To which class/schedule does diazepam belong?

Diazepam is classified as a Schedule IV controlled substance. This classification indicates that diazepam has a lower potential for abuse compared to substances in higher schedules, such as Class I, II, and III. Despite having a potential for dependence, medications in Schedule IV are generally recognized for having accepted medical uses and are deemed to be less risky in terms of abuse relative to higher schedules.

In this case, Class IV includes drugs that are often prescribed for anxiety, insomnia, muscle spasms, and seizures, which applies to diazepam. Thus, the classification reflects its therapeutic benefits while acknowledging the need for regulation to prevent misuse and ensure safe administration.
