What is defined as a device or drug unsafe for self-medication?

The term "dangerous drug" refers specifically to substances that are deemed unsafe for use without medical supervision. These drugs carry risks of severe side effects, misuse, or dependence, making them inappropriate for self-medication. They often require a prescription because their safety and effectiveness depend on a healthcare professional's guidance and oversight. This classification indicates that these drugs have the potential for harm if used improperly, which underscores the importance of consulting with a doctor to ensure they are prescribed correctly and safely.

In contrast, controlled substances are a broader legal category that includes both dangerous drugs and other substances regulated due to their potential for abuse. Prescription drugs also require oversight but may not fall into the category of dangerous drugs, as some can be safely self-administered under the guidance of a healthcare provider. Over-the-counter drugs, on the other hand, are deemed safe for consumer use without a prescription and typically do not pose the same level of risk associated with dangerous drugs.
