Interview by Peter Simons. Dr. Mark Horowitz is a training psychiatrist and researcher and recently co-authored, with Dr. David Taylor, a review of antidepressant withdrawal that was published in Lancet Psychiatry, which we've written about here at Mad in America (see here). Their article suggests that tapering off antidepressants over months or even years is more successful at preventing withdrawal symptoms than a quick discontinuation of two to four weeks. Dr. Horowitz is currently completing his psychiatry training in Sydney, Australia, and has completed a PhD in the neurobiology of antidepressants at the Institute of Psychiatry at King's College, London. He is a clinical research fellow on the RADAR study run by University College, London. His research work focuses on pharmacologically informed ways of tapering patients off of medication. He plans to conduct studies examining the best methods for tapering medications in order to develop evidence based guidelines to assist patients and doctors.
