What types of medications require written prescriptions?

The correct response identifies that written prescriptions are specifically required for medical devices, controlled drugs, and legend drugs.

Controlled drugs, which are substances categorized under schedules due to their potential for abuse or dependence, always necessitate a formal prescription. This requirement is in place to monitor their distribution and prevent misuse.

Legend drugs, also known as prescription medications, are those that are not available for purchase over-the-counter and can only be dispensed with a valid prescription from a licensed healthcare professional. This ensures that the use of these medications is appropriate and safe under the guidance of a practitioner.

Moreover, certain medical devices may also require a prescription to ensure that they are used correctly and effectively, complying with specific regulations regarding their purchase and use.

In contrast, over-the-counter medications and supplements do not require a prescription, as they are deemed safe for public use without the need for a healthcare provider’s supervision. Traditional herbs may also not always fall under the same regulatory requirement, leading to their general availability without prescription.

Thus, the selection accurately reflects that written prescriptions are necessary for these specific categories of medications and devices.
