Final answer:
A pharmacist is prohibited from changing the patient's name, the specific controlled substance prescribed, and the prescriber's signature on a Schedule II controlled substance prescription.
Step-by-step explanation:
Elements of a C-II Prescription That Cannot Be Changed:
Pharmacists cannot change the patient's name, controlled substance prescribed (except for minor spelling errors), or the prescriber's signature on a C-II prescription. In the context of pharmacy regulations, a C-II prescription refers to a prescription for a Schedule II controlled substance, which is held to stringent standards due to its high potential for abuse.
Basic demographic information of the patient, such as address, may be modified if incorrect or missing. Additionally, the pharmacist may not alter the date of issuance or the total quantity prescribed. It is crucial that pharmacists adhere to these regulations to ensure compliance with law and to protect patient safety. Minor corrections to spelling errors may be permissible as long as they do not change the drug or the strength prescribed.
