What information must be included on a prescription label according to regulatory agencies?

The information that must be included on a prescription label according to regulatory agencies is the medication dosage and instructions for use. This requirement ensures that patients understand how to properly take their medication, which directly impacts their safety and the effectiveness of their treatment. Clear dosage instructions help to prevent underdosing or overdosing, both of which can lead to adverse health effects or treatment failures. Regulatory agencies emphasize this information to protect patients and promote safe medication practices.

While other items, such as a prescriber's social security number, pharmacy owner's contact information, or a patient’s insurance details, may be relevant in certain contexts, they are not essential elements mandated to appear on every prescription label. The focus is primarily on providing patients with the critical information needed for their medication administration.
