Which of the following is a requirement for labeling controlled substances (CS)?

Labeling for controlled substances has specific requirements to ensure that patients and caregivers understand the restrictions associated with the medication's use. The requirement stating "Caution: Federal Law prohibits the transfer of this drug to any person other than the patient for whom it was prescribed" is vital for compliance with the Controlled Substances Act. This warning informs individuals that controlled substances cannot be shared or transferred to others, emphasizing the importance of safeguarding medications due to their potential for abuse and the legal consequences of improper distribution.

This requirement serves a crucial role in promoting safe medication practices and aligns with federal regulations that aim to minimize the misuse of controlled substances. By clearly labeling this information, pharmacists can help prevent diversion and misuse, which are prevalent concerns associated with these types of drugs.

Other labeling options, while they may provide useful information, do not specifically address the legal restrictions associated with controlled substances as mandated by federal law.
