Warning: Abuse, Misuse, And Addiction
Dextroamphetamine sulfate extended-release capsule has a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants, including dextroamphetamine sulfate extended-release capsules, can result in overdose and death [see Overdosage], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.
Before prescribing dextroamphetamine sulfate extended-release capsules, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks, proper storage of the drug, and proper disposal of any unused drug. Throughout dextroamphetamine sulfate extended-release capsules treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction [see Warnings and Drug Abuse and Dependence].

Clinical Pharmacology
Amphetamines are noncatecholamine, sympathomimetic amines with CNS stimulant activity. Peripheral actions include elevations of systolic and diastolic blood pressures and weak bronchodilator and respiratory stimulant action. There is neither specific evidence that clearly establishes the mechanism whereby amphetamines produce mental and behavioral effects in children, nor conclusive evidence regarding how these effects relate to the condition of the central nervous system.
Dextroamphetamine sulfate extended-release capsules are formulated to release the active drug substance in vivo in a more gradual fashion than the standard formulation, as demonstrated by blood levels. The formulation has not been shown superior in effectiveness over the same dosage of the standard, noncontrolled-release formulations given in divided doses.
Pharmacokinetics
The pharmacokinetics of the tablet and extended-release capsule were compared in 12 healthy subjects. The extent of bioavailability of the extended-release capsule was similar compared to the immediate-release tablet. Following administration of three 5-mg tablets, average maximal dextroamphetamine plasma concentrations (Cmax) of 36.6 ng/mL were achieved at approximately 3 hours.
Following administration of one 15-mg extended-release capsule, maximal dextroamphetamine plasma concentrations were obtained approximately 8 hours after dosing. The average Cmax was 23.5 ng/mL. The average plasma T1/2; was similar for both the tablet and extended-release capsule and was approximately 12 hours. In 12 healthy subjects, the rate and extent of dextroamphetamine absorption were similar following administration of the extended-release capsule formulation in the fed (58 gm to 75 gm fat) and fasted state.
Indications And Usage
Dextroamphetamine sulfate extended-release capsules are indicated in:
Narcolepsy
Attention Deficit Disorder with Hyperactivity
As an integral part of a total treatment program that typically includes other measures (psychological, educational, social) for patients (ages 6 years to 16 years) with this syndrome. A diagnosis of Attention Deficit Hyperactivity Disorder (ADHD; DSM-IV) implies the presence of the hyperactive-impulsive or inattentive symptoms that caused impairment and were present before age 7 years. The symptoms must cause clinically significant impairment, e.g., in social, academic, or occupational functioning, and be present in 2 or more settings, e.g., school (or work) and at home. The symptoms must not be better accounted for by another mental disorder. For the Inattentive Type, at least 6 of the following symptoms must have persisted for at least 6 months: lack of attention to details/careless mistakes; lack of sustained attention; poor ulener; failure to follow through on tasks; poor organization; avoids tasks requiring sustained mental effort; loses things; easily distracted; forgetful. For the Hyperactive-Impulsive Type, at least 6 of the following symptoms must have persisted for at least 6 months: fidgeting/squirming; leaving seat; inappropriate running/climbing; difficulty with quiet activities; “on the go”; excessive talking; blurting answers; can’t wait turn; intrusive. The Combined Type requires both inattentive and hyperactive-impulsive criteria to be met.
Special Diagnostic Considerations
Specific etiology of this syndrome is unknown, and there is no single diagnostic test. Adequate diagnosis requires the use of medical and special psychological, educational, and social resources. Learning may or may not be impaired. The diagnosis must be based upon a complete history and evaluation of the patient and not solely on the presences of the required number of DSM-IV characteristics.
Need for Comprehensive Treatment Program
Dextroamphetamine sulfate extended-release is indicated as an integral part of a total treatment program for ADHD that may include other measures (psychological, educational, social) for patients with this syndrome. Drug treatment may not be indicated for all patients with this syndrome. Stimulants are not intended for use in patients who exhibit symptoms secondary to environmental factors and/or other primary psychiatric disorders, including psychosis. Appropriate educational placement is essential and psychosocial intervention is often helpful. When remedial measures alone are insufficient, the decision to prescribe stimulant medication will depend upon the physician’s assessment of the chronicity and severity of the patient’s symptoms.
Contraindications
In patients known to be hypersensitive to amphetamine, or other components of dextroamphetamine sulfate extended-release. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other amphetamine products [see Adverse Reactions].
