Although Adderall is a commonly used medication in the United States to treat symptoms of ADHD, it is not without hazards. Although it works well to increase focus and decrease hyperactivity, its stimulant qualities leave it open to abuse and dependence. Therefore, in order to balance Adderall's benefits and potential adverse effects—which could include anxiety, sleeplessness, and an elevated heart rate—it is imperative that the medication be used properly under medical supervision.
