Contraindications
Amphetamine extended-release orally disintegrating tablets are contraindicated: In patients known to be hypersensitive to amphetamine, or other components of amphetamine extended-release orally disintegrating tablets. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other amphetamine products [see Adverse Reactions ( 6.2 )] . Patients taking monoamine oxidase inhibitors (MAOIs), or within 14 days of stopping MAOIs (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis [see Warnings and Precautions ( 5.7 ), Drug Interactions ( 7.1 )] .
Known hypersensitivity to amphetamine products or other ingredients in amphetamine extended-release orally disintegrating tablets. ( 4 ) Use of monoamine oxidase inhibitor (MAOI) or within 14 days of the last MAOI dose. ( 4 )
Risks to Patients with Serious Cardiac Disease: Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious heart arrhythmia, coronary artery disease, or other serious cardiac disease. ( 5.2 ) Increased Blood Pressure and Heart Rate: Monitor blood pressure and pulse. ( 5.3 ) Psychiatric Adverse Reactions: Prior to initiating amphetamine extended-release orally disintegrating tablets, screen patients for risk factors for developing a manic episode.
If new psychotic or manic symptoms occur, consider discontinuing amphetamine extended-release orally disintegrating tablets. ( 5.4 ) Long-Term Suppression of Growth in Pediatric Patients: Closely monitor growth (height and weight) in pediatric patients. Pediatric patients not growing or gaining height or weight as expected may need to have their treatment interrupted. ( 5.5 ) Peripheral Vasculopathy, including Raynaud’s phenomenon: Careful observation for digital changes is necessary during amphetamine extended-release orally disintegrating tablets treatment.
Further clinical evaluation (e.g., rheumatology referral) may be appropriate for patients who develop signs or symptoms of peripheral vasculopathy. ( 5.6 ) Serotonin Syndrome: Increased risk when coadministered with serotonergic agents (e.g., SSRIs, SNRIs, triptans), but also during overdosage situations. If it occurs, discontinue amphetamine extended-release orally disintegrating tablets and initiate supportive treatment.
( 5.7 , 17 ) Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating amphetamine extended-release orally disintegrating tablets, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor patients for the emergence or worsening of tics or Tourette’s syndrome. Discontinue treatment if clinically appropriate. ( 5.8 )
5.1Abuse, Misuse, and Addiction
Amphetamine extended-release orally disintegrating tablets have a high potential for abuse and misuse. The use of amphetamine extended-release orally disintegrating tablets exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Amphetamine extended-release orally disintegrating tablets can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse and Dependence ( 9.2 )] .
Misuse and abuse of CNS stimulants, including amphetamine extended-release orally disintegrating tablets, can result in overdose and death [see Overdosage ( 10 )] , and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection. Before prescribing amphetamine extended-release orally disintegrating tablets, assess each patient’s risk for abuse, misuse, and addiction.
Educate patients and their families about these risks and proper disposal of any unused drug. Advise patients to store amphetamine extended-release orally disintegrating tablets in a safe place, preferably locked, and instruct patients to not give amphetamine extended-release orally disintegrating tablets to anyone else. Throughout amphetamine extended-release orally disintegrating tablets treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
5.2Risks to Patients with Serious Cardiac Disease
Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were treated with CNS stimulants at the recommended ADHD dosage. Avoid amphetamine extended-release orally disintegrating tablets use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease.
5.3Increased Blood Pressure and Heart Rate
CNS stimulants cause an increase in blood pressure (mean increase about 2 to 4 mm Hg) and heart rate (mean increase about 3 to 6 bpm). Some patients may have larger increases. Monitor all amphetamine extended-release orally disintegrating tablets-treated patients for potential tachycardia and hypertension.
5.4Psychiatric Adverse Reactions Exacerbation of Pre-existing Psychosis
CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Disorder CNS stimulants may induce a manic or mixed episode in patients. Prior to initiating amphetamine extended-release orally disintegrating tablets treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or has a history of depressive symptoms or a family history of suicide, bipolar disorder, and depression).
New Psychotic or Manic Symptoms CNS stimulants, at the recommended dosage, may cause psychotic or manic symptoms, e.g., hallucinations, delusional thinking, or mania in patients without prior history of psychotic illness or mania. In a pooled analysis of multiple short-term, placebo-controlled studies of CNS stimulants, psychotic or manic symptoms occurred in 0.1% of CNS stimulant-treated patients compared to 0% of placebo-treated patients.
If such symptoms occur, consider discontinuing amphetamine extended-release orally disintegrating tablets.
