What is the meaning of "Sig" in a prescription?

"Sig" is an abbreviation for the Latin term "signa," which translates to "label" or "sign" in English. In the context of a prescription, it refers specifically to the directions provided for the patient regarding how to take their medication. These directions typically include important information such as dosage, frequency, and any specific instructions on how the medication should be administered. The purpose of including "Sig" in a prescription is to ensure that the patient understands how to correctly use the medication prescribed to them.

The other options refer to specific components related to prescriptions but do not accurately represent the meaning of "Sig." For instance, dosage amount pertains to how much of the medication should be taken, medication type identifies the specific drug being prescribed, and administration route describes how the medication should be given (such as orally, topically, etc.). However, "Sig" specifically focuses on the labeling or instructions for usage that accompany the medication.
