S.C. Code Ann. § 40-43-84
(C) An intern/extern may engage in the practice of pharmacy if such activities are under the direct supervision of a licensed pharmacist. A pharmacist must be in continuous personal eye and voice contact with, and actually giving instructions to, the intern/extern during all professional activities throughout the entire period of the internship/externship. The pharmacist shall physically review the prescription drug order and the dispensed product before the product is delivered to the patient or the patient's agent. The pharmacist is responsible for the work of the intern/extern. A pharmacist may not supervise more than one intern at any one time.
Pharmacy interns/externs shall not be left in sole charge of a prescription department or other approved site at any time. Violation of this may result in cancellation of any and all internship/externship hours toward licensure that may have been accrued by the intern/extern, and may, in the discretion of the board, cause the board after sufficient notice to the pharmacy intern/extern, to revoke or suspend the internship certificate as provided above. The supervising pharmacist or designated pharmacist may also be subject to disciplinary action by the board.
An applicant for licensure, who is guilty of compounding or dispensing a prescription of a practitioner or selling legend drugs or medicines while not under the supervision of a licensed pharmacist may be refused licensure.
