Treating Trichotillomania with Olanzapine

Trichotillomania (TTM) is characterized by repetitive pulling of one’s hair leading to hair loss and problems in social, occupational, or other important areas of functioning. Often individuals with TTM try to decrease or stop hair pulling, however are often unsuccessful without treatment. Community prevalence studies suggest that TTM is a common disorder with point prevalence estimate of 0.5% to 2.0% and with significant psychological comorbidity. Of note, people with TTM are often embarrassed about their condition, so epidemiology data may be underestimated compared to the true prevalence of this condition. The female to male ratio for this condition is 4:1. If untreated, trichotillomania is a chronic illness that often results in substantial psychosocial dysfunction and in rare cases, can lead to life-threatening medical problems. Thus, control of the hair pulling is critical for maintaining long-term health and quality of life. Olanzapine is one of several treatment options for TTM. It is important for psychiatrists to work with their patients to determine which treatment is best for them
