Why ADHD Medications Matter
Attention deficit hyperactivity disorder medications are among the most commonly prescribed controlled substances. Understanding their drug classes, schedules, and dispensing rules is important for both the PTCE and daily pharmacy practice.
Stimulant Medications
Most ADHD medications are stimulants classified as Schedule II controlled substances:
- Amphetamine/dextroamphetamine (Adderall, Adderall XR)
- Lisdexamfetamine (Vyvanse)
- Methylphenidate (Ritalin, Concerta, Focalin)
As Schedule II drugs, these cannot be refilled. A new prescription is required each time. Many are available in both immediate-release and extended-release formulations.
Non-Stimulant Options
Some ADHD medications are not controlled substances:
- Atomoxetine (Strattera) - a non-stimulant ADHD medication, not a controlled substance
- Guanfacine ER (Intuniv) - sometimes used for ADHD, not controlled
Dispensing Considerations
Schedule II medications require careful handling: no refills, specific prescription requirements, secure storage, and accurate inventory documentation. Shortages of ADHD medications can occur, requiring communication with patients and prescribers about availability.
Exam Focus
Know that most ADHD stimulants are Schedule II, recognize common brand/generic pairs, understand the no-refill rule for Schedule II, and be aware that non-stimulant alternatives exist. The controlled substance classification is the most commonly tested aspect of these medications.