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 Drug Interactions].
Warnings
Abuse, Misuse, and Addiction
Dextroamphetamine sulfate extended-release capsule has a high potential for abuse and misuse. The use of dextroamphetamine sulfate extended-release capsules exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Dextroamphetamine sulfate extended-release capsules can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse and Dependence]. Misuse and abuse of CNS stimulants, including dextroamphetamine sulfate extended-release capsules can result in overdose and death [see Overdosage], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.
Before prescribing dextroamphetamine sulfate extended-release capsules, 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 sulfate in a safe place, preferably locked, and instruct patients to not give dextroamphetamine sulfate extended-release capsules to anyone else. Throughout dextroamphetamine sulfate extended-release capsules treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
Risks to Patients with Serious Cardiac Disease
Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended ADHD dosages.
Avoid dextroamphetamine sulfate extended-release capsule use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease.
Increased 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).
Monitor all patients for potential tachycardia and hypertension.
Psychiatric 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 Disease
CNS stimulants may induce a manic or mixed episode in patients. Prior to initiating treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, or depression).
New Psychotic or Manic Symptoms
CNS stimulants, at recommended doses, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients without a 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 approximately 0.1% of CNS stimulant-treated patients, compared with 0% of placebo-treated patients. If such symptoms occur, consideration discontinuing dextroamphetamine sulfate extended-release.
Long-Term Suppression of Growth in Pediatric Patients
CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients, including dextroamphetamine sulfate extended-release. Closely monitor growth (weight and height) in dextroamphetamine sulfate extended-release-treated pediatric patients treated with CNS stimulants.
Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted [see Precautions, Pediatric Use].
Seizures
There is some clinical evidence that stimulants may lower the convulsive threshold in patients with prior history of seizures, in patients with prior EEG abnormalities in absence of seizures, and, very rarely, in patients without a history of seizures and no prior EEG evidence of seizures. In the presence of seizures, the drug should be discontinued.
Peripheral Vasculopathy, including Raynaud’s phenomenon
Stimulants, including dextroamphetamine sulfate extended-release, 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 post-marketing reports and at therapeutic dosages in all age groups throughout the course of treatment. Signs and symptoms generally improve after dosage reduction or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during dextroamphetamine sulfate extended-release capsules treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for Dextroamphetamine sulfate-treated patients who develop signs or symptoms of peripheral vasculopathy.
Serotonin 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]. Amphetamines and amphetamine derivatives are known to be metabolized, to some degree, by cytochrome P450 2D6 (CYP2D6) and display minor inhibition of CYP2D6 metabolism [see Clinical Pharmacology]. The potential for a pharmacokinetic interaction exists with the coadministration of CYP2D6 inhibitors which may increase the risk with increased exposure to dextroamphetamine sulfate extended-release. In these situations, consider an alternative non-serotonergic drug or an alternative drug that does not inhibit CYP2D6 [see Drug Interactions].
Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Concomitant use of dextroamphetamine sulfate extended-release with MAOI drugs is contraindicated [see Contraindications].
Discontinue treatment with dextroamphetamine sulfate extended-release and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of dextroamphetamine sulfate extended-release with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate dextroamphetamine sulfate extended-release with lower doses, monitor patients for the emergence of serotonin syndrome during drug initiation or titration, and inform patients of the increased risk for serotonin syndrome.
Motor and Verbal Tics, and Worsening of Tourette’s Syndrome
CNS stimulants, including amphetamine sulfate, have been associated with the onset or exacerbation of motor and verbal tics. Worsening of Tourette’s syndrome has also been reported. Before initiating dextroamphetamine sulfate extended-release capsules, 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 with dextroamphetamine sulfate extended-release capsules, and discontinue treatment if clinically appropriate.
Precautions
General
The least amount feasible should be prescribed or dispensed at 1 time in order to minimize the possibility of overdosage.
Information for Patients
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Abuse, Misuse, and Addiction
Educate patients and their families about the risks of abuse, misuse, and addiction of dextroamphetamine sulfate extended-release, which can lead to overdose and death, and proper disposal of any unused drug [see Warnings, Drug Abuse and Dependence, Overdosage]. Advise patients to store dextroamphetamine sulfate extended-release in a safe place, preferably locked, and instruct patients to not give dextroamphetamine sulfate extended-release to anyone else.
