Which of the following is NOT required on the manufacturer's drug container label for an oral drug product?

The requirement for manufacturer's drug container labels for oral drug products is governed by various regulations to ensure safe and effective use of the medication. One of the critical components involves providing users with necessary information about the drug's use, safety, and storage.

While warnings for adverse reactions, drug interaction information, and storage conditions are essential to inform the patient or caregiver about the safety and handling of the drug, directions for administration are generally not explicitly required on the container label itself. Instead, they are typically included in the labeling associated with the prescription or in patient information leaflets that accompany the product. These details provide guidance on how to properly take the medication but are designed more for accompanying documentation rather than the container label.

Thus, while providing directions for administration is important, it is not a direct requirement on the manufacturer's drug container label itself, making it the correct choice in this question.