5.5Long-Term Suppression of Growth in Pediatric Patients
Amphetamine extended-release orally disintegrating tablets are not approved for use and are not recommended in pediatric patients below 6 years of age [see Use in Specific Population ( 8.4 )] . CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Closely monitor growth (weight and height) in amphetamine extended-release orally disintegrating tablets-treated pediatric patients treated with CNS stimulants.
Pediatric patients not growing or gaining height or weight as expected may need to have their treatment interrupted.
5.6Peripheral
Vasculopathy, including Raynaud’s Phenomenon CNS stimulants, including amphetamine extended-release orally disintegrating tablets, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Signs and symptoms are usually intermittent and mild; however, sequelae have included digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud’s phenomenon, were observed in postmarketing reports and at the therapeutic dosage of CNS stimulants in all age groups throughout the course of treatment.
Signs and symptoms generally improved after dosage reduction or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during amphetamine extended-release orally disintegrating tablets-treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for amphetamine extended-release orally disintegrating tablets-treated patients who develop signs or symptoms of peripheral vasculopathy.
5.7Serotonin Syndrome
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 [see Drug Interactions ( 7.1) ] . The coadministration with cytochrome P450 2D6 (CYP2D6) inhibitors may also increase the risk with increased exposure to amphetamine extended-release orally disintegrating tablets. In these situations, consider an alternative non-serotonergic drug or an alternative drug that does not inhibit CYP2D6 [see Drug Interactions ( 7.1 ) ] . Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.

Interactions
Acidifying and Alkalinizing Agents: Agents that alter urinary pH can alter blood levels of amphetamine. Acidifying agents can decrease amphetamine blood levels, while alkalinizing agents can increase amphetamine blood levels. Adjust amphetamine extended-release orally disintegrating tablets dosage accordingly. ( 7.1 )
7.1Drugs Having Clinically Important Interactions with Amphetamines Table 5:
Drugs having clinically important interactions with amphetamines. MAO Inhibitors (MAOI) Clinical Impact MAOI antidepressants slow amphetamine metabolism, increasing amphetamines effect on the release of norepinephrine and other monoamines from adrenergic nerve endings causing headaches and other signs of hypertensive crisis. Toxic neurological effects and malignant hyperpyrexia can occur, sometimes with fatal results.
Intervention Do not administer amphetamine extended-release orally disintegrating tablets during or within 14 days following the administration of MAOI [see Contraindications ( 4 )] . Serotonergic Drugs Clinical Impact The concomitant use of amphetamine extended-release orally disintegrating tablets and serotonergic drugs increases the risk of serotonin syndrome. Intervention Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome, particularly during amphetamine extended-release orally disintegrating tablets initiation or dosage increase.
If serotonin syndrome occurs, discontinue amphetamine extended-release orally disintegrating tablets and the concomitant serotonergic drug(s) [see Warnings and Precautions ( 5.7 )] . Alkalinizing Agents Clinical Impact Increase blood levels and potentiate the action of amphetamine. Intervention Coadministration of amphetamine extended-release orally disintegrating tablets and gastrointestinal alkalinizing agents should be avoided.
Acidifying Agents Clinical Impact Lower blood levels and efficacy of amphetamines. Intervention Increase dose based on clinical response. Tricyclic Antidepressants Clinical Impact May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d-amphetamine in the brain; cardiovascular effects can be potentiated. Intervention Monitor frequently and adjust or use alternative therapy based on clinical response.
7.2Drug/Laboratory Test Interactions
Amphetamines can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening. Amphetamines may interfere with urinary steroid determinations.

8.1Pregnancy Risk Summary
Available data from epidemiologic studies and postmarketing reports on the use of amphetamine in pregnant women over decades of use have not identified a drug-associated risk of major birth defects or miscarriage. Neonates exposed to amphetamine in utero are at risk for withdrawal symptoms following delivery. Adverse pregnancy outcomes including premature delivery and low birth weight have been seen in infants born to mothers taking amphetamines during pregnancy (see Clinical Considerations).
No apparent effects on morphological development were observed in embryo-fetal development studies, with oral administration of amphetamine to rats and rabbits during organogenesis. However, in a pre- and post-natal development study, amphetamine (d- to l- ratio of 3:1) administered orally to pregnant rats during gestation and lactation caused a decrease in pup survival and a decrease in pup body weight that correlated with a delay in developmental landmarks at clinically relevant doses of amphetamine.
