Phenobarbital is classified under which schedule of controlled substances?

Phenobarbital is classified as a Schedule IV controlled substance under the Controlled Substances Act. This classification indicates that while it does have medicinal uses, it also has a lower potential for abuse and dependence compared to substances in higher schedules, such as Schedule II or Schedule III.

In Schedule IV, substances are permitted for prescription but are subject to specific regulations regarding their use and distribution. Phenobarbital is often utilized in the treatment of seizures and as a sedative, reflecting its therapeutic applications while maintaining a controlled status due to the risks associated with its misuse.

Understanding the classification of controlled substances is crucial for ensuring proper prescribing, dispensing, and monitoring practices, especially in the context of potential abuse and legal regulations governing these medications.
