Benzodiazepines and medications acting on benzodiazepine receptors that do not have a benzodiazepine structure (z-drugs) have been viewed by some experts and regulatory bodies as having limited benefit and significant risks. Data presented in this article support the use of these medications as treatments of choice for acute situational anxiety, chronic anxiety disorders, insomnia, alcohol withdrawal syndromes, and catatonia. They may also be useful adjuncts in the treatment of anxious depression and mania, and for medically ill patients. Tolerance develops to sedation and possibly psychomotor impairment, but not to the anxiolytic effect of benzodiazepines. Sedation can impair cognitive function in some patients, but assertions that benzodiazepines increase the risk of dementia are not supported by recent data. Contrary to popular opinion, benzodiazepines are not frequently misused or conduits to misuse of other substances in patients without substance use disorders who are prescribed these medications for appropriate indications; most benzodiazepine misuse involves medications that are obtained from other people. Benzodiazepines are usually not lethal in overdose except when ingested with other substances, especially alcohol and opioids. Benzodiazepines comprise one of the few classes of psychotropic medication the mechanisms of action of which are clearly delineated, allowing for greater precision in their clinical use. These medications, therefore, belong in the therapeutic armamentarium of the knowledgeable clinician. Keywords: Benzodiazepines, Anxiety, Mood disorders, Agitation, Catatonia
