Final answer:
The number of days supply on a CII drug depends on the specific drug and the prescribing regulations. In the US, CII drugs can only have a maximum of a 30-day supply.
Step-by-step explanation:
The number of days supply on a CII drug that can be dispensed depends on various factors, including the specific drug and the prescribing regulations of the state or country. In general, CII drugs are classified as controlled substances with a high potential for abuse and dependence, so their dispensing is heavily regulated.
For example, in the United States, CII drugs are subject to the rules set by the Drug Enforcement Administration (DEA). According to DEA regulations, CII drugs cannot be refilled, and each prescription can only have a maximum of a 30-day supply. However, some states may have additional restrictions or limitations.
It is important for both prescribers and pharmacists to adhere to these regulations to ensure proper handling and dispensing of CII drugs and to prevent potential misuse or diversion.
