Drug Abuse And Dependence
Controlled Substance: Bontril® PDM (phendimetrazine tartrate) is a Schedule lll controlled substance.
Dependence: Phendimetrazine tartrate is related chemically and pharmacologically to the amphetamines.

Abuse of amphetamines and related drugs may be associated with intense psychological dependence and severe social dysfunction. There are reports of patients who have increased the dosage to many times that recommended. Abrupt cessation following prolonged high dosage administration results in extreme fatigue and mental depression; changes are also noted on the sleep EEG. Manifestations of chronic intoxication with anorectic drugs include severe dermatoses, marked insomnia, irritability, hyperactivity and personality changes. The most severe manifestation of chronic intoxications is psychosis, often clinically indistinguishable from schizophrenia.
