Final answer:
The indication for which a drug is prescribed is required to be included on the prescription label for certain drugs in the United States.
Step-by-step explanation:
When a pharmacist is required to include the indication for which a drug is prescribed on the prescription label depends on the specific regulations of the country or region. In the United States, the FDA requires that the indication for use be included on the prescription label for certain drugs. These drugs are known as 'legend drugs' and the indication helps ensure proper use and understanding of the medication by the patient.
However, it's important to note that not all medications require the indication to be included on the label. Over-the-counter drugs, for example, may not have the indication listed. It's always a good idea to read and follow the instructions and information provided with any medication, including asking a pharmacist if any clarification is needed.
