Other Comments

General:
-The possibility of abuse should be kept in mind when evaluating the desirability of including this drug as part of a weight reduction program. Manifestations of chronic intoxication with anorectic drugs include severe dermatoses, marked insomnia, irritability, hyperactivity, personality changes, and psychosis.
-Management of acute overdosage is largely symptomatic and includes lavage and sedation with a barbiturate. IV phentolamine may be considered if severe hypertension occurs. Experience with hemodialysis and peritoneal dialysis is inadequate in this regard.
-Prolonged use may induce dependence with withdrawal syndrome once treatment is discontinued.

Monitoring:
-Cardiovascular: Cardiac evaluation (baseline/prior to treatment initiation). echocardiogram (during and after treatment), blood pressure
-Metabolic: Weight, waist circumference
-Renal: Renal function (in elderly patients and patients with renal impairment)

Patient advice:
-This drug may cause symptoms including dizziness, drowsiness, and vision problems; avoid driving and other activities such as operating machinery until you know how this drug affects you.
-Avoid drinking alcohol while taking this drug.
