Final answer:
The 'Sig' part of a prescription provides directions to the pharmacist. It includes the dosage, frequency, and method of taking the medication, ensuring patients properly follow their medication regimen.
Step-by-step explanation:
The part of a prescription that provides directions to the pharmacist is marked with the abbreviation 'Sig' which stands for 'Signatura'. This section of the prescription tells the pharmacist how the medication is to be taken by the patient. It includes instructions on the dosage, frequency, and method of administration. The pharmacist, who must hold a doctorate in pharmacy and be licensed, will use this information to label the medication appropriately so that the patient understands how to properly take their medication.
For example, a Sig might read '2 tabs po q6h prn pain' which translates to 'take two tablets by mouth every 6 hours as needed for pain'. This critical role of the pharmacist ensures that the physician's medication orders are correctly translated into patient instructions, supporting the health and well-being of the patient.
