Adderall is a prescription drug used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is a stimulant that works by increasing the production of neurotransmitters, which are chemicals that help improve concentration and focus. Adderall is a combination of amphetamine and dextroamphetamine, which are both central nervous system stimulants. Adderall can be used to help improve attention, concentration, and alertness in people with ADHD. It can also be used to help people stay awake during periods of sleep deprivation. Adderall can be prescribed in a variety of forms, including extended-release tablets and capsules, and immediate-release tablets. Common side effects of Adderall include insomnia, headache, stomach pain, loss of appetite, weight loss, and dry mouth. Adderall should be used only as prescribed by a doctor and should never be shared with another person. Taking too much Adderall can be dangerous and can lead to serious health problems, such as heart attack, stroke, and even death.
