Clinical summary
Indications and usage INDICATIONS AND USAGE Amphetamine Sulfate Tablets, USP, are indicated for: Narcolepsy Attention Deficit Disorder with Hyperactivity as an integral part of a total treatment program which typically includes other remedial measures (psychological, educational, social) for a stabilizing effect in children with behavioral syndrome characterized by the following group of developmentally inappropriate symptoms: moderate to severe distractibility, short attention span, hyperactivity, emotional lability, and impulsivity. The diagnosis of the syndrome should not be made with finality when these symptoms are only of comparatively recent origin. Nonlocalizing (soft) neurological signs, learning disability, and abnormal EEG may or may not be present, and a diagnosis of central nervous system dysfunction may or not be warranted. Exogenous Obesity as a short term (a few weeks) adjunct in a regimen of weight reduction based on caloric restriction for patient's refractory to alternative therapy, e.g., repeated diets, group programs, and other drugs. The limited usefulness of amphetamines (see CLINICAL PHARMACOLOGY ) should be weighed against possible risks inherent in use of the drug, such as those described below. Dosage and administration DOSAGE AND ADMINISTRATION Regardless of indication, amphetamine should be administered at the lowest effective dosage and dosage should be individually adjusted. Late evening doses should be avoided because of resulting insomnia. Narcolepsy Usual dose is 5 to 60 milligrams 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, Amphetamine Sulfate Tablets 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 optimal response 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 optimal response is obtained. If bothersome adverse reactions appear (e.g., insomnia or anorexia) dosage should be reduced. Give the first dose on awakening; additional doses (5 or 10 mg) at intervals of 4 to 6 hours. Attention Deficit Disorder with Hyperactivity Not recommended for children under 3 years of age. In children from 3 to 5 years of age , start with 2.5 mg daily; daily dosage may be raised in increments of 2.5 mg at weekly intervals until optimal response is obtained. In children 6 years of age or 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 milligrams per day. With tablets give first dose on awakening; additional doses (1 to 2) at intervals of 4 to 6 hours. Where possible, drug administration should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy. Prior to treating patients with Amphetamine Sulfate Tablets 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 ). Exogenous Obesity Usual dosage is up to 30 mg daily, taken in divided doses of 5 to 10 mg, 30 to 60 minutes before meals. Not recommended for this use in children under 12 years of age. Warnings and cautions WARNINGS Abuse, Misuse, and Addiction Amphetamines have a high potential for abuse and misuse. The use of amphetamines exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Amphetamine Sulfate can be diverted for non-medical use into illicit channels or distribution (see DRUG ABUSE and DEPENDENCE ). Misuse and abuse of CNS stimulants, including amphetamines, 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 Amphetamine Sulfate 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 Sulfate Tablets in a safe place, preferably locked, and instruct patients to not give Amphetamine Sulfate Tablets to anyone else. Throughout Amphetamine Sulfate 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 recom

Monitoring
- • WARNINGS Abuse, Misuse, and Addiction Amphetamines have a high potential for abuse and misuse.
- • The use of amphetamines exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction.
- • Amphetamine Sulfate can be diverted for non-medical use into illicit channels or distribution (see DRUG ABUSE and DEPENDENCE ).
- • Misuse and abuse of CNS stimulants, including amphetamines, 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.
Interaction Notes
- • Drug Interactions MAO inhibitors - MAOI antidepressants, as well as a metabolic of furazolidone, slow amphetamine metabolism.
- • This slowing potentiates amphetamines, increasing their effect on the release of norepinephrine and other monoamines from adrenergic nerve endings; this can cause headaches and other signs of hypertensive crisis.
- • A variety of neurological toxic effects and malignant hyperpyrexia can occur, sometimes with fatal results.
- • Serotonergic Drugs- The concomitant use of Amphetamine Sulfate Tablets and serotonergic drugs increases the risk of serotonin syndrome.
