WARNING: ABUSE, MISUSE, AND ADDICTION Amphetamine sulfate tablets have 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 amphetamine 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. Before prescribing amphetamine sulfate tablets, 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 amphetamine sulfate tablets 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 ).
Adult Dosing
General dosing
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.
