Adverse Reactions

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Clinical Studies Experience

The premarketing development program for Adderall XR included exposures in a total of 1315 participants in clinical trials (635 pediatric patients, 350 adolescent patients, 248 adult patients, and 82 healthy adult subjects). Of these, 635 patients (ages 6 to 12) were evaluated in two controlled clinical studies, one open-label clinical study, and two single-dose clinical pharmacology studies (N= 40). Safety data on all patients are included in the discussion that follows. Adverse reactions were assessed by collecting adverse reactions, results of physical examinations, vital signs, weights, laboratory analyses, and ECGs.

Adverse reactions during exposure were obtained primarily by general inquiry and recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse reactions without first grouping similar types of reactions into a smaller number of standardized event categories. In the tables and listings that follow, COSTART terminology has been used to classify reported adverse reactions.

The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse event of the type listed.

Adverse Reactions Leading to Discontinuation of Treatment

In two placebo-controlled studies of up to 5 weeks duration among children with ADHD, 2.4% (10/425) of Adderall XR-treated patients discontinued due to adverse reactions (including 3 patients with loss of appetite, one of whom also reported insomnia) compared to 2.7% (7/259) receiving placebo.

The most frequent adverse reactions leading to discontinuation of Adderall XR in controlled and uncontrolled, multiple-dose clinical trials of children (N=595) were anorexia (loss of appetite) (2.9%), insomnia (1.5%), weight loss (1.2%), emotional lability (1%), and depression (0.7%). Over half of these patients were exposed to Adderall XR for 12 months or more.

In a separate placebo-controlled 4-week study in adolescents with ADHD, five patients (2.1%) discontinued treatment due to adverse events among Adderall XR-treated patients (N=233) compared to none who received placebo (N=54). The most frequent adverse event leading to discontinuation and considered to be drug-related (i.e. leading to discontinuation in at least 1% of Adderall XR-treated patients and at a rate at least twice that of placebo) was insomnia (1.3%, n=3).

In one placebo-controlled 4-week study among adults with ADHD with doses 20 mg to 60 mg, 23 patients (12.0%) discontinued treatment due to adverse events among Adderall XR-treated patients (N=191) compared to one patient (1.6%) who received placebo (N=64). The most frequent adverse events leading to discontinuation and considered to be drug-related (i.e. leading to discontinuation in at least 1% of Adderall XR-treated patients and at a rate at least twice that of placebo) were insomnia (5.2%, n=10), anxiety (2.1%, n=4), nervousness (1.6%, n=3), dry mouth (1.6%, n=3), anorexia (1.6%, n=3), tachycardia (1.6%, n=3), headache (1.6%, n=3), and asthenia (1.0%, n=2).

Hypertension [see WARNINGS AND PRECAUTIONS (5.1)]

In a controlled 4-week outpatient clinical study of adolescents with ADHD, isolated systolic blood pressure elevations ≥15 mmHg were observed in 7/64 (11%) placebo-treated patients and 7/100 (7%) patients receiving Adderall XR 10 or 20 mg. Isolated elevations in diastolic blood pressure ≥ 8 mmHg were observed in 16/64 (25%) placebo-treated patients and 22/100 (22%) Adderall XR-treated patients. Similar results were observed at higher doses.

In a single-dose pharmacokinetic study in 23 adolescents with ADHD, isolated increases in systolic blood pressure (above the upper 95% CI for age, gender, and stature) were observed in 2/17 (12%) and 8/23 (35%), subjects administered 10 mg and 20 mg Adderall XR, respectively. Higher single doses were associated with a greater increase in systolic blood pressure. All increases were transient, appeared maximal at 2 to 4 hours post dose and not associated with symptoms.

Black Box Warnings

Amphetamines have a high potential for abuse

Administration for prolonged periods may lead to dependence and must be avoided

Assess the possibility of persons obtaining amphetamines for nontherapeutic use or distribution to others

Prescribed or dispensed sparingly

Misuse of amphetamines may cause sudden death and serious cardiovascular adverse events





Hypertension, advanced arteriosclerosis, symptomatic CVD

Symptomatic cardiovascular disease

Moderate-to-severe hypertension

Agitated states, history of drug abuse

MAO inhibitors given within 14 days (risk of severe hypertensive reaction)


Preexisting cardiac structural abnormalities associated with risk of sudden death (if abused)

