What is needed on the drug label regarding the drug's strength?

The correct choice emphasizes the importance of including both the proprietary (brand) name or the generic name of the drug, along with its strength, on the drug label. This labeling requirement ensures that healthcare professionals and patients can accurately identify the medication and understand the dosage being dispensed.

Including the strength is crucial for safe medication use, as it allows for proper dosing and minimizes the risk of medication errors. Patients and providers must know how much active ingredient is in each dosage form to avoid underdosing or overdosing.

In contrast, options that suggest only the brand name or generic name, or only the drug class, fall short of the comprehensive information necessary for safe medication dispensing. The absence of strength information could lead to confusion and potential health risks for patients relying on the label for their treatment. Thus, including the combined details of the name and strength on a drug label is essential in promoting effective communication regarding medication use.
