Final answer:
A CII prescription cannot be transferred between pharmacies or individuals because it is a Schedule II controlled substance. The DEA allows a one-time transfer only if pharmacies share a real-time, online database.
Step-by-step explanation:
The question pertains to how many times a CII prescription can be transferred. Controlled substances listed in Schedule II (CII) have strict regulations due to their high potential for abuse and dependence. In the United States, according to the Drug Enforcement Administration (DEA), CII prescriptions are not transferable. Once a CII prescription is filled, it cannot be transferred to another pharmacy or individual. The only exception occurs when pharmacies share a real-time, online database, and even then, it can only be transferred once.
