A drug that requires a prescription is called what?

• A. OTC drug
• B. Emetic
• C. Legend drug
• D. Strength

Answer: (C)

The main idea here is understanding the difference between medicines that need a doctor’s oversight and those you can buy without one. A drug that requires a prescription is called a legend drug. The label on these medicines indicates they’re Rx-only, meaning a pharmacist dispenses them only under a physician’s orders because they can have serious side effects, interact with other medicines, or require medical monitoring to use safely. This safety net helps ensure they’re used correctly and effectively.

In contrast, OTC drugs are sold without a prescription because they’re considered safe and effective for general use when directions on the label are followed. An emetic is simply a substance that causes vomiting, not a term about prescription status, and “strength” refers to the dose or potency, not whether a prescription is needed.
