Final answer:
A pharmacist may only make limited changes to a CII-CV prescription after consultation with the prescribing physician, such as updating the patient's address or the dosage form, but not changes to the patient's name or the controlled substance prescribed.
Step-by-step explanation:
The pharmacist is a healthcare professional who dispenses drugs prescribed by a physician and provides valuable advice on drug selection, dosage, interactions, and side effects. When it comes to controlled substances, which are classified from CII (Schedule II) to CV (Schedule V) based on their potential for abuse, there are strict regulations regarding prescription modifications. A pharmacist may only make changes to a CII-CV prescription after consultation with the prescribing physician, and even then, changes are typically limited to certain non-critical areas such as the patient's address or the dosage form, but never the patient's name, controlled substance prescribed, or prescribing physician's signature.
