[The Theriaque database and information on side effects of drugs].

The new module of Theriaque data base deals with side effects of drugs. It is composed of 3,300 monographs. One or more nature of side effect appears on each monograph, to correspond to a defined entity; organ or apparatus, syndrome or special type of pharmacological effect. Side effects are attached to either a whole pharmacological or chemical class, either one or several drugs. Side effects of drugs are described at usual dose, or/and in case of overdose. Data are collected from specialized books and publications. Some difficulties were encountered with this work, particularly side effects frequency. Side effects module content is validated with experts in pharmacology or clinicians, their opinion being a determining factor in case of any doubt, especially on causality assessment or frequency.
