30 Miss. Code. R. 2640-1.12
A licensee must not be influenced in the prescribing of drugs, devices or appliances by a direct or indirect financial interest in a pharmaceutical firm, pharmacy or other supplier.
A licensee may own or operate a pharmacy if there is no resulting exploitation of patients. A licensee must not give patients prescriptions in code or enter into agreements with pharmacies or other suppliers regarding the filling of prescriptions by code. Patients are entitled to the same freedom of choice in selecting who will fill their prescription needs as they are in the choice of a provider. The prescription is a written direction for a therapeutic or corrective agent. A patient is entitled to a copy of the licensee's prescription for drugs or other devices as required by the principles of medical ethics. The patient has a right to have the prescription filled by any legal means. Where medication is to be dispensed or a prescription, excluding refills, called in to a pharmacist for medication, a licensee must inform each patient of that patient's right to a written prescription and the right to have the prescription filled wherever the patient wishes.
Patients have an ethically and legally recognized right to prompt access to the information contained in their individual medical records. The prescription is an essential part of the patient's medical record. If a patient requests a written prescription in lieu of an oral prescription, this request must be honored. Licensees must not discourage patients from requesting a written prescription or urge, suggest or direct in any manner that a patient fill a prescription at an establishment which has a direct telephone line or which has entered into a business or other preferential arrangement with the licensee with respect to the filling of the licensee's prescriptions.
