What is the maximum dispensing quantity for a C-II controlled substance as a norm?

The maximum dispensing quantity for a C-II controlled substance is typically a 30-day supply. C-II medications are strictly regulated due to their potential for abuse and addiction. The 30-day limit aligns with federal regulations, which aim to control the dispensing of these substances while still allowing patients to receive necessary medication.

In most cases, prescriptions for C-II substances cannot be refilled. After the initial 30-day supply, patients would need a new prescription for additional medication, contributing to the overall monitoring and management of these prescriptions. This is an important safety measure designed to prevent misuse and ensure proper patient care.

The other options reflect shorter or longer durations that do not align with the standard regulations in most jurisdictions regarding C-II medications. Thus, the 30-day supply is the correct maximum dispensing quantity.
