Adderall® (dextroamphetamine-amphetamine) is a prescription stimulant medication used to treat attention-deficit/hyperactivity disorder (ADHD) and narcolepsy, a sleep disorder marked by sudden sleep attacks and excessive sleepiness during the day.
The medication works by changing levels of certain chemicals in the brain, which helps increase attention and decrease restlessness. When used for ADHD, it’s typically prescribed alongside social and psychological therapy to help manage symptoms.
Adderall is usually taken two to three times daily, with or without food. Common side effects of Adderall include headache, dry mouth, constipation or diarrhea, nervousness, and weight loss. Rarely, the medication may cause a heart attack, stroke, or sudden death, particularly in people who have serious heart problems.
Adderall can be habit-forming, so it’s important to take this medication exactly as prescribed. Overuse can also cause serious heart problems or sudden death.

WARNING: ABUSE, MISUSE, AND ADDICTION
Adderall XR has a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants, including Adderall XR, can result in overdose and death:
Before prescribing Adderall XR, assess each patient’s risk for abuse, misuse, and addiction.
Educate patients and their families about these risks, proper storage of the drug, and proper disposal of any unused drug.
Throughout treatment, reassess each patient’s risk and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
Although possible side effects of the medication can include appetite suppression and subsequent weight loss, particularly in the early stages of treatment, Adderall is not approved or recommended for weight management.
Adderall improves symptoms of ADHD. People taking the medication may experience better focus and attention and reduced impulsivity, although each person may react to the medication differently. Adderall can also cause side effects such as nervousness.
Adderall should only be taken exactly as prescribed by a healthcare provider. Taking the medication without a prescription or not as directed can lead to dependence as well as serious health problems, including sudden death.
Adderall is not indicated for anxiety and may even worsen symptoms of anxiety, given that a common side effect is nervousness.
