1University of British Columbia, Department of Psychiatry , 2255 Wesbrook Mall, Vancouver, BC, V6T 2A1 , Canada.
Introduction:
Individuals affected by trichotillomania (TTM) (hair-pulling disorder) consciously or non-consciously pull out their own body hair. The disorder has recently been incorporated into a chapter entitled, 'Obsessive-Compulsive and Related Disorders' in the diagnostic and statistical manual of mental disorders, fifth edition.
Areas Covered:
The review describes the literature currently available on the pharmacotherapy for TTM, including both randomized controlled trials and open-label trials of pharmacotherapy for TTM in adults or children.
Expert Opinion:
Early work focused on the serotonin reuptake inhibitors; however, the majority of the trials have been negative. There is a small body of evidence focused on pharmacotherapy for TTM. In future, larger trials are required to expand on the preliminary evidence available for N-acetylcysteine, olanzapine and dronabinol in recent trials.