Time to maximum concentration decreased when coadministered with acid-suppressing drugs (eg, proton pump inhibitors)

Associated with peripheral vasculopathy, including Raynaud phenomenon

Difficulties with accommodation and blurring of vision have been reported with stimulant treatment

May impair ability to engage in potentially hazardouse activities due to CNS effects

Potential exists for drug dependency

Use caution in hypertension, history of psychosis, seizure disorders, elderly, or Tourette's syndrome (may unmask tics)

Abrupt discontinuation may result in symptoms for withdrawal

Sudden deaths, stroke, and myocardial infarction reported in adults taking stimulants at usual doses

Patients who develop symptoms such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease during stimulant treatment should undergo a prompt cardiac evaluation

Particular care should be taken in using stimulants to treat ADHD patients with comorbid bipolar disorder because of concern for possible induction of mixed/manic episode in such patients

Aggressive behavior or hostility is often observed in children and adolescents with ADHD; monitor for the appearance of or worsening of aggressive behavior or hostility

Monitor growth of children ages 7 to 10 years during treatment with stimulants; may need to interrupt therapy in patients not growing or gaining weight as expected

Stimulants may lower convulsive threshold in patients with prior history of seizure, patients with prior EEG abnormalities in absence of seizures, and very rarely, patients without a history of seizures and no prior EEG evidence of seizures; discontinue therapy in the presence of seizures

Use with caution in patients who use other sympathomimetic drugs

Amphetamines may exacerbate motor and phonic tics and Tourette’s syndrome; perform clinical evaluation for tics and Tourette’s syndrome in children and their families prior to treating with stimulant medications

Rare instances of prolonged and sometimes painful erections (priapism), sometimes requiring surgical intervention, reported with methylphenidate products; typically not reported during initiation, but often subsequent to an increase in dose; seek immediate medical attention for abnormally sustained or frequent and painful erections

Drug interaction overview

  • Serotonin syndrome, a potentially life-threatening reaction, may occur when amphetamines are used in combination with other drugs that affect the serotonergic neurotransmitter systems such as monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John’s Wort
  • Amphetamines and amphetamine derivatives are known to be metabolized, to some degree, by cytochrome P450 2D6 (CYP2D6) and display minor inhibition of CYP2D6 metabolism; potential for a pharmacokinetic interaction exists with coadministration of CYP2D6 inhibitors which may increase risk with increased exposure to amphetamines and derivatives; in these situations, consider alternative non-serotonergic drug or alternative drug that does not inhibit CYP2D6
  • If concomitant use with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate therapy with lower doses, monitor patients for emergence of serotonin syndrome during drug initiation or titration, and inform patients of increased risk for serotonin syndrome

How it works

Adderall is a long-acting, amphetamine-type product that consists of different amphetamine salts (dextroamphetamine saccharate and sulfate, amphetamine aspartate and sulfate). Experts aren't sure exactly how Adderall works in ADHD but think it affects the reuptake of dopamine and norepinephrine, two neurotransmitters. Adderall is a central nervous system (CNS) stimulant.

Bottom Line

Adderall XR is a long-acting, once-daily formulation that combines four different amphetamine salts into one product and is used for the treatment of ADHD. Its use is limited by its potential to be addictive and cause dependence.


  • Take in the morning. Avoid taking in the afternoon because of the potential for insomnia.
  • May be taken with or without food.
  • Adderall XR capsules may be swallowed whole, or the capsule opened and the contents mixed with applesauce and consumed immediately, without chewing. Do not attempt to divide contents of a capsule or store mixed applesauce/Adderall XR product.
  • Administer at the lowest effective dosage and take exactly as directed by your doctor; never increase dosage without their advice.
  • Avoid sudden discontinuation as this can precipitate a withdrawal reaction.
  • Seek medical advice if symptoms persist or worsen despite treatment, or if new psychotic symptoms (eg, hearing voices, signs of paranoia) develop.
  • Seek urgent medical help if chest pain, shortness of breath or fainting is experienced while taking Adderall.
  • Do not drive or operate machinery if Adderal XRl impairs your judgment or reaction skills.
  • Seek medical advice if any new numbness, pain, skin color change or sensitivity or unexplained wounds occur in fingers or toes.
  • If you notice any changes in your mental state (such as feeling agitated, hallucinations), dizziness, fast heart rate, flushing, incoordination, tremor, rigidity, nausea or vomiting, seek urgent medical advice.
