Which term describes medications legally available only by prescription?

• A. Alcohol
• B. Illegal drugs
• C. Acute
• D. Rx drugs

Answer: (D)

Prescription status determines how a medication may be obtained. Medications that require a clinician’s order are called Rx drugs. The need for a prescription exists because these drugs can have serious side effects, interact with other medicines, or require careful dosing and monitoring. A doctor decides when a drug is appropriate, how much to take, and for how long, and the pharmacist verifies the prescription and can provide guidance on safe use. Other terms don’t describe this access pattern: alcohol is a separate substance with its own legal rules, illegal drugs are not legally available, and acute is a descriptor of onset or severity, not how a drug is accessed. So the description that fits “medications legally available only by prescription” is Rx drugs.
