What type of medication must have a prescription before it can be dispensed?

The correct answer is legend medication, which refers to prescription medications that require a doctor's authorization to dispense. These drugs are classified as "legend" because they carry a legal requirement that they should be dispensed only with a prescription, ensuring that healthcare providers can monitor their use and provide appropriate care to patients.

This classification is important because legend medications often have specific indications, contraindications, and potential side effects that necessitate professional oversight. Because they can carry greater risks or be used to treat more serious conditions, it is crucial for a healthcare professional to assess the appropriateness of treatment for each individual patient.

Over-the-counter medications are available for purchase without a prescription, allowing consumers to self-manage minor health conditions. Controlled substances, while also requiring prescriptions, represent a specific category of medication that is regulated more strictly due to their potential for abuse and dependence. Herbal supplements do not require prescriptions but can be purchased freely, although they may not have the same level of regulation as traditional medications.

Understanding these distinctions is key in the realm of pharmacy, as it ensures proper adherence to legal and safety guidelines.