Risks to Patients with Serious Cardiac Disease
Advise patients that there are potential risks to patients with serious cardiac disease, including sudden death, with dextroamphetamine sulfate extended-release use. Instruct patients to contact a healthcare provider immediately if they develop symptoms such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease [see Warnings].
Increased Blood Pressure and Heart Rate
Instruct patients that dextroamphetamine sulfate extended-release can elevate blood pressure and heart rate [see Warnings].
Psychiatric Adverse Reactions
Advise patients that dextroamphetamine sulfate extended-release, at recommended doses, can cause psychotic or manic symptoms, even in patients without prior history of psychotic symptoms or mania [see Warnings].
Long-Term Suppression of Growth in Pediatric Patients
Advise patients that dextroamphetamine sulfate extended-release may cause slowing of growth and weight loss in pediatric patients [see Warnings]. Circulation problems in fingers and toes [Peripheral vasculopathy, including Raynaud’s phenomenon]
- Instruct patients beginning treatment with dextroamphetamine sulfate extended-release about the risk of peripheral vasculopathy, including Raynaud’s phenomenon, and associated signs and symptoms: fingers or toes may feel numb, cool, painful, and/or may change color from pale, to blue, to red.
- Instruct patients to report to their physician any new numbness, pain, skin color change, or sensitivity to temperature in fingers or toes.
- Instruct patients to call their physician immediately with any signs of unexplained wounds appearing on fingers or toes while taking dextroamphetamine sulfate extended-release.
- Further clinical evaluation (e.g., rheumatology referral) may be appropriate for certain patients [see Warnings].
Motor and Verbal Tics, and Worsening of Tourette’s Syndrome
Advise patients that motor and verbal tics and worsening of Tourette’s Syndrome may occur during treatment with dextroamphetamine sulfate extended-release. Instruct the patients to notify their healthcare provider if emergence or worsening of tics or Tourette’s syndrome occurs [see Warnings].
Drug Interactions
Acidifying Agents
Lower blood levels and efficacy of amphetamines. Increase dose based on clinical response. Examples of acidifying agents include gastrointestinal acidifying agents (e.g., guanethidine, reserpine, glutamic acid HCl, ascorbic acid) and urinary acidifying agents (e.g., ammonium chloride, sodium acid phosphate, methenamine salts).
Adrenergic Blockers
Adrenergic blockers are inhibited by amphetamines.
Alkalinizing Agents
Increase blood levels and potentiate the action of amphetamine. Coadministration of dextroamphetamine sulfate extended-release and gastrointestinal alkalinizing agents should be avoided. Examples of alkalinizing agents include gastrointestinal alkalinizing agents (e.g., sodium bicarbonate) and urinary alkalinizing agents (e.g. acetazolamide, some thiazides).
Tricyclic Antidepressants
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. Monitor frequently and adjust or use alternative therapy based on clinical response. Examples of tricyclic antidepressants include desipramine, Protriptyline.
CYP2D6 Inhibitors
The concomitant use of dextroamphetamine sulfate extended-release and CYP2D6 inhibitors may increase the exposure of dextroamphetamine sulfate extended-release compared to the use of the drug alone and increase the risk of serotonin syndrome. Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome particularly during dextroamphetamine sulfate extended-release initiation and after a dosage increase. If serotonin syndrome occurs, discontinue dextroamphetamine sulfate extended-release and the CYP2D6 inhibitor [see Warnings, Overdosage]. Examples of CYP2D6 Inhibitors include paroxetine and fluoxetine (also serotonergic drugs), quinidine, ritonavir.
Serotonergic Drugs
The concomitant use of dextroamphetamine sulfate extended-release and serotonergic drugs increases the risk of serotonin syndrome. Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome, particularly during dextroamphetamine sulfate extended-release initiation or dosage increase. If serotonin syndrome occurs, discontinue dextroamphetamine sulfate extended-release and the concomitant serotonergic drug(s) [see Warnings and Precautions]. Examples of serotonergic drugs include selective serotonin reuptake inhibitors (SSRI), serotonin norepinephrine reuptake inhibitors (SNRI), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort.
MAO Inhibitors
Concomitant use of MAOIs and CNS stimulants can cause hypertensive crisis. Potential outcomes include death, stroke, myocardial infarction, aortic dissection, ophthalmological complications, eclampsia, pulmonary edema, and renal failure. Do not administer dextroamphetamine sulfate extended-release concomitantly or within 14 days after discontinuing MAOI [see Contraindications and Warnings]. Examples of MAOIs include selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue.
