This article analyzes the role of pharmaceuticals in human poisoning in Brazil from 1993 to 1996, based on data from the National Network of Poison Control Centers. Results are presented according to cause, age group, sex, and evolution. The paper discusses measures aimed at preventing this serious public health problem, which primarily impacts children under five years of age in accidents caused by inappropriate use of medicines. The authors also analyze the association between female gender and deaths caused by intentional intake of drugs.

General concern about increasing reports of emergencies caused by or attributed to the exposure of human beings to various toxic agents has created demand for assessing the informational performance of a Brazilian network of 34 poison control centers (PCCs), located in different regions of the country and pertaining to the National Poison Information System (SINITOX). The primary purpose of these PCCs is to inform the public, prevent cases of poisoning, and provide medical care. This paper analyzes the available resources for identifying cases of poisoning, preventing new occurrences, and monitoring the consequences of toxic agents. This paper also analyzes data recorded front 1990 to 1992. The objective is to identify the main constraints to using health-data and management information as decision-making tools at the local level.
