What is the primary characteristic of Schedule IV substances?

The primary characteristic of Schedule IV substances is that they have limited potential for dependence while still having accepted medical use. These substances are considered to have a lower risk of abuse compared to substances in higher schedules. In a clinical context, Schedule IV drugs are often prescribed for various medical conditions due to their therapeutic benefits, but they are also monitored due to their potential for misuse and dependency.

This classification allows for patients to safely access medications that can effectively treat their conditions while using precautions in prescribing and monitoring their use. The existence of accepted medical use distinguishes these substances from those that have no medical applications, which would fall under Schedule I. Therefore, the defining feature of Schedule IV substances is their balance of medical utility along with a lower potential for addiction compared to higher schedules.
