From the Guidelines

Intravenous diazepam is the recommended medication for managing benzodiazepine withdrawal in an inpatient setting. The typical dosing regimen begins with 5-10 mg IV diazepam, which can be repeated every 5-10 minutes until symptoms are controlled, followed by scheduled dosing every 1-4 hours as needed, as suggested by the management of alcohol withdrawal syndrome guidelines 1. For severe withdrawal, continuous infusion may be necessary, typically starting at 0.03-0.1 mg/kg/hr.

  • Key considerations for IV diazepam include:
    • Monitoring for signs of overdose, such as respiratory depression
    • Adjusting the dose based on the patient's response and medical history
    • Using alternative medications, such as lorazepam (1-2 mg IV), in patients with liver dysfunction
  • Supportive care, including IV fluids, electrolyte replacement, and thiamine supplementation, should accompany pharmacological management, as outlined in the guidelines for the management of alcoholic liver disease 1.
  • Close monitoring of vital signs, mental status, and withdrawal symptoms using validated tools is essential during treatment.
  • The choice of diazepam is based on its long half-life and active metabolites, which provide smoother control of withdrawal symptoms and reduce the risk of breakthrough symptoms between doses, although this specific information is not directly mentioned in the provided study 1, it is a well-established principle in the management of benzodiazepine withdrawal.

From the FDA Drug Label

For patients using lorazepam injection more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue lorazepam injection Acute withdrawal signs and symptoms associated with benzodiazepines have included abnormal involuntary movements, anxiety, blurred vision, depersonalization, depression, derealization, dizziness, fatigue, gastrointestinal adverse reactions (e.g., nausea, vomiting, diarrhea, weight loss, decreased appetite), headache, hyperacusis, hypertension, irritability, insomnia, memory impairment, muscle pain and stiffness, panic attacks, photophobia, restlessness, tachycardia, and tremor

The recommended IV medication for benzodiazepine (benzo) withdrawal in an inpatient setting is lorazepam (IV), and it should be tapered gradually to reduce the risk of withdrawal reactions 2.

From the Research

Benzodiazepine Withdrawal Management

In the inpatient setting, managing benzodiazepine withdrawal requires careful consideration of the patient's overall health and the severity of their withdrawal symptoms.

  • The use of a single dose of phenobarbital for inpatient management of benzodiazepine withdrawal has been explored in a case report 3, suggesting it as a viable alternative to prolonged outpatient tapers.
  • Pharmacological interventions such as valproate, tricyclic antidepressants, pregabalin, captodiame, paroxetine, and flumazenil have been studied for their potential in facilitating benzodiazepine discontinuation and managing withdrawal symptoms 4.
  • A stepwise approach to discontinuing benzodiazepines, potentially incorporating agents like carbamazepine, imipramine, valproate, and trazodone, has been proposed 5.

IV Medication for Benzodiazepine Withdrawal

For IV medication specifically, the evidence points towards:

  • Phenobarbital as a potential option for managing benzodiazepine withdrawal in the inpatient setting, given its use in a case report 3.
  • The importance of considering the patient's individual needs and the severity of their withdrawal symptoms when selecting an IV medication for benzodiazepine withdrawal.

Considerations for Inpatient Setting

In the inpatient setting, it's crucial to:

  • Monitor patients closely for complications such as seizures and psychotic reactions, especially during the withdrawal process 6.
  • Consider the patient's history of substance use and potential for polysubstance use, as seen in the implementation of an outpatient benzodiazepine taper protocol 7.
  • Develop personalized treatment plans that may include a combination of pharmacological interventions and supportive care to manage benzodiazepine withdrawal effectively.
