S.C. Code Regs. § § 61-4.500.506
Controlled substances which are dispensed directly to an ultimate user other than by a prescription dispensed by a pharmacy or by direct administration or application of the substance into or upon the person for whom it is intended, shall bear a label or labeling containing the drug name, the quantity dispensed, the name and address of the dispenser, the name of the ultimate user (i.e., the "patient"), specific directions for use, and the date of the dispensing. The label or labeling shall include any necessary cautionary statement, whether customary or required by state or federal law. A serial number may be utilized at the discretion of the dispenser. The act of dispensing controlled substances shall be performed by the registrant, and shall not be delegated to any person other than a pharmacist acting in the regular course of professional activity. Prescriptions shall be labeled pursuant to the provisions of Part 1000 of this Regulation, unless specifically exempted. No practitioner shall directly dispense more than a thirty-one day supply.
