Which information is NOT required on a prescription label?

The correct answer is that the patient's address is not required on a prescription label. While including the patient's address might be helpful for identification and record-keeping purposes, it is not a mandatory element according to standard pharmacy labeling requirements. Instead, the focus is placed on providing information that is essential for the safe and effective use of the medication.

Other elements such as the name and address of the pharmacy, the manufacturer's name, and directions for use are critical for ensuring that the patient knows where to get additional assistance, how to properly take the medication, and to which company the medication is associated. Including these details enhances patient safety and facilitates proper medication management. Thus, the lack of a requirement for the patient's address allows for streamlined labeling while maintaining essential safety information.
