Which of the following is not required on a dispensing container label?

In Massachusetts, as with many states, the requirements for labeling dispensing containers are designed to ensure that patients receive clear and comprehensive information about their medications. One key aspect of these requirements is that the label must include pertinent information that supports safe and effective medication usage.

The name of the manufacturer is not a required element on a dispensing container label. While knowing the manufacturer can be useful for various reasons—such as tracking recalls or verifying medication identity—state and federal regulations emphasize the necessity of information that directly impacts patient safety and usage. The unique prescription identification number, the name of the prescribing practitioner, and the initials of the dispensing pharmacist all play critical roles in ensuring that the patient receives the correct medication, understands who prescribed it, and can trace who dispensed it in case of questions or issues.

In summary, while there are several important details mandated on pharmacy labels to ensure patient safety and compliance, the manufacturer's name is typically not among them, which makes it the correct answer to this question.
