Phenobarbital is classified as which type of controlled substance?

Phenobarbital is classified as a Schedule IV controlled substance. This classification indicates that while phenobarbital has accepted medical uses, such as in the treatment of seizures, it also has potential for abuse and dependence, but to a lesser degree compared to substances classified as Schedule I through III. Schedule IV drugs generally have lower risks of abuse and lower potential for dependence.

In this context, Schedule IV includes drugs that are considered to have a relatively low potential for addiction and are accepted for medical use, making them more accessible for patient care while still being regulated to prevent misuse. The scheduling system reflects the balance between their therapeutic value and their risks.
