What does the term "dangerous drug" refer to?

The term "dangerous drug" specifically refers to medications that are deemed not safe for general use without the supervision of a licensed healthcare provider. This classification is indicated by the presence of the label "RX ONLY" on the commercial packaging of these drugs. Such a label signifies that the drug requires a prescription for dispensation, highlighting that it can pose significant risks of harm if misused or taken without professional guidance. This requirement is often due to potential severe side effects, risks of addiction, or the need for careful monitoring of the patient's condition while using the medication.

In contrast, drugs that are available without a prescription do not carry the same level of risk and therefore are classified differently. While some drugs can have adverse side effects, not all side effects warrant a drug being labeled as "dangerous." Additionally, not all drugs controlled by the FDA necessarily fit this definition, as the term encompasses a specific regulatory designation related to the necessity of a prescription.
