[Developing a terminology in the French language for clinical practice and research in drug safety].

While several attempts have been made to clarify the English terminology of drug-related iatrogeny, a consensus has still not been reached in the French language. We set up a multidisciplinary task force to propose a terminology that differs from the one used in pharmacovigilance and risk management. We prefer the term "adverse drug event" (ADE) over "adverse drug reaction", and recommend avoiding the term "adverse event", which is too general.