Proton Pump Inhibitors
Time to maximum concentration (Tmax) of amphetamine is decreased compared to when administered alone. Monitor patients for changes in clinical effect and adjust therapy based on clinical response. An example of a proton pump inhibitor is omeprazole.
Antihistamines
Amphetamines may counteract the sedative effect of antihistamines.
Antihypertensives
Amphetamines may antagonize the hypotensive effects of antihypertensives.
Chlorpromazine
Chlorpromazine blocks dopamine and norepinephrine reuptake, thus inhibiting the central stimulant effects of amphetamines, and can be used to treat amphetamine poisoning.
Ethosuximide
Amphetamines may delay intestinal absorption of ethosuximide.
Haloperidol
Haloperidol blocks dopamine and norepinephrine reuptake, thus inhibiting the central stimulant effects of amphetamines.
Lithium Carbonate
The stimulatory effects of amphetamines may be inhibited by lithium carbonate.
Meperidine
Amphetamines potentiate the analgesic effect of meperidine.
Methenamine Therapy
Urinary excretion of amphetamines is increased, and efficacy is reduced, by acidifying agents used in methenamine therapy.
Norepinephrine
Amphetamines enhance the adrenergic effect of norepinephrine.
Phenobarbital
Amphetamines may delay intestinal absorption of phenobarbital; coadministration of phenobarbital may produce a synergistic anticonvulsant action.
Phenytoin
Amphetamines may delay intestinal absorption of phenytoin; coadministration of phenytoin may produce a synergistic anticonvulsant action.
Propoxyphene
In cases of propoxyphene overdosage, amphetamine CNS stimulation is potentiated and fatal convulsions can occur.
Veratrum Alkaloids
Amphetamines inhibit the hypotensive effect of veratrum alkaloids.
Drug/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.
Carcinogenesis/Mutagenesis
Mutagenicity studies and long-term studies in animals to determine the carcinogenic potential of dextroamphetamine sulfate extended-release have not been performed.
Pregnancy
Dextroamphetamine sulfate extended-release has been shown to have embryotoxic and teratogenic effects when administered to A/Jax mice and C57BL mice in doses approximately 41 times the maximum human dose. Embryotoxic effects were not seen in New Zealand white rabbits given the drug in doses 7 times the human dose nor in rats given 12.5 times the maximum human dose. While there are no adequate and well-controlled studies in pregnant women, there has been 1 report of severe congenital bony deformity, tracheoesophageal fistula, and anal atresia (VATER association) in a baby born to a woman who took dextroamphetamine sulfate with lovastatin during the first trimester of pregnancy. Dextroamphetamine sulfate extended-release should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Infants born to mothers dependent on amphetamines have an increased risk of premature delivery and low birth weight. Also, these infants may experience symptoms of withdrawal as demonstrated by dysphoria, including agitation, and significant lassitude.
Nursing Mothers
Amphetamines are excreted in human milk. Mothers taking amphetamines should be advised to refrain from nursing.
Pediatric Use
Long-term effects of amphetamines in pediatric patients have not been well established. Dextroamphetamine sulfate extended-release is not recommended for use in pediatric patients younger than 6 years of age with Attention Deficit Disorder with Hyperactivity described under INDICATIONS AND USAGE. Clinical experience suggests that in psychotic children, administration of amphetamines may exacerbate symptoms of behavior disturbance and thought disorder. Amphetamines have been reported to exacerbate motor and phonic tics and Tourette’s syndrome. Therefore, clinical evaluation for tics and Tourette’s syndrome in children and their families should precede use of stimulant medications. Data are inadequate to determine whether chronic administration of amphetamines may be associated with growth inhibition; therefore, growth should be monitored during treatment. Drug treatment is not indicated in all cases of Attention Deficit Disorder with Hyperactivity and should be considered only in light of the complete history and evaluation of the child. The decision to prescribe amphetamines should depend on the physician’s assessment of the chronicity and severity of the child’s symptoms and their appropriateness for his or her age. Prescription should not depend solely on the presence of one or more of the behavioral characteristics. When these symptoms are associated with acute stress reactions, treatment with amphetamines is usually not indicated.
Adverse Reactions
Cardiovascular
Palpitations, tachycardia, elevation of blood pressure. There have been isolated reports of cardiomyopathy associated with chronic amphetamine use.
