Adderall is generally well tolerated and effective in treating the symptoms of ADHD and narcolepsy. At therapeutic doses, Adderall causes emotional and cognitive effects such as euphoria, change in sex drive, increased wakefulness, and improved cognitive control. At these doses, it induces physical effects such as a faster reaction time, fatigue resistance, and increased muscle strength. In contrast, much larger doses of Adderall can impair cognitive control, cause rapid muscle breakdown, provoke panic attacks, or induce a psychosis (e.g., paranoia, delusions, hallucinations). The side effects of Adderall vary widely among individuals, but most commonly include insomnia, dry mouth, loss of appetite, and weight loss. The risk of developing an addiction or dependence is insignificant when Adderall is used as prescribed at fairly low daily doses, such as those used for treating ADHD; however, the routine use of Adderall in larger daily doses poses a significant risk of addiction or dependence due to the pronounced reinforcing effects that are present at high doses. Recreational doses of amphetamine are generally much larger than prescribed therapeutic doses, and carry a far greater risk of serious adverse effects.
