Final answer:
A single Schedule II (CII) drug can typically be prescribed per prescription blank, according to DEA regulations aimed at minimizing prescription errors and abuse.
Step-by-step explanation:
The question refers to the regulations around prescribing controlled substances, specifically Schedule II drugs (CII), which are classified under the Controlled Substances Act due to their potential for abuse and dependence. The query is about how many drugs classified as CII can be prescribed per prescription blank.
Under U.S. federal regulations, particularly those enforced by the Drug Enforcement Administration (DEA), there is a rule that typically only one CII prescription can be written per prescription blank. The intention behind this is to minimize errors and the risk of prescription fraud or abuse. However, depending on the state law and the specific circumstances, exceptions may apply which allow for more than one prescription on a blank, such as electronic prescribing systems that have built-in safeguards.
