The Royal College of Psychiatrists has published a leaflet with the results of a survey about coming off antidepressants, which I mentioned in a previous post. Generally, I think this is a helpful leaflet. However, it ends with a throw-away remark, "We would like to reassure readers that despite some people having symptoms of withdrawal when stopping antidepressants, antidepressants are not addictive".
I think what is meant is that there is no evidence that the body gets addicted with antidepressants. However, people can get psychologically addicted and it seems confusing to restrict the use of the term 'addiction' to physical addiction. GlaxoSmithKline, the makers of paroxetine, eventually dropped its insistence that paroxetine is not addictive, I think at least partly because of this confusion (see Guardian article).
Helpfully, the survey confirms that the primary symptom of antidepressant discontinuation is anxiety. This would fit with my argument that antidepressant discontinuation problems are due to psychological dependence (see my Antidepressant discontinuation reactions webpage and my book chapter Why were doctors so slow to recognise antidepressant discontinuation problems?)
