "Signal for refills" does not accurately represent the function of "sig," as it does not provide any information regarding the administration of the prescribed medication. Understanding the term "sig" is essential for ensuring that patients receive clear and accurate instructions from their healthcare providers.
