Adderall is a prescription medication used to treat ADHD (Attention Deficit Hyperactivity Disorder) and narcolepsy. It contains a combination of amphetamine and dextroamphetamine, which are central nervous system stimulants that help improve focus, attention, and impulse control. Adderall works by increasing the levels of certain brain chemicals like dopamine and norepinephrine. It is available in immediate-release and extended-release forms. While effective, it carries a risk of side effects such as insomnia, anxiety, and appetite loss.
