What type of medication requires a patient to have a written prescription from a licensed practitioner?

Prescription drugs require a patient to have a written prescription from a licensed practitioner because they are used to treat specific medical conditions and have potential risks or side effects that necessitate professional oversight. This category of medication includes substances that may not be safe or appropriate for self-administration without guidance, as they can interact with other medications, have contraindications, or require monitoring for effectiveness and safety.

Over-the-counter drugs, by contrast, can be purchased without a prescription, as they are generally considered safe for public use when used as directed. Generic medications are equivalent to their brand-name counterparts in dosage form, strength, and administration, but they still fall under the prescription or over-the-counter classification depending on the original drug. Herbal supplements are typically available without a prescription as well, presenting them under a different regulatory standard compared to prescription drugs. Therefore, only prescription drugs specifically require a licensed practitioner’s written authorization.
