Chlordiazepoxide (brand Librium) is a long-acting benzodiazepine indicated for the management of anxiety disorders (or short-term relief of anxiety symptoms), withdrawal symptoms of acute alcoholism, and preoperative apprehension/anxiety (label). Long half-life (24–48 hours on label) can smooth withdrawal symptoms but increases accumulation and next-day impairment risk; it is not a good fit for chronic “as needed” anxiety prescribing.

- Alcohol withdrawal treatment should follow a structured protocol with frequent monitoring; converting withdrawal regimens into indefinite outpatient benzodiazepine therapy is generally avoided once the acute phase resolves.
- Boxed warning: benzodiazepines plus opioids can cause fatal respiratory depression. Co-prescribing with opioids is generally avoided, and combining with alcohol or other sedatives increases risk.
- The compare view, the chlordiazepoxide evidence feed, and the chlordiazepoxide print page can support safe-use counseling and shared decision-making.
- In older or medically fragile patients, oversedation and falls are common failure modes; conservative dosing and frequent reassessment are typical (label).
- For chronic anxiety, psychotherapy and SSRI/SNRI-based strategies are typically preferred over long-term benzodiazepine maintenance (guidelines).
Dosing & Formulations
Capsules: 5 mg, 10 mg, 25 mg (label). Label dosing is divided and varies by indication and severity; use the lowest effective dose for the shortest feasible duration, with frequent reassessment (label).

- For alcohol withdrawal, follow a protocolized symptom-triggered or fixed-dose taper strategy and adjust based on vitals/withdrawal scoring rather than subjective anxiety alone (guidelines).
- In elderly or debilitated patients, limit doses initially (often 10 mg per day or less) and titrate cautiously to reduce ataxia and oversedation (label).
Monitoring & Risks
Boxed warning: Concomitant use with opioids can cause profound sedation, respiratory depression, coma, and death (label). Accumulation risk: long half-life increases next-day impairment, delirium, and fall risk—especially in older adults.

- Dependence and withdrawal: monitor for tolerance and withdrawal symptoms; abrupt discontinuation after prolonged use is avoided.
- Respiratory disease and sedative co-prescriptions amplify risk; screen for sleep apnea/COPD and alcohol use before renewing.
Drug Interactions
Additive CNS and respiratory depression with opioids, alcohol, antihistamines, and other sedatives; stacking sedatives is generally avoided. Long half-life means interactions can have prolonged clinical impact; changes in co-prescribed sedatives should prompt reassessment for oversedation and falls.

- If concomitant sedatives are unavoidable, keep doses conservative and increase follow-up frequency.
Practice Notes
Alcohol withdrawal is typically managed with a protocolized approach and an explicit taper/stop date; converting withdrawal prescriptions into chronic anxiety management is generally avoided. For chronic anxiety, psychotherapy and SSRI/SNRI plans are typically prioritized, with benzodiazepines reserved for time-limited, goal-directed use.

- If discontinuing after extended use, gradual tapering and monitoring for rebound anxiety/insomnia and functional relapse are typical.
- In older adults, safer alternatives are often preferred and necessity is reassessed frequently; long half-life increases fall and delirium risk.
