Which information is NOT required on a medication label?

The total cost of the medication is not required on a medication label. Medication labels typically need to include essential information that supports safe and effective use of the medication, such as the name of the prescriber, the date the pharmacy filled the medication, and the patient's name. This information is vital for ensuring the correct medication is supplied to the right patient under proper medical guidance. The total cost, however, is not a necessary component of the label itself. Standards focus more on clinical and patient safety details rather than on pricing information, which can vary and may not directly impact the administration or understanding of the medication.
