title: Olanzapine abuse.
abstract: Olanzapine is a thienobenzodiazepine that blocks especially the serontonin (5-hydroxytryptamine [5-HT]) 5-HT2A and the dopamine D2 receptors as well as muscarinic (M1), histamine (H1), 5-HT2C, 5-HT3 to 5-HT6, adrenergic (α(l)), and D4 receptors. This case report presents an olanzapine abuse. A 48-year-old, primary school graduate, married woman applied to psychiatry clinic with tachycardia, insomnia, and anxiety complaints. In psychiatric evaluations, it was determined that these complaints have been continuing for 15 years at intervals and that she has been using citalopram 40 mg/day and olanzapine 50 mg/day for the last 3 years. As diabetes mellitus was diagnosed in follow-ups, interruption of olanzapine treatment was planned. The patient stated that she started taking the medicine again upon discomfort, increase in anxiety, dysphoria, insomnia, and nervousness, which started just after olanzapine was interrupted. She said that she was feeling dense stress when she did not take the medicine, and she thought that this situation would recover only by taking that medicine and hence she could not discontinue the medicine. In addition to medications with obvious abuse potential such as benzodiazepines and methylphenidate, and other stimulants, abuse of a number of commonly prescribed psychiatric medications has been reported. There are only 2 cases of olanzapine abuse in literature.
