What must be included in prescription labels according to the Food, Drug, and Cosmetic Act?

The correct choice reflects the requirements outlined in the Food, Drug, and Cosmetic Act regarding prescription labels. According to this legislation, prescription labels must contain essential information that helps ensure the safe and effective use of a medication. This includes the drug name, which identifies the specific medication being dispensed, the strength, indicating the potency of the drug, and the quantity, which tells the patient how much of the drug they are receiving. This information is crucial for both healthcare providers and patients to avoid medication errors and to ensure appropriate dosing.

The inclusion of just the manufacturer's name, only the doctor’s name, or solely the expiration date does not provide comprehensive information necessary for proper medication management and patient safety. Thus, ensuring that the label contains the drug name, strength, and quantity fulfills the legal requirements and promotes informed use of the prescribed medication.
