ADDERALL XR is a once-daily treatment for ADHD (attention-deficit/hyperactivity disorder).

How does ADDERALL XR work?
ADDERALL XR is thought to work by restoring the balance between certain chemicals in the brain to help provide better focus and attention.

ADHD and brain chemicals
Two brain chemicals in particular—dopamine and norepinephrine—are believed to play an important role in our ability to focus and pay attention to tasks.³ ADDERALL XR is thought to restore the balance of the naturally occurring brain chemicals, dopamine and norepinephrine, available in the brain.⁷

The active ingredient in ADDERALL XR has been used medically for nearly 70 years.⁷

Once-a-day formula for all-day effectiveness
The ADDERALL XR capsule is designed to work effectively for up to
12 hours.⁹ A single dose of ADDERALL XR in the morning can control your ADHD symptoms throughout the day.¹

Busy adults appreciate the advantages of once-daily dosing over shorter-acting ADHD formulas:

• Once-daily may be more convenient because you don’t have to remember to take another pill in the middle of your day¹
• Once-daily may be more effective because you don’t have the drop in symptom control that can happen when a mid-day dose is forgotten¹
