Is phentermine a controlled substance?
Yes. Phentermine is classified as a controlled substance in the United States. It is regulated as a Schedule IV medication under the Controlled Substances Act.
What does Schedule IV mean for phentermine?
Schedule IV drugs generally have accepted medical uses but also carry risk for dependence and misuse. Because of that, phentermine prescribing and dispensing are subject to stricter rules than non-controlled medications (for example, it must be prescribed by a licensed clinician under controlled-substance requirements).
Is phentermine the same everywhere?
No. The controlled-substance status is specific to each country’s drug scheduling rules. In the U.S. it is Schedule IV, but rules can differ in other jurisdictions.
Why is phentermine controlled?
Phentermine is an amphetamine-like appetite suppressant. Its stimulant effects and potential for misuse or dependence are the basis for its controlled classification.
If it’s controlled, do pharmacies require special rules?
Typically, yes. Pharmacies handle controlled substances with additional documentation and dispensing controls compared with non-controlled drugs, following federal and state regulations.
