What is Librium (chlordiazepoxide) used for?

Uses of Librium (Chlordiazepoxide)

Librium (chlordiazepoxide) is primarily indicated for the management of alcohol withdrawal syndrome, anxiety disorders, and preoperative anxiety. 1

Primary Indications

• Alcohol Withdrawal Syndrome (AWS): Chlordiazepoxide is considered a "gold standard" treatment for AWS due to its efficacy in reducing withdrawal symptoms and preventing seizures and delirium tremens 2
• Anxiety Disorders: Indicated for management of anxiety disorders or short-term relief of anxiety symptoms 1
• Preoperative Anxiety: Used for relief of apprehension and anxiety before surgical procedures 1

Alcohol Withdrawal Management

Mechanism and Benefits

• Long-acting benzodiazepine that works through activation of gamma-aminobutyric acid (GABA) receptors, providing anxiety relief, sedation, and somnolence 2
• Particularly effective in preventing withdrawal seizures and delirium tremens in patients with alcohol dependence 2
• Typical dosing for AWS: 25-100 mg orally every 4-6 hours, with dose titration based on symptom severity 2

Clinical Considerations

• Hepatic Function: Caution is warranted in patients with liver disease as chlordiazepoxide requires hepatic metabolism 3

  • In patients with hepatic insufficiency, chlordiazepoxide metabolism may be delayed, potentially leading to "dose-stacking" and prolonged sedation 3
  • For patients with severe liver disease, shorter-acting benzodiazepines like lorazepam may be safer alternatives 2, 3

• Efficacy: Studies have demonstrated that chlordiazepoxide is highly effective in treating alcohol withdrawal symptoms compared to baseline measurements 4, 5

Anxiety Management

• Indicated for anxiety disorders or short-term relief of anxiety symptoms 1
• The FDA notes that anxiety associated with everyday life stress typically doesn't require anxiolytic treatment 1
• Long-term efficacy (beyond 4 months) has not been established through systematic clinical studies 1

Important Precautions

• Potential for Dependence: Like other benzodiazepines, chlordiazepoxide can produce tolerance and dependence with both short and long-term administration 6
• Duration of Use: Physicians should periodically reassess the usefulness of the drug for individual patients, particularly for long-term use 1
• Monitoring: Regular assessment of continued need and response is recommended, especially in patients with liver disease 3

Comparison to Other Agents

• Studies comparing chlordiazepoxide to lorazepam found similar efficacy in attenuating uncomplicated alcohol withdrawal 7
• When compared to other agents like tiapride for alcohol withdrawal, chlordiazepoxide showed statistically significant superior efficacy in patient-reported outcomes 5
• Chlordiazepoxide was the first benzodiazepine introduced (1963), developed as an alternative to barbiturates with the goal of reducing sedative properties and addiction potential 6
