Iowa Admin. Code r. 657-23.15
A pharmacy shall not accept from a patient or facility for reuse or resale any drug or device unless, in the professional judgment of the pharmacist, the integrity of the drug or device has not in any way been compromised. Under no circumstances shall a pharmacist accept from a patient or facility any controlled substances except for reuse by the same patient. Prescription drugs, excluding controlled substances, dispensed in a unit dose dispensing system pursuant to 657-Chapter 22 may, however, be returned and reused as authorized in 657-subrule 22.1(6). No items of a personal contact nature which have been removed from the original package or container after dispensing shall be accepted for return, exchanged, or resold by any pharmacist.
