    Author: Von Mach MA, Weilemann LS.

    Abstract:
    BACKGROUND AND OBJECTIVE: Antidepressant drugs are frequently used in deliberate self-poisoning resulting in a major risk for the patients due to their cardiac and central-nervous toxicity. In the present study the cases of intoxications consulting our Poison Center should be analysed illustrating recent results and trends about self-poisoning with antidepressants. PATIENTS AND METHODS: During the study period from 1995 to 2001 35 394 inquiries concerning deliberate self-poisoning were registered in our Poison Center. The substance used, age and gender of the patient as well as the degree of the observed symptoms were documented. Thereby, antidepressant drugs were grouped in tricyclic antidepressants (TCA), selective serotonin reuptake inhibitors (SSRI) and other antidepressants. RESULTS: The use of antidepressants in deliberate self-poisoning continuously increased during the study period from 17.3 % to 22.9 % with SSRI and other antidepressants being observed more frequently as compared to TCA. Antidepressant drugs were mainly used from female patients and in the age group between 35 and 54 years. Antidepressant drugs caused severe intoxications and deaths more frequently as the remainder substances with TCA showing higher rates of complications as compared to SSRI and other antidepressants. CONCLUSIONS: In recent years, an increasing importance of antidepressant drugs in deliberate self-poisoning was determined particularly concerning female and middle-aged patients. Due to the changing prescribing patterns larger numbers of intoxications with SSRI and other antidepressants were observed representing an advantage with respect to the reduced rate of complications known for these substances as compared to TCA. Nevertheless, the averagely more severe symptoms present in the three groups of antidepressants in comparison to the remainder drug overdoses demonstrated the need for hospitalization and monitoring of intoxications with antidepressants.
