What is the main difference between a "prescription" and an "over-the-counter" drug?

The main distinction between a prescription drug and an over-the-counter (OTC) drug lies in the requirement for a doctor's order. Prescription drugs necessitate a healthcare professional's approval to ensure that they are being used appropriately based on a patient's specific medical condition, history, and potential for adverse effects. This regulation is crucial as prescription medications often carry a higher risk of side effects, misuse, or dependency.

On the other hand, over-the-counter drugs are considered safe for general use without the supervision of a healthcare provider. As they have a well-established safety profile for treating minor ailments, consumers can easily purchase them at pharmacies, supermarkets, and other retail outlets without needing a prescription.

The information about the availability of prescription drugs online, the locations where OTC drugs can be found, or the forms that these drugs take does not fundamentally clarify the regulatory and safety distinctions that define prescription versus OTC medications.
