Chlordiazepoxide
Aliases: Seren, Mitran, Librium, Clindex, Tropium
Summary
Chlordiazepoxide was the first benzodiazepine synthesized and is primarily prescribed for anxiety disorders and acute alcohol withdrawal. It has a long half-life and produces long-lasting active metabolites, making it useful for tapering but inappropriate for elderly patients due to accumulation risk. Abrupt discontinuation after prolonged use can cause life-threatening withdrawal including seizures.

Tolerance
Tolerance Decay
Benzodiazepine tolerance builds to sedative/anxiolytic effects within days to weeks of regular use and decays slowly over weeks after cessation. Cross‑tolerance within GABA-A positive modulators is substantial but incomplete; individual variability is large. Data derived from clinical guidance and community reports; figures are illustrative, not prescriptive.