In addition, adverse effects on reproductive performance were observed in pups whose mothers were treated with amphetamine. Long-term neurochemical and behavioral effects have also been reported in animal developmental studies using clinically relevant doses of amphetamine ( see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Amphetamines, such as amphetamine extended-release orally disintegrating tablets, cause vasoconstriction and thereby may decrease placental perfusion. In addition, amphetamines can stimulate uterine contractions, increasing the risk of premature delivery.
Infants born to mothers taking amphetamines during pregnancy have an increased risk of premature delivery and low birth weight. Monitor infants born to mothers taking amphetamines for symptoms of withdrawal such as feeding difficulties, irritability, agitation, and excessive drowsiness. Data Animal Data Amphetamine, in the enantiomer ratio present in amphetamine extended-release orally disintegrating tablets, (d- to l-ratio of 3:1), had no apparent effects on embryofetal morphological development or survival when orally administered to pregnant rats and rabbits throughout the period of organogenesis at doses of up to 6 and 16 mg/kg/day, respectively.
These doses are approximately 2 and 12 times, respectively, the maximum recommended human dose (MRHD) for adolescents of 12.5 mg/day (as base), on a mg/m 2 body surface area basis. Fetal malformations and death have been reported in mice following parenteral administration of d-amphetamine doses of 50 mg/kg/day (approximately 10 times the MRHD for adolescents on a mg/m 2 basis) or greater to pregnant animals. Administration of these doses was also associated with severe maternal toxicity.
A study was conducted in which pregnant rats received daily oral doses of amphetamine (d- to l-enantiomer ratio of 3:1, the same as in amphetamine extended-release orally disintegrating tablets) of 2, 6, and 10 mg/kg from gestation day 6 to lactation day 20. These doses are approximately 0.8, 2, and 4 times the MRHD for adolescents of 12.5 mg/day (as base), on a mg/m 2 basis. All doses caused hyperactivity and decreased weight gain in the dams.
A decrease in pup survival was seen at all doses. A decrease in pup bodyweight was seen at 6 and 10 mg/kg which correlated with delays in developmental landmarks. Increased pup locomotor activity was seen at 10 mg/kg on day 22 postpartum but not at 5 weeks post-weaning. When pups were tested for reproductive performance at maturation, gestational weight gain, number of implantations, and number of delivered pups were decreased in the group whose mothers had been given 10 mg/kg.
A number of studies in rodents indicate that prenatal or early postnatal exposure to amphetamine (d- or d, l-), at doses similar to those used clinically, can result in long-term neurochemical and behavioral alterations. Reported behavioral effects include learning and memory deficits, altered locomotor activity, and changes in sexual function.

6.1Clinical Trials Experience
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. The safety of amphetamine extended-release orally disintegrating tablets has been established from adequate and well-controlled studies of single-entity amphetamine product extended-release (MAS ER) capsules [see Clinical Studies ( 14 )] .
The adverse reactions of MAS ER capsules in these adequate and well-controlled studies are described below. The premarketing development program for MAS ER included exposures in a total of 1,315 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 years) were evaluated in two controlled clinical studies, one open-label clinical study, and two single-dose clinical pharmacology studies (N=40).
Adverse Reactions Leading to Discontinuation of Treatment The most frequent adverse reactions leading to discontinuation of MAS ER in controlled and uncontrolled, multiple-dose clinical trials of pediatric patients ages 6 to 12 years (N=595) were anorexia (loss of appetite) (2.9%), insomnia (1.5%), weight loss (1.2%), emotional lability (1%), and depression (0.7%). In a separate placebo-controlled 4-week study in pediatric patients ages 13 to 17 years with ADHD, five patients (2.1%) discontinued treatment due to adverse events among MAS ER-treated patients (N=233) compared to 0% 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 MAS ER-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 MAS ER-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 MAS ER-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). Adverse Reactions Occurring in Clinical Trials Adverse reactions reported in a 3-week clinical trial of pediatric patients 6 to 12 years of age and a 4-week clinical trial in pediatric patients 13 to 17 years of age and adults, respectively, treated with MAS ER or placebo are presented in the tables below.

6.2Adverse Reactions from Clinical Trials and Spontaneous Postmarketing Reports of Other Amphetamine Products
The following adverse reactions are from clinical trials and spontaneous postmarketing reports of other amphetamine products in pediatric patients and adults with ADHD. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure. Cardiovascular: Palpitations, sudden death, myocardial infarction.
There have been isolated reports of cardiomyopathy associated with chronic amphetamine use. Central Nerv
