Which of the following best describes prescription medications?

Prescription medications are specific drugs that require a doctor's order or authorization from a licensed healthcare professional before a patient can obtain them. This process is essential for ensuring that patients receive the appropriate medication tailored to their medical needs, safety, and health status. By requiring a prescription, healthcare providers can monitor the patient's health, provide necessary follow-up care, and manage any potential side effects or interactions with other medications the patient may be using.

The classification of prescription medications serves to protect patients, as some medications may have significant risks or may not be suitable for everyone. Only qualified professionals can evaluate the necessity and suitability of these medications for individual patients, ensuring safer use. Thus, option B accurately encapsulates this critical aspect of prescription medication management.