Central Nervous System
Psychotic episodes at recommended doses (rare), overstimulation, restlessness, dizziness, insomnia, euphoria, dyskinesia, dysphoria, tremor, headache, exacerbation of motor and verbal tics, and Tourette’s syndrome.
Gastrointestinal
Dryness of the mouth, unpleasant taste, diarrhea, constipation, intestinal ischemia, and other gastrointestinal disturbances. Anorexia and weight loss may occur as undesirable effects.
Allergic
Urticaria.
Endocrine
Impotence, changes in libido, frequent or prolonged erections.
Musculoskeletal
Rhabdomyolysis.
Skin and Subcutaneous Tissue Disorders
Alopecia.

Drug Abuse And Dependence
Controlled Substance
Dextroamphetamine sulfate is a Schedule II controlled substance.
Abuse
Dextroamphetamine sulfate has a high potential for abuse and misuse which can lead to the development of a substance use disorder, including addiction [see Warnings]. Dextroamphetamine sulfate can be diverted for non-medical use into illicit channels or distribution.
Abuse is the intentional non-therapeutic use of a drug, even once, to achieve a desired psychological or physiological effect. Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a health care provider or for whom it was not prescribed. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence.
Misuse and abuse of amphetamine may cause increased heart rate, respiratory rate, or blood pressure; sweating; dilated pupils; hyperactivity; restlessness; insomnia; decreased appetite; loss of coordination; tremors; flushed skin; vomiting; and/or abdominal pain. Anxiety, psychosis, hostility, aggression, and suicidal or homicidal ideation have also been observed with CNS stimulants abuse and/or misuse. Misuse and abuse of CNS stimulants, including Dextroamphetamine sulfate, can result in overdose and death [see Overdosage], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.
Dependence
Physical Dependence
Dextroamphetamine sulfate may produce physical dependence. Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug.
Withdrawal signs and symptoms after abrupt discontinuation or dose reduction following prolonged use of CNS stimulants including Dextroamphetamine sulfate include dysphoric mood; depression; fatigue; vivid, unpleasant dreams; insomnia or hypersomnia; increased appetite; and psychomotor retardation or agitation.
Tolerance
Dextroamphetamine sulfate may produce tolerance. Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose).
Overdosage
Clinical Effects of Overdose
Overdose of CNS stimulants is characterized by the following sympathomimetic effects:
- Cardiovascular effects including tachyarrhythmias, and hypertension or hypotension. Vasospasm, myocardial infarction, or aortic dissection may precipitate sudden cardiac death. Takotsubo cardiomyopathy may develop.
- CNS effects including psychomotor agitation, confusion, and hallucinations. Serotonin syndrome, seizures, cerebral vascular accidents, and coma may occur.
- Life-threatening hyperthermia (temperatures greater than 104°F) and rhabdomyolysis may develop.
Overdose Management
Consider the possibility of multiple drug ingestion. The pharmacokinetic profile of Dextroamphetamine sulfate should be considered when treating patients with overdose. D-amphetamine is not dialyzable. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
Dosage And Administration
Amphetamines should be administered at the lowest effective dosage and dosage should be individually adjusted. Late evening doses should be avoided because of the resulting insomnia.
Prior to treating patients with dextroamphetamine sulfate extended-release capsules, assess:
- for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings].
- the family history and clinically evaluate patients for motor or verbal tics or Tourette’s syndrome [see Warnings].
Narcolepsy
Usual dose is 5 mg to 60 mg per day in divided doses, depending on the individual patient response.
Narcolepsy seldom occurs in children under 12 years of age; however, when it does, dextroamphetamine sulfate extended-release may be used. The suggested initial dose for patients aged 6 to 12 is 5 mg daily; daily dose may be raised in increments of 5 mg at weekly intervals until an optimal response is obtained. In patients 12 years of age and older, start with 10 mg daily; daily dosage may be raised in increments of 10 mg at weekly intervals until an optimal response is obtained. If bothersome adverse reactions appear (e.g., insomnia or anorexia), dosage should be reduced.
Extended-release capsules may be used for once-a-day dosage wherever appropriate.
Attention Deficit Disorder with Hyperactivity
The extended-release capsule formulation is not recommended for pediatric patients younger than 6 years of age.
In pediatric patients 6 years of age and older, start with 5 mg once or twice daily; daily dosage may be raised in increments of 5 mg at weekly intervals until optimal response is obtained. Only in rare cases will it be necessary to exceed a total of 40 mg per day. Extended-release capsules may be used for once-a-day dosage wherever appropriate.
