U.S. federal classification
Listed federally in Schedule II. Classification does not by itself establish that a particular product is approved or that an online transaction is lawful. State requirements and product-specific rules also apply.
Sources: DEA — Controlled substances alphabetical list (October 2026)
Pharmacology and mechanism
Amphetamine increases central dopamine and norepinephrine activity. Its effects on alertness and attention occur alongside possible effects on appetite, sleep, blood pressure and heart rate.
Formulations and product identification
The active ingredient alone does not describe a finished product. These distinctions matter when reading a label or comparing prescriptions.
| Product or formulation | Important distinction |
|---|---|
| Single-ingredient amphetamine | Not the same product description as mixed amphetamine salts. |
| Mixed amphetamine salts | Adderall is one familiar brand context. |
| Dextroamphetamine | A related active ingredient with its own products. |
Monitoring and treatment follow-up
Routine review may include treatment response, blood pressure, pulse, appetite and sleep. In children, growth and weight trends are relevant. New psychiatric or cardiovascular symptoms require assessment.
Dependence and stopping treatment
Misuse and addiction are recognized risks. Taking someone else’s stimulant, escalating independently or changing the intended route can increase harm. Physical adaptation during treatment should be distinguished from a substance use disorder.
How it differs from related medicines
Amphetamine, lisdexamfetamine and methylphenidate are not milligram-for-milligram substitutes. Lisdexamfetamine is a prodrug, while methylphenidate is a different molecule. A switch requires a new clinical treatment decision.
