Synopsis

Benzodiazepine use disorder is a condition characterized by addiction to and overuse of benzodiazepines. Benzodiazepines are commonly prescribed hypnotic and anxiolytic agents often used to treat panic disorder, social anxiety disorder, insomnia, and acute agitation. They are also used to manage the symptoms of alcohol withdrawal and to counteract adverse effects of antidepressant overdoses. Due to their generally rapid onset and short duration of action, benzodiazepines have addictive properties, and patients who are prescribed benzodiazepines have a high propensity for developing an overuse disorder. Easy availability of these medications contributes to their high rate of abuse.

Risk factors for abuse include other drug or alcohol dependence, chronic pain, personality disorder, depressive disorder, sleep disorder, and certain neuromuscular disorders.

Patients may stockpile prescription drugs, seek multiple prescriptions from multiple health care providers, acquire medications from other users, and exaggerate their symptoms to acquire larger quantities and higher doses of benzodiazepines.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) classifies substance abuse from mild to severe. The criteria address signs of cravings, tolerance, loss of control, loss of interest in favorite activities, avoidance of responsibilities, and withdrawal symptoms upon abstinence.

Health care providers are advised against prescribing multiple benzodiazepines. When they are prescribed, it is advisable to use short-term prescriptions and to seek alternative therapies in older or high-risk patients. Long-term use of benzodiazepines has been shown to increase tolerance.

Adverse effects of benzodiazepine use include amnesia (memory loss), psychomotor impairment, ataxia, altered mental status, slurred speech, rebound anxiety, withdrawal symptoms, drowsiness, lethargy, disturbed concentration, feeling "hungover," uncoordinated muscular movement, and hypotonia. These effects increase the likelihood of impaired driving, falls, and fractures.

Benzodiazepine overdose or poisoning can occur when ingested in a high dose alone or in combination with ethanol or other drugs, particularly depressants. Toxicity can induce a state of excessive drowsiness, delirium, psychosis, seizures, stupor, or coma. Patients with a benzodiazepine use disorder are particularly prone to overdoses due to increased drug tolerance and often the use of escalating doses.
