What must a pharmacist do before dispensing a controlled substance?

Before dispensing a controlled substance, it is essential for a pharmacist to review the state databank for previous prescriptions. This action is a critical part of ensuring patient safety and preventing prescription drug abuse. The state databank contains valuable information regarding a patient's prescription history, including any prior prescriptions for controlled substances they may have received. By accessing this information, the pharmacist can assess whether the patient might be seeking multiple prescriptions for the same controlled substances from different providers, which could indicate potential misuse or diversion of medication.

This review process also helps the pharmacist ensure that they are following the law and regulations governing the dispensing of controlled substances. It aids in identifying patients who may be at risk for addiction or have a history of substance abuse, thereby allowing the pharmacist to take necessary precautions, such as counseling the patient about the medication or contacting the prescriber for further clarification if needed.

The other options do not emphasize the critical legal and safety responsibilities associated with dispensing controlled substances. Checking a patient's insurance coverage, consulting with other pharmacies, or waiting for a prescriber's confirmation do not address the primary purpose of preventing misuse and ensuring appropriate medication management for the patient. Therefore, reviewing the state databank stands out as the most crucial activity a pharmacist must perform prior to dispensing a controlled substance.
