S.C. Code Regs. § § 61-4.1900.1913
It is unlawful for a hospital to dispense controlled substances to outpatients on physicians' orders. Such dispensing shall be done only on the prescription of a duly licensed physician and only from the pharmacy holding a permit as a retail pharmacy of a hospital registered under Article 3 of Chapter 53 of Title 44 of the 1976 Code, and by or under the immediate supervision of a registered pharmacist. With the permission of the hospital, a practitioner may personally dispense limited quantities of controlled substances to their patients for take-home purposes, provided that such substances are properly packaged and labeled as required by provisions elsewhere within this regulation, and in compliance with statutory provisions.
