Which of the following is NOT allowed to be added to a C-II prescription by a pharmacist?

In the context of controlled substances, particularly Schedule II (C-II) prescriptions, specific regulations dictate what changes can be made by a pharmacist. The option that is not allowed to be added to a C-II prescription is the signature.

A pharmacist cannot add or modify the prescriber’s signature on a C-II prescription. The prescriber’s signature is a crucial element that validates the prescription, and any alteration compromises its integrity and legal standing. The law is strict about maintaining the original authenticity of the prescription, and any tampering or unauthorized addition in that regard is prohibited.

On the other hand, alterations such as quantity, date, or directions for use may be permitted under certain conditions, especially if they are in accordance with state regulations and do not invalidate the prescription. However, changes should be made in consultation with the prescriber to ensure compliance with legal standards and patient safety.

Thus, the inability to modify or add to a prescriber’s signature emphasizes the importance of original documentation in the dispensing of controlled substances and upholds the legal framework surrounding pharmaceuticals.
