What is required when a pharmacist dispenses a controlled substance?

Providing educational materials to the patient is important when a pharmacist dispenses a controlled substance because it promotes safe use and understanding of the medication. Patients receiving controlled substances often have specific instructions, warnings, or guidelines that are crucial for ensuring that the medication is used safely and effectively. These educational materials can include information about potential side effects, proper dosage, the importance of adhering to the prescribed treatment plan, and the risks of misuse or dependency. By providing this information, pharmacists play a critical role in patient safety and in preventing medication-related issues.

The other options, while relevant in different contexts, do not specifically address the critical educational aspect of dispensing controlled substances. Recording the transaction, verifying insurance, and ensuring availability of prescribed quantities are all necessary operational tasks, but these do not contribute directly to patient understanding and safety regarding the use of controlled substances.
