Adderall, a combination of amphetamine and dextroamphetamine, is prescribed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy by improving focus and alertness. In the United States, it is a Schedule II controlled substance that requires a valid prescription from a licensed healthcare provider and must be dispensed only through authorized pharmacies. For patients with an active prescription, some reputable services offer overnight shipping for fast access. Choosing a trusted pharmacy ensures medication authenticity, proper handling, and compliance with all federal and state regulations.
