Use of anorectic amphetamine-like drugs by Brazilian women.

The history of anorectic drug use was investigated in 2370 subjects in São Paulo and Brasília cities. Socio-demographic data and the number of previous treatments to lose weight were obtained. When the last treatment was drug-based, the substance(s) used, its duration, the occurrence of adverse reactions, and whether it was adequate were studied. There was a prevalence of female patients, 92.7%, in both cities and as many as 72.4% of them had already undergone from 1 to >10 previous treatments. Out of those patients, 75.37% had undergone pharmacological treatment, 79.2% of those with amphetamine-like anorectic drugs. Treatment was longer than 3 months in half of the cases, and 60% of the subjects had a Body Mass Index below 29.9. Over 50% of the subjects was given amphetamine-like drugs through compounded formulas containing four or more substances, which had been specifically tailored by the doctor for each patient. On the other hand, 86.3% of all the subjects reported adverse reactions to the amphetamine-like drugs, 37.4% of them sought medical advice, and 3.9% required hospitalization. In conclusion, the use of amphetamine-like drugs in Brazil is particularly prevalent among women and this use is strongly related to the culture of slimness as a symbol of beauty.
