If a pharmacist substitutes generic Metoprolol for the brand name Lopressor, what should be on the dispensing label?

The correct choice indicates that the dispensing label should list "Metoprolol (Mylan)." This is important for several reasons.

First, it identifies both the generic name of the medication, which is essential for patient understanding and safety, and the manufacturer of that specific generic formulation, which helps the patient identify the specific product they received. This information is particularly useful if the patient has concerns about a specific manufacturer due to previous experiences or preferences. Including the manufacturer's name can also aid in communication between the pharmacy and the prescriber, as well as when addressing any issues related to product recalls or effectiveness.

In contrast, using "Lopressor (Pfizer)" would not be appropriate because it does not accurately represent the medication that was dispensed. While "Metoprolol generic" may convey the type of medication, it lacks the specificity of the manufacturer, which is important for both patient safety and legal reasons. Lastly, "Metoprolol" alone fails to provide enough context for the patient to understand which formulation or manufacturer they are receiving, which is why it is less optimal compared to the correct answer.
