Withdrawal is treated by tapering the benzodiazepine dosage or substituting another benzodiazepine such as clonazepam. Benzodiazepine intoxication usually occurs only with large overdoses, although intoxication can last for days in a patient with hepatic disease. Lorazepam and oxazepam are not metabolized by the liver and can be prescribed to the patient in liver failure without causing an overdose.
Intoxication is usually treated with supportive measures and close observation for signs of withdrawal. Parenteral flumazenil immediately reverses benzodiazepine intoxication—which may assist both diagnosis and treatment—but its potential to cause seizures20 decreases this antagonist’s clinical usefulness.
Because benzodiazepine addiction often begins with prescribed medication, emergency department personnel can educate both patients and prescribers. Medications such as diazepam, lorazepam, and alprazolam are relatively safe short-term soporific agents, but use for more than a few weeks often leads to physical dependence and/or addiction. Emergency personnel can help the patient and prescriber switch to a treatment with fewer side effects and less danger of addiction.
Summary
Addicts do often change their destructive behavior when faced with increasing consequences such as job loss, relationship problems, financial difficulties, and physical deterioration. Emergencies related to drug and alcohol abuse can serve as learning experiences. Emergency department psychiatrists and other clinicians can use these crises as opportunities to help the addict:
- examine the consequences of substance use
- and change the destructive behaviors that lead to medical and social consequences.
