Mark Horowitz

Clinical Research Fellow in Psychiatry, UCL


I am a training psychiatrist and Clinical Research Fellow in Psychiatry North East London NHS Foundation Trust (NELFT) and an Honorary Clinical Research Fellow at UCL. I run a Psychotropic drug Deprescribing Clinic in North East London NHS Foundation Trust. I completed a PhD in the neurobiology of depression and the action of antidepressants at the Institute of Psychiatry, Psychology and Neuroscience at King’s College London.

I am an Associate Editor of the journal Therapeutic Advances in Psychopharmacology. I co-authored the recent Royal College of Psychiatry guidance on ‘Stopping Antidepressants’, and my work has informed the recent NICE guidelines on safe tapering of psychiatric medications. I have written several papers about safe approaches to tapering psychiatric medications including publications in The Lancet Psychiatry, JAMA Psychiatry and Schizophrenia Bulletin.

I have an interest in rational psychopharmacology, the way in which psychiatric drugs are often mis-represented to the public and safely deprescribing these drugs. I have experienced the difficulty of coming off psychiatric medications first hand which has informed much of my work.
