The science behind Adderall — attention-deficit/hyperactivity disorder Learn how the popular behavior-modifying amphetamine Adderall works.

When the effects of ADHD medication begin to wear off, individuals may experience a return or intensification of certain symptoms. Specifically, as the medication's influence diminishes, patients may notice the development of mood swings, increased hyperactivity, or fatigue.1

These changes occur because the stimulants used to treat the condition—such as methylphenidate or amphetamine—are designed to help regulate attention and behavior by increasing the activity of neurotransmitters like norepinephrine in the brain. When the drug is no longer active in the system, the therapeutic "calming" or focusing effect subsides, which can lead to these fluctuations in mood and energy levels.1

If you are noticing these "rebound" effects, it is important to consult with a healthcare provider, as they may adjust the dosage or the type of medication—such as switching between short-acting and long-acting formulations—to help maintain more consistent symptom control throughout the day.1
